Nope, the ringlands are weak to begin with, but we had an issue with the external wastegate when we were trying to tune the car ourselves and she overboosted a couple of times, hitting close to 30 lbs. Also around that time I think my son stole the car and went joy ridding in it.....I raced A LOT and used the launch control on the AP A LOT!!!! So many ways the ringland could have been blown, no way to know for sure. There is no one around here that can rebuild a Subaru block, so going with a built short block.
