Can these two Phase 2 engines be interchanged? Just swap the Intakes?


Based on Wikipedia and a couple other sources these EJ25 SOHC engines came w/either MAF: EJ253 or MAP: EJ251.

My concern is I'll get a CEL if the MAP isn't there on a MAP-equipped car....and the ECU expects it TO be.

And what's weird is they weren't consistently applied. The '99 EJ251
(MAP), was replaced by the EJ253 (MAF) in '00, and returned in '05??!


Thanks for any clarification.

Swap the intake manifold over along with the wiring attached to it. If any of the other sensors are different, make them as close to the same as you can. Everything should find a spot to bolt in and hook up to.

I don't think you'll have any issues with CEL's, especially if you swap the manifolds.

Got an 04 engine in my 01 and that's what I did.

Remember to change the camshaft sprocket with the one with the original engine. Mine wouldn't start due to the timing marks when I swapped for newer heads.


Original on left. Newer one on right!!!:icon_wink:
