I have a 1990 240sx with an S14 SR20DET. It had an S15 turbo in it until I blew it on saturday Manji drifting leaving thhe car wash. So I acquired a rebuilt GT28RS for $350. I have no choice but to buy this turbo for that price. I was making 340HP to the wheels at 18 lbs. of boost. I have 550cc injectors, Z32 MAF, Enthalpy tuned ECU, Megan manifold, BLitz LM intercooler, Koyo Radiator and an elctronic boost controller and turbo timer to make it all run smooth. Now my question is how much power can I expect to gain with the new turbo and how many lbs. of boost will I be able to safely run. Also, will my existing modifications do the job to make the power I want or will I need to do some more changes?? Thanks in advance for all the help.
