dunno if this is a pertinent question but I always wondered why the f20c's and evo 4g63's made so much power from factory, does it have to do with head flow as Ive been assuming? I know STOCK ENGINE (this means head as well), s2000s are putting down over 500 WHP, while EVO's are putting down over 300 wheel which puts em at close to 400 at the engine with stock turbos. Ive always thought SR's were a bit lackluster, at least in BPU form
