This is 2004 STi we finished up not too long ago. The motor had some severe oil consumption. We decided to freshen up the motor. We based it around one of our ML500 spec motors, with a few additions. Utilizing the Manley performance pistons we bored it out to 99.75mm re-using his case. Since we were in there we also installed ARP rod bolts and honed the big end bore for proper clearance. Everything got put together using standard ACL bearings. A Motion Lab performance 3-angle valve job fully re-built the heads and increased flow at the same time. The block on this particular motor was actually warped. We ended up machining .018" off the surface! We needed to make up for all the material removed so we used some of the superb Cosworth headgaskets. Threw in an ARP headstud kit and re-assembled to Motion Lab Tuning pro-built engine specs. After the dyno tune I think the car came out great!
