Brother EPS unit was of Japanese Alto, it required min alteration and when fitting was done, no one could tell by looking at the steering column that any alteration is done to it.
My steering wheel is even better than before the EPS, it's very soft till 30Km/h, and start getting hard after that, on and above 100 it feels slightly harder than normal mechanical steering of cultus.
I read nearly all the threads on PW related to EPS installation in cultus and i told all me concerns to my mechanic, although bilal gunj guy offered to install the EPS in 10k (7k for EPS and 3k for installation) and he told me it will take 2 hours, but my mechanic took almost 4 to 5 hours and charged 11k for it, and in the end i very satisfied.
