02Ratings & ranges

R2.8 ratings are Cummins' published crate-engine figures; installed output depends on the build.

Equipment World reported 267 lb‑ft at the 2017 unveiling; Cummins' current page and 2018 flyer say 310 lb‑ft, and the flyer notes final ratings may vary. Expect either figure depending on the source's date.

03Where you'll find it

Makes and models we could tie to this engine family through the vehicle maker's own literature and/or NHTSA recall filings. "Years documented" means the years those sources cover. It isn't a complete production span, and not every vehicle of that model has this engine.

04Emissions eras (EGR, DPF, SCR)

Era dates are Cummins' on-highway emissions steps in North America. A given truck or bus can carry an engine built to the previous standard for a while after a change, so go by the engine dataplate, not just the model year.

  1. Crate R2.8

    Cummins says the R2.8 met EPA Tier 0/Tier 1 light-duty standards in testing, which makes it generally suitable for model-year 1999 and older light trucks and 1993 and older cars. Whether it's legal in your vehicle depends on your state; check before you buy.[1,4]

  2. ISF2.8

    Cummins lists Euro III certification for the ISF2.8; the Australian Foton Tunland's version was described as Euro 4 compliant. Diesel Hub notes it has had no U.S. on-highway application.[6,7,5]

05Common issues, in plain English

Patterns documented by the sources below, not a prediction for any one engine. Diagnose before buying parts and follow the engine and vehicle makers' service information.

Emissions legality is on the installer

Applies to R2.8 crate engine

The R2.8 is sold as non-certified. Cummins states that suitability for any particular vehicle is the installer's responsibility and that installing it where it isn't intended can break U.S. and Canadian emissions law and void the warranty.

What to watch for

  • Your state's rules for engine changes before buying.
  • The vehicle's model year against Cummins' 1999 truck / 1993 car guidance.

06Recalls & how to look them up

1. Search the vehicle. Enter the 17-character VIN at nhtsa.gov/recalls. That finds recalls filed by the vehicle maker (the truck, bus or chassis builder), such as Freightliner, Blue Bird or Nissan.[9]

2. Search the engine. Recalls Cummins files against its engines are equipment recalls. Their campaign numbers contain an "E" (for example 18E-081) and they follow the engine serial number (ESN), so they may not show up in a VIN search. On the same NHTSA page, search equipment/manufacturer for Cummins, or open a campaign number directly, then compare its build dates and part numbers with your engine. For a definite answer, give the ESN from the engine dataplate to a Cummins-authorized service location.[10,11]

3. Bulletins. TSBs for medium- and heavy-duty vehicles appear on NHTSA as manufacturer communications when the maker files them; we don't copy their text. Year/make/model shortcuts: none for crate engines; search the vehicle the engine is installed in.

Safety recalls we verified on NHTSA

We found no NHTSA recall filed against the R2.8 or ISF2.8 in North America. For a swapped vehicle, NHTSA's VIN search covers the original vehicle maker's recalls only. Each one was confirmed in NHTSA's campaign records on 2026-10-19; summaries are in our own words. It's not a complete list for any vehicle.

07Swapping an R2.8: what's in the box

Cummins' kit includes the front accessory drive (alternator, power-steering pump), vacuum pump, fuel filter/water separator, remote oil filter, ECM, starter, flywheel, accelerator pedal and a basic wiring harness with a dash display.[1,5]

You supply engine mounts, the transmission and adapter, the cooling package and, because it's turbocharged, a charge-air cooler. Cummins' page also lists the battery.[4,1]

At its 2017 SEMA debut Cummins showed R2.8s installed in a vintage Jeep and a 1980s Toyota pickup, and said 25 customer builders had done trial installs in trucks and Jeeps.[4]

An installed crate engine doesn't raise the vehicle's original payload or towing ratings, Cummins notes.[1]
