,a k20a3 boosted to 10psi with proper tune up gives 300 plus hp at the wheels rather than a d16 boosted to 16psi which gives 260-280 hp
That really doenst sound that good when you look at the fact the cost of swapping a K20A3 is more than buying a D16, getting new internals and boosting to 16psi.
Oh and ...
performance engines are a good base to start with for serious performance later
With THAT statment said, you do know that you didnt get a performance engine yourself?? Dont you ??
Your engine, the K20A3 uses VTEC mainly to get you more economy. Jus like SOHC VTEC-E ... read up on the internet if you dont believe me. They dont lie ... also think logically ... a 2.0L 155hp DOHC i-VTEC ??? ... Im guessing the lack of performance is pretty obvious considering it makes almost equal power to a 1.6L DOHC VTEC, and 50hp less than its performance counter part, the K20A2
And before you come saying the Z6 is for economy too ... although the D is a SOHC, a D16Z6s VTEC is setup for performance gains, not economy gains (that'd be the VTEC-E ones job).
