Holset HX35 Turbine Housing Machining

Holset HX35 Turbine Housing Machining

At Turbo Lab we can Machine your HX35, H1C, or HX40 Turbine Housing to a larger Turbine Wheel. The Factory HX35 Turbine Wheel is 60mm x 70mm, and the Turbine Housing can be Machined to the HX40 64mm x 76mm and the HX40 67 mm x 76mm Turbine Wheel. Machining Your Turbine Housing for the Larger Turbine Wheel, will Help Lower EGTs, and Drive Pressure Significantly.

You Should Upgrade Your Turbine Wheel or Turbine Housing Size If you have Already Machined Your compressor Housing for an Hx40 60 x 86 Compressor Wheel or Larger. You need to use a Turbine Wheel in Sink with the Compressor Wheels Flow or close. The closer and Flow Rates the Compressor and Turbine Wheel are to each other the more Efficient your Turbo will be and the Faster It will Spool. If you use a 67 x 89 x 95 Billet Compressor Wheel then you Should use a 67mm x 76mm Turbine Wheel. If You use a 64mm x 76mm Turbine, You can Compensate by using a Larger Turbine Housing.

If You need us to Machine your HX35, H1C, or HX40 Turbine Housings, We can do that for You and we have all of our Programs on CNC.  You can Contact Us Here.
