The GTX2971R is a combination of a medium trim GT30R turbine wheel, and a GTX30R series compressor wheel. In this case, the GTX2976R uses a GTX3076R Compressor Wheel.
The GTX2976R Supercore fits directly into any existing GT3071R Medium Trim exhaust housings. These can be found on the following:
GT3071R – P/N: 836027-5002S AKA 700382-5020S
Turbochargers using the CHRA P/N: 835999-5002S AKA 700177-5004S.
Product Notes:

This GTX2976R will bolt directly onto CA18DET/SR20DET factory exhaust manifold and dump pipe, however, due to the different style of compressor cover used, some intake and intercooler pipe modifications are required.
The Turbine Wheel is cast from Inconnel material for extreme applications.
This turbocharger has a ported shroud/surge slotted compressor housing to increase surge resistance.
