Well I have a little while before I go turbo but out of curiosity are hypereutectic pistons direct drop when rebuilding? Or it doesn't matter if you go forged or hypereutectic you still need to machine the cylinder head for clearance? I ask because I have some experience with rebuilds so I was wondering if I got hypereutectic pistons with forged rods and a forged crank if it will be as simple as rebuilding the engine with them or I have to still make sure the clearance is right. Now before any one flames me and says forged is the way to go I was thinking of some of the draw backs of forged and it possibly might be easier to go with stronger cast pistons. Plus I'm not looking for more than 250 whp maybe eventually 300. I know stock internals could handle that Just wanna make sure my car will still be reliable as it is my dd.
