I'm on a quest for ultimate street prowess!!! Just kidding. This is for my own personal enjoyment, and embarrassing Corvettes, maybe an autocross or two. It's my daily driver, but I have a backup car for when things break. I'm retaining A/C function, no power steering. Now on the to good stuff.
The guinea pig will be my 92 Miata, with 140k miles on it. It's had a Greddy kit on it for over 2 years now, estimated at 220 - 240whp at 15 psi. It could be much less, but it was enough to break 2nd gear on my 5 speed. I've been fighting an oil leak ever since I tapped the oil pan, removed the engine and dropped the front subframe multiple times attempting to fix it. Finally I said forget it and decided to build a motor. All of a sudden, a 2 liter fell into my lap.
My end goal is 350whp. I've ridden in a 300whp Miata with an SC61 before, so I have an idea of what it would be like.
Turbo of choice - GT2871r, .86 A/R on the turbine side. I will be porting the wastegate to avoid boost creep issues. If you know anybody with a good used one, I am very interested in buying it.
What I have:
-Built 2.0 stroker motor, previously made 474whp. 9.0:1 CR. Stock 99 head, 95 block (Thanks to Rharris19 for this one
-750cc Deustchwerks fuel injectors
-M-tuned fuel rail, with dual JIC braided SS feed lines (Bling Bling!)
-M-tuned fuel pressure regulator
-Walbro 190HP fuel pump
-Braineack MS, parallel install MSI
-1.6 ACT XT with a street disc
-7lb Fidanza flywheel
-Forge Motorsport BOV
-Homebrew coolant reroute with a Moss spacer
-Enthuzacar 3" exhaust, with cat
-Begi S4 Manifold and Separated gasses DP
-KYB AGX's with stock springs, prototype FCM Tophats, and 36mm bumpstops
-Energy suspension bushing set, yet to be installed.
-205/??/R15 Toyo T1Rs on Konig Heliums
Still to purchase:
-Oil and water lines, ARTech's stuff looks ****. I'll go with his stuff most likely
-Intercooler. CXracing 29x9x3 overall dim, the same one Levnubhin has
-Intercooler pipes. CXracing kit will be the most likely. I don't have a welder.
-Oil Temp guage
-Walbro 255 fuel pump
-Better clutch, most likely 1.8 ACT XT with street disc
-Flywheel to go along with the clutch
-Begi Intake Manifold
-Better suspension setup
-Torsen may blow up, I'll avoid hard launches on drag radials until I get an RX-7 clutch-type LSD
-Can't pass emissions with these injectors, maybe upgrade to MSII for increased resolution, or swap in smaller ones to pass
-Will the S4 tubular manifold hold up to heat cycles at this power level?
-I'll fail at life and everything will explode
The new motor is going in this weekend without the turbo. It'll be cool to increase my displacement by more than half a liter.
I'll be simultaneously tuning for emissions and breaking in the motor, with an expired inspection sticker.
Sorry, no pictures, yet. I'm at work, but don't worry, I'll start showering you with them soon enough.
Am I missing anything? Let me know what you think.
