Good morning everyone,
I’ve been researching the EVO VIII / EVO IX rear diff (Part #: MR166619) swap for my Time Attack prep’d 2G. In the process of doing so I’ve developed a few questions that I would like to pose to the DSM community. Here are a few links on how perform the install and applicable part numbers for the swap:

www.ca.dsm.org/forums/ubbthreads.php?ubb=showflat@Number=424987
According to the following table (vfaq.com/mods/trannies.html), the rear diff ratio for 1G, 2G, and GVR4’s are 3.545 (39/11). I’ve checked this across several other posts and this seems to be an accurate statement but if this information is invalid, please provide me with a link for all of our knowledge.
This is doesn’t seem like it would work, as the EVO 8/9 rear diff. ratio is 3.307 (43/14) (www.mnasz.hu/letoltes/mitsubishievo_infok.pdf), which would cause the center differential to compensate for the new rear gearing.
Admittedly I’m not a Drivetrain Engineer but can some please clarify how this doesn’t cause excessive wear on the front/center diff?
Thanks in advance!
