150 FWHP - Toyota Yaris Forums

Alright, I hate asking questions that were probably asked dozens of times, but I come into the Yarisworld fresh out of ownership of a Mk. 3 Supra... the 7M-GTE engine's headgasket starts leaking at the mere mention of adding boost... what kind of internal mods need to be done? Is the stock HG potent enough? How does VVT-i sync with forced induction? Do I need to run a completely aftermarket ECU? How about the exhaust system... probably need to open it up to at least 2.5", right?

Sorry for being such a n00b.
