Bryce does the VVTeez
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
-6 speed
-1.6 ACT XT with a street disc
-7lb Fidanza flywheel
-3.909 Torsen
-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:
Immediate:
-Turbo
-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.
-Roll Bar
-Oil Temp guage
Eventually:
-Walbro 255 fuel pump
-Better clutch, most likely 1.8 ACT XT with street disc
-Flywheel to go along with the clutch
-Water injection
-Begi Intake Manifold
-Better suspension setup
-Paint Job
Worries:
-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.

I have an extra racing beat lightwight fly wheel if your interested. It does need a new friction plate (Racing Beat sales that part for around $80)
I'm also going to be in Houston this following weekend for the 24 Hrs. of LeMons (MSR-Houston) so I could deliver it so there would be no cost for shipping

Miatamike: Sending you a PM.
Thanks for the comments, it looks like I did my research well so far.

Moss thermostat spacer came in today. Looks like I'll have to get it machined to fit the thermostat, along with drilling and tapping it for the CLT sensor and heater line.
Here's the car as it sits, with no coolant or intercooler pipes. Notice the horrendous oily mess on the concrete. It goes all up and down the driveway.
The motor, with Magnecor plug wires to keep stuff out of the cylinders.
More to come later!

Made some progress yesterday. The old 1.6 motor is out.
Squeezing into the gated area. It's nice to have a small car.
Before I started, minus the hood.
And here's to make it seem like a very quick engine removal. VOILA, it's already out!
Weight reduction, damn that's a dirty engine bay. I'll be painting under the master brake reservoir and cleaning EVERYTHING... Again.
Side by side shot of new and old. I measured the 1.8 to be just over an inch longer.
Pretty dead set. I toyed with the idea of running a GT3271, which is a little more capable, journal bearing, T3-flanged, and HALF the price, but since I already have a manifold and downpipe that I got for a good deal, I'll stick with the T2 flange and enjoy better spool.
