My left overs are. 2.3 longblock minus oil pan timing cover intake cam crank pully oil pickup. Thats about it i reused pretty much every thing.
Left over ford bits
Intake manifold, oil pan, oil pickup, oil filer housing, intake cam exhaust manifold ignition coils, flywheel cam sensor, temp sensor, oxygen sensor
I'm in the middle of a swap now - 2011 Fusion 2.5 (15k miles) replacing the rod-knocking 2.3 (154k) in my '05 Mazda 3 hatchback mtx.
It's going well so far but I have a couple of questions, if someone could verify please.
1) I'm trying to decide whether to use the 2.3 or 2.5 valve cover. I'd like to use the 2.5 coils because of the lower mileage but am not sure about the compatibility of the 2.5 coils with the 2.3 valve cover and vise-versa, or even if the 2.5 coils will work with the Mazda 3's electronics. I can't tell for sure whether thlillyr used the 2.5 coils but in one place he said he had the ford coils left over, so maybe he used the 2.3 coils?
2) I just saw where Artem Vestsorov posted on 12-18-2014 on the happywrenching thread the following:
"I'll say one more thing about the 2.5 swap - technically yes it can be done. Someone correct me if I'm wrong but everything that I have read states that the 2.5 cylinder head has larger intake ports and a different intake manifold. So, if you use your Mazda intake manifold, you'll get a slight air leak because the manifold won't seal correctly with the larger ports. Or, if you use the Fusion intake manifold you will set off the check engine light."
I test fitted the 2.3 intake to the 2.5 head and the intake is VERY close to not completely covering the larger ports on the 2.5 head. Can anybody that has actually done the swap comment on the possible intake leak issue that Artem posted? I'm worried that I'll end up with an intake leak either immediately or somewhere down the road.
Thanks
