my question is this..i have a built GSR bottom end. 9.7:1 compression wiseco pistons, crower rods, STR block guard. bored to 81.5mm. there is a fully built b16 head in the shop that is not being used. i am concidering putting that head on my GSR block. the head is fully built with hardened race valves, valve springs, ratainers, guides and is ported and polished with a port matched type R intake manifold. i think the b16 would lower my compression a bit which would allow me to run some more boost do you guys suggest putting this built head on (wana rev to about 9k rpm) or just stick with the stock GSR head. also i have a 1,2 and 5 LS gear in my GSR tranny ( 3 and 4 are gsr ) i am going to be running 15psi daily with neptune and a t3/60-1. going for 400whp on a dynojet. any input is helpfull. thanks alot

i posted from a friends house, forgot to mention i will be using stock GSR cams in this b16 head. what compression ratio am i looking at with 9.7:1 pistons with the b16 head?

 

I think the compression ratio would be around 9:1 if I'm correct, and yes I would reccomend using the head.

 

I hear nothing but good things about GSR botton end wit a B16 head....also known as "the poor mans Type R" where im from. I'd definetly recomend also

 

sweet thanks, i look at it as an opportunity to run more boost
