Diesel Conversion Needs

The questions we usually have when going to pull off a diesel conversion is to start off with matching an engine’s power output to a project’s needs. That’s one of the most fun parts as it’s usually accompanied with a bit of bench racing and dreams of how the project will perform in the end (be it a boat, hot rod, pickup or bar stool racer). After that, question’s trend towards “Will it fit?” or “Is it possible to pull off?” Sheetmetal can almost always be trimmed, massaged or removed all together to create clearance when needed. It’s obstacles like electronics or adapting an engine to an existing transmission that usually are the most common things holding a project back. If only there were a diesel conversion kit for every diesel swap possible.

Luckily, thanks to the automotive aftermarket, there’s help as conversion parts do exist. Tons of them! We’ve put together a small list of diesel conversion-specific products as well as a massive list of vendors who can help you swap a diesel into your ride. We’ve also gone back through the archives and picked our favourite, top 10 diesel converted rigs from the past few years. Hopefully, this will give you a bit of motivation and info to make you a diesel conversion specialist and get that project rolling into the diesel world

Black Beauty

This Duramax Powered street/strip truck is owned by Brett Deutsch. His grandfather gifted this 1969 Chevy C10 for his 15th birthday. Brett’s grandfather had performed a Detroit diesel pickup conversion utilizing a three-cylinder Detroit Diesel engine, but the power was underwhelming. To satisfy his need for power, a swap to a small block Chevy gasser was installed but proved to be lacking too. Today, this truck is a Duramax diesel powered daily driver that can burn down the strip in the mid to low 9-second slot.

Diesel Muscle Car

Rick Fletes loves power and is a real car enthusiast. He loves Detroit Iron and going fast on the track. Being a practical type, Rick knew that for less money than it would cost for a full blown Big Block Chevy gas motor, he could swap in a Duramax diesel. The diesel surely would offer more torque and be more reliable than a full race big block gas race engine ever would be.

Rick located a wrecked GM truck with a low mile LB7 and scavenged the harness and engine for his race ready, diesel powered, daily driver. With the Duramax backed by a Turbo 400 automatic and Gear Vendors Overdrive, this oil burning Chevelle turns in top track speeds around 150 mph, with ET times in the mid ‘11s. During the week, this daily driver gets between 25-30 mpg.

Cummins Powered Classic Power Wagon

Strength, reliability and simplicity—that’s the way pickups used to be made. Trucks were made for work, not comfort. Vintage pickups are enjoying a resurgence in popularity, and Brian Wellman of Crandall, Indiana, is the enthusiastic owner of a very unique, classic Dodge

While it was acquired in the rough, this W200 Dodge Crew Cab was restored to a near-new condition. The major upgrade was the swap to a 1993 12-valve Cummins. The diesel is mated to a ’92 A518 overdrive automatic and a divorced mount 205 T-case splits the power to both axles on this 4×4.

The 1948 Fat Fender F3 Ford pickup is a classic. While unique in and of itself, owner Andrew Derdok wanted something extra special for his restoration. That special touch is the diesel engine swap, a 5.9L 12-valve Cummins under the hood. The diesel is backed by a Dodge 727 automatic; and 3.07 “road gears” let this truck cruise down the road at the posted highway speeds with ease

The original plan was to make this truck a daily driver and function as a true truck to carry a dirt bike and other toys in the back.  That plan changed, of course, when the finished rig was show quality.

The owner of this red racer, Dustin Hamm from Sebastopol, California, acquired this 1967 Camaro when he was just 16 years old. It came to him with a 600-hp small-block Chevy gasser V-8. The trouble was, the power came at a cost. The cost of getting just 8 miles per gallon was seen at every single fill-up.

In 2009, Hamm decided to swap in a LBZ Duramax diesel. This was swapped into the Camaro, with a 47RH automatic from a Dodge diesel truck. The Camaro now gets 25-30 mph around town and turns in 13.0 ETs at around 110 mph on the track

David Chader was a car guy from a young age. At 11, he convinced his parents to buy the 1979 Jeep Cherokee Chief from a neighbor. During his senior year of high school, David and his dad decided to perform some “mild” modification to the Jeep. This included swapping in a Cummins 6BTA to replace the original AMC 360 gas engine.  The 6BTA had recently been rebuilt, and it was treated to some upgrades before being slipped into the Jeep. A SunCoast 1994 47RH automatic transmission sends power to the transfer case and then splits out to the front and rear Dana 44 axles. The Cummins allows David’s mighty Cherokee Chief to average 25 mpg during extended travels all while not missing a single beat.

1929 Model A Oil Burner

It has become an urban myth that when Henry Ford introduced the Model T, it was available in any color you wanted, as long as it was black. This isn’t true, but the fact that neither the Model T nor late Model A where available with a diesel engine is.  Cirius Noble is the owner of this fine 1929 Model A and it does have a diesel. A 2.1L (128 ci) I4 Renault diesel from a ’89 Jeep Cherokee was swapped into the Ford. This engine has an aluminum block and weighs only two-thirds of the original cast iron Ford gasser. It also has more than double the horsepower and gets better mileage too.

Rat Rods are a breed of their own. These patina’d rigs are rusty and rustic on purpose, and their owners are often as unique as their rigs. Harvey Grant is one of these unique car/rod fanatics, and his Rusty Rose is one of a kind. A 1951 Chevy truck cab, 1950 bed, 1947 grille are all blended into the body for this Rat Rod. The drive train is out of a 1993 Dodge pickup. The 12-valve Cummins 5.7L diesel has been modified with twin stock turbos and other upgrades. While not technically an engine swap, it’s more of a custom build. This diesel rig is unique and shows just how wild you can get with your truck, if you let your imagination run wild too.

ATS 4R100 to Cummins Adaptor Kit

This kit from ATS Diesel is quickly becoming popular with the late model Cummins crowd due to the problematic 68RFE transmission. Using ATS’s kit allows Cummins owners to swap in a much stronger 4R100 trans, but also helps Ford owners swap in a Cummins with their existing 4R100 backing it up.

Motor Mounts

Diesel Conversion Specialist has moved engine mount design up a notch with laser cut and CNC formed mounts, available for any year Ford-Cummins conversion project you have in mind.

PMF 2011-13 Ford F-250/350 Transfer Case Indexing Plate

When taking on an engine swap, the entire driveline must be taken into consideration. Often times the transfer case on a 4×4 model just won’t be in the proper position for your swap to go smoothly. This can often be corrected by clocking the T-case into a different position of rotation. This CNC-machined transfer case indexing plate and cross member allows the user to index or rotate the transfer case downward to correct the driveline angle on large lifted applications.  While designed for the 2011-13 Ford F-250/350, it can also be considered for the task of clocking the T-case on your diesel swap when using the Ford driveline.
