I have what I thought are 2 1988 d16a6 motors, but both have different size crank snouts (where the pulley attached to the crank). One seems to be 22mm, while the other is about 24mm. Does anyone know what year d16a6 motors have the 22mm size? My problem is that the motor I am using for the car needs a pulley with a 22mm opening and all I have is the pulley with the 24mm opening.
I guess I can take this post one step further and say that if someone has a pulley with the 22mm opening, I am in need of it.

 

I was under the impression that only the D15 had a different size crank snout.

 

From what I have been able to gather, it looks like some of the 88 A6's had 22mm snouts while others had 24mm. Then from 89-91, I believe they all had 24mm snouts. But I cannot clarify this, so hopefully someone in here has the knowledge I don't.
