I have changed the fluids throughout the drivetrain before doing anything else to see if the vehicle was worth rebuilding and everything is good.So far I have installed a 4 inch lift and new wheels with 33X12.5X15 YokohamaMTs,and replaced 2 worn U-joints. I am looking to do a head swap and add fuel injection . My question is, I have located a 1993 Cheeroke with 4.0, 5 speed, 200000km, that was wrote off in a rollover. What engine components from the cheeroke including wiring harness ,head,intake and exhaust manifold, distributor, will swap over to my YJ without to much trouble? Any breif step by step instructions as where to start will be very much appreciated? Also,what would be the lowest gear ratio I could go with and still keep the original axle cages? Thank-you

i would swap everything over from the cherokee into your wrangler, whole engine, trans, transfer case, wiring harness and computer. then you will need to install a grand cherokee water pump, belt, and a few brackets, why? because the cherokee has the clutch fan mounted on the side of the engine, the wrangler and grand have it mounted on the water pump in center of then engine.

Just to confirm,, I will have to change out the flywheel from the 4.0 to my existing 4.2, correct? Both are standard transmission. If so, I would think is it easier to drop tranny rather than pull motor? That does the word 'dizzy' refer to and will I have to do that? Thanks

Yes flywheel needs to be changed, and dizzy means distributor... I usually pull the motor to do flywheels

cevans87, do you, or anyone going through this thread, know if I can remove the autotranny wiring from stuff from my 91 engine wire harness with no ill effect? As on the first page of this thread. I am building a stroker, still building a stroker, for my 83 SJ Cherokee. I will be using my T176 so I do not need the tranny wires. I also do not need the cuze control and maybe some other connectors. I just need to know if I can take this stuff off without the ecm giving me fits. I know I need to ground one of the pins on the ecm since the engine harness and ecm came out of a automatic.

thanks for any info.

Just an update. My '88 YJ is still running strong ever since my '93 XJ 4.0L HO conversion. It had no problems starting in the dead of winter in -27 deg temps.

cevans87, Great thread it has helped make my swap much easier. I have a 89 wrangler and my donor is a 93 grand cherokee. I think i have everything wired right. I used a E2000 Fuel pump. I used the existing fuel hose from the tank to the fuel pump then i used the cherokee's fuel line from the output of the fuel pump to the motor. I can turn my switch on and the fuel pump comes on and goes off.(I kept doing it till the fuel pump quit coming on. Which i assume that means that the line is fully pressured.) I try to start it and it runs for 3 seconds and it is like is not getting enough gas. I can do the same procedure again same runs 2 to 3 sec and dies. What did i do wrong?

going through this engine wire harness, I cut out my VSS, will wire that back in when I get the part that connects to the tranny. Also, there is a large resistor in the harness, do I need to keep that? So what I should keep is the VSS, CPS, TPS, MAP, the other sensor on the TB, coolant temp sensor, air intake temp sensor (think its located on the intake, I am going to mount this to the air box/cool air intake), and O2 sensor. As far as the power dist. piece (rectangle box) I use that for fuel pump relay and maybe what other things.
I was going to try and splice this 91 harness into my 83 harness but think now I would like to make a stream line harness with a few splices into my old harness.
thoughts welcome

also would like to see an answer to BrandonReed2001 E2000 fuel pump issue, I bought a E2027 I think.
