Holset H1C H1E Turbo Compressor Upgrade

For The Holset H1E and H1C, There are a Lot of Upgrades, But It is Important To Understand That The Most Important Upgrade is Our Rebuild Kit Which Prevents Common Thrust Bearing Issues. You Can Find More Information About Our Rebuild Kits Here.


Next You Must Understand That The Compressor Plate for the H1C H1E Turbos Can Be Machined to Use the HX35 HX40 Thrust Collar, Which Allows You to Run the HX35 HX40 Compressor Wheel Upgrades Below:

Here are a List of the Compressor and Turbine Upgrades:

Billet Compressor Wheels

Turbine Shaft Upgrades

  • 60 x 70 (Factory H1C HX35 Turbine)
  • 64 x 76 (12 Blade and 10 Blade Turbine) (Most Common H1E Turbine)
  • 67 x 76 (12 Blade and 10 Blade Turbine) (Some Were from H1E’s from Factory)

NOTE: Machining Is Required for all of the Compressor Wheel Upgrades for the H1C, but for the H1E 60 x 83 Compressor Housing, The 60 x 86 4015c Billet Wheel Is a Direct Drop In After the Compressor Plate is Machined for the HX35 HX40 Thrust Collar, and the Collar Must Be Use in the Build. This Makes for a Super Easy and Cost Effective Upgrade!

These Upgrade Also Work for the HX35 HX40 HE341and HE351!

HX40 10 Blade Turbine Wheel

HX40 10 blade turbine WheelThe Holset HX40 10 Blade Turbine Wheel is From the HX40 Super Turbo. The HX40 Super Turbo is a Very Popular Turbo Because it is More Powerful than the Regular HX40, Despite the Only Difference, is the Turbine Shaft Having 2 less Blades and Less Weight!




This is One of the Turbines that I just Had to Get My Hands on For Upgrades! However this Isn’t the Largest Turbine Upgrade for the HX40 (We offer 67 x 76mm 10 and 12 blades Turbine), This is a Perfect “Direct Drop in” for the HX40 turbos!

This Turbine is 64mm x 76mm and Has 2 Less Blades so It helps with Spool Up and Peak Power!

We Offer the Sell This Shaft, as well as providing it with a Service. If You are interested in Buying This Shaft You can Buy it Here:

HX40 10 blade Turbine



HX40 10 Blade vs 12 Blade Turbine Wheel

Generally when a Turbine Shaft Has Less Blades, it relieves more Back Pressure from the Turbine Housing Which will Keep Your EGT Temperatures Lower.  Having Less Blades Can Cause Later Spool Up Because It Requires Higher Pressure to turn the Shaft since More Back Pressure is being Released.

However, With the Turbine Having Less Blades it Weighs Significantly Less than the 12 Blade Turbine, Which Helps Reduce Turbo Lag. Having Less Blades Also Helps increase Top End Power and Prevent the Engine From Outflowing the Turbocharger at High RPM, Which Causes High EGTs!
