Need Conversion Advice!

I have an old, but solid 1990 YJ that has the I4 engine, but its burning oil pretty bad. However, I also happen to have a 1997 Ford Explorer with the 4L SOHC V6 that was in a roll over accident. I was considering swapping the Ford engine into my wrangler (it really is a nice engine). However, I can't find any info anywhere for a switch like this. Has anyone ever seen/heard of one? Does anyone have any advice as to what I need to be careful of//look into? I know Ford V8 windsor engines are popular swaps, and there are conversion kits everywhere for them. Would the windsor conversion kit work with the V6?

I think you will be on your own on that swap. The windsor stuff is totally different. Its a doable deal though, you would need the tranny and case of the explorer as well as the harness and ecm. All you would need to do is get a ford manual and figure out the wiring, make some mounts for stuff, and go for it

I agree with Ibuildembig and while your at it transfer in the rear diff from the explorer as well....All you'll need to do then is have the explorers rear driveshaft shortened and have the front driveshaft adapted to the D30... I say go for it... good luck.

Do it, but make sure you post pics. I've never seen a swap like that, but anything is possible if you're good with a welder, have a large garage, and a wide variety of tools.

Alright guys, thanks for the advice. It looks like I'm gonna do it, although I'm swapping into a '95 YJ instead. I'll def post pics in the end, but I was hoping I could get a 'lil more help with a couple of questions...

1.) I'm going to swap the Explorer rear-end into the jeep. Does it change the wheel rim bolt pattern? If so, how do we change it back so that all 4-wheels are the same?

2.) What is the best way/source to change the rear-end gear ratio to accommodate for the larger tires (35 vs. stock) on the stock front end and on an 97 explorer rear end?

3.) So we are going to take a 95 Ford Ranger manual N50D 5spd and transfer case to fit our Ford 4L SOHC V6 good engine (from 97 Explorer). Does anyone know how to adapt the speed pickup output from the transfer case to provide both electrical signal for the engine controls (ECM) and mechanical input to the dashboard speedometer?

4.) What is the best method to calibrate the speedometer to fit the new larger tires?

5.) We are going to drop a 4L SOHC V6 engine (because we have it and it is very good), with all its harness and computer into the 95 Jeep that came with 4cyl 2.5 engine. Will the OEM fuel pump be sufficient for the fuel injected V6? Is there even a pump in the tank on the Jeep. We may need an inline pump.... what/where is best?

6.) So we are going to take a 95 Ford Ranger manual 5spd N50D and transfer case to fit our Ford 4L SOHC V6 good engine (from 97 Explorer). Is there a good resource for linkage adapters to accommodate for the different shifters on the 5spd and the transfer case?

7.) Any one ever had an issue with the steering column ignition damage due to "mishandling" the steering wheel on entry? That is, previous owner was using the steering wheel to pull himself up/over into the seat that caused ignition cylinder damage... is there a known fix to that (other than stop doing it...)?

If you can't tell, this is going to be my first jeep project, so any advice I can get is hugely appreciated!!
Thanks

If it was me, I'd try to use as much of the ford as possible if you want to do it.

But, thinking about doing that myself I'd be creating much more work than investing in an I6 or even another 4 Cyl. to bolt right into the Jeep... Using another engine and using another everything is wayyyyy different when you really think about everything you'll need to do. Just my opinion of course... if you have the time and tools, go for it.

Thats gonna be real cool if you pull it off....my buddy has a 97 explorer sohc with a chip, pipe and intake and the thing is making some real good power. I personally am going to go the windsor way. I used to have a car with the 5.0 302 in it and loved everything about that motor so im hoping to put one in my YJ
