    Ouch man!!! I am sorry to hear about the motor. I cant believe you have the same issue you did last time. Sorry I wasnt able to lend a hand pulling it out. Perhaps I can help putting it back in.

    You and Fuji need to stop STEALING my ideas!!!

    Also if you are looking to get higher power levels on less boost, look into higher compression pistons. (flamers go away) bumping up from 8:1 or 8.5:1 CR pistons to something around 9:1 will allow you to get more HP on less boost as well as giving you better off boost driveability and faster spool.

    High compression on a forced induction motor does make more power with less boost, but the line between running it safely and detonating the crap out of it is much much finer. Tuning is much more finicky, and some weather you didn't tune for yet could be the end of your motor.

    Just wanted to let you know a little about my build. It's nothing fancy. I'm keeping my 2.2L of displacement. It's getting the #5 main bearing machined for #5 thrust bearing so I can run my revised WRX crank with double cross drilled crank. This with Cosworth bearings; main size1, rods size2. This mated to Eagle Rods, pistons will be from CP custom dish to match the combustion chamber of the '06 WRX heads with a compression ratio of 9.0:1. The EJ22T will NOT be bored out unless needed any. I want to keep as much of the sleeve as I can to maintain strength. It will just get a hone then measured so I can get the pistons to the right size to get a desired piston-to-wall clearance. The crank will get rotated balance, so we'll see just how off it is from factory specs. A JDM 12mm oil pump is being used and I'll be using a STi oil pan.

    When shooting for high HP with high boost (25psi+) on the EJ257/EJ255 blocks, I'd recommend getting it resleeved with stronger sleeves or even going wet sleeves. The cylinder wall sleeves are thin on the 2.5L blocks. With the 22T, if wanting to go 100mm pistons, it's a tough call because you're shooting for high HP. It'd be ideal to sleeve it as well if boring it out. This is why if that then you could just sleeve the 2.5L you have if it's still in condition to get sleeved.
