56T is for 32p gears, a conversion will use mod1, which gives you 36, 38, and 40t options. If you specifically want 32p gears, you may be able to fit a 54t on there since 54T @32p is roughly the same diameter as a 40T @ mod1.

What gearing you choose depends on what you did to the tranny. Are you keeping the two speed? If so, you can gear higher on the pinion since first gear is quite low. If going the single speed route, which ratio you chose to install inside the tranny (close, normal, wide) can make a difference. In my conversion, I used the tranny locked in second gear with the wide ratio gearset, 40T spur and 14T pinion. Can't remember the top speed but it was perfectly fine for track use.

Hint: when using the calculator, enter in all your values, and when you calculate the speed, an icon will appear (looks like a set of gears). Clicking that will bring up a table showing theoretical speeds at various pinion tooth counts. The bold one will denote a 1:1 ratio value, which is a decent starting point for a combination of decent speed and cool temps. From there, you can play around and see what works best for you.
