N1 oil pump question

[Driver]

Hey all

Ive heard that on the r32 gtr n1 oil pumps they have an extra screw on the back compared to a standard gtr oil pump.

Is this correct?

Any info appreciated

thanks

The only difference externally with mine is where the oil pressure relief spring cap screws in , I think the std one is flush with the lower rail of the pump and the N1 version projects below the rail on the crank case side . I guess the N1 spring/s must be longer and slightly higher rate , SK tells me the the mechanical part of the two R32 pumps is identical .

Cheers A .
