i was woundering i have a stock turbo off of an mr2 thats some were around 6psi. would that be alright to put on my stock st185 gts. with a 5sfe and then just install all the oil lines. would that work and if it would what would i need to run it properly.
Yes, it has been done many many times
The manifold and CT26 turbo from 2nd 3sgte will bolt up.
You will need few other things.
Take a look at Manny post on 6gc about 5sfte.
By the way, "ST185" is designated to alltrac.
Your gts is ST184.
