So as you all know I do a lot of track time and Solo events in my SX4 and it has been fun. But unfortunately the lack of aftermarket support and the fact that I want to compete in door-to-door racing makes it impossible to keep dumping money into a dead end. I will continue to track my SX4 but more in a casual way with the autocross events.

To substitute my SX4 I bought this little puppy: 2002 Miata SE. It currently is being put back together as it was all in pieces to be able to install the roll cage.

The car currently has:

Engine:
-1.8L bone stock engine with:
-AEM intake
-Jackson Racing header, Track Dog heatshield and stightback exhaust.
- Aluminum race radiator
- powersteering and a/c delete
- Mazdaspeed motor mounts
- oil cooler and filter relocation kit.

Transmission/drivetrain:
-6 speed manual box
-ACT stage 2 clutch/pressure plate
-4.80 ring and pinion gears on a LSD diff.

Suspension:
-KSport full coilovers
-polyurethane bushings throughout
-Racing Beat front/rear swaybars
-Racing Beat stiffening crossmember
-car comes with stock crossbrace
-Kazera KZ-M Spec Miata wheels (15x7) with Toyo R888 205/45/15 rubber.
-ARP long studs
-Chromoly open lug nuts.

Fuel/Tuning
-Walbro 255lph fuel pump
-Greddy E-Manage piggyback
-AEM wideband

Interior/Exterior/Safety:
-IT/Spec Miata legal roll cage
-Track Dog Racing lightweight aluminum seat and bracket
-6 Point Racequip SFI 3" camlock harness.
-Quick release and steering adapter with NRG steering wheel
-Both doors are gutted.
-Lexan corner windows with air intake openings.
-RH window net
-LH window net (not yet installed)
-Battery cutoff switch (not yet installed)
-APR carbon fiber door mirrors.
-Aerocatch hood latch pins.
-Soft top delete.


A friend of mine and I had to backtrack every cable as it was left in the middle of a wire delete and nothing was identified:

It finally has a dash installed and the wires are all fixed. Deleted 15lbs worth of wiring.

It finally turns on (notice the steering wheel changes to the NRG one in the next pictures).

I'll post more as I complete the build. I'll probably be running in the Improved Touring S (IT-S) class in the future. But first I'll be participating on tge track times and Solo events to get used to the rwd and all the quircks of the Miata.

RWD spec car. . .Awesome!
Will you keep it NA for now ?
FIA/NHRA/SCCA fuel spec system with micron filters (fuel cell with inboard fuel lines) or start with what it came with?

I am excited to watch you build spec car.

Cheers...

AdR
June 1st, 2014, 06:16 AM
Yes it will be N/A. The rules for Improved Touring require the car to be as close to stock as possible. It also requires to keep the stock fuel tank unless otherwise specified.

As per the rules this car classifies in IT-S at a little over 2400lbs with fluids and me in it. The only thing I will need to change from its current form will be the tires since on my region they require the use of a single branded Khumo Ecsta XS tire for the IT classes. It's fine by me as nobody has tire advantage and they come at $100 per tire which is a bargain.

AdR
June 1st, 2014, 06:27 PM
Thanks! It's a tiresome endeavor. Have been working at it non-stop for 3 weeks already. But after it's done it should be a more economical solution to racing due to a bunch of factors including:

1. Uses pump gas instead of the race gas.
2. Plenty of aftermarket support means no need to experiment and test things not done before
3. Cheaper tires on 15" wheels.
4. Plenty of parts everywhere. Ever sonce the demise of ASMC finding parts has been a pain.
5. It's lightweight hence it consumes less fluids overall.
6. The previous owner spent a lot om very nice and expensive parts I will get to enjoy at a bargain price.

And the list goes on and on. :D

The biggest problem for us is that many of us really relied on you to test and experiment new things not done before... I always looked forward to your posts when you raced the SX4. I'm kinda going to miss it!

I'll still autocross the SX4. It's not going anywhere. My wife will be learning car control and the SX4 will be the perfect vehicle in N/A form to do the job.

