GTM Stage 2 Twin Turbo Kit

I've been around the forum for a while now, and gotten a lot of help and ideas for my car from everyone, but haven't really posted many things. So thought it was time to post an update.

After installing pretty much every bolt on offered for the coupe i decided i still wanted more power. After long nights of research and back and forth calls with Specialty Z in SoCal i decided to pull the trigger and go with BOOST!! So here is an over view of everything.

07 G35 Coupe:

Engine Mods Before FI

Injen Cold Air Intake
Motordyne MREV 2
Motordyne 1/2 in. Spacer
DC Sport Headers
Kinetix Straight Pipe
HKS Hi-Power Exhaust
Unorthodox Pulleys
Osiris Up-Rev

Car made 273 RWHP and 260 Torque on a Dyno Jet @ Specialty Z

Added Mods:

GTM Stage 2 Twin Turbo Kit which consisted of
(2) Garrett GT2860RS Turbos with .86 turbine housings
Angle Mounted FMIC
Cast Manifolds
Internal Wastegates
TIAL BOV
Custom 2.5'' Down Pipes from GTM Motorsports
Walbro 255 fuel pump
DW 600cc fuel injectors
GTM 25 Row Oil Cooler

Since the car still has stock internals the guys at Specialty Z didn't want to push the engine to much, so its running on 4-6 psi through out the powerband.
Car made 392 RWHP and 344 Torque on 4-6 psi. For now i'm happy with the end result but in a couple months i will start building the engine and pushing out a lot more boost out of that stage 2 kit.

I wish I could go twin turbo.. but I really can't justify spending ~$20k to make the car drive faster when I don't track it. But props to you for doing it. Must be fun driving

I feel the same way, I would rather just buy a different car.. But owning a TT beast would be quite nice.

I know I'm a little late to the thread but I have a question. Are using a MAF or MAP based setup? I thought that it was inefficient to use blow off valves if you were MAF based.
