Johnathan Goodwin and his company H-Line Conversions, Inc. pioneered "The Conversion" of the H1 and H2 Hummers from gasoline, 325 hp, and 8-12 mpg to eco-friendly biodiesel 650+ horsepower and around 25 miles per gallon.
With over 100 H1 conversions and 60 H2 conversions, nobody, and we mean nobody has the results that H-Line Conversions, Inc. does. Until Johnathan converted his first Hummer into a biodiesel consuming behemeth, it was believed that it "couldn't be done". Once Johnathan had done the impossible, others followed suit, many if not all having been trained by the master himself.
We've become known for our "can do" attitude where we believe that almost nothing is impossible. Including taking a 1965 Impala, craming a 6.6L DuraMax diesel, turbo charging, and some fancy ECU tuning that puts him in a league of his own producing a whopping 850 horses, then racing a Lamborgini in a Quarter Mile race. Click on the Video above to see the race. Or if power is what you want, the ability to take this 2008 Cadillac Escalade and crank out a tire smoking 1000 horses with diesel/biodiesel or 800 horses with B100. CNN Video
With a proven track record, we've gained the confidence of politicians and celebrities such as Gov. Arnold Schwarzenegger (we converted his 1989 Jeep Wagoneer to BioDiesel), Neil Young (special project to convert his 1959 Continental to a Series Hybrid Electric Plugin) LincVolt, and Tim (Tool Time) Allen modifying an H3 Hummer with a turbo V8 that breaks all 4 tires loose in All Wheel Drive for him as well.
We are mostly converting H1 and H2 Hummers (all years) but will entertain custom orders for other vehicles. Check out our conversion packages at Conversion Packages.
