Thanks a lot for your inputs!
With the oem headgasket, you can probably squeeze 450rwhp out of it before needing to do some work. A much thicker headgasket might allow you to get to (my guess) about 550rwhp or so. Like Sonyps307 said, the higher compression pistons are the primary issue with going much beyond that point.

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.
