Mazdaspeed 6 diesel transmission gear swap

Hello guys long time owner originally from mazdaspeedforums

There used to be info about swapping out the internals of mazda's 2.2 diesel. The original post of there cannot be accessed anymore and I searched here and didn't find any info regarding it.

If anyone knows which year model of the 2.2 diesel transmission we can used and what work needs to be done would be great.

 

I recall something about having to mill down the input shaft in order to mate it to the 2.3 disi

 

Correct.

And if you're not making 500+ ftlb of torque, you're better off just swapping in gen pu gears. The diesel gears are too tall for most builds to be quick

 

Didn't someone offer a custom set of years that split the difference between the diesel and pu gears

 

Sp63

 

Sounds good. I'll look in to SP63. Also do you guys remember what year range was the compatible diesel transmission?
