Im looking at a ESRT s2 but Ive been told that compresion is down on one of the pistons, due to a piston ring breaking down.
How much would a engine rebuild cost me?
engine spec is
185 PTS chip (15psi boost)
Piper cam
-31 actuator

Any help would be great. I really want a S1 but this seems a good deal if its not to costly to put right.

thanx
