That's a good idea! I might have to do that to the SS.
Today I went to a pretty sweet maching shop that does a ton of subie builds. Sandrails, airplanes, racing motors. Talked to a few of the guys and they were super cool and helpful. I saw a sleeved 22T they were building.
I might sell my 22T and use the proceeds to boost a 22E block. I found a phase 2 shortblock for $50. I might be picking up some wrx heads for $150, and a set of 257 rods and .020 os wisecos for $200. Already have the wrx ecu and harness, and crossmember. Could be a nice budget build.
