yea i am sohc i have 550 injectors gt35 equivlent turbo, not a name brand but generic brand turbo. 16psi is what i normally push meth injection pos ebay intercooler, hks ssqv blow off, i was told the car has all forged internals they guy i bought the car from bought the car built with a supercharger and then put a turbo on it, now i am in the process of getting the turbo setup installed right cause he did everything half ass, i have a crappy obx turbo header not sure what i could put on the car cause i have not looked. i think i am having a heating issues to cause my turbo will glow cherry red after i get on it in a 1/4 mile pull, i am not sure what that is all about. This is my first turboed car so i am just trying to get info on the car and about turbos, i have learned alot since i have had the car but i still need to tie up a few loose end on the car.
