How to pick the right diesel engine for my vehicle?

Considering a Custom Diesel Conversion? There are a few things to keep in mind….

  • Weight of Vehicle: How heavy is the vehicle? Are you selecting an engine that is appropriate for the weight? Is the vehicle’s current engine similar in weight to what your selecting for conversion engine?
  • Rear Gear Ratio: Depending on conversion engine, you must consider how high you are going to be revving the engine, and how low your vehicle is geared.
  • Performance / Drive-ability goals: Are you wanting a powerhouse, or fuel economy? Will there be enough power to tow, or just enough to commute? Consider Horsepower and/or torque per pound compared to original engine.
