yea the timing wasn't touched however I do believe those pistons lowered the compression down to 9.2:1 so I bet that took care of any timing issues. Back then there wasn't to many internals available for the car. I would say to anyone running nos that a good combo would be!

Bull frog head package and cams
defenantly some ferrara valves
9.2:1 comp pistons
stock rods will do but for boost I'd get eagles
The stock injectors will be fine for 150 shot nos wet system...if boost I'd upgrade
DC header and Greddy exh. with test pipe, and cold air intake.

If I didn't flip the car I would have eventually upped the shot to a 200 shot! When I flipped the car, the girl I was currently with at the time and I went out and bought a 2001 Teg Type R and a si blue prelude which I boosted for a short time. Got rid of that in favor of a GSX and H22 hatch. It just kept getting better
