96LegacyEJ22

EJ25's like to spin rod bearings. I drive hard. EJ22 heads are the WORST flowing heads Subaru ever made. NO top end power. The EJ25 heads on the other hand are much better for top end too. Anyways. So cooling the Intake air won't do a single thing?

The way I look at it is. Why take the two ************tiest parts of the motors and put them together for a giant ************ty motor? Yea you gain more power from the compression. But the 2.5 bottom end sucks and the 2.2 heads suck just as bad. If anything I will go with a full on 2.5. Figured hell, why not make the 2.2 a little more torquey. But everyone is advising against everything with them. I suppose I will stick to the Hybrid intake and Exhaust. Until I move on to something bigger and better.

Most are running a happy medium at 89.

What about sensors and all that? The 92 has no EGR. So I would assume I need a Manual IM.

Do the 97-98 Intake manifolds bolt onto the 90-94 EJ22 heads? My friends 92 LS intake manifold is always so warm. I have read that the 97-98 IM flows better then the earlier years. Such as my 96. I was going to put Grimmspeed Phenolic spacers on her car. And while I was in the might as well give the IM a little more flow with a newer one.
