Broke Rear Diff on Evo5GSR can Lancer GSR Cm5a rear diff work?
I´m in the middle to put a new rear diff in my Evo, but my budget its too low
Here in my country I dont have many options, only to bring it a Evo 8/9 rear diff from USA but i like said, its expensive... Do you lnow other way to kit in my Evo 4 (rear diff ratio is 3.312). Maybe an Outlander rear diff?

Still works great after lots of drag racing and autox . Had to rebuild the motor twice, had to change turbo once, clutch twice, 3-4th shift fork , engine mounts, diff mounts but still havent had to change the GSR rear diff or even change the oil as yet. Still works great. very tricky to try to power slide with though...but ive managed to get used to it and even beat rally cars arround some courses.

Diff howling noise
I have a 98 evolution V GSR model with ayc. Rear diff is damaged and a used e5 diff costs $2500 in my country. I have a rear diff LSD from a 97 Lancer GSR 1800cc CM5a model readily available to me for free. Can this work? Also the previous owner has changed the final drive in my GSR gear box to the RS final drive 4.529 to 4.875.

I’m looking to buy this diff out of a CM5A 1.8 GSR manual, my Evo 5 GSR still has AYC. After doing some research, people say this style diff is the same as Evo 1-4 and Evo 5-9 mounting points are different. Can someone confirm it’ll fit a Evo 5 too?
