After many years of playing the turbo BP game, and messing with many different setups and megasquirts...here is my long awaited build thread.
This is my car. I could go on and on about how many different turbos I had bolted to it, and how many different versions of megasquirt and blah blah blah, but I won't. I'll just explain what it is at it sits.
1999 Miata, internally stock 1.8 with 165,000 miles. Modified FM manifold (as seen here EWG on cast FM manifold?
), with custom built SR20 T25 machined to accept a 60mm wheel (journal bearing 2560) external wastegated setup with Tial MV-S 38mm water cooled wastegate with custom braided line setup. Modified FM downpipe, custom turbine outlet with V band flange connection to FM downpipe. 2 1/2" midpipe with no cat's or resonators. Racing beat dual outlet muffler. Hard dog Xtreme roll bar with hard dog door bars. Rev build MS3 PNP, with Innovate LC-2. Konig 15X8 +25 Flatout's in bronze with yokohama 205/50's. Flyin Miata springs w/ dead coils cut to set proper ride height on Bilstein HD's, FM sway bars.
There is a lot I'm missing out on listing, but you get the gyst.
I will be parting out anything I own that is Miata engine related/ megasquirt/ turbo/ etc.
I bought this car for $2500 last Tuesday. It's an 03 RSX Type S with like 212,000 on it. Dude rear ended a box truck, wanted to fix it, but needed wheels right now, so to craigslist it went.
The car runs and drives actually pretty well. The radiator support is jacked, and the hood and passengers fender, but otherwise it's not bad. I'm going to part the whole car, and use the engine/ harness/ ECU for my Kmiata swap. Best part is, it's an 03...which uses a K20A2 engine. However, the guy told me that that's not the original engine...and provided me with this receipt:
Which was for a K20Z1 (05-06 rs type-S 210hp). So I have a perfectly good running donor car with a K20Z1 in it. Lucky me.
Miata plans are to sell out a garage bay of spare engines and parts, and put the Z1 in the miata. I want to use a Skunk 2 intake and a 70mm throttle body, K Pro V4...Unsure about my exhaust setup though...but I expect to put down about 230whp. I just want to use this car as a dependable work commuter that's easily capable of laying down low 13's in the 1/4.
This thread will get updated very slowly...but after being a member since 2007, it feels good to finally post the start of a build thread.
Thanks everyone for your support and inspiration I've received over the years from members like TurboTim, Braineack, WestfieldMX5, Reverant, 18psi...there's a lot more I missed.
To be continued....
