1st tow with Peninsular 6.5 turbo diesel.

All I can say is very impressed. When we first dropped the engine in I was disappointed but after replacing the exhaust and fixing the leaky crossover pipe the truck has been performing amazingly well. It averaged 13 mpg while pulling an 11000 lb trailer through the mountains this past weekend and has very good power as well.

    I've never owned one but my 79 5.7 LF9 Diesel V8 was enough to say " never again GM".


    Hater!!! LOL

    4X4, is your fuel system stock or is the pump turned up?

    I love my 6.5 but antifreeze is disappearing! :E


    The pump is turned up. The compression ratio is lowered to 16:1, a larger turbo is installed with no wastegate. The new 6.5 blocks have webbing around the main bearings for added strength, the crank is steel, the new heads provide better cooling, we installed a high output water pump along with a Duramax cooling fan and new radiator. We also installed a new 4" exhaust. All the rubber hoses were replaced as well as shocks, brakes, ball joints and tires.
