I would like to get a list together starting with the engine parts most likely to fail first under high force induction pressure. I was thinking head gaskets and piston rings would be of most concern. What do you guys say, I know at least some of you are running boost. Thanks.

 

pistons and rods, the gaskets and rings are fine.

 

Would a forged crank be necessary?

 

Stock crank is fine unless you're shooting for insane hp levels. Let's put it this way...I've never heard of a stock one breaking....

 

If you're going to be running lots of boost forge the bottom end. Get some 6.0L heads either way
