Tuned this old P&L built 06 STI last week. It put down 652awhp at 30psi from a 6266 Precision turbo. It was built over 6 years ago and uses a completely stock sleeve EJ257 block with oem case bolts, CP pistons and Pauter rods. Some people would say that wouldn't last long but it's made it this far. Not saying it's the right way to do things but with proper tuning even a stock block Subaru can stay together.
