Boost question

[Diesel_Wagoneer]

How much boost can I run with the stock pistons on a 6.2?? If i install a Stud Girdle Kit and a set of ARP head stud's with a good head gasket? Also I've heard compression ratio is like 21.5:1 is this true?

Depends on the turbo, intercooled, etc. I'd say max of 15psi with stock C/R engine that is healthy with good gaskets etc. and intercooler.

12psi without.
