This list is in order of install, so you can slowly add more power as you feel that you want it:
Before you do ANYTHING put Royal Purple Transmission fluid in it...this will protect our weak little synchro mesh gears prolonging the life of your tranny.
1. throw the K&N in the trash and get an Injen CAI with aqua sheild
2. a good quality RACE header (not shorty) Buddy Club, if you have the $, if not then Comptech or Strup. I would recommend the strup over comptech cheaper, similar quality, and better design.
3. A good exhaust. I have had 3 on my car before I made 1 myself. Good: 1. comptech, 2. HKS anything 2.5"
Bad: Megan (great for S/C (supercharged) apps. but it kills untuned N/A cars) it's a 2.75" and it doesn't provide ANY backpressure.It sounds great but it's LOUD!!!
3. K-Pro is AMAZING!!! it allows you to tune your A/f ratios and many other things such as fuel point's and so on, so you can get the max out of your motor and keep it running properly.
4. RBC Intake Mani. from the K24 motors. even when i wasn't boosted it made a HUGE difference in power for my car it made a 21hp difference after tuning.
6. ESMM (Energy Suspension Motor Mount) Inserts. make the ride a little rough but you have no more wheel hop that RSX'S are so bad about.
5. LSD(Limited Slip Differential) this distributes power evenly between both wheels, forever banishing the "one-wheeler-peeler". spend the $ on a Quaife , no OBX(ebay) crap unless you can rebuild it yourself like I did. POOR QUALITY like you wouldn't believe. you don't need this to go fast but it is FUN!!!!
That should get you going for now. Find these parts
