I was originally building up a 2.2L stroked to go in my 99 GC8 WRX but ended up selling it and buying this instead. At the last minute a changed to a 257 block and 99.5mm Mahle pistons. Plus the original EJ207 had 162,000 kms on it so not sure how long it would have handled the power for. It's at 273.9awkw on 15psi. Can't wait to see what it has after the motor is run in and the boost is turned up
