on my 2000 gs-r i have a port and polished head, 3 angle valve job, and shaved 30 thou, itr cams, aem cam gears... would this head be alright for turbo or is the compression to high? should i keep this head or get a civic si head to lower the compression... what psi could i run with the gs-r head with a stock block? and what psi could i run with a civic si head with a stock block?

i am selling the gs-r head or trade for a stock gs-r head and cash or a b16a head and cash...

your CR is too high, going with a B16a head will drop your compression into the 9.5:1 area, which is pretty good for boost. I'd swap heads if I were you.

ya thats what i thought also i wish i could do turbo on this head cause when vtec hits right now all motor damn does it pull i could only imagine with a turbo but oh well i guess i'll have to get rid of the head or just get acouple head gaskets and put on there... lol

or drop your compression and do your bottom end with crower/je's..8.5:1 with your head should be fine.

hey fast94gsr u have aol right im me tsjag17@aol.com i wanna ask u some questions and see if u could help me with something,,,

ummmm.......i dont think so...the compression on the Si is 10:2:1!!!!!!!
by putting on the b16 head.....how is that gonna lower the compression to 9??

TurboInteg95

the B16 head has a slightly bigger combustion chamber I think. that would lower the compression.

SiRkid.....that compression on the si is almost all in the pistons.. Putting the bigger combustion area of a Si head with the gsr pistons will yield about 9.6:1 compression.......baaah
