4 years ago I swapped a Nissan SD-33 Nissan turbo diesel onto a YJ (Wrangler) frame, YJ body tub, CJ nose, dash, and tailgate.

The Nissan started blowing lots of blue smoke, that combined with its increasingly expensive parts, meh power, and non overdrive transmission prompted me to look into something different.

I picked up a Recon 4BT with about 60K miles, new Dodge NV4500 off ebay, and a Atlas II t-case (by the time I added a 4:1, rebuild kit, twin stick, and HD output shafts to the D300, I was nearly at the cost of an Atlas).

This site has been EXTREMELY helpful, my $20 support check went in the mail today.

Here are progress pictures.

Radiator hoses went extremely well. It is a two row universal Ford radiator <$200 on ebay.

The top hose is Autozone number 61252 (I think it is also a Goodyear number too). Fit after trimming a couple inches off the rad end. Engine side is 1.75" ID, rad 1.5" ID.


Lower hose is comprised of two hoses number 61323 is on the engine side (2.25" ID), reduced to 2"). The rad side hose is number 61252 (1.75" ID on each end).

The local plumbing shop hooked up up with a street elbow and reducer which I soldered together, BTW, copper is not cheap $21 for the two pieces.

Nice job on everything! The motor mounts are sweet!

The SD-33T that you took out used to be a good motor that would get a Land Rover 109 3-Door that belongs to a friend up to 77mph WOT on level ground. We hit 88mph once on a down hill with a tail wind and we were worried we might go back in time!

Not sure how much faster the 4BT will push you, it only has like 4hp more than the SD-33T... and like 90ft/lbs more torque :D

Can't believe how well your camera picked up the LOUD NOISE!

Thanks,
I once got my SD33 up to 80 MPH (downhill, lol), it cruised comfortably at 64MPH with 35" tires and 3.73 gearing, but was up there at something like 2,300 RPM, the NV4500 should drop that significantly.

UPDATE:

The Dodge PowerWagon clutch master was pushing too much fluid, depressing the clutch pedal only 1" disengaged the clutch and pedal pressure felt like a vehicle with non-power brakes. :eek:

I swapped in a Wilwood .750" master cyl ($50), it is nearly identical to a mid 80's CJ-7 4-cyl clutch master.

Now the pedal feels FACTORY, like a new Jeep. bounce

BTW, I am using a stock 1998 Dodge Ram slave cylinder, 1" diameter IIRC.

Questions?

Excellent pictures! A tremendous help.

How much room do you have between the rear of the Radiator and the front of the fan pulley? In inches. Looks like 6"?

How much between the firewall and rear of cylinder head?

And finally What angle (fore aft) is the drive train sitting at?

I am just about ready to install the drive train in mine, and even though I drew everything up on Computer, I am still looking for verification by someone who has been there in the real world. Randy

JP cover

Just wanted to say that I read the article in JP about you like forty-eleven times. It's what made me start researching a diesel swap for my YJ, and eventually led me here. I'm hoping to do a 4bt swap sometime in the next 2 years. I just have to figure out what I'm doing (I've never messed with diesels before), then start buying some parts. At least I've got some time to do my research. Thanks for the inspiration!!

Okay, we're WAY overdue for an update - how is this setup working for you & is there anything you'd change?
Do you like it better than the previous powerplant?

Nice build and I am glad you posted the link to this in "4bt in a jeep wrangler", I had never seen it before today. I would have never found it on JU either, it is the only Jeep site I avoid.
