13B oil pump
This is for you guys with the Rx-4's, REPU's (and anyone that has experience with the older 13B's) ...
First of all, what size is the oil pump of the '74-'78 13B motors? Secondly, does the oil pump from the Rx-7 GSL-SE fit the front housing of the "old" 13B's?

Sorry ... looks like I've got water on the brain tonight. I feel so dumb!

So, okay ... for the next clod (like me) that wants the info, here it is:

The older oil pumps are 15mm, and YES, they can be upgraded with the SE's 17.5 mm oil pump.

True. I've got a 17(.5?)mm pump ready and waiting for mine. Or it'll be going into a 12A.
