H1C and WH1C are only interchangeable on the turbine side. The superback on the compressor side is different. Most of the turbine upgrades come from the H1E turbocharger.

The HX35 and h1C turbochargers have a 70x60 turbine.

The 351cw has a 65.5x58 turbine.

The HT3B is a holset reverse rotation turbocharger that Schwitzer made replacements for as well.

The HT2B is not predecessor to the S300.
