Diesel Conversions

Mash Motors has been in business for over four years and is located in the heart of the Midwest, Wichita Kansas. We specialize in Duramax Diesel Conversions for the Hummer H1 and H2 and large SUVs including the Chevy Suburban, Yukon, and Avalanche.

We have now completed over 40 Cummins 4BT conversions to date in 40, 55, 60, and 80 series Land Cruisers. Currently there is a wait for these conversions. However, feel free to give us a ring if you have questions and want to get on the list. Please, serious inquiries only.

We have been reusing the stock A/C systems, retrofitted to the 4BTs, and have retrofitted aftermarket cruise control systems to work with factory systems for 80 series Land Cruisers so there is no loss of functionality.

Here at ECR we've had a love affair with the Tdi (or turbo diesel) Land Rover engines for many years. We've seen these engine perform all around the world for many years, and we've tested them on some of the toughest terrain and conditions that North America can offer, from remote wilderness exploration and temps. well below zero during Maine winters, to the extreme trails of Moab, Utah and 11,000 foot high passes in Colorado! We have found these engines to be robust and fuel efficient.

Forums about Cummins 4BT & Diesel Conversions

Tired, old CJs in failing health are unable to meet the current emissions standards, and are losing their place on California streets, roads, and highways. The only conceivable (affordable) solution available at hand is the conversion to a diesel power-plant, as both sides of the fence meet at the half-way mark. This is just the beginning.
