So some of you have been following my Plan B build, but I thought I would do a separate thread on the engine swap. My swap will need to be California smog legal, and I'm using multiple donors parts from different years for the build.
Why the SOHC?
I understand this is the first question asked. Simply, because I had a perfectly good complete donor, and the motor only has 103k and runs super smooth. No chain noise. Plus out of the box, it's the same hp as the V8.
We're Starting off with a 1991 Mazda Navajo (Explorer Sport).
The donor vehicle I'm using is a 2000 Explorer Sport
Everything for the most part should just bolt in. As I'm basically just swapping everything over to a newer body.
