I have a 1999 Legacy with the 2.2 and as far as I can find, it would take A LOT of moolah to get more power out of it. I mean you can do things like upgrade the intake and exhaust work and things like that, but as far I've been able to find out, there's not too much we can do to get more power out of 'em. BUT if you have the money to do it, and the time and know-how, go for it! That'd be cool!!

High compression pistons, combustion chamber reworking, light port work, 5 angle valve job, cams for your desired tq curve, EL headers with a quality merge collector. Of course, all this stuff would require a tune to take advantage of it and that means a stand alone ecu.

Cams without a good header is leaving a bunch of tq on the table. Cams without a tune can be harmful to the engine if the factory ecu can not adjust timing enough.
Any way you slice it, the $ to power ratio is pretty crappy on n/a ej engines.

So, to the OP, doing the 2.5 block and 2.2 heads is about the cheapest power upgrade you can do for these cars along with some torque grind cams and opening up the exhaust some.

I'm actually looking to do this to my wifes 99 Impreza L since it has a rod knock. Her 2.2L heads on a 2.5L SB.

Look at paeco. They have three cam set ups and they can port/polish, oversize valves, knife edge the crank to find some lost hp.
