I understood you. As I said they are all The same inside. The only improvement in the strength your gearbox really claims is that 3rd gear, though the cooler is a nice upgrade in durability with heavy track use.

Hello experts,

regarding transmission:

i am looking for measurements of the standard ring &pinion...

the outer diameter of the crownwheel and the total lenghts of the pinion

inches or mm (or both) are okay

I know a factory in Germany, they could do a 3,75:1 set, but they need to know
the measurement of the series items for calculation-purposes

Both Matt and Bill are by any measure, transmission "experts"....maybe they don't have that info at their finger tips. Cheers

What is the value of a 993C4 gearbox these days?
Or a 993TT gearbox?
