    MAN. You can buy an entire 6.5L turbo drive train for about HALF what they're asking.

    Would be great to see performance/dynamometer testing results.

    Sounds kind of high for the price they are asking. I donít remember the name but there is a company that made them for the military Hummers and you still can get it from them I thought the price was about 3000 for a 6.5 complete set which is a well-known company I just canít think of the name for the life of me right now.

    I can understand wanting to get their R&D money back. But is 50 Horsepower worth $4K? If I lived at higher elevations I could see a need for one. But not at that price. With so many trucks coming out maybe another company will produce one also. Nothing better than competition.

    I would not mind putting a turbo on my 6.2 in the interim but not at that cost.

Maybe after all these years I have gotten my moneys worth from it. Who knows. But I would be afraid I would be in the same boat turboing my 998. I have drove a few Humvees with the 6.5 turbo and 4 speed. Yes they are more powerful but not by much. And not enough to justify that kind of money. The "cool factor" is not high enough to drop 4K.

    To swap in a 6.5 would be 2-3k plus lifting the vehicle and changing the doghouse.

    To swap in a set of 6.5 heads and turbo setup with oil pump and such would cost 1-2K.

    I'm working on something similar to the head swap, but the HUMMV is a PIA to find space for the turbo unit itself.

    Perhaps a group order might bring the price down.

    BTW, it is 4-5K NOT 4K. You need to read the small print.
