i was wondering it this would work? would it be better for turbo apps? Thanks

 

Most people will say that both heads are identical. They are identical except the exhuast cam on the b20 head is a little less agressive. Both will work though and the difference in the cam is very small, you won't even notice.

 

i also noticed that the B20Z (the one i would like to get) has about 146HP while the B20B has 126HP. Are both of these heads Vtec? will i be able to get the 146 hp just by changin the head? Thanks

 

neither engine is vtec

 

niether one is vtec...infact the difference in HP is the compression ration...dont quote me but i think that b20b-8.6:1 b20z-9.4:1

but the HP difference is the C/R not the head
