i've got a 1996 cavalier with a OHV 2.2. and a 5 speed j cavalier basically i want to get to or as close to quad four power and torque numbers as possible... the catch... it needs to retain the stock injectors, intake, i am gonna see if a manifold from a s10 will clear everything, no port work can really be done. it needs to be done by advanceing the timing, high octane no lead race gas so i can run as much timing as possible, richining the A/F mixture.
it is in my buddys dirt track car, it is OBD II, it is in the rules all cars must be stock when it comes to the drive train, but alot of guys in his class are cheating, mainly with head work and raising compression ratios, but most are to stupid to take in to account the tuning required. plus the rules state nothing about a reflash of the vehicles computer. he had a custom pipe bent at a local shop, i believe 2 1/4 as opposed to 1 7/8, then we cut the old flange off the original pipe, welded it to the new pipe. it has no cat, is wide open to the rear with a 3 inch long "muffleling device" (basically a 3 in portion of a glasspack) i also would like to RAISE the revlimiter about 800-1000 RPM, i cant eliminate it though, cause the cars have to have them, and there really not supposed to be tampered with. again, one of those "gray areas"
also, any stock GM injectors that fit in the 2.2's manifold, possibly off say a 3.1, 3.3, or 3.8.? also whats a fuel pump that puts out higher pressure then a stock cavaliers that goes in with little to no modification of the tank.
ANY help and suggestions would be greatly appreciated, i mean anything, this is kind of a new breed for me but i want to go into it with both hands.
believe me ANY help will be appreciated
