TDI

 Ken Brubaker (an editor over at Four Wheeler magazine same team as Diesel Power) wrote a number of great articles about diesel. One was called, "14 Companies that Specialize in Diesel Conversions."  Who wouldn't want a TDI powered Jeep? Here is another cool diesel article from Four Wheeler, "4BT Cummins 1984 GMC Jimmy: Mechanical Engineering."And Flashback: Dodge Ram 50 Turbodiesel here's a quote,

How did they do on fuel efficiency with the Ram 50? Well, pretty darn good it seems. In this ad, the four-wheel-drive turbodiesel had an EPA rating of 40 mpg highway. With 40 mpg and an 18-gallon fuel tank the Ram 50 would’ve had a cruising range of 720 miles. That’s pretty impressive.

This Ram 50 ad got us thinking about how cool it would be, now that fuel prices are climbing to absurd levels here in 2012, if the manufacturers offered a compact pickup powered by an economical turbodiesel engine. It would be dandy if buyers had the option of a body-on-frame, diesel-powered, small pickup truck that gets 40 mpg. Heck, even 35 mpg would be welcome. We hope that a pickup truck like this is in our future. After all, there’s already one in our past.

Do you drool over diesels? Well, if you’d like to convert your gas-powered rig to diesel power, there are actually a surprising number of companies that specialize in these conversions. Some offer problem-solving parts and kits, others offer complete in-house conversions, and a few offer the whole enchilada with parts, kits, and the option of a complete in-house conversion.

Following is a list of companies that can help you complete a diesel conversion. We’ve tried to include companies that cover a wide range of makes and models of trucks. Some of the engine swaps are mainstream, while others use the less prevalent Toyota, Mercedes-Benz, and Volkswagen diesel engines.

So if you’re in the market to go diesel, start here.

Bruiser Conversions
Getting a Cummins 4BT in your Jeep CJ, YJ, TJ, or JK is as easy as dropping your rig off at Bruiser Conversions. You can choose from two automatic transmissions and one manual transmission. If you wish to complete the conversion, the company offers components to install a 4BT into your CJ, YJ, or TJ. There are a slew of upgrades available as well.

Mash Motors
How about Duramax LBZ power under the hood of your Hummer H1, H2, or large GM SUV? Well, Mash Motors can make it happen. The in-house conversion includes an Allison M1000 heavy-duty six-speed automatic transmission, two-speed part-time transfer case, Duramax wiring harness, modified ECM, custom 4-inch-diameter exhaust, and much more. Performance upgrades include a head stud kit, 60 psi turbo, power programmers, water injection, propane injection, high-flow fuel injectors, and more. Mash Motors says build time is approximately 45 days for a H1 and 25 days for the H2.

HPA Motorsports
Got a Jeep YJ or TJ? If you’d like the benefits of a Volkswagen TDI engine you can either purchase one of HPA Motorsports do-it-yourself kits or you can let the company complete the conversion in-house. The DIY kits are available in two stages. Stage 1 is a bare bones grouping that is intended for those who wish to take on the fabrication and plumbing of the TDI’s boost track, gas pedal fitment, and so on, and have the resources available to tune the engine software around their final configuration. Stage 2 builds on the Stage 1 package, adding the engineered air-to-water intercooling system, a performance ECU tune that has reconfigured the injection around the ultra-efficient boost track, a bracket for the gas pedal fitment, and key coolant line fittings to better facilitate the Volkswagen cooling system. HPA mates the VW turbodiesel engine to specific manual transmissions and the company is developing a kit to install the engine in the Jeep JK.

Proffitts Cruisers
Got a Land Cruiser? Proffitts Cruisers can perform an in-house conversion to the 3.3L Cummins, 3.9L Cummins, or a Toyota turbodiesel engine. The company says it has installed over 70 4BT conversions into a variety of Land Cruisers. When it comes to Toyota turbodiesel engines Proffitts says the most common engines used in its conversions are the six-cylinder variants offered from 1986-up, which are the 12HT, 1HZ, 1HDT, 1HD-FT, and the computer-controlled 1HD-FTE. Pictured here is a ’94 FZJ80 Land Cruiser fitted with the 1HD-FT Toyota six-cylinder diesel engine mated to a five-speed manual transmission. The company says this is the most complicated conversion it performs because the donor vehicle is right-hand-drive and it takes over 50 hours to mate the wiring harness to the left-hand-drive harness.

Domino Effect
If you convert your rig to diesel and the power output is increased over your previous powerplant, you may have to beef your rigs driveline. There are many variables to this of course, depending on which diesel engine you’ve installed and whether or not you’ve already made driveline upgrades.

We wondered how the OE manufacturers approached this increase in power, so we contacted Chrysler and asked about the driveline differences between a gas-powered ’12 Ram 2500 and a diesel-powered Ram 2500. The Cummins turbodiesel makes 800 lb-ft of torque, which is double the torque of the Hemi V-8. The diesel-powered Ram gets a beefier 68RFE six-speed automatic transmission, but uses the same transfer cases (manual- or electric-shift) as the gas-powered trucks. The driveshaft U-joints in the diesel-powered Ram 2500 are larger 1485 series ’joints as opposed to the 1415 series ’joints found in the gas-powered trucks. Finally, the diesel-powered rig is equipped with an 11.5-inch rearend, which has a higher torque capacity than the 10.5-inch rearend in the gas-powered truck
