I'm not sure if it's the only difference, but would it be worth it to swap in more aggressive cams in my 04 SI, or would the $$$ be better spent just swapping in the whole RSX-S engine? It bolts right in, plus 6-speed!!!</P>

in the long run i would think the k20 from the rsx would be a better choice. but if hp-$ is main concern then there are other options such as turbos.

True, but drivability would be the main issue with that. Being it's my commuter car, too, a turbo would be a bitch in traffic...

if you ptu a turn\bo on it get a turbo timer or whatevr they are called then you could turn your boost down and then it wouldn't be so bad in traffic

electronic boost controler, you can adjust boost from the wastegate pre-set and up. but actually a turbo isnt bad in traffic. it wont really boost untill you get on it, also it doesnt boost low enough to act like a supercharger. you could always go with nitrous<IMG src=smileys/smiley2.gif border="0">

what is it with you guts and nitrous. not being mean just wondering. i mean i know its a cheap way to go but if you mess up there goes your motor

yeah nitrous is by far the worst to tune and use if you dont understand it. but its by far the most powerfull as far as money-hp/tq. but then again nitrous is only used on the track so as compared to a turbo or s/c that is used everyday it wears about the same in a set period of time.

Ahh I hate nitrous ... I think its the easy way out, but that's just my opinion. Anyone can slap a bottle in their car and call it a day.I think you shoudl definitly go with the KA motor. The RSX is 6 speed besides its one of the hottest swaps out there now. Also Theyre rare as hell now. I think its WELL worth ur money .. and later u can make it turbo<IMG src=smileys/smiley2.gif border="0">

Dont try to build the stock motor, you will never be happy with the end result. Get the RSX-S because you will have a better base to start with, well worth the cash.

yeah, nitrous is the cheapest bang for buck, but it will kill your motor.
