Need head swap input/advice. 2,5 DOHC to 2.5 SOHC.


Recommended Posts

Won't be able to make that swap work. Not easily at least. That SOHC engine has too many differences in electronics. You would need heads intake manifold, and the whole wiring harness and ECU to go with it.

Much easier to find a 95 dual port 2.2 and put those heads on the 2.5 block. Still need the manifold to go with the heads, but the electronics are identical to your 98, so you just plug the manifold harness into your existing ECU and go.

This swap will raise your compression and require you to run premium fuel though.
