Hey Guys - Just reading up on some of the various forum posts on the web and saw this one that mentions "50 state CARB approval" a few times. I wanted to set the record straight that we (Cummins) have submitted the data needed to obtain an EO but have not received an EO yet and no guarantee on if and when that will happen. It's been almost a year since submission and it has not been rejected and those are the only two facts I can share. So before you buy, please make sure you understand your local laws!
Here's the verbiage on our site that speaks to emissions and you can use for those conversations:
The Cummins R2.8 Turbo Diesel (PN 5467036) has demonstrated through the testing procedures prescribed in 40 CFR Part 86 to meet EPA's Tier 0 (LDT 1 and 2) and Tier 1 emissions standards (LDT 2 weighing less than 4000 lb complete weight). This means that the R2.8 generally is suitable for Model Year 1999 or earlier light duty trucks. However, the suitability of the R2.8 engine to any vehicle is the responsibility of the installer and may depend on state or area laws. Installation of this part in a vehicle for which it is not intended may violate U.S. and Canadian laws and regulations related to motor vehicle emissions. Check your state and local emissions requirements before purchasing.
