Hmmm interesting ideas....
you've all brought up. Engine strength does have a LOT to do with how much potential it has, especially when you're talking about forced induction. However who's to say the 4.5 won't be just as strong as the 3.5? They're made by the same companie. It doesen't really matter though anyway as I'm sure once you start getting really serious about making horse power with either of those engines, you'll start looking into stronger engine components than what the stock car gives you.
I know the eight cylinder will never beat the sixes in Japan though, you guys were right. I forgot to consider the fact that there will be infinately more parts made available by a plethora of companies for the 3.5 V6 than we will ever see in america for the eight cylinder engine. In fact I'm betting most people just swap that eight for a 350 Z motor and go from there, if they have the cash to do that that is. Still I think you could make one those eights pretty quick, but you might be hard pressed to find the parts to do it with.
Anyway yeah, I'm done now.
