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!

NOTES:   This Upgrade Also works for H1E H1C, But the Compressor Plate must be Machined for the HX40 Thrust Collar (easy job). For the Holset HE351VE VGT Turbo, This Upgrade is Possible, But The Turbine Upgrade is limited to a 64 x 70mm Turbine. The Exducer of the VGT Shaft Upgrade is Limited to 70mm Because the VGT Arms Hit the Turbine Shaft of the 76mm exducer.
