Whatever you do avoid using the M21/22 2.20 close ratio first gear transmission on anything less than a 4.11 rear, or it is a clutch slipping dog off the line for normal driving. I had my M21 swapped to the wide ratio 2.56 first running a 4.47 rear gear for a better take off. The only big RPM drop is from 3rd to 4th with the wide ratio, but by then the fun part is over anyway..
