i've got a GSR swap in my CRX and i was wondering if there was any performance differences between the B16 and B18C1 heads. My ultimate goals are 200ish whp daily driver. All i've got so far is a header and Zdyne.

 

your better off stayin the gsr head..

 

there is a post on here that show that the B16 flows just as good as the itr. i think the post is archived, so i guess the B16 would produce better #'s

 

but doesnt the b16 mke for slightly lower compression?

also i heard in a few posts, just p&p the gsr head and you will meet if not exceed the itr head. i dont know

b16 and itr come from same casting right?

 

last time i check that flow chart was for a gsr and b16 not a ITR and b16
