Hello all. I'm very new to this forum and to owning a civic in general, and have recently bought a 2003 Civic Si with an Acura K20a3 motor and transmission swap, pistons bored over .10, cammed but I'm not sure whether it's a factory Acura cam or aftermarket, full Greddy exhaust and RDX 410 injectors from what I've seen so far. I am looking to build this platform to around 300-350 hp but have no idea what the best and most affordable way to do this is, whether I should use a turbo or supercharger etc. I come from owning nothing but Subaru's so my experience with Honda's isn't exactly expert level and I figured instead of trying to use my Subaru knowledge I would see what you guys and gals think. This car won't be for racing or any competition, just a fun daily driver with a bit of power. Any hints or pointers to make this ugly bean fly would be greatly appreciated, thanks!

I am aware using a turbo will do that. I'll just assume everyone else will be as unhelpful as you

So what else would you like to know? You have a great starting point and there is a crap ton of information about turbocharging the K20 on this site and many others.

Your post was a little open ended so that might happen.
