Forged 2.0L build. Cold start at 12 degrees. This engine has about 1500 miles on it so far. Mild forged piston slap can be heard. Wiseco pistons, BC Crower rods, Subaru x drilled forged crank. .0025-003 Piston to wall clearance. THANKS to my wife for letting me build this in the living room and not out in the cold :). Your the best baby!
