I ended up blowing up 2 x M20 Boxes,within 2 years in the LX when I first bought it and it was only a (Mild) 308 both of them striped teeth of second gear!!,do yours still use the standard Gears??

ryanHAhaha I wouldn't bother with a m21
some of us with original factory standard cars have no choice!
other than those lucky ones that had dealer fitted T10's
have to treat the old M21 gently these days

Aussies are delicate in the lower gears regardless of horsepower.
They are simply not strong enough in the cluster/layshaft bearings.
BUT..................they are cheap to repair.

that's why we use the ford top loader lay shaft and rollers its much larger and makes the box tougher
see we bore the cluster insert steel sleeves and bore the case see this modification makes it hold up to 355 stroker
I have not had a race box come back yet .....
