    A short release with some details... The 2.8 Turbo Diesel crate engine can now be purchased exclusively at Cummins RePower.


    Cummins Repower has performed extensive work to ensure this product meets the expectations of future customers.

    The 2.8L Turbo Diesel is the first in the series of brand new crate engines that Cummins will market directly to the consumer under the Cummins Repower program name. The turbocharged 2.8L I4 is parented from a global platform which is currently used in small pickups, chassis cabs, SUVs, vans, commercial vehicles and industrial equipment around the world, but has been tailored specifically for the North American automotive aftermarket. The proven platform is an efficient and clean alternative that brings new power to vehicles with older, dirtier engines beyond their useful life.

    In addition to providing future customers with Cummins reliability and dependability, the 2.8 Turbo Diesel kit includes everything from the throttle pedal and dashboard display including all the harnesses in between. Kitting for the engines takes place in historic "Plant 1" in Columbus, Indiana.

    The R2.8 Turbo Diesel is a powerful 2.8-liter 4-cylinder engine targeted as a cleaner and more efficient alternative to many older original gasoline and diesel engines used in iconic small pickups, SUV's, and 4x4's that are beyond their useful life*. The combination of low end torque, low fuel consumption, low engine operating temperatures, modern high-pressure common rail fuel injection, and compact packaging makes the R2.8 Turbo Diesel the ideal engine to power your project wherever your adventure may take you.

    This is less expensive than I expected but also heavier than I expected.

    I'm not impressed with the Torque numbers either.
    I expected those numbers to be higher due to the 2.8 liter.

    Hell a 1995 2.3 L Turbo Volvo made the same HP and 35% less torque.
    195 ft lbs vs 267 Ft lbs

    Volvo gasoline motor makes 84.78 ft lbs per liter
    The Cummin's Diesel makes 95.35 ft lbs per liter

    Needless to say "Big Yawn" for $9,000, at $5,000 - $6,000 it might be a good engine for a gas to diesel swap.

    So for Shi*s and Giggles I looked up the specs on the Ford 2.3L Ecoboost gasoline engine that comes in the new Explorer. It gets even worse for the Cummin's Diesel.

    2.3 Liter 4 cylinder , 280 HP and 310 Ft lbs of torque.

    Need we go any farther discussing this?

    Hi Al:

    You have to forget about any gas motor with a turbo. The TD's torque is created at just above idle and a 95 I4 gas motor will probably consume probably 3Xs as much fuel at the same load.

    The R2.8 I4 Cummins TD comparison should be vs the GM 2.8L I4 TD Duramax in the Colorado and Canyon.

    GM's 2.8L Duramax outputs 181 hp and 369 lb-ft. of torque
    Cummins 2.8L outputs 161 hp and 267 lb-ft. of torque

    Regarding price, this is consumer retail. If you were to price an I4 from any OEM, they would probably come in around $5k despite being made for < $2,000. I bet an OEM could pick this I4 TD up for just $5k in quantities of 1,000 or more. A guess on my part.

    Hi Wayne,

    My point was the Hp and Torque numbers are disappointing for the Cummins 2.8 liter Diesel.
    That motor should be making much more torque for the cubic inches involved.

    I understand with the diesel, the Hp numbers are always low but on the flip side, turbo diesels usually make huge torque numbers per liter.

    This is a drop in engine for replacement on an older car. I'd put it in a '70s land Rover.

    Cummins has no idea what transmission and running gear it will be driving once it leaves the factory, and likely erred on the safe side. The end user likely can get more out of it with tuning. In an OEM application, Cummins is working with the car manufacturer, and will know the details of the transmission.

    You should see the fine print on the order page. The verbiage answered a few questions in the back of my mind...

    How much $ does it take for the equipment required to transport and scrub exhaust gasses from the 4 exhaust ports to the 50 state legal tailpipe?

    /ref Bill's comment above.... looks this would be a conversion for vehicles grandfathered in to lower emission standards... 1999 or older.
    // no 'delete kit' required,.. 'coal roll' ready... right out of the crate!

    Hi Carcus:

    I doubt Cummins would never do that. Given the lower HP and torque output, it appears they are being very conservative with this one.

    Hi Wayne,

    The coal rolling feature was tounge in cheek.. but:

    I see a LOT of 5+ year old diesel pickups that appear (judging by the amount of smoke on acceleration) to have been 'deleted' (and likely boosted beyond factory specs).

    Unfortunately, the delete mod makes economic sense once the owner has exceeded the drivetrain warranty -- eliminating many potential (and expensive) potential points of failure.

    The cost of a new Lycoming O 360, which has about 180 hp and 350 ft-lbs torque @ 2700rpm, is about $82,600 (depending on how it's configured). That's a 5.9 liter gasoline non-turbocharged carbureted engine. The high cost is why aviators look longingly at powerplants such as this. You need to come up with a prop-speed-reduction-unit for the Cummins but you could throw away the Cummins for less than the cost of an overhaul of the Lycoming. You could burn JP-5 which is cheaper and safer than avgas and widely available. Your fuel burn would be ridiculously lower than the fuel-cooled Lycoming. The deal-killer is the weight, though. The Lycoming O 360, ready to run, weighs about 350 lbs.

    I was a diesel owner for years with my first being a 1977 VW Rabbit diesel, and later 3 other VW Diesels Turbo charged. However, I have little interest these days. Diesel here in this neck of the woods is $2.879 / gal. 87 octane is $2.499 / gal. Also the added cost of Urea injection in the new diesels and all that extra "stuff" makes the new diesels prone to mechanical / electrical issues which may cost you dearly once the warranty expires.

    Back in the day when I purchased my 77 Rabbit diesel, diesel was far less money per gallon than regular gas, and 50 + mpg was easy to obtain as well, there was no diesel shortage, and it ran just as well on #2 Fuel Oil, or Heating Oil. It was a win for me as the diesel option was only $170.00 or so over the gasoline engine.

    I'm quite happy with our 2010 Prius and 2016 Volt over any VW diesel that probably would be available if it was not for "dieselgate".

    Among some of the commercial truck segments, emission requirements are tied to the engine. It is a common practice for semis to buy a new glider, and install an older, rebuilt engine in it to avoid current emission controls. That loop hole is suppose to be closed soon.

    For Pa passenger cars, an engine for a swap can not be of a model year older than the frame's.
    I now know my second purchase after the Tesla once I win the lotto.

    No way is this a DROP IN ENGINE- right??

    Which vehicles will it actually DROP IN??

    Guessing no way my 1998 Suburban-but that would be pointless since my 5.7 gets "not horrible for 20 year old HUGE SUV" mpg
    and it still runs-234,000 miles-despite my allowing it to lose coolant-blow it past gaskets("repaired" with leak seal") and other owner induced screw ups-yeah it is an owner proof vehicle

    But bet it would fit in various RAMS??
    In the mid 1980's full sized pickups had just 150 -170 hp
    Pretty sure GMs 350 diesel-in suburbans and pickups- made just 150 hp-no turbo-and numerous "problems"
    but great mpg for the time

    A drop in Goodwrench-5.7 for my truck-$2300 dropped at curb
