Hi guys,

Recently blew my ayc diff in my EvoV. Been a headache trying to get it rebuilt.

Considering RS diff swap but just have a few concerns:
1. Any idea what type of diff this is (open or lsd) - part# on the diff mr145011.
Automotive tire Motor vehicle Bumper Automotive exterior Wood

I believe its evo 4 rs but not sure, seller says for 5/6's - the kit include mounts and axles.
Gas Wood Household hardware Metal Tool

2. Will the ratio of this diff work with my stock E5 gsr transfer case without issues or modifications ?

3. is there anything else I need to be aware of if i was to undertake this swap, i.e AYC ECU needing to be ripped out.

The ayc unit on my current diff is fkd, so been a mission to source. Wondering if this swap is worthwhile without too many other things to taken into consideration.

I'm pretty sure it's not a E5 or 6 Rs diff : the 2 front mounting brace are different on a 5 or 6 RS :

White Human body Organism Art Font

Water Jaw Sculpture Wood Gas

(this one is from my TME RS)

maybe a 4 one, but I can't say if it's bolt on or not ?

good luck
