First off yea chill out noobs. Second You have a 7th gen civic 01-04, not the best of civics. The swappable motor for our cars in the Acura Type S engine k20. Not the b18 which will have to have custom mounts, which will give you sh*t horses compared to the k series. But this will cost you a heafty penny. As for cheaper upgrades that will make your car sound better are the intake, headers, exhaust, high flow cat, cam gear, regring cam. These wont make your car to much faster but it will help out and wont break your wallet. As for more performance you can throw a turbo on there. There arent many comapny producing 7th gen turbos yet, but they will get you around the 180-190whp with booting at 8psi. This will run you 3k for the set up. My suggestion is go for suspension first. Throw some spring and shocks on the car, sway bars, tie bars this will make you car much more enjoyable to drive. The best web site to look around and read about the 7th gen civs would be 7thgencivic.com.
