    Number 1, because this conversion package requires the transmission to be moved forward, the floor pan and potentially the lower portion of the dash will need to be altered to clear the shifter.

    6.0L AUTOMATICS

    5R110-  These transmissions work very well in the conversion.  The advantages of using the Ford factory TCM is that you keep the tow/haul functions, retain your factory diagnostics with regard to the transmission, and the stock shift quality adaptive function is retained, and no additional wiring.

  5. Chevy 1988-1999 4x4 with IFS

    Fitment of the Cummins engine is tight but results in a great conversion because you get to keep your IFS. 

    • Keep IFS ride quality
    • No Body Lift Required
    • Electric Cooling Fans
    • Water-to-Air Intercooler
    • Keep cruise control
    • Factory instrument cluster works- Gas and Diesel

     

    The space from the firewall to core support is limited.  You may be able to run the mechanical cooling fan but it will require a body or suspension lift and additional fabrication work.

    AUTOMATIC TRANSMISSIONS

    Modern, electronically controlled transmissions are better suited for conversions than the automatics transmissions of yesteryear due to shift control, overdrive, and torque converter lookup.  The electronic controlled transmissions (4L60 & 4L80) do not require replacement valve-body, kick-down linkages, etc. it simply plug & play.  A throttle position sensor is required when using

  6. Ford F-450 & F-550 Conversions

     F450

    The Super Duty F-450 & F-550 trucks are a popular choice for conversion projects.   These vehicles combine the amenities of a modern pickup truck with very impressive towing and hauling capabilities.  The following information highlights some of the pertinent differences in the F-450/550 trucks as compared to Ford’s standard F-250/350 models.

     

    Gear Ratios and Tire size:   The larger Super Duty trucks offered axle ratios of 4.30:1, 4.88:1, and even 5.38:1.   Because a higher ratio number also means higher engine RPM, these ratios are considered deep as compared to an F-250’s 3.55:1

  7. 2008-2010 Ford 5.4L or 6.8L

    Many times customers ask about converting 2008-2010 Ford ® 5.4 and 6.8 trucks to a diesel due to the fact that they can be purchased reasonably, or they already own the truck and would like diesel power. There is not too much difficulty with this conversion, as these trucks have the same frame and transmission mounting as the diesel versions. You should plan to drop the fuel tank and remove the electric fuel pump. This is explained further in the installation manual. Keep in mind that a new diesel exhaust system will also be required and a diesel radiator is also a good idea if you plan to do some considerable hauling. The 2008-2010 Ford radiator and intercooler swap requires more parts than the earlier 2003-2007 models- and if the parts are bought brand new they are fairly expensive.

    It is recommended that a F-250 or heavier duty chassis be selected for 6-cylinder conversions, as the F-150 chassis is really too light duty to handle the power and weight of

  8. 1999-2007 Ford 5.4L or 6.8L

    Many times customers ask about converting 1999 - 2007 Ford ® 5.4 and 6.8 trucks to a diesel due to the fact that they can be purchased reasonably, or they already have one and would like diesel power. There is not too much difficulty with this conversion, as these trucks will accept a diesel Super Duty intercooler without modification and the frame and transmission mounting is the same as the diesel versions. You should plan to drop the fuel tank and remove the electric fuel pump. This is explained further in the installation manual. Keep in mind that a new diesel exhaust system is recommended and a diesel radiator is also a good idea if you plan to do some considerable hauling.

    It is recommended that a F-250 or heavier duty chassis be selected for 6-cylinder conversions, as the F-150 chassis is really too light duty to handle the power and weight of the 6-cylinder Cummins ®.

  9. 1999-2003 Ford 7.3L Diesel

    INFORMATION FOR ALL 7.3L MODELS

    The Super Duty ® 7.3L trucks are one of the easiest trucks to convert to Cummins ® power. No modifications to the firewall, core support, or floor pan are necessary. The stock radiator and intercooler can all be used as is with the Cummins engine, and the fan shroud works with minimal modifications.

    When you buy Diesel Conversions ® parts we include year specific installation instructions. This includes wiring instructions for customers using the 12-Valve 6BT or the 1998½ - 2002 24-Valve Cummins engines, or if you would prefer, you can opt to have us do the bulk of the wiring work for you by sending in your 7.3L engine harness to be modified, as we do with the 2003 and newer Cummins engines.

  10. 1980-1997 Ford F-250+

    General information for all F-250, F-350, and F-Super Duty:

    You will need to cut holes on your radiator support and also trim the back of your 80-91 grille to allow the intercooler to be installed. Some adjustment on your firewall and passenger side toe board with a large hammer to make some more room for the valve covers and exhaust is also necessary. This is explained in greater detail in our installation manual.

    Diesel radiators are recommended for extra cooling capacity if your truck currently has a gas engine. Radiators that have X braces in between the radiator and the engine or any that are wider than 31” don’t work well in the conversion. You may consider swapping in a 96-97 Power Stroke ® radiator with the remote fill tank. These radiators have the hose connections on the same side as the Dodge ® radiators making them easier to connect to the Cummins ® engine. Diesel and Gas truck radiator suppor
