What size sprocket should i use for a fireblade engine also which diff is best, i am thinking about using a sierra diff but they are getting a bit hard to get hold of. Ant ideas welcome.

If your using chain to drive any sieera diff will do, there must be lots of the unpopular ratio ones about, your not limited to sierra either, any diff where the crownwheel unbolts will be suitable, just get hybrid d/shafts made, mine have fiesta inner joints (fiesta diff) and sierra outers

The Fiesta / Escort diff is a popular option. I have the Quaife version of this. I've attached a photo of it during the build.

Sprocket size should be determined by yor wheel size and what you intend doing with the car.
