Based on some quick research, I'd estimate that setup would be good for about 680rwhp at mid-boost levels (mid, for an mkiv is 24psi-ish) on race fuel (of course), with the oem cams, through a 6spd. If you upgrade the cams to 264s or 272s, and run high boost (32psi+) with very high octane race fuel you'd probably get close to 800rwhp through a 6spd.

As far as response, you won't see much useable boost below 4000rpms.

Of course, these estimates all assume your engine is in good shape.

FYI: Here are a few of the links I used for my estimates:

Displacement is no replacement for boost.
Life begins at 30psi.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
