Duramax Diesel Engine Conversions for the Hummer H1, H2 and Large SUVs
Mash Motors Inc. is world-renowned for our Duramax Diesel conversions for the Hummer H1, H2 and large SUVs including the Chevy Suburban, Yukon and Avalanche. We are also the first company to successfully convert the Hummer H3 with the Vortec 6.0 liter engine and 4L60HD transmission by GM.
With a conversion from Mash Motors Inc., you won’t lose any of your factory accessories and all wiring is completed in a manner that allows your factory settings to be maintained.
Horsepower and MPG Expectations
The base conversion package starts out with 400 horsepower. Performance upgrades and modifications can increase the horsepower to 750. The biggest gain from the conversion is the outstanding fuel mileage from 9 to 12 MPG in a stock Hummer to 18 to 26 MPG and is capable of running on biodiesel.
Each conversion is completed to the customer’s specific requests and therefore, build time is approximately 45 days for the H1, 25 days for the H2 and SUVs. This ensures that each conversion is completed properly and the vehicle has been thoroughly inspected and road tested prior to delivery.
Diesel Drive Train Core Charge
Mash Motors Inc will retain the old drive train and components that are removed from your vehicle during the conversion process. The stock motor and transmission will be used as a core charge for the diesel engine and Allison transmission. If you want to retain the stock motor and transmission there will be a core charge of $2,500.00 added to the conversion cost.
