It's a backwards step from the stock beams sump. The 2s baffling is shite and the pump setup is different. The gen3 and beams 3s motors run the pump pressure relief in the alloy section of the sump. The filter is also mounted on the side of this alloy section.
Putting a 2s sump on this type of pump will mean that no oil reaches the motor, it just gets dumped back into the sump.

To use a 2s sump you'd need to change the pump to a gen 2 style pump, but it needs to have the crank angle sensor provision. Then you'd have a setup that cost money and is rubbish compared to a standard beams setup.

The 2s change is of more use for converting fwd style 3s motors to rwd.
