At the 2016 SEMA Show, Steve Roberts from Advance Adapters and Stephen “Steve” Sanders of Cummins Repower program share in-depth details on the Cummins 2.8L diesel crate engine conversion. Tailored for Jeep®, Land Cruisers, Land Rovers, light trucks and other swaps, the high-tech R2.8L common rail diesel (CRD) is a potent, fuel efficient, self-contained “crate” solution for maximum torque output and reliability.
The Cummins P/N 5467046 complete crate engine package is now available. Initially, Cummins will market these engines from the Cummins Repower website. Following the sale of 500 engines, dealers like Advance Adapters will be on board for direct sale of engines and adapter packages. For details on installation developments, contact Advance Adapters at http://www.AdvanceAdapters.com or phone the Advance Adapters tech support line at 1-800-350-2223.
At the Cummins Repower site, see the footnotes regarding current Federal and local emissions legality status. At launch, the $8,999 MSRP includes the complete engine and accessories package as itemized at the Cummins Repower site. Available transmission adapters, motor mount kits and other installation components are sold separately at Advance Adapters.

Updates: On November 2, 2017, 4WD Mechanix Magazine interviewed Steve Sanders at the Cummin Repower booth, 2017 SEMA Show. Steve updated us with in-depth details on installing this engine and the latest developments around the Cummins launch of the R2.8L diesel crate engine. After reviewing the article and video coverage (below), see our in-depth video update interview at: https://www.4wdmechanix.com/2017-sema-show-updates-on-the-cummins-r2-8l-diesel-crate-engine/.
The Cummins R2.8L four-cylinder diesel crate engine package is now available…Up-to-date pricing is posted at the Cummins Repower site!
Cummins is a globally respected builder of industrial, commercial (medium-duty and heavy-duty trucks) plus light-duty diesel engines. The Cummins Repower program now enables Jeep® owners and other 4×4 enthusiasts to join the Cummins family! The venerable ‘ISB’ engines, like the 5.9L 24-valve CRD in the magazine’s ’05 Ram 3500 4×4, are a testimony to the rugged reliability and efficiency of Cummins engines. The newer generation 5.0L V-8 Nissan Titan and R2.8L four take Cummins power to the next level. This Cummins R2.8L power has been used in Brazilian Ford F350 trucks. It has been beta tested in a Nissan Frontier concept truck plus media and fabrication shop vehicles. The engine is now on sale and available to Jeep®, Land Cruiser, Land Rover and other 4×4 enthusiasts!
The R2.8L four-cylinder inline common rail diesel (electronic injector CRD) is now offered as a “crate engine” for ease of installation. The package includes important details like the ECM, a wiring harness and other “turn-key” features. Run-ready Repower engines are a Cummins specialty, the company sells complete, “crate” powerplants across the globe.
Turbocharging is integral to the engine. The package comes complete with the starter assembly, alternator and provision for engine driven accessories. Advance Adapters’ precision transmission adapters and motor mount kits complement the legendary Cummins reliability in this contemporary,”clean” technology.
Chassis, brakes and A/C often require vacuum, whether a brake booster, A/C controls or a Jeep YJ Wrangler front axle disconnect. Unlike gasoline engines, a diesel engine does not produce manifold vacuum. At right, the Cummins R2.8L engine’s vacuum pump is camshaft driven, providing the necessary vacuum for chassis/body devices.
The engine comes with a finned cooler and fittings for remotely mounting the oil filter. 4x4s with a driver’s side drop front driveline could place a risk on an engine-mounted oil filter. (Older Jeep® inline sixes have a history of puncturing oil filter canisters along rugged trails.) Cummins provides fittings for the remote oil filter.
Though “busy”, everything fits neatly in the Jeep® TJ Wrangler installation at left. (See additional installations in 4WD Mechanix Magazine’s 2017 SEMA Show interview video!) On this installation, the remote oil filter mounts near the brake master cylinder/booster assembly. At right, the front of the crate engine provides easier adaptation of engine driven accessories. Cummins crates this R2.8L Repower engine with a new alternator, common 8-rib belt pulleys, the belt tensioner and a universal bracket for the A/C compressor. A new power steering pump (not shown here) is also included in the package.
Fully operational and featuring the vehicle’s original functionality, the R2.8L nestles neatly in this Jeep® TJ Wrangler engine bay. The stock 4.0L radiator is able to handle the rated 161 horsepower and 267 ft-lbs of torque, claiming an operating temperature of 177-180 degrees F. The precision machining on the Advance Adapters engine-to-transmission adapter assures a proper fit. Currently, the transmission adapter lineup fits the Ax15/NV3550 and G.M. automatics. Discussion is underway around fitting the Aisin AW4/A340 transmissions. The AW4 automatic transmission is common to both Jeep® XJ Cherokee and Toyota truck applications.
The initial launch from Advance Adapters will include several Jeep® engine mount kits and transmission adapters that include the Jeep® AX15/NV3550 and G.M. automatics. The Cummins proposed target is a 50-State legal, California (C.A.R.B.) E.O. certified crate engine, initially for models through 1999 and including the Jeep® CJ, YJ and TJ Wrangler plus the XJ Cherokee. See the Cummins website and updates for emissions legality details.
The certification goal for the R2.8L Cummins diesel will be Tier 1 emissions standards for a run-ready crate engine. Steve Sanders goes into the actual installation details in our 2017 SEMA Show interview. According to Cummins, by design this engine is capable of meeting later, higher tier requirements and should eventually qualify for later vehicle applications like the Jeep® JK Wrangler.
As an application, the magazine’s 1999 Jeep® XJ Cherokee fits Tier 1 and would be emissions legal for a ‘how-to’ installation of the Cummins R2.8L diesel when Cummins secures a California E.O. number. Expect updates on emissions legality for this engine. Once 50-State legal, an R2.8L diesel swap into the magazine’s XJ Cherokee would be a consideration. The step-by-step process would be covered in HD video at the magazine…Stay tuned, we’ll see what develops!

Footnote/Cautions: Be aware that any engine conversion of this kind requires fabrication work and a knowledge of vehicle engine, transmission, electrical, driveline and chassis systems. A simplified outline of this kind of project includes but is not limited to:
1) Fabrication of frame mounts, the air conditioning compressor pedestal and any power steering pump/hose requirements.
2) Meeting the engine cooling (radiator and hose) requirements plus fabricating (or subletting) the exhaust system work.
3) An electrical wiring interface with the OEM ignition/starter switch, the gauge senders and any computer or onboard diagnostics. Starter and alternator wiring must interface with the chassis and gauge needs.
4) Safe and suitable fuel pump lines from the tank, a return fuel line to the tank if required, a safe and emissions legal evaporative system, and any electrical circuits related to fuel flow or fuel gauge readout will be part of the project.
5) Exhaust system fabrication and miscellaneous mate-up work related to the vehicle’s chassis, your transmission choice, and the vehicle’s driveline, ABS and speed sensor needs.
Minimally, if you do not have a full knowledge of your vehicle’s electrical and electronic needs or requirements, or if you do not have proficient welding and cutting skills for fabricating mounts and brackets, you will be subletting these chores to a qualified fabrication shop. There is no “complete bolt-in kit” or plug-and-play chassis wiring harness currently available for installing the R2.8L Cummins diesel into a specific vehicle make and model. Consult Advance Adapters for details on how to best approach this project and the adaptation components now available—and those under development.
