Not sure about the one on the left. Looks like some sort of stock (factory car) T3 unit. The one on the right looks like a T3/T4 hybrid with a small shaft T4 compressor on it. Can you remove the compressor housing and measure the minor and major of the wheel?
The one on left is my stock turbo i put up for reff i need to remove the bell to get size of intake wheel but i know its the same size opening as exhaust side around 6 mm
