When I got it it had a CBE, crappy intake, v1 Turbo XS utec (fred from capitalland has it now)and ran rough. I brought it to synapse to check it out and bought an oem intake and exhaust, we found out the timing had skipped due to maintenance not being done. They also did the fuel return line fix, and when they took the IM off they found out the heads had been ported, and it has cosworth head gaskets. When they fired it up they also were finally able to tell it has the sound of a subaru forged engine. rather noisey… I have been talking to seth moon and he pretty much identified the pistons for me sight unseen. I guess early on CP used to has loose tolerances for they ej20 pistons. I was planning on a tune this week but the radiator cracked. The new all aluminum unit should be here thursday, then I am replacing the IACV gasket, getting that cleaned out, getting 4 newer tires and an alignment then I’m getting tuned finally ! The slugs could be any number of aftermarket pieces, so “identification” by noise isn’t quite that easy 😉 CP/Pankle, Wiseco, Ross, CW, etc all make pistons for that motor. However just because their noisy doesn’t necessitate that it’s a built block. OEM’s can be noisy as all hell too after a beating. Easiest way to tell is with a bore scope down one of the spark plug holes where you can inspect the dome of the piston. If you don’t have one of those, and are doing the timing belt, you can easily see by pulling one of the pin access plugs on the front of the cases and rotating the engine until you can see the slug at the pin boss. The OEM vs forged pieces have drastically different pin bosses that you can see though those holes. Or if you pull the motor and oil pan, dead giveaway by looking at the piston pocket at BDC. Early CP’s PWC was .004, it’s now down to .003 with their new alloy composition, however I typically setup in .0033-35 range for forced inducted engines that are “going to be abused”. NA get’s .003 regardless. Suby’s have a tendency to be noisy due to their short skirt design anyway and the increased PWC of a forged 2618 alloy slug just amplifies that. Just a by-product of the case design really. --- _[View the full topic](https://forums.speedlife.net/t/turbocharger-recondition-service-56k-die/241959)._
