I recentley blew the head gasket on my 95 gsr and had it fixed, while in the shop I put on blox stage 2 cams, skunk2 v.springs and retainers, manifold, b&M fpr, typeR pistons s2000 tb, with mach porting and honing. my problem is since I got it back it revs to about 4700 and then makes a funny sound like theres a rev limiter there. if I push past this god ofall noise then at 5300 the car will take off without problems untill the next gear. Has anyone had this happen and maybe know the answer of whats wrong, anything would help. I have a stock ignition system and stock ecu, could this be the problem?
