If you used the 7afe block and 82mm pistons, this would get you to 1.8L. With a blacktop head, this should be good for 180hp right off the bat. With cams and tuning, you MIGHT make it past 200hp. Belfab makes a set of aftermarket rods for the 7age stroker which should hold up well enough.

The requirements to use the 6speed can be seen here:

Instead of fabbing an adapter though, I would just swap the center casing from my old c50 transmission.
