to get a bigger displacement? I was talking to a fellow enthusianst and he said that the cylindar walls might become too thin to support the amount of boost that these engines run (Stage III). What do you guys think?
Just tryin to get things moving here...

How thick are the walls?

search the archives for bollocks for more info. I've almost got my spare engine tore all the way down, after which i'm going to ultrasound it to figure out just how big we can go.

didnt give any details on the replacement though. Said something about only getting a few k miles from the 2.8.

You can basically keep dialing up the boost until something blows up. Seems easier than boring out the cylinders and getting custom pistons.
