  1. But, going back to my original question, nobody has heard of this kind of swap in a Jeep?
  2. They're one of the few good engines Dodge ever built. My dad has one in an old Dodge A100 van (the van that inspired the Scooby Doo Mystery Machine). Anyway, my dad, on several occasions ran the engine with little to no coolant for a 15 mile trip from work (radiator hose blew off a couple different times) will no ill effect. Also, he let it sit for about 10 years and decided one day to start it. Got some fresh gas and turned it over, and it ran like it did the day he left it. That's pretty remarkable for an engine that's 48 years old.
  3. Get a cluster with tach from a '90 XJ or MJ. You'll be glad you did.
  4. Has anyone ever put a Dodge Slant-6 engine into an MJ or XJ? Just curious because the Slant-6 is even more bulletproof than our beloved Inline-6. Also, would it be possible to make it Multiport fuel injected and use the Renix or HO system to run it?
  5. Are you sure that the cluster you got is original to that '87? If it came from a 4 banger, it should work in your 4 banger. I know when I did mine, it came from an XJ with the Inline 6 and the numbers were way off. I suspect maybe the previous owner of that '87 may have pulled cluster from a Jeep with the I6 and didn't calibrate.
  6. Look on the fuse panel for a blank space that says "IGN" or "ACC". Either of those will work, the only difference being that "ACC" will work with the key turned backwards and in run, whereas "IGN" will only work in run. Make sure to put an appropriate size inline fuse when you run that wire.
  7. Thought this was interesting. Never knew of the Cummins B3.3 until now. 34 mpg out of a Jeep? Can't beat that! http://www.rockauto.com/Newsletter/archives/101812.html Dave's 1986 Jeep Comanche This is my 1986 Jeep Comanche. It has a Cummins B3 3.3 liter diesel engine. All of the accessories are from the original 2.5L Jeep engine. The AC compressor, expansion valve, drier, all 4 shocks, and steering stabilizer have all been replaced with parts from RockAuto.com. I travel 50 miles per day and consistently get 34 MPG! I now have over 130,000 daily driven miles on the diesel conversion. I love this truck, and RockAuto has helped me keep it going. Thanks, Dave in Georgia
  8. On a side note, I found this in the interwebz and thought this was awesome...
  9. Yes. http://www.ebay.com/itm/XJ-ZJ-CJ-MJ-JEEP-Wrangler-29-Tooth-LONG-Shaft-Speedometer-Gear-Cherokee-Mopar-/251286397611?pt=Motors_Car_Truck_Parts_Accessories&hash=item3a81d622ab&vxp=mtr
  10. I would not be his friend anymore... lol.
  11. Not true. 91-92 and some 93 models used long shaft speedo gears; all had electronic speedometers. Manual or auto transmission does not matter. The correct speedo gear tooth count is determined by tire diameter and rear differential gear ratio. Also the plastic gears themselves are the same for all. You can swap the shafts between the gears easily. Not true. 91-92 and some 93 models used long shaft speedo gears; all had electronic speedometers. Also the gears themselves are the same on all. You can swap the shafts between the gears easily. This is because the early electric speedos were just an electronic adapter that attached to the sender the exact same way the cable did. The later ones were integrated, which I believe is when they switched to the short shaft. Well, I just learned something new then lol. I was (mis)informed last year on another forum about the speedometer gears apparently. I guess it pays to do a little more reading. It even has a breakdown for the different years in the first link I posted... :doh: But thank you for the clarification.
  12. Refer to these links. Not sure if it matters with it being a manual or automatic, but I'm pretty sure you need a 29 tooth gear, long shaft. Long shaft is for cable driven speedometers, short shaft is for the electronic driven speedometers. Yours is obviously cable driven being an '88. http://jeep-xj.info/HowtoSpeedoGears.htm http://www.quadratec.com/jeep_knowledgebase/article-46.htm I would also like to mention for peace of mind that I used these exact charts to determine what speedometer gear I needed when I put my 4.10's in with 31's and it is within 1 mph of my GPS at all speeds up to 75 mph (that's the fastest I've went with a GPS in my Jeep).
  13. eBay... seriously. It's where I got mine. Just as an example, if you've got a 4.0 with auto, 4.10 gears swapped in running 31-32" tires, you want a 37 tooth speedo gear.
  14. Never owned either of these myself, but a couple different people I know have the Dodge with the Cummins 6bt (the 5.9 you mentioned) and love them. Powerful, reliable and best of all a diesel inline 6. If you can't Dodge it, Ram it. You don't want to be Found On Road Dead... lol.
  15. Junkyard... That's the only place I've been able to find them.
  16. Believe me, I was almost about to buy a '96 XJ with 4.0 and AX15 for $700, but the guy sold it before I could get there. He had the interior stripped minus the dash. Would have made a great donor.
  17. Not sure if you are talking to me or the OP, but I plan to run a two row CSF in mine. OEM isn't worth the money...
  18. I see this term "NOS" used a lot around here.... What does it mean? Or is it some expensive aftermarket Jeep company?
  19. Hahaha, I figured I wouldn't have got so lucky. I think I'm going to just cut that section out of the MJ and my donor and weld in the piece from my donor.
  20. Some more questions as of tonight... I pulled the large collection of wires that run from the driver's side, around the front crossmember, and back up the passenger side. With that being said, that large collection of wires dead ends into the back of the fuse panel. My question is, do I remove the fuse panel and pull all those wires out to replace them all with the ones from my '90 XJ donor? Also, how do I remove the steering shaft from the steering gear box? I need to remove it as it is leaking from the pitman arm.
