Also, I think that with equal drivers a corvette should beat an Sti at solo trials, so I don't think they should be in the same class. Watch Lucas this w/e, and we will know for sure.
So basically, if we consider the "4 valve, twin cam, VVT" multiplier basically a "do you have an 'advanced' valvetrain" modifier and only apply it once, I think we're right where you'd like to be.

Let's try some examples:

Chevy 350 based Corvette
5.7L (base)
= 5.7L -> TT-2

Stock WRX:
2.0L (base)
* 1.50 (stock turbo)
* 1.25 (4 valve, DOHC)
= 3.75L -> TT-4

Stock STi:
2.5L (base)
* 1.50 (stock turbo)
* 1.25 (4 valve, DOHC, AVCS)
= 4.69L -> TT-3

Dean's car:
2.0L (base)
* 1.75 (modified boost on stock turbo)
* 1.25 (4 valve, DOHC)
= 4.38L -> TT-3

sperry's car:
2.5L (base)
* 1.75 (other turbo)
* 1.25 (4 valve, DOHC)
= 5.47L -> TT-3 (don't count swap)
* 1.50 (engine swap)
= 8.20 -> TT-1 (count swap)

MikeK & MattR's cars:
2.5L (base)
* 1.75 (modified boost on stock turbo)
* 1.25 (4 valve, DOHC, AVCS)
= 5.47L -> TT-3

That's it... I'm sold! That really seems to place the cars in classes relative to real-world results. As far as I'm concerned TT-3 should be the Subaru class. Those Vette owners should consider themselves lucky!