True... Good thing too! I'm not intrested in boosting my car solely because of the exspense involved (otherwise, if I had the money, I would have jumped at your kit!), but when my son hits school age and I have a bit more disposable income, I would like to make it handle better and try a couple autocrosses myself!

AdR
June 2nd, 2014, 04:52 AM
It's lots of fun and very safe. It's not like you're going to hit a wall nor anything and most autocross setups don't even let you get past 3rd gear. It's all about car control.

Nice! I can understand the economical side of things but I always liked showing up to racing events with a car that nobody else has seen at a racing event before. Kinda boring seeing a million miatas in the RWD class and then a million civics in the FWD class. But if you want to race every weekend then it's the perfect choice! Not to mention it's probably the perfect choice for the slow speed, tight tracks that you've been racing the SX4 on. Chassis balance and having a really quick steering rack is probably the most important rather than overall power.

Yup I hear you. I've enjoyed my Sx4 and all the faces of the folks trying to figure out how that weird looking Suzuki kept making the podium. Unfortunately money is an issue and open diffs and spongy brakes aren't great for track use. I had lots of shortcomings with the SX4 which I just couldn't fix without pouring serious cash at each individual problem.

Wagoneer
June 2nd, 2014, 10:03 PM
Completely understand. I ran into the same issues racing my Volvo 850R. You need DEEP pockets to daily drive and race a car without huge aftermarket support. It gets frustrating at times and really sucks the fun out of it. Sometimes you have to stand back and think, "why am I doing this if it's not fun anymore?" If I had a full pit-crew with unlimited funds to replace my broken axles, bent rods, dropped valves and constantly breaking steering rack, I'd probably still be driving that car. I still have a completely stock 850R to fullfill my 5cyl fix whenever I need it :P and with stock power it doesn't break every 5min.

AdR
June 3rd, 2014, 05:59 AM
The SX4 was pretty reliable. Unfortunately to be able to push any really significant power (upwards of 300whp) that is where I bet the reliability of the drivetrain could become an issue. It handled around 250hp without any issues but you have to start wondering even if you build the engine how much would the transmission and awd clutch pack, axles, clutch, etc would last at those +300hp figures.

I hardly think I'll have reliability issues pushing the Miata to a whopping 130whp lol.

As it stands now. I still have to work on a couple of things but now she drives and runs good. I still need to plastidip the headlights and other mechanical/cosmetic tasks.

Don't the LS swaps utilize most of the stock drivetrain aside from the tranny?

Doesn't matter. There will be no swap, turbo nor anything to this car. The SCCA rules do not permit such modifications and the drivetrain needs to stays practically stock. It's Improved Touring after all.

I don't want another street project for occasional tracktime use. This is to become a competitive addition to my regional door to door IT-S class. I will start with track times and Solo events until I reach the point the car is set and I've perfected my driving technique. :D

Haha, I wasn't saying to do an LS swap, I was merely proving that the drivetrain will have no issues handling that massive 130whp :P

The drivetrain is capable of handling quite a lot of power. The only thing that needs quite a bit of reinforcing for an LS swap is the chassis.

Yesterday was the first shakedown of the car. Everything was smooth and worked great. Just need a few changes to the suspension and more seat time. My priority was verifying reliability over time and since this is my first time on a rwd chassis I kept conservative on my driving line and speed.

Enjoy the pics:

Not that big of an issue. But it is taking me some time to relearn corner entry/exit and trailbraking as it's all quite different than in fwd/awd. Thankfully the oversteery way I set the SX4 really helped on car control. It sure is fun to let the back end loose. :D

can you add wings\spoilets\splitters under the class rules you compete in? or does everything have to be tuned through the suspension?

PS- car looks great and I'd love to get one sideways someday too!! (we have no affordable racing events around here. The nearest track is 50 miles away and you have to pay a $3800 yearly "membership fee" just to get started...)

AdR
June 23rd, 2014, 08:49 PM
Nope, no spoilers, splitters nor anything non OEM. Everything is suspension based. Even the suspension has limits (no external reservoirs, only one bar added, etc).

My two track options are about 70 to 100mi from my house. But then again, I live in an island that's roughly 100miles across. Lol.

