Mods at the time:

GT40R / 1.06
11PSI, spike to 13PSI

Stinger 4424, stock 1JZ coils
880cc top feed (at the time single feed/return)
Greddy 3 row
fully built 1JZ head 1mm OS valves, aggressive port/polish, 272 custom cam setup 9.3/10.3mm lifts, ferrea dual springs, etc.
stock 2JZ-GE block and stock 1JZ headgasket. 180psi compression cold +/- 3psi.
~9.2:1 comp ratio
Single Walbro pump. I was close enough to my goal of 450rwhp. I was on 2 inch piping off the turbo, and was not about to try and get anywhere close to max. This was just a baseline on wastegate only, basically.


I made another pull of 440rwhp and 361ft. lbs, but I can't find it anywhere and thinks the tuner forgot to email it to me. :: angry :: Anyway this gives you an idea of the motor/turbo at low boost......

I talked about this setup and power for a while, but I never put down a dyno sheet. Just thought I would post a thread and do that for anyone interested in seeing another GT40R sheet for comparison and what not...

I never maxed the GT40R turbo out. I decided to go ahead and put the VRP 74mm turbo on the car. The whole triple ball bearing thing with a S374 compressor with tips and .84 A/R.

I have upgraded my pipes to 2.5 inch and installed an A1000 pump/dual feed. Methanol injection has been modified to three M5 nozzles, and I will be running 93 octane. I am ready for the dyno next weekend.
