what head to put on b20?

[projectsilvia97]

I'm not sure what head to put on the b20. Should i put a B16 head on or a B18c5 head. Also, i'm wondering what kind of compression ratio i should have if I want to go turbo. There's this place up in Michigan that does a whole B-series rebuild. I'm not sure what kind of pistons I should put in and what the compression should be on them.

Thanks.

pick whichever you want....they are both comparable, and both good choices...
probably go with the b18c5 since you want turbo, then you have some what of a port and polish done....
as far as compression for turbo.... 9:1 seems to be the norm...
i wouldn't wonder much higher than 10:1!

yeah if u wanna go turbo then do the b18c5 but if u wanna go all motor then do the b16

I think if you wanna go turbo all that matters is that you use low CR pistons, between those 2 options in heads I think it doesn't matter, both look the same considering your application.
