I think you've got that wrong. I should've searched with the part number stamped on mine. N3A1 are the US twins, N3CI are the '99 twins, and N3G1 are the RZ twins.

N3A1 should be for 93 and N3C1 is for later model. The 99 Spec is N3G1.
The P/N were pulled off from Mazdamotorsport webpage.

The easiest way to check is to look inside the compressor housing, there should be a black plastic liner inside the housing. Thats how the 99 turbos have a tighter tolerance between the compressor blades and the housing. Its called an abradable seal.
