Woot for SOHC Single Turbo - Page 3 - 3000GT/Stealth International Message Center

In 97 the compression went from 10:1 to 8.9:1 on the sohc. Still the most boost ive heard that is safe is about 8 psi. I dont see why you shouldnt be able to get more with proper tuning. As for the larger fuel injectors, a vr4 fuel pump would probably be a smart bet to keep them fed right.

cool, so the book I have is right, just not updated for 97+

There is so much wrong information its ridiculous. The SOHC 3/s was ALWAYS 8.9:1 and ALWAYS has 210cc injectors.

Good luck with the project. Just hope your diff handles it. I killed two last year on NA SOHC power.

Stealthee · 04-24-2008, 08:40 PM

Probly sunminds 98 SOHC. I think he hit 220 at the wheels.

yeah im pretty sure it is sunminds. there isnt a nut or bolt in his sohc that is stock lol. ive heard other members on the board talk about a scd sohc putting down 260 ish whp. but i havent heard that claim in a long time and they didnt post dyno sheets to prove it

kendo · 04-25-2008, 06:11 AM

supposedly the setup ive got now was running 254 at the wheels before he crashed the car and sold it to me. we'll see in a few weeks when my new turbo gets in.

also wanted to say when i started doin research for fuel control one of the s/c sohc guys told me the SAFC2 sucked with the sohc, he actually blew an engine with it. Hes running a MAP ecu now and he said it works great. i also went with MAP, it wasnt even hard to get everything running again with the 360s and ive never tuned anything before this. Plus i dont even have my MAS hooked up anymore which opens up a lot of room for the turbo plus i have less intake restriction. it just takes a lil longer to get it tuned because of all the cells and you need a laptop.
