2.7L overbored 2500 2 months, 3 weeks agoI have a PI engine sitting in the shed and I am wondering if it is a good idea to overbore it.

For anyone with a 2.7L engine or planning the upgrade.
I guess that depends on if you can find the right head gasket. I believe my pistons are intended to go in a Mazda and are hepolite. I’ve heard of good torque gains coming from the 2.7L on SU and standard cam. Are you planning to do anything else i.e. cam grind?
