hybridz and dsmtuners both use holset hx35, hx40 and hx52 found on cummins motors, mostly the smaller stuff.
Bullseye power make a bolt on turbine housings to make the turbo suit petrol application, although they can be used with standard turbine housings.
Depends on what engine it's going on and how big the turbo is. The holset I have is off a 6.7 but it's only ~gt35 size, a tiny bit bigger.
