exactly...basically, i was referring to what rotarygod said about the stock intake...i'm wondering if we've hit the ceiling or come close on how much air can go through the intake ports cuz of their size.

Nope. You forgot about employing a bridge, or even a peripheral port. Just because the stock ports are as big as they are doesn't mean there isn't any room for improvement.

lets keep in mind as well, that the 4 port (the motor on USDM A/T cars) motor is available with a 5 speed manual in some markets (JDM is one of them I believe, I know UK/EU is). some people say the 4 port is better for boost. it all has nothing to do with an AT itself.
