How many different pinion gears are available for the zetec FD upgrade? Is there a way to measure the output shaft inorder to find what size we will need? Can we take the numbers of the tranny inorder to find the one we need?

How much HP would one consider to be enough to do the swap if the tranny will be open anyway? 250-300 at the wheels?

I may be doing this in a 99 tranny.


Thanks.
