6.6L Duramax-Powered Chevrolet Colorado Is Too Interesting For Us To Ignore - GM Authority (blog)
Before we jump in to this street-racing video we have to say the following: we don’t promote street racing. First up, we have a Nissan GT-R running E-85 with full bolt-ons. While the specifics of the bolt-ons aren’t identified we shall rest assured knowing that they are, at the very least, “full”. In stock form the GT-R could run anywhere from 485hp t0 542hp, depending on model year, so its fair to say this car is producing 500hp at the bare minimum. In the other lane we have a highly–HIGHLY–modified first-generation Chevy Colorado. Under the hood sits a long-block 6. 6L Duramax hooked up to a stock Allison six-speed automatic.
