if i'm not mistaken a friend of mine said that a lightweight flywheel will help with low end power, as well as getting some mild cams, and as someone else said 4-2-1. i got a 90 crx si with the stock d16a6 in it. my clutch is sticking open so it's costing me like 3-4 seconds total in the quarter. i'm the president of a car club in victoria,TX and i got beat by my 2nd slowest car here a couple a weeks ago because of the damn clutch. basic point to remember....KEEP A GOOD CLUTCH IN AT ALL TIMES!!!!
