Cummins Repower ISF 2.8 for Defenders

I drove one in a 110 before I bought my 300Tdi. I just wanted to see if it would tell me what it might be like. The Cummings should be a bit more powerful than the 300Tdi.

It felt pretty good. It took hills well, and although it was not quick, it was quick enough. Certainly was drivable on modern streets, etc...

Still rather run a Td5 myself if I needed more freeway manners than the 300tdi.

We've got a crate repower project in the works with a NV3550 planned...

That's an established route to go, which is always good. I do worry about the overall length of the drivetrain on 90's.

Do you have a willing victim, I mean volunteer or paying customer in mind? Is it a 90 or 110?

Why is this thread in the "LS Engine Conversion" section? How about a new section for diesel conversions. Cummins, Duramax... Kind of like a smoking and non-smoking section!

How about just a non-rover engine section - diesel, gas, LPG, chevy, LS, Isuzu, and all the other hand crafted bastardized Defender iterations...

Not a bad idea. Hope your customer allows you to post your work on his 110.

Rumor has it the kit along with the wiring harness,ecu, and accel pedal, is going to come with one of these so you can run query the ecu via canbus functions in your ancient analog defender.

That would be cool.

Anybody watching the Rover build featured in the Cummins update? Xtreme Off-Road on Power Nation TV
I'm not normally a fan of those shows but I am interested in the engine install. I hope they don't skip over the details.

First, just for clarity, it the R2.8, not the ISF 2.8. Two different engines.

The specs/pricing will be released in May. They are indeed working on the final EPA stuff. There are two Land Rover places that have beta engines but I am not sure who they are--the folks at Cummins are checking with them to see if they are cool with them releasing that info. I am planning on the swap with the LS as my back up in case things either get ridiculously delayed or too darn expensive. I know folks at Cummins Rocky Mountain and it isn't released to even them yet. But I am excited.

RE: Colorado and the 300/TD5. I can't do either. The State now truly inspects the engine swaps, particularly like me going from petrol to diesel. I have to tell them which US sold truck the engine came out of or provide them with the EPA documentation showing certification in the US. (the other requirements are the engine has to be newer than the truck, it has to be the same weight class (ie no 6BT swaps which is a "heavy weight" class, and all emissions equipment from donor vehicle and all applicable sensors must also be used.

I plan to do a full write up of my swap including making engine mounts and everything to help other enthusiasts. If you are one of the shops already doing this, please share! I am working on getting the requirements of the intercooler (charged air they call it) as well as the hose dimensions so we can be prepared for that.

The LS is an awesome engine. It is on the table still for me, but I frankly would prefer the diesel. Sure, I could quote data points like mileage, but they are rather irrelevant--it is a decision made more by want than by logic.

The engine swap will be 50 state legal for vehicles 1999 and older.

There was a torque/horsepower graph of the R2.8 at one time and it was taken down. Does anyone still have that?

That's the first I've heard of CO having Cali style emissions laws. That sucks. Does that only apply to CO titled vehicles that are undergoing a swap or would I have trouble with the 200tdi in my 110? Only asking because CO is on the list of potential places to move if jobs work out.

That info is for swapping from petrol to diesel in particular. Raymond, who is head of the diesel division for Colorado Dept of Environ is the gate keeper. Super nice guy, really straight forward and upfront. It has nothing to do with emissions--it has to do with re-titling the truck from petrol to diesel which you need to do in order to then get emissions.

Again, nothing to do with emissions--just re-title of the truck to diesel. I can get you his number and contact info--he has been the nicest govt employee I have ever dealt with.

A factory 200Tdi is no problem in Colorado as my 1991 was inspected and I was able to get my required documents for title and plates.
Now Denver proper is a lot different that other counties including Boulder (more strict than Denver). I can put you in contact with the person responsible for Colorado Springs as I have worked with him several times.

In Colorado ALL diesels require inspection and testing. A manual test can be performed if a 4 wheel testing unit is not available in county/city.

Colorado shouldn't pose any problems as long as the vehicle is diesel per the title and registration.

The front range counties require annual emissions tests for all diesels but they are easy to pass. My 2.5na passed with no issues as did my 200tdi every year after I swapped that in.

It's not a factory 200Tdi though why is what concerns me with some of the emissions talk going on in various states. At least NJ recognized the benefit is far outweighed by the cost to check old vehicles. I also have a straight 2.5 in exhaust with a small muffler so I doubt I'd pass any emissions test.

But it looks like the job in CO is not going to work out. Thanks for the offer though, I'll keep it in mind should plans change.

I have a straight 2.5 inch exhaust. With no muffler. They don't care. There is no visual inspection, it's just an opacity test on what comes out your pipe while it's on the dyno.

That said, CO (front range anyway) is an overcrowded mess anyway.:(

Its all seems quite close now.....
Costwise I suspect that this is going to cost as much as say a Chevy crate engine and box conversion.

Strangely, I'm really excited about this. I really prefer to run a stock Land Rover motor in my Defender but I just love the Cummins 6.7L in my Ram 2500 so much. It's a fantastic product and I'm sure this one will be, too. Very much looking forward to making NAS-ROW the #1 place for Cummins-powered Land Rovers.
