edelbrock,drag,revhard,greddy....all make kits i think. Honestly.. the RSX type s is 220 to the crank i think.. that makes it like 200 to the wheels.. with Catback, headers, Intake and some other minor bolt ons you will be pushing like 240 horsies and prob 220 to the wheels. With a turbo you will make aboutt he same but your gas mileage will be about half of what you will have with the k20. and it would also look better to have the k20 show wise, just IMO.
