H1C Turbo Upgrade Kit

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 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.

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.
