om606 HE221 (T25) Installation Kit for Holset Turbos - 12AN

Mounting a Holset HE221 or other T25 frame turbo to your om606 can be a difficult task.  Well no more!  The BenzForce HE221 for om606 Kit takes the headache out of the physical connections.  All that is needed is a 4AN feed line and a 12AN drain hose.  

** Turbo not included

Here is what is included: 

 

Wastegate Installation Instructions:

  • Remove the wastegate hose
  • Remove the wastegate actuator. After pulling the internal pin allowing the compressor housing to rotate independently, just remove to cotter pin on the wastegate (or a C-clip on the 5.5 cm2 models) and the two bolts holding the wastegate on the turbo.  This will allow you to completely remove the wastegate.
  • Mount the bracket.  Remove the turbo from the T25 flange.  Place, or replace, a new T25 gasket on the flange.  Then install the wastegate bracket, followed by another T25 gasket.
  • Install the turbo
  • Reinstall the actuator.  Rotate the actuator 180 degrees from its original position.   Put the end over the pin on the turbine housing and install the original cotter pin or c-clip.  Then pull the actuator and insert the original two bolts through the bracket and through the stock actuator bracket.  The actuator comes pre-loaded from the factory so pulling the actuator should put the same amount of tension on the actuator as the original configuration.  Use the included copper exhaust nuts to secure the actuator to the BenzForce bracket.
  • Install boost hose.  Depending on how the turbo is clocked, you can either reuse the existing boost hose or you may require a new one.  Regardless, reinstall the hose so the actuator will see boost from the compressor housing.

 

Note that the HE221 has clocking pins inside the turbo.  Both the compressor and turbine housings pins will need to be removed in order to rotate the core
