H1C WH1C 62mm Billet Compressor Wheel and Compressor Housing

This kit includes a machined plate to fit an HX35 front collar which allows the Hx40 62.45 x 86 wheel and housing to fit your factory H1C turbo. This kit includes an upgraded rebuild kit which increases the durability and reliability of the H1C turbo.

Specs: 62.45mm by 86mm billet compressor wheel which is rated for 500hp with the stock H1C / HX35 turbine and 600 hp with a 64 or 67mm turbine. This kit is a direct fit on to H1C and WH1C turbochargers. If you have the 3 inch inlet H1C you will have to change your intake to adapt to the 4″ inlet, other wise this kit is also a direct fit for an H1C turbo that normal has a 3″ Inlet on the compressor housing.

This upgrade kit is a great way to upgrade a factory H1C to an HX35 / HX40 hybrid if you don’t want to upgrade the factory turbine wheel (exhaust wheel). Or you can use this kit to convert your factory H1C to and HX40 spec H1C by also upgrading the turbine housing and turbine wheel shown here.

The factory H1C with a 3″ inlet has a 50mm x 78mm compressor wheel and the 4″ inlet WH1C / H1C have a 56mm x 83mm compressor wheel. The H1C turbine wheel is the same as an hx35 turbine wheel which is 60mm x 70mm. The HX40 turbo chargers have a 64mm x 76mm turbine from factory which can also be upgraded to a 67mm x 76mm turbine wheel if the factory H1C turbine housing is machined or if matching housing is used.

HX40 Compressor Wheel and Housing

We are proud to provide new HX40 compressor wheel and housings for easy HX35/HX40 hybrid upgrades!

Here are the details:

  • Brand new 62.45 mm x 86mm compressor housing for 7 blade HX40
  • Brand New 62.45 mm x 86mm x 90mm Extended Tip billet compressor wheel

Compressor Wheel Details:

  • Slimnose hub
  • ~145 grams (larger but weigh about the same as stock)
  • Thin blades
  • Machined from solid aluminum
  • Extended blades
  • 60 x 86 x 89.5mm
  • Balanced and ready to install

What else do you need To know to install this on your HX35 or HX40:

  • Your bearing housing must be machined to 87.5mm to accept the HX40 compressor Wheel
  • HX35 7 blade compressor wheels are 54mm x 78mm, so the bearing housing will need to be machined from 79.2 to 87.2mm for the compressor wheel to fit
  • HX35 8 blade compressor wheels are 56mm x 83mm, so the bearing housing will need to be machined from 84.2 to 87.2mm for the compressor wheel to fit
  • Take note that the HX40 8 blade is 57mm x 82mm, so the bearing housing for that will have to be machined also
  • We do machine bearing housings for $20, but most people take their bearing housing to a local machine shop, so they don’t have to wait on shipping down time

HX35 64mm x 76mm turbine Wheel and exhaust housing upgrade.
Please Read Carefully: This Housing is made to directly fit 1989 1997 24v turbochargers as a upgrade.  To work on other models modification is need as listed below:

1989-1997, have some variations of the factory turbo charger, this turbine housing and wheel work as an upgrade to the H1C and HX35, even though there are different version, in which some did not include wastegate actuators, this housing is still a direct fit on the factory turbo chargers in combination of using the turbine wheel included. This kit is intended to be used with a compressor upgrade 60mm, 62.45mm, or 67mm.

The turbine housing in this listing has 4 drilled through holes at the t3 flange, because the 12v engines use 4 studs threaded into the manifold. The 24v cummins (98- 02) has 2 threaded holes on the turbine housing and 2 threaded holes on the manifold to use studs. If this housing is used on a 24v cummins, 2 bolts and nuts will need to be used to bolt on the turbine housing because the exhaust manifold and turbine housing is not threaded for studs and the manifold is only threaded for 2 studs. If you are using this kit on a 24v you will not need to use the factory 24v wastegate actuator and mount on the compressor housing.

–If you are using this turbine housing on a 12v turbo with a horizontal mounting wastegate actuator, no actuator, or vertical wastegate actuator, this is a direct fit.

Modifications Required to fit 12v model turbos: (there are 2 versions of 12v Engines)

-To fit 12v turbos normally using horizontally mounted actuators, the threaded holes must be drill on the t3 flange for the manifold studs to go through the turbine housing. (thats it!)

–Some 12v models cannot use the horizontal actuators because they interfere with the oil drain which won’t allow the turbo to bolt on. However, the vertical mounting wastegate actuator is universal, there for this turbine housing upgrade is a universal fit for both model 12v engines.

Details of the listed items:

Upgrade for the 12v & 24v 5.9 cummins

Includes:

  • Fits 1989 – 2002 12v & 24v cummins factory HX35 turbo as upgrade
  • Direct fit for 1989 – 1997 12 valve turbo chargers / engines
  • 2 bolt and nuts are needed to fit 1998 – 2002 24v because no threaded holes on t3 flange (no threads for studs)
  • HX40 67mm x 76mm turbine shaft
  • HX35 turbine housing machined to HX40 67mm x 76mm turbine
  • 5 bolts
  • 5 bolt flanged machined to the 67mm x 76mm turbine
  • 5 bolt downpipe gasket
  • The Wastegate orientation is mounted on the compressor housing.
  • Wastegate not included.
  • Recommended to use this turbine housing with HX40 60 x 86 or 62.45 x 86 billet compressor wheel
  • Condition is New

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

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!
