Why not finish the Explorer swap?
Do you already have the harness from EFIGuy?
Years ago I scored a real nice 94 wrecked Mustang 5.0 HO that I installed in my 1983 FSB with a ZF 5 speed. I cleaned up the harness and used the emissions equipment so it would pass the Colorado inspections, Came out great and ran beautifully. I got a 3 part article published in Bronco Driver.
I picked up a nice rust free 69 EB with a bad engine and 3 on the tree. Picked another 94 doner mustang that turned out to be junk. Bought a nice running 98 explorer 5.0 auto. Made a lot of progress and had a thread going. That is in archives. “ODB Next Generation”.
The project got stalled with a house remodel, job change, health issues, and a move back home to Michigan to care for my folks. Long story short, I need to do something with the Bronco. I’ve been intrigued with the coyote transplants But am considering completing the explorer engine install. The explorer engine ran “ok” on the stand but is pretty high milage and should be overhauled. I was originally planning on installing all of the emissions gear to make it Colorado compliant. That’s a lot of equipment from that 98 explorer. Plus the damned PATS.
If an aftermarket control system is available for the Explorer 5.0 / 4RW70W I’d be interested on continuing that path.
Is EFI guy still around? what was he selling?