PS: $3,800 in membership fees is incredibly expensive. Is it a well known track?

June 23rd, 2014, 10:08 PM
That's a ridiculous fee. Is there an included gentleman's club on site with free lap dances? I think they're clearly cashing in on the porsche GT3 and Lotus crowd.

I have the same problem around here in Canada. We are extremely limited in race tracks, especially ones with open track days. It's been proven again and again and again in countless research that areas with affordable open track days where kids (and adults) can get it out of their systems safely will have FAR less speed related accidents. And it makes perfect sense. You complete a modification on your vehicle and want to see the results. No track you can afford or the lack of one completely leaves you one place.... public streets. 1/4 mile tracks are pretty common, but even those are starting to get extremely expensive due to insurance and upkeep. And not every once is interested in speed in a straight line. 'merica.

You're a lucky man living on an island and having not one but two track options!

AdR
June 23rd, 2014, 10:32 PM
I've actually got three but the third is a small very technical autocrossy track that's less than a mile in length. But the asphalt is very rough and the tight turns destroy tires too quickly for my taste. It is fun though. It's used mainly for suspension testing, Karting events and Drifting events.

SX4rocious
June 23rd, 2014, 10:38 PM
That's a ridiculous fee. Is there an included gentleman's club on site with free lap dances?

And there is a rather fancy-pants club there. It's beautiful inside, but nothing someone like me could ever afford to feel comfortable in. I mean really, what race track needs a granite-tiled shower with a rain-fall showerhead anyway? This place was designed and built for motoGP and Sportscar racing, then turned into a country club. I'm not for sure, but I'm betting you can get a day with the Indy 500 track cheaper.

Out of pure curiosity (and to further fuel my frustration), what's a test-and-tune day cost on the island Adr? is there a membership fee or do you have an entrance fee on race days?

AdR
June 24th, 2014, 04:33 AM
We had one Sunday and the entrance fee was $125 for non members without time scoring and $15 additional if you wanted time scoring with an AMB/My Laps transponder. You can bring your own and they'll support it for free.


The price is lowered by $25 to $100 for club members. The passive club membership (only vocal, no voting rights) for a year is $100 but it includes heavy discounts on Khumo Ecsta XS tires.

If you run door to door racing or want an active membership everything costs more but it's not really that expensive and you get the added benefit of giving your input in growing the sport and voting on the decisions that can impact you or the sport.


But and there's a big one here. The track's asphalt conditions are not the best and are in dire need of maintenance. I'd gladly pay a little more and see better facilities like in Florida.

midnightsx4
June 24th, 2014, 01:50 PM
The only way to get track time in PNW is to join an auto club. There are few open track days. Admission isn't terribly expensive, but those days get booked very quickly. The best place to try open track is The Ridge. http://www.ridgemotorsportspark.com/
Back on the subject now ...
Will there be only Miatas on a race day or any IT class car?


Cheers...

AdR
June 24th, 2014, 02:58 PM
Any IT class car will be there. From ITB, ITA, ITS and ITR run together although different categories.

They also run with the GT classes GT3, GT2, GT1 & GTT all at the same time.

I'm really looking forward to following this thread. I'm a huge fan of multiple class racing, and obviously, I can't get into it myself around here. Guess I shall live vicariously through you then! I'd do a $125 fee a couple times a year, but the $500 for one day is stupid...

AdR
June 30th, 2014, 10:08 PM
After the initial shakedown I found some areas of improvement. Primarily I need a tune badly. Due to the fact that I have a Walbro 255lph pump instead of the oem the AFR at WOT throughout the band is 11.3. Clearly too much for an N/A engine. So I bought lightweight pulley and this little puppy here. It's the oem crank harmonic damper with a 5x racing crank trigger wheel which will permit me to advamce the base timing by about 5 additional degrees from BTDC. I'll be using 93 oct and with the help of the piggy I should be able to get to a very healthy 12.5AFR. I'll be getting my set of lightweight pulleys for the water pump and alternator this week.

I'm also interested in upping the revlimit to about 7800rpms to help on some corners of the track.

