Welcome to my build. 1987 Jeep Comanche. 2WD in pretty good condition. Picked it up late 2 years ago and daily drove it for a while. Stopped driving it daily since I actually didn’t drive anywhere (military and can literally walk everywhere) so took it home and put it in the shop. These pictures show the condition it was in. Also picked up a New Beetle with an ALH TDI to swap in some day. IMG_5905.MOV

Mid swap. Doing the Cummins 3.3 gonna run compounds new to the forums tho I’ve read a ton of them. Might get some answers and might help someone else. Gonna keep up with progress here. This MJ has been my favorite vehicle for years. The 4.0 was well worn and did her job. On to bigger things!

1986 Jeep Comanche Long bed. Originally Equipped with a 2.1TD Renault mated to an AX5 transmission as a 2wd truck. Unsure of the rear axle. The truck is now equipped with a 1.9 liter Volkswagen Diesel engine out of a 97 VW Jetta or Passat mated to a AX15 transmission, still as a two wheel drive truck. The factory door has been replaced and the build sticker is ineligible. I am the current owner of this MJ located in the sunny Murrieta, CA. The truck is currently going through its 2nd make over (that i know of, grandpa {johnj92131 was my grandpa and owner before i} funded the TDI swap for his own project and had his own desires with the truck). Currently it is getting the head rebuilt, head studs to handle MORE boost, and getting the engine bay re done to be more cosmetically pleasing. Getting rid of the clutter and making it look like a shaved engine bay with minimal wiring exposed, the fuel and oil lines are now going to be AN lines so they can be clutter free. Otherwise, the truck is still road worthy and currently registered in Ca as a clean truck that is legal. The Idea for the truck is to get a small lift, to get the weight of the truck up a little and make a wider stance. id like to use the diesel to flat tow my XJ out on long trips. At some point the truck will be fully restored, and painted. I will be experimenting with Megasquirt and a Racepack to see if i can get the TDI to communicate on a full stand alone ECU, if successful it will bring the truck into 2021 technology. Another mod that will hopefully come in the future would be converting from AX15 to a NSG370 for the 6 speed aspect and better gearing for a diesel

Posting to tech from Vendors at Pete's request: Hello all, I wanted to post about this guy: Doomsday Diesel Doomsday Diesel Facebook Page That company is owned by a gentleman named Joe Peterson. One man show. His primary business was swapping diesels into Toyota's but he's been talked into making some Jeep adapters. I removed the kit i purchased from another vendor in favor of his kit. It is worth every penny. If you're considering installing an OM617 this is the guy to go to. * Note: I am not associated with Doomsday, my experience has been that they make great product & have great customer service. Worth sharing!

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
