thinking of swapping F32 440i for E89 Lci i35s...queries

hi folks,
i'm finding my 2016 440i to be, to be frank, a bit boring - and here in the UK i could get a 2013 i35s with a few grand in change....

got some questions though:

- the iDrive unit is an older version - can this be swapped out for one of those touchscreen Android jobs, like i can in the F-generation cars? (a pro Nav style unit)

- how does the N54 twin turbo compare to my B58 for tunability/reliability?
i know the B58 is still relatively new but its easily mappable to around 400bhp - can the N54 be mapped to a mid-level tune without much effort?

- does the car come with LSD or can this be added later?

i'm going to test drive one at the weekend - i'm hoping for better sorted suspension, better body control and something that's altogether a bit more 'sporty' than my current car!

thanks!

Hi! Stock 35i for me was boring too. You should add new suspension(i have ohlins and i recomend it),stage 2 for a little more fun and finally you should upgrade the brakes. Then you will have a lovely toy.

The B58 is nowhere near as tunable (at this moment) as the N54. The N54 is being called the new 2JZ across the internet. You’ll run out of money before you run out of tuning possibilities/upgrades for the N54 😂
