ok so i want to buy a b20z2 but most of the b20's i see on line only say b20 how do i know which one is b20z2 because i heard the b20 has less power then the b20z2 so can someone help me out

 

The only difference between the b20B and the b20Z is the different intake manifold and slightly different cams (if i remember right).

youre probably not going to use the b20z IM anyway...so its negligible