Are you thinking of upgrading AFM to increase cfm. I reckon stock 1.8 flow meter is somewhat restrictive in the ball park of 180cfm at 6000 revs. To run over 7000rpm you'd need 200 and up cfm.

I just realized yours is GEN2 miata with MAF. . . Im intrigued to see what you have planned to up the ante in RPM depo.



Cheers. . .

AdR
July 1st, 2014, 04:20 AM
I cannot upgrade the MAF. Improved Touring rules.

The rev limit will be defeted with the use of the Emanage Ultimate fuel/spark over drive system. Then it will be substituted by an ignition cut limiter in the piggyback.

Cutting ignition only at high RPM could cause problems when all that fuel lights off when it cuts back on. Better duct tape the cylinder head on. :)

Cutting ignition only at high RPM could cause problems when all that fuel lights off when it cuts back on. Better duct tape the cylinder head on. :)

Not really, that's what happens when you use an ignition cut like an MSD hard cut or crank a Bee-R ignition cut to make wasteful sparks (fast & furious complex).

This is a soft ignition cut which doesn't hit the wall fast and then cuts fuel a little higher up. You do not want to cut fuel first on a high revving engine due to the fact that it will create a very lean ignition and the engine will knock and pre-ignite. Not a problem in a daily driver as you don't really bang on the rev limiter constantly but when it's a race car that needs to run at that upper range, the possibility of throwing a rod is very high.

Finally took the Miata to one of the Solo events. It behaved rather nicely although I have to adjust the rake and stiffness/pre-load of the front suspension to remove some of the nose dive. It got rather loose during hard braking and got a couple of close calls. When I say close I mean a couple of inches from the wall close :(. I did manage to get a 2nd place on my class and still be contending for the Championship. Win! :D

It's quite a bit slower on the straights (10mph slower) but what it lacks in straight line speed it makes up in cornering and braking.

This is an extremely agile car and has been proven to hang with much faster competitors in tracks with many turns.

This was my first time driving a rwd car on a very technical track on an improper suspension preload and rake and no tuning. I'm only less than a tenth of a second off of my best time on the SX4 @ 12psi with a set suspension.

Just watching the SX4 videos and the miata video back to back you can tell the miata has a lot better turn-in and ultimate corner speeds. Just goes to show how much weight distribution counts on the track.

Don't get me wrong, the SX4 is very fun to toss around and the point and shoot action is great for people with little to moderate experience that don't need the hassle of constantly doing corrections in steering. If it had better weight distribution it would be even better but unfortunately it's nose heavy and understeers like a pig. To get the back to rotate you need to stiffen the rear so much that it's not very driveable on the street so it's hard to make it your double duty track/street car.

The Miata is so well distributed and nimble, not to mention rev happy that I almost forget it's lacking 120hp vs my SX4-t.

Lol. I like the look of the new one (NC) but no so much the other two versions which include mine. But they're so good in the track I'd take one over many other vehicles in this price range.


If I could have any other track car I'd take an Exige Cup or an S2000 as they're the same Miata recipe, light nimble and exceptionally well balanced but have the only ingredient the Miata lacks... Power.

the only Honda I would ever try to build is a S2K. I'd own an Accord or Civic for a DD, but they're everywhere here. I love the factory looks of the S2k, so I wouldn't need to spend a dime on anything but making it fast. And RWD doesn't hurt either!

I agree about the generation differences with the Miata. New is good looking, old is a bit drab... I've never driven one tho, but I have heard driving dynamics make up for mundane looks. They certainly are popular for the track, so apparentl Mazda did something right there!

agreed, but I'll never be able to own one, so I was keeping it limited to cars I can. I also wouldn't mind owning an older 'Teggy sedan. like a '98-ish... I'm a 4 door guy.

With the suspension set-up you currently have on the Miata, can you DD it? I know you don't but are you 3 inches shorter when you get to the store than before you left? I've always wondered that. (I have back issues, so even a couple hours with a true race car equals a couple days in bed...)

