Default ej25 intake on an ej22

Well, the question is clear I guess. Does it fit? any gains? or is there anything from a 2002 ej25 that would fit on a 1999 ej22 without doing a complete swap?thanx a lot

I dont think so. The ports on the EJ25 are larger, and IIRC spaced differently.

Close, but not quite. If the EJ22 is the earlier type, the EJ25 wont fit. Since it's a 99, it should be doable.

I thought the EJ22 didnt go phase 2 heads until 2000-2001, when the heads closely ressemble sohc EJ25 heads.

I have both at my dad's house, maybe I should compare.

I think based on what I've read in the past that they EJ22 and EJ25 intake manifolds are not compatible. Check here. Granted, that's just one thread, so there could be some bad info there.

I've got an 01 EJ22 manifold and a 99 EJ25 manifold in the garage at the moment. They appear to be identical. That would make me think that there wouldn't be any gain in swapping.

You can study the FSM specs on the cams to see if the EJ25 cams will drop in to your heads (I'd like to try this myself) and see what happens. Other than that, slip a phase II EJ25 block under those EJ22 heads and have alot of fun cheaply!
