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.

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

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 :

(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

That is a CM5A/CM2A Lancer rear differential, I have a couple here in Jamaica. It uses the same diff housing as the evo 3 and the ratio is 3.312(I opened mine and counted it myself).

I am using it on my cs3a lancer awd conversion

Mine installed. It's an open diff btw but an evo lsd differential fits perfectly inside.

its defo a 3/4 diff ,a 5 onwards is totally differant ,the shafts if 4 are worth quite a bit as there VERY rare ,,it will fit a 5 tho ,depends how much it is ,if its worth doing

thanks for the input and info all. Ended up going with a rebuild evo 8 ayc diff with ratio's to match the evo 5 gsr.
