"By speed proportional and non speed proportional pumps, are you referring to variable or non-variable ratio steering gear?" Not sure, but I was always told the pumps were the only thing that was different, because of that sensor in them. I'm not sure what the sensor did exactly. I could be wrong, but I always thought the gears were the same.

I never once said, not to use the zj gearbox, not sure where you got that. I was stating the power steering pump had a sensor, that's what the difference is between speed proportional and non speed proportional pumps on a zj. I was also stating that the zj steer gears were the same between speed proportional or non speed proportional. Maybe I didn't make myself clear enough, I will try better next time.

The zj pitman arm is the same one thats sold as a drop arm for lifted xj and mj's. If you aren't lifted then reuse your original one. The speed proportional steering zj's had a sensor on the p/s steering pump. I believe the gears were the same.

I was just saying,the dist will go in and work. Sorry just trying to spread a little of my useless knowledge.

The cam sensor has to be bolted in place, it goes where the dist would be,for the coil on plug ignition to work. Check on the internet, there is a place to bolt it down, its just a dist stub shaft with a sensor in it.

I understand on the injectors, I'm just cheap, and the ones I got were free. My 88 had the same problem as yours, where the injectors were leaking so bad, it washed down the cyl walls. I know the cranks will interchange, I had a good 94 crank that I sold to a friend with a 01 tj, and it went in no problem. You will just have to pull your 88 crank out and compare it to the 00. I tossed my last non ho block and crank about a month ago, or I would check for ya. I have a 97 xj motor on a stand now thats getting rebuilt, that has the crank out. I could of placed the 88 crank in it for you to check...Oh well

You would have to use the renix tps with an aw4, or it would never downshift, and shift up so quickly it would bog.

87-90 xj's and mj's used that bottle. I have bought used ones from the pick and pull, most of them have been replaced over the years. I'm cheap though. The dealer will stock them too, part #'s are 4720363 for the bottle, and the cap is 52006707. 15 yrs in a jeep dealer parts dept, been away 2 1/2 years, and still remember some of the part #'s. I sold a ton of those bottles when I was there.

Don't worry, I have a couple of spare gates, and it looks like you are near me. I'm in Belton, so it could be easily replaced, but I don't think you have to worry. How many comanches do you see around us? I saw one yesterday, but it had been 3 months before that, that I saw another one, and it was at pick and pull. The clamp is a good idea though.

On the sensors as well, the one near the oil pan is the knock sensor, and it can be added to the 00 engine. There is a threaded plug there, just remove and install the sensor. I'm not sure on the coolant sensor though, mine had a spot for it at the back of the head, just like the 88 motor. On the 19lb injectors, go to the salvage yard and pull them out of any 4.9l 6 cyl or 302 with multi-point injection.They will be orange, and take a old jeep one to verify the connection. Mine were out of a friends 91 mustang, when he upgraded to bigger units.

99 and later WJ and TJ blocks are diff. They have motor mount castings in diff places, and they use totally diff acc mounting holes. Don't ask me how I know this, as I bought one for my mj, and tried to bolt it in, wrong it wouldn't work.Salvage yard wouldn't take it back, so I had to sell it on craigslist for a loss, and buy another. All 4.0l 87 to 01 xj blocks will mount in the original location in a xj or mj. The 91 and later 4.0's had a boss cast in the right side of the block to mount the coil. Thats the major diff from the 87-90 and the 91 and ups.I think in 97, if I remember correctly the 4.0l's got a steel main cap brace, but just minor changes after that.I think in 98 or 99 they started using skirt coated pistons, to do away with piston slap.If you look on the pass side of the block, each cyl will be marked with a grease pencil with a letter. This is the final bore size, and they are never all the same. Its A,B,C, and D if I remember, and you can buy pistons in that size but you had to know the letter.If you bought a replacement piston, it came on the rod, ready to go. They say the heads are diff, and they might be, but I have used non ho heads on ho blocks. I've also used ho heads on non ho blocks, with no trouble. I worked at a jeep dealer for 15 years, and saw the changes first hand, I have also owned so many xj's and changed the motors in most of them, that I don't dare to count. Its such a shame they dropped that fantastic motor...Oh well good luck.

I have 25k miles on a 00 xj engine swap in my 88 mj. I reused all my renix injection parts, and all the accessory stuff from my 88. The dist will go in no problem,and the 88 flex plate went on without a hitch. Now mine is a aw4, so I'm not sure on the manual trans. If its diff take your 88 crank and have it turned, and add new bearings and put it in the 01 block. The cranks are easily swapped. I also added ford 19lb injectors, and remember to swap your oil filter housing too. The threads are diff on the 91 and up oil filters. Hope this helps, anymore questions you can email me @ qwk2race@aol.com. By the way guys I'm new here, just found this last night. Cool site though.
