I own a 1998 legacy l with a 2.2 also. to my knowledge we cant do much with our engines. our engines basically stay stock. i have been searching for a year and i only found one thing and it is out of stock everywhere. it is a single port exhaust header.

I heard you can put 251 cams in to increase throughout the entire power band without any modification to the ecu.Also another option is to find a junkyard 2.5 longblock and drop that in.

251 cams only for phase 2 2.2's

a 2.5 long block is a wiring challenge

apart from forced induction the 2.5l short block 2.2l head combo is the most cost efficient way to make more power

op get a NA 2.5L (doesn't matter what year just as long as it's an ej series) and bolt your 2.2L heads to it, run 89 octane and be done with it

everything should match up perfectly, only change is the head gasket and the crank sprocket ( use the one from you 2.2L )


with MY94 heads I'd figure the comtec gaskets designed for this combo would be your best ( read this thread too: http://forums.nasioc.com/forums/showthread.php?t=631527)

you can rent a valve spring tool from advance or auto zone that looks like this:

makes taking the valve train apart much easier
