Thread: Conversion Cummins ISF 3.8 (or 2.8)

The other thing is the comparatively low governed speed I suppose. Doing some reading the SCR is an AdBlue system - so there's that to take into account, too.

Definitely food for thought

Cammo, where are you getting the SCR/adblue info from? I didn't come across that in the Cummins literature. I read the ISF3.8 is Euro IV emissions compliant, the ISF2.8 in the Foton is Euro V emissions compliant. I may be very wrong but i understood Adblue was (generally) introduced to meet Euro VI emissions. I'd want less invasive systems not more which is why the Cummins is attractive.

in answer to your earlier Q about a cooled EGR, a quick search on Alibaba has for sale an EGR cooler that looks to be water cooled. Maybe a Sat arvo in the shed to fit an EGR blanking kit and terminate the cooling hoses or redirect those hoses to a hot water shower for the loving wife.

Mark,

Info from Cummins Australia ISF brochure (.pdf)

Lists SCR as a means of emission control and goes on to explain SCR in all its AdBlue glory on page 2.

Not sure if its on all of them or for what application or anything - might be panicking about nothing - but AdBlue would kill the option off for me I reckon.

That is, of course, if it cannot be easily omitted from the install.

I did go through a small stage of weakness where I thought I might've fancied an LS3 swap. Or one of the smaller capacity LS derivatives they use in any number of "pick-ups" over there in 'merica. I still think I fancy an LS'd Rover - just not for touring duty.

I told you that story as a long winded way of introducing you to another Cummins alternative - the ISV. I know less than nothing about it except that it is allegedly USA built, and is a 5.0L V8 turbo diesel found under the hood of a Nissan Titan.

I need to win lotto...

PS: sorry for thread highjack ref ISV.

Hi Cammo - I hadn't come across the AU Cummins info which differs to the USA material by referencing SCR (omitted in the USA material). That info changes my earlier info on emissions as the Adblue (SCR) on the AU delivery engines brings emissions in line with the current AU emissions standards. Good news for those with younger than 2013 vehicles, for older than 2013 vehicles I think you would get away with the crate engine out of China that is Euro IV compliant (no SCR) (noting that ADR79-02 applied up to 1 Nov 2013 which is a hybrid of Euro IV in its transition to Euro V).

If you jump on Cummins USA website they are taking a poll on what engine to next release as a crate engine. The ISV 5.0 V8 diesel would be a treat but $$$$. At 800nm in standard tune you are rebuilding everything in the drive line to handle the extra torque. Makes it an expensive exercise.

Maybe some fire chat for LR expo next month.

Hey Mark,
As stated, as long as there's no SCR, I'd still be interested in the ISF from a practical, sensible point of view. The ISV WOULD be a treat but agree with rebuilding the driveline to handle the torque. Hence my comment regarding the lotto win..
I wonder if it can be "detuned"? The thought of cubes distributed evenly between 8 cylinders makes my inner, highly suppressed revhead tingle at the mere imagination of the symphony..

Cummins Now Taking Orders for their R2.8 Turbo Diesel Crate Motor

I saw this yesterday

Don.

Some how i made it onto Cummins email list. Some info they sent by email. Now we just need them to release the 3.8 as a crate package.

Season's Greetings, The all-new R2.8 Turbo Diesel crate engine package has been on sale for just over two months now and Cummins Repower has been shipping engines all over the U.S. and Canada for projects ranging from simple repowers for daily drivers and iconic 4x4s to custom installations into wild, retro RVs. We’ve done our best to take the guess work out of an engine swap. No other new production crate engine comes as complete and ready to run as the R2.8 Turbo Diesel. Cummins Repower provides everything from the front-end accessory drive to the digital dash display and the throttle pedal. Each crate engine we deliver matches the exacting specifications developed by Cummins and our BETA test customers, who punished the R2.8 Turbo Diesel in testing across multiple vehicle platforms. Not all engines are crated equally. When critical components such as fuel pumps, filters, accessories, starters, and flywheels aren’t included in an engine package, you have to piece together these components from various manufacturers, hoping for the best. For the vehicle specific components not included with our R2.8 Turbo Diesel, such as motor mounts and cooling packages, we help you by including the most thorough installation guide and owner’s toolkit available in the crate market, as well as on-call support from 1-800-CUMMINS. A team of dedicated enthusiasts is standing by to help. We hope you choose the reliability of a complete Cummins Repower crate engine package for whatever your project might be. To show our appreciation for your interest, we are excited to offer free shipping on all crate engines through the end of the year.
Each R2.8 Turbo Diesel includes:
R2.8 Turbo Diesel engine assembly Complete front-end accessory drive (Alternator, Power Steering Pump, Fan Hub, Serpentine Belt) Cam-Driven Vacuum Pump Remote Fuel Filter/Water Separator Remote Oil Filter		Mass Airflow Sensor and Housing Engine Wiring Harness and Engine Control Module Starter Flywheel Universal Vehicle Wiring Harness				Throttle Pedal J1939 CAN Dash Display Owner’s Manual** Installation Guide** Cummins Quick Serve Online Access**
**In some cases, printed materials may be shipped separately at a different date than the crate engine shipment. Happy holidays and safe travels