Im sure Adr will give you his view on the subject.
However, I'd like to share my experience with semi-race car. Although I didn't have roll-cage in the previous Scion xA, the structre of compact xA was stiff.At the end of its life was set up with triple spring rate coils, Koni Sport dampers at 60-80% (fr-rr) stiff, no front sway bar, TRD rear sway bar. Good trail braking would sent it into controlled oversteer.
And it was all managed with 100 Bhp engine via auto gear box. :thumb:
I loved it. My wife hated it.
Sx4 will have similar set up. I just got side-tracked with this turbo project. :D

It could easily be a daily driver. The springrates aren't like the SX4's which were so hard you'd get spinal compression driving it out od the driveway. This car does need to flex some with the bumps as it already oversteers, the SX4 has to be so tight to get her to rotate that it was no daily drivable.

For a FWD car midnights setup is the correct way to do it. It will create lift-throttle oversteer in a very controlled fashion. That's how I had the SX4 set. Get it as stiff out back and mid-to-soft up front. It will rotate like on rails.

BTW midnight. Out of curiosity. Why automatics? Usually people go for the manuals and even more so on rally cars to be able to control gear position at corner entry/exit.

midnightsx4
August 23rd, 2014, 01:48 PM
Like Sx4, my xA was used by my wife before I got hold of it. I tried to teach her manual gear box. Some people just can't.
At first I was unsure of auto gear box. Then I learned to shift (auto has a delay when downshifting) to manage turns and sweeps. In no way auto comes close to manual gear box in maintaining engine control. However I like that fact that auto gear box eliminates heel-n-toe trickery.

I've got this dream of building a total sleeper project someday. Something that can impress during track days, dominate on autocross days, and still be fun to drive the 36 miles to work (safely of course). i think maybe a miata might be a good starting point. I think an S2K might be perfect the way it is, but most people don't expect much from a Miata even though it's the perfect platform. I see an S2K and already know it's fast. That kinda defeats the purpose of building a sleeper...

I've read many positive reviews about new WRX (not STI). One drawback of new WRX is lack of wagon, otherwise it is grown up Subbi. However if you want an STI, get an EVO X as it by far better performer, all things considered.

I agree, but my SX4 is basically my drive to work car. I occasionally have my family in it, but for the most part, our Kizashi is the one that handles the practical stuff ;)

Once again, it's just a pipe dream, but I envision something like a 2JZ swapped RWD Tercel with minimal exterior modifications, or a Gen 1 Sentra with a SR20DET motor. You know, something simple and not at all ostentatious! :hi:

So I got off my lazy bum and attacked the interior or the Miata. I'm going to a two day event and my wife wanted to ride shotgun but that was impossible without a second seat.

Removed the interior:

Nah, it's just easier to clean and hose off vs a matte or unpainted surface. It gets dusty and dirty and am always having trouble cleaning the interior plus it kinda looked crappy with all the black overspray the previous owner left while painting the rollcage. I wanted to paint it gloss grey but Wal-Mart didn't have grey paint at the time so black it was. :)

In all seriousness, I'm getting a mat but it's thermal protection for my feet. The driver footwell of a Miata gets interestingly hot due to the header placement.

Doesn't dynomat provide thermal protection too? Well I guess it would defeat the purpose of removing the sound deadening since it's also rather heavy tho...

AdR
September 16th, 2014, 08:25 PM
Dynomat is a sound deadening material which has some light thermal insulation but not enough, it's also not resistant to abrasion and given the fact that it will be in direct contact with my feet it wouldn't last long.

I need a thermal insulating material (nomex, nextel or some sort) with a reinforced matting. The unprotected footwells of Miatas can easily melt soles and even in occasions cause skin burns in endurance events. The material of choice is pretty expensive but safety in my mind always comes first.

Since on my last outing I had some heavy nose dives which affected my lap times severely and unbalanced the car during braking. I decided to get an ajustable proportioning valve to fine tune the brake force front to back. Mazda really dialed the rear braking force from factory to be almost non-existant and without abs there isn't much compensation making all the brake force go to the front. Since I didn't want to have to go through the trouble of getting a custom made line to be able to locate the adjustment knob inside the cabin and have never liked the idea of fluids inside the cockpit either I got creative with a remote brake balance bar adjuster and made my own remote proportioning valve setup.

