Topic: Would dig a diesel

[chrisfranklin]

If I hold on to this Jeep long enough, I am going to seriously consider a cummins turbo diesel swap, some kind of auto tranny and some decent axles, etc. etc. Tire size and lift, who knows?   Of course, by the time I get to that point, Jeep will probably have already introduced a Diesel Wrangler.  That will begin to cloud my judgement finding the shortest way to driving a Diesel Wrangler

a cumins in a wrangler would be really heavy... thats the only draw back i can find

[oldjeep]

4BT swap has been done a few times, even that is pretty heavy.  A 6BT is insanely heavy for a jeep sized vehicle.

I would think a small 4cyl diesel from a VW would work out well. The VW diesel is an option for Sami's so why not a Wrangler. Add an intercooler and a turbo for better performance. Another option could be a 4cyl diesel from a manufacturer like Perkins. They are installed in a lot of military tow vehicles for the tarmac as well as the public airport transport vehicles. What the diesels that are marine based?

I've brought this up in past threads.  The biggest problem is that you're in CA and getting a diesel conversion might be dependent on how up on the laws the local DMV is.  The other problem would be to find an engine that is no older then your Jeep.  That means anything older is out.

A Cummin's I6 would be WAY too big and heavy.  A 4BT has been done but it's not even a passenger car/truck engine.  It's also a bit tall so you'd need a body lift.

Other options would be a Import diesel.  2.5L Peugeot was the official export Jeep engine during the 90's.  It came as a Turbo with something like 115hp and 254ft-lbs of torque.

I've thought about a import Toyota or Mitsubishi diesel, too.  The only consideration to make is if you want it to run old school with no PCM or with one.  If I was doing the install, I'd defiantly go without.  It's a lot easier to swap in an engine that doesn't require any wiring.  Not to mention water will be less of a problem.

How about the 2.7L CRD in the Liberty the past few years?
There's also the new 3.0L CRD turbodiesel in the 2007 Grands, 215 HP @ 3,800rpm, 376 lb-ft of torque beetween 1600-2,800rpm.
The new 3.0 should meet all emission standards

Cost would be expensive since the 3.0L is all new.  It's a bit untested and parts availability would be limited at first, too.  Since it's computer controlled you'd have to make sure the PCM is all wired up and gets all of it's sensors working and in the right places.  You'd also need to splice the hold harness with the new one.  This is why I was looking to go with a stand alone engine that doesn't need a brain.  Simpler to setup and run.  Only problem is getting it all past a Ref or if your lucky transfer from gas to diesel without inspection.  (this seems to be what the Toyota guy's are doing.)

BTW: Diesels don't go through CA SMOG.

gotta love the old diesels were after you get it started you don't even need a battery.

Was looking at this site.  Not too many diesel options listed. 

The Volvo diesels I am aware of were said to be pretty unreliable 
Mercedes TD in a Jeep

They show the 4BT Cummins engine in a CJ. 

I'd be ok with the liberty CRD, because it makes decent torque.   But if I am swapping engines I'd really only want to do it once and go as large as possible.

   You really need to see one in person.  Diesels are big by nature.  The 4BT is a big boy at 750lbs.



Going with an Import engine would make it a bit lighter and be a passenger car application and not heavy equipment.  4Bt's are used with pumps and generators.

I think in time the engine out of the Dodge sprinter will make a nice clean running diesel engine that is certified for California. It is not heavy runs very clean has pretty good power, nor is it very big. Will take some moding for the fuel line cooler near the tank lots of electronics but will make a nice conversion
