Either way, yes, it is that simple. Raising horsepower in a turbocharged vehicle is typically not that difficult. The Mkiv Supra Turbo (TT) makes it even easier since almost all of its components are over-spec'd.

Not sure what you mean about a methanol injection concern. Alcohol / water injection is the only practical way to run high horsepower with a relatively small displacement engine (3L) and pump gas. It's great to want everything and then "prefer" to get it all for nothing but unfortunately cars (and life) just don't work that way. The old saying goes: You gotta pay to play, baby!

So, in general* it's one of the following options if you stick with the oem ecu: 1) race fuel at $10-$30/gallon, or 2) methanol injection, 3) ~30% Toluene+MMO ...or be 4) be happy with about 350rwhp max. With an aftermarket ecu you can squeeze a bit more out by playing with the timing curve (be careful!).

* Caveat/disclaimer: There always is one, isn't there? It is possible (but not practical) to get more rwhp on pump gas with a huge turbo. The problems are that 1) the big turbo won't spool till about 6k rpms, and 2) you'll still need to limit boost to about 16psi. Since huge turbos are designed to be efficient at 35psi+, you get the worst of both worlds - terrible turbo lag together with running a huge turbo far below it's ideal boost level. This is such a goofy corner-case that it's barely worth mentioning...I only included it here for completeness of response.

ok, so it is simple to get the 500hp out of the 2jzgte, but how much can i squeeze out of it without running the alcohol injection? i know i would need to keep it under 16psi before having to run special feul.. so with maybe98? octane pump feul, how much power can i get?

also i just want some pointers on difference between hp, and rwhp. i know that rwhp stands for rear-wheel-horse-power, but i just want to know the main differences. thanks.