AdR
October 13th, 2014, 05:05 PM
It's the ABS. New cars don't use a proportioning valve rather than the ABS to do the brake distribution. If you disconnect it, you should get equal distribution to all 4 corners (biased only by nominal line pressure and the caliper/disc setup). The proportioning valve will let you dial it down to the best possible bias. But that looses use of ABS and for a daily driver I don't recommend it.

I cannot use splitters and in all honesty I'm still working to set mechanical grip to need any type of aero.

midnightsx4
October 13th, 2014, 05:14 PM
I'm exploring options on how to safely make ABS switchable like on some high end bikes (BMW comes to mind) and integrate valve to +/- rear bias. + rear bias helps rotate car better in loose stuff.

That'd be awesome. There have been lots of times where I've been sliding down a muddy hill with the brake to the floor, ABS going off like crazy and I'm not slowing down. It would be nice to be able to flip a switch and have the ability to lock up the wheels when you want to.

Little update:

I pulled he engine for a refresh. It had good compression and it was running strong but the water cavities were all gunked out due to the previous owner running it in pure un-destilled water for so long and had massive oil leaks through all the main seals.


Let the disassembly games begin. BTW my wife looooves having the car crossed in the garage (sarcasm):

I should have everything back and ready to install in a couple of weeks at the most. Hit some snags when one of the pressure plate bolts shared off. I had to drill and retap the hole again and noticed the bolts were a little skewed. Apparently the PO had overtighened them. I am surprised they lasted this long with how they looked. I'll be getting a new set and a new pilot bearing this week. Hopefully I'll make it to this year's race season.

You make the process look/sound so easy!

I'm currently helping my brother rebuild his B6304S (Volvo NA 6cyl 2.9L - bored it out to over 3.0L with oversized forged pistons) and it's definitely not that easy! Only a person who has personally torn down an engine and rebuilt it from the oil pan up really knows the work and the knowledge that goes into it. But man is it ever worth it when you turn that key and the thing actually starts. Always reminds of that scene from Castaway where Tom Hanks yells, "I MAKE FIRRRRRREEEE!"

And you think those coolant passages are blocked? I'll show you my Suzuki DT20 outboard motor I'm rebuilding right now. I'm surprised any water was actually able to flow through it at all! Why did the OP use straight water? I understand for a race spec car, but coolant has specific detergents to stop calcium build up, so why not at least do a 50/50 mix or something? And it's not like there isn't race spec coolants out there.

I don't know if I make it sound easy but it's really a pain in the behind. You really have to love the art to do it and it takes someone as or more OCD as myself to do it the right way without cutting corners. Many wouldn't even bother with half of the steps I took. I spent countless hours measuring and calculating all the gaps, clearances and roundness of parts just to get the right bearing and ring gaps. Hopefully this will translate into a smoother and reliable engine.

BTW: It's the first time I haven't had to gap piston rings. This Miata engine is so on spec and the rings I bought came all almost exactly the same size. So if you ever want chrome-moly rings on your build Mahnle's are exceptionally well made.



The reason the PO used water is that we live in a tropical climate (no winter) and water actually is a better heat transferring agent than a coolant mix. Also it doesn't make a mess at the track for others (coolant cleanup is a pita). His mistake was using regular tap water. The only water anybody should use in their system is destilled water and I always add water wetter or equivalent additive to provide the rust inhibitors requires to keep the passages clean. Unfortunately, there were a number of mistakes done on this car that I'm now fixing as I keep finding them.



Very nice build! When does your race season start?

Supposedly it starts on March but practice is on February and I'd like to break-in the engine by then. Who knows if I'll make it. If not I'll take it easy and finish up. Better do it slow and the right way than fast and sloppy.

