Default just a thought....

Would mating a 2.5L doch heads to a 2.2L block make a good combination to put together? If so what are the benefits (pro vs. cons)?

The DOHC Ej25 heads with an Ej22E bottom end combination would only be recommended for those looking for boost. The compression ratio is in the mid 8's. This would be totally driveable as an NA engine, but what's the point of the trouble of making the change if you aren't looking to get some real power out of it. Turbo-charge that combination and you are in business. Check the AFI forum for a number of people who have done this build...

well the funny thing is I still have the old turbo upgrade from my old 2002 WRX (HIH VF22) I'm sure I could boost that engine and use the old ecu. Sounds like I might do this. I'm getting the block for free anyways.
