so i found a 5.0 in a ford explorer that has EFI. i was wondering if anyone has done a swap and used EFI and how they did this, and you had to modify/add. I'm wonderin if anyone could help me out. thanks.
yes plenty have done it... im in the process of doing it right now... you need upper and lower intake, fuel rails, electric fuel pump, run a return line, modify a stock efi harness, injectors, ecm, and alot of elbow grease i know i missed something so someone fill in the blanks its doable.. go for it p.s. get a mass air system and not a speed density... lots of saved headaches
\ There is a good probablilty the explorer motor is a mass air system they changed over in 92 if I remember correctly and the explorers didnt get 5.0's untill 95
yeah that's what it is. i'm going to go for modifying the harness to fit. but the engine is complete. everything's there. got lucky. it's a totaled car that i'm going to be able to rip it out of. can't wait.
You do need an upper plentumn that mounts the throttle body on the passenger side, also, the shock tower braces might need to be refabbed to clear. The C4's kickdown will need a cable instead of manual linakge. Find the inline high pressure pump, and run a return line back to the tank. I would build the harness from scratch, using old plugs from the stock harness. It simplifies the wiring to a 3 wire hookup once done. One key switch power, a constant power, and a ground. I do have a spare home made EFI harness for SD EFI, but MA can be added easily to convert over. Hope this helps a bit.
