Okay I got a question before I start purchasing parts for my rebuild. I want to have bigger size pistons kinda of like runninng a big *** 1.8.

I am planning on running boost on this engine so I was planning on getting some sleeves, so if I get bored out sleeves to match the pistons do I need to get the block bored to fit the sleeves??

If I get oversized pistons what is the best size for a 15psi boost app.?

How much bigger should the sleeves be from the pistons I hear .0004 is a good cylinder to wall clearance.

Anything else I should consider???
