which is a better engine to boost: B18a or B20z?
 

i know the B20z has weak sleeves.

which engine would be the best to turbo?
how much boost can a B18a handle before you have to build it up?

b18a will handle more boost but the b20z has higher compression and will make better numbers at lower boost. but the b20 sleeves lick ass. also u might wanna do b20b and not z :)

if i were you i would go b18a because they are a dime a dozen.
