Ughhhh... Are we talking about street cars, or race cars?

Maybe I'm wrong, but I don't think you are going to make anything with 2.0, 2.2, or 2.5l make 400WHP on 91 octane pump gas, so what are we talking about?

More displacement increases your ability to make more power with lower octane fuel, all other things being equal.

I'm with Mike K. on this one. I'll take a 2.5l over a 2.0, or 2.2 for use with pump gas every day, no matter what the internals. Of course, I'd prefer forged.

P.S. Do we know up to what VIN had forged internals on the US STI? Might be worth thinking about when looking for a used one.
