Does anyone know what pistons I can use on a b20b block with b18b head? everything on the internet is figured for a b20 block with a b16 head. im looking to get 11:1 compression with wiseco pistons but i dont know what ones to use since they base everything on a crvtec setup. if you know how i can figure this out or know off hand please let me know.

 

any vtec piston will be fine its just the valve reliefs that would have been the problem non vtec to vtec / but vtec to non vtec is fine

What i am wondering is what piston to use to obtain 11:1 compression since the b16 heads are different from the b18 heads. i dont think i can go by the compression they list for a b20/b16 crvetc setup.

11:1 compression? call wiseco and specify youre setup. They should be able to give you some pistons tailored to your needs.

maybe i am reading the original post wrong, but he says he is using a B20B block. b20b = 84mm, any vtec = 81mm. that means there are no vtec pistons that will work.
