diesel story: 81 CJ 2.5td

This is my CJ converted to diesel. Discussion on engine conversion is at CJ7 with Jeep diesel. I started with frame-off restoration, there was just too much rust on tubing, frame and fenders. Besides diesel conversion I did other modifications to this jeep.

- 4" lift, HD shackles
- front twin shocks
- ax15 with twin stick dana 300
- cv rear driveshaft
- hand controlled parking brake
- frame reinforcement
- custom front and rear bumper
- custom fibreglass hard top (still in progress)

Nice, but why not mount the intercooler in front of the radiator?
And where do you live in nova??

Space for 8274 needed there
Relocated IC further to the front. Originally had it below the radiator but it was hitting the steering linkage. I used to live in nova now I am overseas should update my profile...

Is there any trick how to add more than 5 photos without paying for subscription?

I just love the sound of the 2.5TD, too bad they are infamous for being low quality engines.

manual needed

Hello,
I'm new around here and I'm very glad to found you. I have a C7J with a diesel VM engine. I don't know nothing about the type of the engine and I need to put the water, turbo, intercooler and vacuum hoses. Turbo and intercooler is quite simple, but with the others I have a problem. If you can help me with some pictures, informations or a service manual will be great.

Thx,
Andy

the 2nd pic is deceiving, it looks like your intercooler is hanging below the front axle tube. how much clearance do you actually have? are you going to fab a skid to protect the bottom end of it?

It is higher than front differential. I agree some reinfocement towards rear would help. I took her to several 4x4 gatherings and the intercooler is still intact.

By the way this engine is far from overheating. I have never exceeded 160F and july was pretty warm in here, nearly as warm as Texas in June. I am using two mechanical temp gauges to be sure. I got rid of expansion tank and used a cooler thermostat (opening at I guess 73? C). I have no idea what people could do with their cherokees to overheat their engines.

The only issue that remains is that I want to hook chrysler SBEC controller to manage the injection timing to smoothen the engine run. However I cannot find the wiring scheme for diesel SBEC. It is totally different from gas unit.

edit: I don't know much about vacuum. You have a vacuum pump in front of alternator. I just connected hose to brake booster. make sure you get rid of EGR (that also uses vacuum to move EGR valve)

I have connected the EGR valve to the brake( Pazur's blue hose). Is it ok? But I need some electrical diagram for the VM diesel engine. Can somebody help me?
