Cummins 2.8L diesel on sale...who wants to be the first?

[rkymtnman]

I hope you are correct regarding Colorado. I spent quite a bit of time researching it and it was absolutely ridiculous the amount of BS and red tape I had to weed through to be told I was SOL because of the issues Octane brings up. The VIN on the FJ80 was for a gas motor and in lieu of *any* diesel FJ80 "specs" in the US market, they couldn't pass it regardless of systems and actual cleanliness.

I would love more than anything to be wrong on this one...I'd probably buy another FJ80 and get to work

Out of curiosity, why scrap the VW project? Sounds pretty bad ass!

I'm somewhat close with the main supervisor over at the diesel technical station here in Denver, and the rules, as I understand are this:

- No cross classing (can't put truck engine in car, for example)
- Engine must be newer than car that's receiving it
- All emission controls must be intact. Cat, OBD ports, O2 sensors, CEL, EPA certs, etc etc.
- Engine must be originally a road going engine. No generator or tractor transplants.

I already had official sign-off for my TDI project long before I scrapped it. This was a 1999 Toyota 4runner receiving a 2005 VW TDI motor. All emission controls and certs were to be transferred. Would have been 100% street legal here in Colorado. In fact, I've heard Colorado's emission laws are stricter than CA, and I would anticipate no issues whatsoever titling the above vehicle in the state of CA.

Cross classing is just "light" vs. "heavy" - so, that part is easy. Car engines can go is light trucks and vice-versa.

You can't go gas to diesel or the reverse though...

What I have thought of for California though: Do a natural gas conversion - get it inspected. Boom, no more smog checks after that. Then go hog wild with whatever project you want.

Maybe it's different in your state, but the director of the diesel technical center here includes truck > car as cross-classing. You are right, you also can't put heavy into light duty. I.E. no semi motors into f250s. You can actually go diesel to gas in Colorado, provided you meet the aforementioned requirements.

His goal is to closely mirror (but not 100% copy) the EPA regs regarding engine swaps.

There is a clear authority on this subject within Colorado. The Denver emissions technical center. Don't trust what I, or any other non-authority on this board says. Go right to the source. They are very friendly, and willing to work with citizens.

Depends on who does the inspection, because they can fail you on the visual even if everything else passes - they are looking for people that jury-rig their failing vehicles to pass.

Since there is no factory diesel 4runner I hazard a guess one will have a hard time passing a smog test since the test is linked to the vehicle vin and factory profile correlated against state emissions standards.

Or I could be wrong af

Once you have clearance for the conversion, then you are good to go. It's the same thing with this Cummins motor. The motor is completely certified, just like a donor TDI motor. They simply hold the swapped vehicle to the standard of the new fuel type. With my diesel Land Cruiser, it was a simple opacity test.

FYI, I emailed Cummins about transmission adaptors for the 2.8 and this is their response below. Sounds like they're going to stick to the engine side of it (as they should) and let the aftermarket help us put everything together. Good to know that there IS someone working on this.

Hello,

Although Cummins has no immediate plans of offering OEM specific adapters, there are currently adapters in the aftermarket to work with Toyota transmissions. However, it should be noted that consumers must ensure that the transmission they are adapting to is capable of handling the input torque of a diesel engine

Thank you for your interest
