Under the hood is the Toyota 2H, 12-valve, 4.0L I-6 diesel engine. Stock, this engine has a compression ratio of 20.7:1 and it produces 107hp and 177 lb-ft of torque at a lowly 2,000 rpm. Floyd had a custom 3-inch-diameter exhaust installed as well as a Denco turbocharger to “provide a bit more boost in the mountains.” We’re guessing Floyd saw a significant increase in horsepower and torque with the addition of the turbo. Power is routed through a Toyota H41 four-speed manual transmission and its split to the axles via a Toyota two-speed transfer case with 1.96:1 low range ratio. Combined with the axle ratio of 4.11:1 and the 4.84:1 First gear ratio of the transmission, the rig has a crawl ratio of 38.9:1.
