We just finished up Phase II of Tom's G35 Coupe. It was the first G/Z with the SP Twin Turbo kit and ProEFI standalone.

He went from:
-Precision SC54 (54mm inducers) twin turbos
-SP Stage 1 Built Shortblock
-SP Big Fuel System (1000cc injectors)
-ProEFI 48 Standalone ECU
-Stock Cams
-Southbend Full face clutch

To the following:
-Precision SC60 (60mm inducers) twin turbos
-1200cc injectors
-Brian Crower Stage 3 272 cams
-Southbend Stage 5 clutch/flywheel

Here's the excerpt that Tom posted on my350z.com and ChicagoZ.com:

So my setup was becoming obsolete....and we know how steep that slope is for changes....so it was my turn.

Well last year the clutch finally gave up on me so it was time to change it. That meant pulling motor (do to location of turbos, can't drop trans with motor in car.....ugh).

So since motor is out and turbos are off, might as well make changes right?

So the major changes are (And this could be the perfect street setup BTW):

-Precision Journal bearing 6031B turbos (same exhaust side as before modified intake side. Couldn't upgrade same turbos to billets due to different housings so this was best alternative to purchasing completely new turbos).
-BC Stage 3 (272) cams, and BC springs/retainers.
-Fluid Dampener (cracked a 2nd stock harmonic balancer)
-DXD Southbend Stage 5 Extreem 6puck clutch
-DXD Southbend Billet Flywheel
-Precision 1200cc injectors (up from 1000's...planning E85 here in the future).
-And exhaust was coated

Results:
edge of pump gas (19psi) made 655rwhp
22psi (110 octane) 706rwhp
Couldn't go above 22psi for now due to crankcase pressure. I still don't have a catch can which is requried at this point. So after that goes on the boost goes up.
For reference, on the old setup 25psi was 690rwhp, and 30psi was 769.

This one looks on track for 900rwhp on same 30psi as before!!!!

On street, still feels stock. This clutch is lighter/smoother than old. And it pulls like a raped ape, even on pump gas.

I'll get vids as soon as I can.

Here are the dyno's
They weren't picking up Tach signal so its just mph off dyno. I calculated rpm off that...not sure how close it is as larry showed me the rev limit is 7400rpm...so dunno whats up with that. When we turn boost up we'll get tach signal and TQ.

22psi

19psi

15psi

11psi vs. 22psi

old and new - This is the old setup with open downpipes vs the new setup
through the muffler both at 11psi.

god...so awesome...but these guys have to spending a frigging fortune to get these numbers (not saying SP is pricey, just saying the VQ is not).

Nice! In the vid It says 655PSI instead of WHP, not sure if you care or not just thought i would let you know! You guys up there do some good work, that car looks pretty wicked.

It definitely doesn't come free but they sure turn out nice!

Thank for posting it up Reid....

Yea Ryan is a trouble maker with me at the gov't run places!!!!!!!

Beauty of this car is it still drives like stock. As a matter of fact, if you can keep the RPM's down you'll never know its modified.

Too bad the stock VQ motor won't take too much, but SP has shown with the right pieces, installed properly, it'll shine with the big boys out there.
