Diesel Conversions
« on: June 18, 2007, 02:47:33 PM »
Well, I've been talking to the Bureau of Automotive Repair (BAR) and I still have many questions.  But so far things look promising.

"A few things you must remember. First the diesel engine must have
California emissions certification and it must be for on road use- no
commercial or industrial applications. Then the engine must be the same
year as the chassis or newer and the engine must have all required emission
components installed and operational. DMV may require an inspection at the
BAR referee to document the vehicles condition before registration but that
is up to them."

So this does give hope to a Gas-to-Diesel engine conversion.

that is good news, if only diesel were cheap here like in the old days... I think you should post up some common diesel motors used for swapping into our jeeps in this thread.  :thumbsup:

Not yet.  It's export only right now.

Here we only get the 2.8 turbo diesel for the sport and unlimited model (only ones available through dealership). Are the engine mounts the same? Besides the bell housing could the engine be plug & play?

No, it was a mistake by a Magazine Editor.  I've heard second had from the Engineer in charge of such projects that there is no conversion planned.

I doubt it would be plug and play.  I'm going to bet that 2.8L diesel is the Mercedez diesel used on their small commercial trucks.  My dad had the non-turbo version of those engines in his '91 Land Cruiser in Brazil.  They have a bunch of power... against that engine the AX-5 would litterally explode.

The local junk yard just took in an 85 volvo with the 2.4 turbo.  I haven't heard it run yet, but I guess the guy drove it there, so it can't be too terrible.  I was given a price of 250 bucks for the whole engine and manual transmission bellhousing.  I am wondering if you guys know anything about this swap.  I have seen online that one guy switched to a t18 tranny, without much trouble.  If I switched to this tranny as well, what would I use as a transfer case or can I keep my np231 where it is to prevent a big driveshaft project.  I'm looking for any ideas you may have regarding this swap and if its even worth it.

Well I pick up my diesel engine today.  Its a D24T.  I could actually start the engine up and here it run.  The turbo has no shaft play, didn't notice any blow by, so it should be a pretty good motor.  The plan is to make a fake jeep frame, out of 4x4's, mount the engine to it, and put it to the test.  I'll mock up the ax5 to it, and fab an adapter plate like in the link below.  Once I'm sure it's ready to go, then I'll put it in my jeep.  I'm sure there will be challenges, but it seems very straightforward.  Even the clutch disk sizes match.  My only concern is the strength of the ax5, but I don't have very large tires, and this motor isn't insane when it comes to torque, so it should be ok.  If not, well, I'll cross that bridge later.  BTW, does anyone have an old ax5 they no longer need?  As long as the input shaft turns, I don't care how messed up the rest of it is...
