1979WagoneerLTD I have manufactured the hardware components for the conversion to my own specification, as noted in this build thread and the MKII TDI thread. I like to build my own, so what is made stays here for whatever build comes into the shop.

mehbohdi Am I to understand (After reading almost all of this thread), that your are creating a kit that will be for sale or just the knowledge to put this all together? Or a little of both. I,m more of the opinion, buy a donor vehicle and start from there. The COTY kit seems like a lot $$. I can buy alot of gas for $5-6000. Don't get me wrong I like diesels, I drive a Dodge Cummins P/U every day. I'm just saying. Great write up, thanks for taking time to post all this info.

You have mentioned doing a conversion on a 2.0L TDI as well? This is what I am looking at putting in my 1999 TJ. I am hoping to find the same type of engine thats in my 2009 VW TDI jetta. Have you been looking to do a 20. swap as well?
I'm working of that now; the adapter system I designed is built around the 2.0, but can be fitted to the earlier engines. We actually bought a 13 Jetta TDI to double as a daily driver and lab rat! I

SIDEBAR: I HIGHLY RECOMMEND VW instructional course by Automotive Training Group. Although designed for site instruction, the text and DVD can be bought from them. Another tool that was invaluable (and a great diagnostic tool anyway) is the 16-pin datalink connector breakout box.

The whole Jeep is getting a pretty radical transformation.

These engines have a vacuum pump on the back if the head that is camshaft driven. With the BEW/BRM, it's a tandem pump assembly, both fuel and vacuum pump. All you have to do is connect the jeep brake booster and HVAC vacuum line in the same way as the gas engine.

The NV3550 is a proven transmission, and a safe bet. The six speed has mixed reviews for reliability, I don't have enough information to make a judgement. I will be using the six speed with the 2.0; if it explodes, it'll likely be that I screwed up (not uncommon).

The BEW/BRM is a fine engine with great potential. Problem is availability now and in the future; I believe that the current C engine is a more logical choice because it is much more common in the US/Canada.

So yeah, when you're ready, I'm hoping to have my original Green Jeep fitted with the new engine, conversion system, and other details that'll make it viable and proof the concept.

In respect to reliability, the c engine is not some radical departure for diesel technology; nothing about it is revolutionary outside of popularity and sales. The fuel injection system is Bosch "common rail", using a high pressure pump, pressure accumulating vessel "rail", and piezo-injectors for multiple shots of fuel. Iron block, aluminum head, steel innards, giant EGR cooler...Duramax is not much different (or Cummins for that matter). It's quieter than the 1.9, with a strong bottom end. Pound for pound, these TDI's are the most powerful small diesels you can get.

Fuel economy is increased. Ability of the diesel to lug through high-gear conditions expected steep highway grades, for example, is impressive when compared to the 4.0. The ability of the engine to maintain a steady idle while crawling is unmatched. Other diesel-over-mogas virtues is up to the individual to decide.

The rear Dana 35 was swapped for a TJ Dana 44 with Powr-Lock. The front 30 is open and unchanged.

Performance is comparable with a 4.0 five-speed stock TJ.

1979WagoneerLTD The first TJ was a stock SE 2000. It used the AX5, 21 spline NP231 syo. It has traveled over 8k miles, most of it being driven hard, with no drivetrain failures.

Although this setup has been trouble free, the AX5 is still a light duty transmission that is less robust than the 15 or later TJ manual transmissions. Therefore, I avoid the AX5 for future conversions.

I have no intention of using the BEW/BRM engine again unless it's requested specifically; good rule of thumb is 8-15k for the TJ, 3k for the engine, 3k for the conversion hardware, and labor.

They are Golden Eagle edition wheels that came with the 2006 TJ of the same edition. They are otherwise the same as the standard Ravine wheel.

1979WagoneerLTD I forgot that someone awhile back asked about the seats. The stock Sport seats were shot, so I went with the BesTop buckets that look similar to stock. They're ok for casual driving but don't offer much bolstering. The fabric, however, is tough and cleans easily.

They were off of a Golden Eagle edition TJ, 2006 I think. Random Craigslist ad that popped up one Sunday morning, with the guy being a couple miles away in Rancho Bernardo. I think I gave 250 or 350 for all 5.