Well small update... So after a whooping 1hr of the build the oil pump was apparently defective and decided to die on me while the car was strapped on the dyno... So it's back to rebuilding the engine and a new crankshaft since it literally ate the sides of where the #1 rod rides on the crank leaving enough sideplay to stick a piece of carton. That's one of the few places you can't really fix on a crankshaft since you need the endplay gap to be a certain amount to retain pressure from being lost through the side. Fun times!

New oil pump on the way with all appropriate gaskets and materials to rebuild take #2. Is it me or do I have an awful bad luck with oil pumps? :(

I've rebuilt several motors in the past and it's the first time Ive had something go wrong. It sucks that it had to be on the one that I've been the most careful and methodical on.

I should have it rebuilt and strapped on the dyno again by the end of the month. Its ironical that the oil pump was an OEM piece and not a chinese knock-off. It would probably be running now if it had been a POS pump. But Murphy is that type of pal that loves this ironical stuff. LOL :D

Pressure just fell instantaneously. When I opened the crankcase I found that the backplate that holds the oil gears was slightly ajar. Apparently the cover either unscrewed itself or just had too much pressure which I highly doubt. I did open it to check clearances and put it back together which could might as well have been my own doing the reason it opened itself up. I guess it didn't like the blue loctite too much?

I finally rebuilt the engine. It was literally a nightmare since my BE oil pump got lost and a lot of issues arose just to get the parts to start the bottom end rebuild on the way. Then when the bottom end was done I verified my head for issues and surprise surprise it was toast (journals scarred beyond repair). Had to buy one that was supposedly a 25k mile unit in perfect working condition and it ended up being the exact opposite so the head was rebuilt with new valve seats, viton seals and the works.


In this process I decided to get the ITB's installed which I had been sourcing and gathering for a while. I'm using 4AGE Silvertop throttle bodies with a Techno Toy Tuning NB Miata adapter. This is much cheaper than buying a Jenvey or Borla system which costs over $1600. I managed to get it done for less than half of that. Still tuning and awaiting a couple of things like the catch can, thermal blanket for the header and the itb velocity stacks (using the 4AGE curved plastic stockers for the time being).

The tuning process has been slow since I had to make a MAF clamp out of basically very raw data (due to lack of logs) since I am using a Greddy Emanage Ultimate piggyback with the stock ECU. This is a slight problem and obviously a standalone is the way to go but the engine rebuild sucked my EMS budget dry. The EMU is working fine, the auto-tune feature is doing the brunt work of things and should finally have it on the dyno next weekend. After everything is done and bolted in I'll start deleting the unnecessary plugs and cleaning the wiring around the engine bay.

Sounds like quite the process. It is coming together very nicely. :thumb: With additional wire cleaning that is going to be a very clean engine bay. I bet you can't wait to have the dyno tune complete and get it back out on the track.

I should be able to clean everything even better when I finally get the standalone as right now I am limited to the stock fugly fuel rail. But for now cleaning up the wiring will be my focus as I am not a fan of exposed wires on the engine bay. It should look much better once the velocity stacks are in place and all the engine bay has gone through a thorough cleanup.

You can't imagine how stoked I am to finally tune and go to the track. My championship hopes have gone down the drain. I already missed three events out of seven. Now I will just concentrate on getting up to speed, get to know the car better and prepare for 2016 since the rules are changing and it will get even more interesting. This is my last year on street tires as next year I'm upping the tire contact patch and running on slicks. [emoji1]

Here's a little video of one of the last passes of the Miata on the dyno tuning session. The results were 136whp @ 7000rpm and 120ft/lb-tq @ 5300rpm with allmost all the powerband relatively flat. A few hp were left on the table on a conservative AFR, the VVT nor exhaust cam timing were modified and this was tuned without the 75mm velocity stacks which are quite larger than the 4AGE oem plastic curved stacks. Needless to say I need a good standalone and an adjustable cam gear.

Look closely at the end when it spits out a nice blue ball of flame. #BecauseRaceCar :hi::cool::cool::cool:

Finally got the velocity stacks from T3, cleaned up the engine bay and did some wire management. Now the looks match the awesomeness ITB's are.

