I have a 85 first gen, and the motor is out of a 89-91 Turbo II, I have put on a large street port on the intake and exhaust, have a full 3" exhaust, and large front mount intercooler. Everything is ready for a bigger turbo once I get a Haltech, but my question is this- I want a To4s turbocharger, but what A/R numbers would be best for good street response, and very occasional drag racing, mainly road course and autox? I would like between 350-380rwhp, and boost to hit strong at about 4k rpm, with no more than 15psi. Oh yeah, I may be using a 93 upper intake manifold and throttle body if that makes any difference. Thanks for any help ahead of time.
