Thread: Distributor rotors, as in plural

So, I ordered a new cap & rotor from RockAuto to freshen up the SE-L and low and behold the rotor doesn't fit. So I do a little research and it turns out there are 2 different styles of distributor rotors for the DE. One with a big socket (22157-0M512) and one with a small socket (22157-0M513). Of course, I needed the big one and got the small one.

Apparently, Nissan screwed up the FAST listing and all of the other parts stores passed along the error. Have I just been living under a rock and this is common knowledge?....or is this the first time folks on the Dash are hearing about this? I see GSpec has them both listed on his site, so I'm guessing I need to remove the boulder....lol

I only managed to find one thread on the issue from the old forum. Distributor rotor question - SR20 Forum


Hopefully, this thread will save others the hassle of returning parts or just eating them. I couldn't find any info about this here on the Dash.

Always used greg so ive never experienced this ...

Well, either I have a swapped dizzy or Greg has them listed incorrectly.

This is the one I need (listed for a B15, P11) (22157-0M512) :
Rotor, 2.0, up to 01/01, OEM Ditributor Rotor



The following are the 2 that are in the 99 Sentra tuneup section.


This is tagged as "Rotor, 2.0, 95-96 (P10 from 1/94 to 3/96)" (22157-0M810):
Rotor, 2.0, 95-96, OEM Ditributor Rotor



This is tagged as "Rotor, 2.0, 97-99 (P10 from 3/96, B15 2.0, from 01/01 & P11 99 & from 11/00)" (22157-0M513):
Rotor, 2.0, 97-99, OEM Ditributor Rotor

22157-0M513 is not correct for my dizzy. Like I said, I'm not sure if the dizzy is original to the car.

Does the rotor have a screw to tighten down on the shaft?

I only have experience with OEM highport and OEM lowport but that is the difference that I know between those two.

The highport has a screw that tightens to the shaft to attach and the lowport kinda just "pops" onto the shaft.

It just pops on.
