i got a 98 GSR engine, im gona be rebuilding it to hopefully have around 12:1 comp. and i was thinkin i might wana do a NOS set up also cuz i cant realy afford the trubo, can i do that high of comp. and still do NOS? will it make me faster? or will it blow my motor up faster?? and how much is a set up usualy cost? also i am gona be replacing the pistons, valve headware, mill the head and square the block, what would i be looking at for a good shot of NOS?
