On its own, nothing at all. However, it removes restrictions in the exhaust, which allows your turbos to boost higher. As you probably know, you can only boost higher if you do other modifications, like the clamp mod or a boost controller, that allows you to raise boost. That increased boost level, provides quite a bit more power (I'd estimate up to 50rwhp more, at max boost). Without a downpipe, you'll probably be limited to less than 350rwhp.

Yes, that's a pretty common upgrade path.

No. In fact, methanol is 100% for sure NOT unstable. It's just wood alcohol for goodness sakes!!! Where on earth did you hear that? Maybe they were thinking of nitromethane (or nitrous oxide, ...or trinitrotoluene? ) and not methanol.

Methanol (or any alcohol) is a bit corrosive though (especially to aluminum)...so if you install a meth kit and then boost a lot, it's best to drive your car around for a couple of minutes afterwards to flush all of the meth out of your intake system.

I can probably get you some good recommendations. Please post here or PM me after you've purchased your Supra and you're ready to get your upgrades installed, and I'll track down good shop(s) in your area.

Lastly, please note that there's a lot of other great information on the links posted in this thread:

...many of the questions you asked above are addressed in more detail at those links.

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.
