hello, i am in the process of turbocharging a 92 ls b18 motor. I am planning on doing everything but sleeve the block, the problem is that i have been told that i cant use aluminum or steel pistons in the b18 cast iron block without sleeving it. Is that true. If not what kind of pistons do you guys recommend. THANKS ALOT

 

They were thinking about the H series engine.. i've never heard anyone say that about a b-series

CP makes great pistons..
