PICKING THE CORRECT CUMMINS

PICKING A CUMMINS ENGINE There are three types of fuel systems used on the 5.9 Cummins engines, and these differences are the only major aspects that set them apart from each other. The engines are universal as far as transmission mounting, if a tranny fits one engine, it will fit another (providing the proper adapter plate is used). For states with emissions inspections, the general rule is to go with an engine of the same year as, or newer than the implant truck. Check with your local emissions inspector for specific laws that apply to your project. Some preferences to consider are fuel economy, horse power and torque, mechanical or electronically controlled fuel system, noise level, ease of installation, governed RPM limit, and purchase price. Industrial/Commercial engines are not as conversion friendly as the Dodge versions. Click here to read more.

The simplicity of the 12-Valve engine makes it the easiest to install, maintain, and most dependable. RPM RANGE 0-2500 Bosch VE Rotary Pump 1989-1993 Stock Equipment (most automotive applications) Max Stock Torque - 400 ft./lbs. @1600 RPM 0-2700 Non-Modified P-7100 Pump 1994-1998 Stock Equipment Max Stock Torque- 440 ft. /lbs.@1600 RPM 0-4000 Modified Inline Pump (we make available) Industrial Cummins Engines We offer this information to make you aware there can be many differences between an Industrial Cummins engine vs. a Dodge Cummins engine. The cost and time switching these engines over can be substantial. 89-93 Engines: These sometimes have a different injector pump (LUCAS) that does not work well in auto applications- if the pump is not a Bosch VE (Rotary) it will have a different front ‘timing’ cover and most likely a different pump gear as well. 1989-1990 engines were not intercooled. Even if your engine was intercooled the turbo outlet and inlet can be different. Other parts that differ on industrial/commercial Cummins engines are: - Throttle linkage and cable - Lower rad hose connection, a/c pump bracket - Fan support/pulley - Thermostat housing/alternator mount - Belt tension bracket - Oil pan and pickup tube (too long of a sump) - Exhaust manifold - Air horn - Sometimes these even have lower compression pistons than the automotive versions 94-98 Engines: These engines may have different fuel and governor calibrations, and also have different parts such as the following: - Injector pump with no tapped holes for Dodge style throttle linkage - Throttle linkage - Lower rad hose connection, a/c pump bracket - Fan support/pulley - Thermostat housing/alternator mount - Belt tension bracket - Oil pan and pickup tube (too long of a sump) - Exhaust manifold - Air horn (Intake) - Sometimes these even have lower compression pistons than the automotive versions 99-02 Engines: -- Injection pumps don't work with Dodge electronics! - No engine performance or "tuning" capabilities - Much lower governed RPM is common (as low as 1,900 RPM!) - fly-by-wire TPS (throttle position sensor incorporated in the accelerator pedal) - Lower rad hose connection, a/c pump bracket - Fan support/pulley - Thermostat housing/alternator mount - Belt tension bracket - Oil pan and pickup tube (too long of a sump) - Exhaust manifold - Air horn (Intake) - No factory engine diagnostics unless you have Cummins Insight® Options: 1.) Use a mechanical injection pump from a 1994 -98 Dodge 12 Valve engine known as “P-pumping” the 24 Valve engine 2.) Get ALL of the DODGE electronic engine components (VP44, ECM, PCM, TPS & throttle cable) 3.) Keep the existing engine components and sacrifice functionality of the converted vehicle 03 and newer Don’t get one of these industrial version engines, our adapter plates will not work with them. These engines use a rear gear drive system and the adapter connection is totally different!
