I am going with a boost set up soon and I am looking at ways to help aid in the survival of the bottom end of the engine. I thought I read somewhere that maybe Kurt Urban has a set up that allows the back pistons to cool better. I cant remember all of the details but our engines water cooling system design isn't the greatest as we start to lean on the performance edge and Kurt and possibly others have a set up that can be added to allow for better water cooling of the engine.

 

If your worried about durability id buy a cheapish set of forged pistons and be done rather than trying to "prop up" the stock bottom end. rods and cranks are plenty tough for most guys.
