I have an 89 supra turbo and I wanted to get a hp between 400-500hp or 400-500rwhp? what do I need in order to get that. Right now I am in the process of rebuilding my engine.

Forged internals, 550c or better injectors, upgraded CT26 or other turbo, 3" or larger exhaust, port your intake and exhaust manifolds, probably will want a standalone engine management system, wideband, etc. Depending on which tranny you've currently got and it's condition, plan on either replacing or rebuilding with new components.

$$$$, in other words.

thanks for the tip.
