I just bought an 88' supra turbo, manual transmission and BONE STOCK EVERYTHING! I want to know if you boost the turbo to 10 or 12 psi, would it kill my engine? Also, would I need to buy a bigger intercooler, get an intake and upgrade my exhaust? If not, what other parts should I buy? I tested out my turbo and it boosted around 6-7 psi. Is that good? Is that how it's supposed to be boosting?

hey :)
welcome to the forum

6-7psi is good for stock and worn engine ;)
to boost 10-12 psi all you need is a boost controller and you should be fine... just make sure you engine is well looked after and not due to blow it's head gasket anytime soon hehe

i have made this thread in FAQ that you might want to read to save me writing it all again :P

lemme know if you need any further information etc and i'd be happy to help :)

Thanks! I was scared that if I was to buy a boost control and set it to boost around 10-12 psi, it might blow my engine. (Everything is stock) How do you know so much about this car? I wanna learn more!

you should be fine on 10psi.. you are probably better to keep it at 10psi so on cold nights etc you can still boost and not hit fuel cut

well... i just learnt from alot of experience that's all
stick around here and you'll learn lots of stuff bout the car :)

=) Thanks! Now, I probably need to buy a boost control and an boost control guage. I was getting getting scared that my car might not be able to handle 10 Psi.

drive safe, but have fun
