TWM 52 throttle bodies, K-Pro reprogrammed OEM ECU, Burns stainless 4-1 header, those items are some of the items I recommend. If you planning doing something more simple, for instance, my friend just added headers, intake, and tuned the car with hondata K-Pro and was able to run a quarter mile in his RSX-S 13.7 I still can't believe it but wish I had a K swap. Have fun building your car the way you want to regardless of what anyone else thinks. Good luck = )
