I found on JEs website that they have pistons available for the wr's. Here's the problem. They told me there wasn't enough of a demand so they pulled production. They said they could make me a piston. But I'd have to get 2 made. I have no use for 2. So it would be 520.00 for 2 pistons, rings, pistons, and locks. So if anyone wants to put a high comp. Piston, please email Brian weaver at JE so we can each get one for 260$.
