b18 vtec head
oh man ur cool...just cuz i don't know as much as some people doesn't make me dumb...i just have a family and a life so i can't sit and read about motors or take classes about it or anything...i have to run the office to put food on the table...
actualy, gsr heads have smaller combustion chambers and bigger ports than a b16. the intake manifold stock is the flaw, if u were to stick a b16 head on a gsr block it would yeild much lower cp witch would make it slower, but better for turbo, if i was gona use a head for all motor ls/vtec i would use a gsr to get the most cp out of it, but if i were to use a b16 head it would be for turbo because on a ls bottom with ls pistons its about 9-6-1. but wiht a gsr head its more like 10-1-1 or around there. gsr heads also have better cams, about 3-5hp difference. but what i like is a gsr combustion chamber, not round but kind of a rectancle or oval for more flow. idk what u guys are thinking when u say b16 heads are better, i dont think so, im pretty dam sure if u put a gsr head on a ls bottom it will yeaild more hp than a b16 head. but to maximise a gsr head u have to get some kind of aftermarket intake mani. just my .02$
