Just to clarify things a bit on swaps....just about any motor can be fast if you have enough money to invest. Im running a stock civic HX motor and if anyone knows about them they are complete crap, but im aiming for 15.8 on a stock tuned motor. A friend has an all motor B16 pushing into 12's...
My point is that if you have enough money and the right tuning skills, any motor is a possibility whether its a turbo LS or an all motor SOHC.
