2000 Jeep TJ motor in a 92 comanche

[Codybelec]

I bought a 2000 Jeep tj motor for my 92 comanche that I bought with a blown motor thinking it would bolt right in.. it didn’t so here’s what I had to do to make it work. It started out I took off the coil packs and bolted in my distributor and timed it.. the alternator, water pump and fan bracket all line but some holes are blind and need to be drilled and tapped. I decided to mount the alternator where the a/c was since the motor I bought didn’t have it. I bolted on intake and exhaust and had my flywheel turned down at work I heard after the fact your not suppose to but it seems to work. I bolted the tranny onto the block and went to drop it in. The engine mounts didn’t line up so I used the old mounts but had to cut and modify the driver side to work. The oil pressure sensors back by the fire wall so you need a 90 degree fitting to angle it away but factory wiring will reach and plug in, same with factory alternator wiring reaches up top. I ran my new belt with rope and brought it to the parts store to have them match it. The coolant sensor that use to go back in the block the hole isint there anymore so I drilled and tapped my thermostat housing so I can see if it’s overheating. To mount alt up top you need to cut mechanical fan off and run dual electric fans. Any questions comment and I’ll try and help out. My only reason for doing this was I bought the wrong motor and made it work.

did you used the wiring harness that came with the Tj motor?

[Codybelec]

No I used comanche sensors and all the Comanche wiring

I can not tell from the picture... does the 2000 TJ 4.0 come with the horse shoe intake?

I started this type of swap years ago. I did not complete it. I had to put a spacer on one side for the motor mounts, and cut and weld on ear of the other motor mounts. Drivers side I think.  I put a '95 head on it. I remember mine be an '02 GC motor. I was thinking of running electric fans for cooling and keeping the accessory drive as the '02. There is a threaded boss in the newer heads for an Idler pulley. 

     The intake was the newer 'horse shoe' type. There is a difference between the XJ and the WJ intake. The number of bolts to hold on the throttle body/transmission cables is different.

I stuck with the intake off the Comanche just because I was able to sell the tj intake and exhaust manifold to make a bit of money back so I’m not totally sure if they fit
