Bolt-ons?????

I have a 2001 sentra SE 2.0. I'm not really new into the aftermarket companies, but im lookin @ what will work best with my application. I dont have any plans on getting turbo or NOS, however, i am planning on raising the compression ratio with pistons. I'm lookin @ tryin to get my engine puttin the most out from bolt-ons. I would like to gain power in the mid range RPMs (4-7k). What company(s) make the best intake power. I see AEM is like $240, but Injen is like $180. BTW, im in an AUTO. I also seem to not be able to find any throttle bodies that are bored out or anything. could u guys give me some links and company names. Ive also heard about cut-out exhaust. I was wondering if that was any good either. thanks. O and what would i run from all bolt-ons. thanks.

Well, a lot of people will disagree with me, but I believe firmly in HKS's products. If it were my car, I'd get an HKS intake and exhaust, some JWT cams with a JWT ECU, and UR pullies. As far as high-compression internals, look at www.jgycustoms.com selection. They are the masters of the FWD SR20.

get z32 300zx non-turbo pistons. overbore your cylinders 1mm to 87mm and the pistons will raise your compression to 11.0:1. plenty high but still driveable on pump gas

try these guys. this will help your intake side HP besides the CAI. hotshots or AEM for me.