Pretty happy to finally have an outing. 😀

Too bad the tune went out the drain thanks to a bad wire splice the PO did to the oem harness. Managed to only do 3 laps with heavy misfires. 😕

So went back to the dyno to get my Miata fine tuned. Since the last tune I put the velocity stacks and the standalone ecu instead of the piggyback. The results: 10whp/8tq over my previous tune and a much better response. This was achieved in the 28th back to back dyno pull on a very hot enclosed dyno. With the naca duct directed towards the stacks and a better/cooler air stream I should have even more power.

Thanks. Hood wrap is done to cover the hackjob done to fix the crash the hood used to have. Had to add a 3rd latch since I cut the underside structure and this is an aluminum hood (very flimsy). I saw no practical reason to get a new hood just to hack it up to install the naca duct lol.

Got a track day event this Sunday. Can't wait!

Will also try out my new F.A.S.T. Cool Shirt system. I'm finally not going to melt inside the cabin. :cool:

Thanks. I like the gains from 35-45mph's (3500-4200rpm's) where I gained 24ft-lb/tq over my previous tune thanks to the vvt setup. It helps now bog down furing the hairpin section and slow corners.

It was a trackday so there was no timing but I managed to use my 10Hz lap timer to gather a 1:32.83 which is about 1 second faster than my best lap time. The car behaved ok although I need to corner balance it. My front tires were a little bald and the grip was greatly reduced, was on new brake rotors and literally had to get used to the car all over again. My driving was what I would call a big giant mess. Lol. It's basically a new car now and I'd say very capable. Comparing it to my best times before when the car had brand new tires, was properly set and I wasn't overbraking I'd say it can easily go down 2 additional seconds well setup.

Here's the video of one of the runs. You can hear the engine much healthier than before and the sound is very different.

You can compare it to the sound of this video and notice the difference from then to now (same GoPro, same location, same video software, no changes in sound whatsoever):

https://www.youtube.com/watch?v=gADfHwXy2HM

This was the aftermath of the brake lockup you saw on the video. Flat spot anyone?

I will be using these babies soon. I wanted to know the weight of the car which with me on it (I weigh a hefty 210) is 2415lbs wet. Unfortunately everything taken out of the car for racing purposes was added back in the form of the rollcage. So with this and the max whp I end up with a power to weight ratio of about 16.5lb/hp at the wheels which is so-so when compared to others in my class which are on the 12-14lb/hp range.

As for as the F.A.S.T. cool shirt system. It is awesome! I can't believe I didn't get it sooner. I was comfortable all the time and it lasted throughout the event (8:00am-3:30pm) without any refills. If I had used solid ice instead of the ice with holes on the center it would have lasted even longer. This is a must for any serious competitor during a race or a track day where temps get to 100deg F easily.

That track layout looks fun! Great job on dropping your time a full second lower than your previous best. I bet the brake lockup got the adrenaline going. Good thing it happened on a forgiving part of the course.

It is. It's a very technical short track but it's lacking elevation changes (flat as a corpse's pulse). It does equalize bigger hp cars with us power challenged. :D

Happy day for me. Finally got my set of Hankook Z214 225/45 slicks with some nice Advanti Storm S115x9's to put all the rubber to the road. My previous setup was 15x7 Kazera KZ-M's with Toyo R888 205/50 rubber.

Ironically with the larger rubber and wheels I am at 1lb and change under the former setup which was already light. Talk about ultra lightweight.

Apologies for the thread hijack.....I just bought a 246 000km 1991 Miata. Bought it yesterday. I drove the car back home and the clutch started slipping under 60% throttle...I was like, damnit new clutch...I said to myself no problem, the car was cheap..

Today, I drive the car around town for 30 minutes, no slip at all. I launched at 5000 rpm. No slip!! I go on the highway for 20 minutes. 1-2-3-4-5th gear at WOT, NO SLIPPING. The hell is wrong?? Glazing?? Clutch is shot??

AdR

It might be either. Drive it for a longer time and see if the clutch settles. If it stops doing it, it was probably some glazing or that the spring hub of the pressure plate were sticking. If it keeps doing it then you'll need a new clutch. These engines don't produce enough power to have too many clutch issues.
