Would a turbo OMP benefit an N/A?
I own a '91 Vert and I'm curious if replacing the stock OMP with one from a 13-RE will benefit the engine or just be unnecessary. If that wouldn't help engine performance, are there any performance OMP's for the N/A?

It's not necessary.
Remember you need the OMP if you got an S5 and If you decide to change anything to do with the OMP then you need to make sure it is Compatable with what the ECU is going to see..or the engine goes into LIMP MODE.
Only other way is to Premix and Place the OMP aside(still connected though..so what's the point of taking it off)...OR getting an RTEK ECU and that Ecu will delete the OMP from the Electrical circuit so you can actually take it off.
Still though you need to address Lubrication..and that means Premixing.

Correct for S5's only.
^Correct for S4's only. The S4 manual gives a different test spec for turbo vs NA pump. Since you can't bench test the S5 OMP, the spec isn't given.
Also, the S4 has different PN's for the turbo/NA OMP. S5 only has one.
