1600 vs 1800 ? 
 

Try a search for the 1600 using the same year and see what they say.

I wonder if this is the turbo variant of the EA81 that you got over there but we never saw over here - except in private imports from Japan. 

Hopefully someone can shed some light on this!

I have a EA82 87 DL wagon and as noted, they have two different water pump pulley heights (because of A/C options). In my case, I found the pumps and shafts were actually the same parts between the two choices. The only difference is how far they press the pulley onto the shaft to create a long or short version. I got the long pump version before I discovered I needed the short, but was able to use a hydraulic press to push the pulley onto the shaft a little further and make it work, instead of doing an exchange through Rock Auto.

If you can believe the images offered on Rock Auto, there does appear to be two different pulley choices in your application. One pulley looks like it is slightly deeper than the other so it might not be like mine where I could "fine tune" the pulley location on the shaft.

Good to know Dave. No going back now for me though, if it still frays the belt some, I'm going to live with it and change the belt regularly.
