The Cummins 4BTA four-cylinder turbodiesel engine rests on custom motor mounts. This intercooled engine has been treated to a number of mods by Toxic Diesel in St. George, Utah, including pump tuning and fuel pin. Hummel says these mods increased the engines output by approximately 60hp and 100 lb-ft of torque, which helps the 4BTA generate approximately 180hp at 2,400 rpm and 400 lb-ft of torque at 1,800 rpm. The exhaust system includes a 3-inch “almost straight” pipe and the header and downpipe are heat tape-wrapped to help control underhood temperatures. And speaking of temperatures, the engine is cooled by the stock S-10 radiator with some “creative hose adapting.” Other underhood mods include a GM one-wire alternator, Optima YellowTop battery, and a stock oil pan with “smashed areas for clearance.”
