JohnRR said:I have the M21 trans and wish it were the wide ratio M20 with the lower 1st gear. Other than gear ratios, is there any difference between these two transmissions?
Not really. The biggest difference between the wide ratio and close ratio is the ratio spread between 3rd and 4th. The wide ratio will have a HUGE rpm drop from 3rd to 4th, where the close ratio is not that bad, which keeps the engine up in the torque band.
The M22 is a completely different animal, internally, with wider, straighter cut gears, that make all that loverly noise!
The wide ratio also has a lower 1st gear....2.56.1 to the close ratio's 2.20.1. Unfortunately, mixing & matching gear sets isn't possible with the factory gear sets, so you can't turn a close ratio into a 2.56.1 first gear trans...and that would be just about the ultimate set-up.
