Do you guys recommend this setup, basically gsr head and tranny with the jdm 92-95 sir block?

Or should I just go with the usdm gsr block?

 

I think youll get more power with the b18c block, so Id stick with that. Now swapping on a b16 head onto the b18c block works well cause it doesnt have the huge intake and secondary blutterfly intake. If I'm wrong anybody feel free to correct this ****. Peace, late.

 

dont you lose compression by switching from a b18 head to a b16 head on a b18 block?
ii am really asking, cuz im not sure

 

yes compression will be lost, I believe the cumbustion chamber on a gsr head is square and yeilds more compression.

 

yes whatever evocelica said but b16 have better flow by about 5%
but you can make your b18 have better flow

 

not sure about the flow I understood that the gsr head and b16 head are the same besides the cumbustion chamber. I could be wrong

 

maybe you should just stick with the SiR head and get a mugen or spoon headgasket and later on down the line get some better cams and either an ITR manifold or skunk manifold

 

i plan to do ls/vtec

 

then use the b16 head with a thinner headgasket and get it port and polished the whole 9 yards. I would suggest portflow, Tom does great work.
