Has anyone installed the Synchrotech MK-EVO67 master rebuild kit for EVO 6/7 on an EVO 4 transmission? The kit includes the Pro Series 1-5 carbon synchronizer set, 1-5 synchronizer springs, 1-5 sliding sleeves, reverse synchronizer and spring, shaft bearings, and seals. Does anyone know if any of these parts will not work on an EVO 4 transmission?

I would ask them they will likely know. Doesn't hurt to post as you did to see if anyone has tried this. I appreciate the post since they offer the 9 rebuild. By the time I need a rebuild Mitsu will have discontinued all of the parts,

 

Yes, I asked them and they said they weren't compatible, but I saw that Jacks Transmission sells the kit for Evo 4 to 7, so I have doubts.
