05 Mazda Speed Oil Pump Gears

Are these the same dimensions as any other oil pump gear? A Mazda tech told me the part number was different from the rest, but I don't know if that means its a different part, or its just an old part relabled for the MazdaSpeed Miata.

I just looked at the 2005 part diagrams. All oil pump related part numbers for the MSM and the regular '05 are the same.

The only oil system related difference is the OEM oil cooler, but we already discussed that elsewhere.

P.S. and the pipe for the VVT of course (which the MSM doesn't have)

Btw since talking about the oil pump of the OEM turbo Miata, has anyone looked into the oil spring Mazda made for the rally/competition version of the Mazda 323 GTR? IIRC Mazda have those in stock and the price was $10 vs the regular $2 springs.

B6N7-14-116, Spring, Oil Pump, Oil Pressure 6kg

Quote:

The revised edition consists of parts previously introduced as well as new engine parts. All the parts listed in this manuall meet Group N and A standards of the FISA international sports code.
These rally parts have inherited the quality performance and rugged durability from MRT (Mazda Rally Team) rally vehicles.

How does that spring compare to the stiffness of the OEM one in the Miatas?

P.S. I just ran a search on m.net and found some very old thread where people talking about this spring and the standard Miata one which is supposed to be 5kg. Someone said with the rally one the warm oil pressure goes up to about 90 psi. I guess noone posted the part number back then but here it is now :)
