I'm in the planning stage of building my motor for turbo application. I'm buying a set of wiseco forged pistons. Do I need to have my block sleeved? I was told that the K block is just like the H22, mylar sleeve, therefore, I need to have my blocked sleeved. Anybody with experience please respond. Thanks.

 

How much are you planning to boost? That might change what you need to do to your motor.

 

as far as i know, you are going to need to sleeve if you run forged pistons.
