What is the spec of the pump gas where you live? A BPU Mkiv TT won't do more than about 350rwhp on pump gas. Have you considered meth injection?

NO. Pick one - faster spooling or more hp. You can't have both. It's simple physics - a bigger, heavier turbine+compressor wheels take more energy to spool up. Can I eat more, exercise less and lose weight? Silly question, right? Yours is just as silly. Sorry just being honest. Newer technology turbos make a small % difference, but the general answer to your question is still pretty much a flat NO.

No, but all that stuff will help you to make more power with race fuel (or meth injection) and higher boost levels.

Lag is easy to deal with if you have a 6spd - just downshift! With an auto, it's a bit tougher - you need a high-stall torque converter. Either way, lag is overrated. Get a bigger single turbo and you won't regret it.

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.
