15 435i to 17 640i What mods apply to both?

Chaos236 · 03-12-2021, 07:29 PM

This board is much more active. Both cars have the same N55 engine correct?
Berger Motor Sports said my stage one tune will switch over.
What other mutual applications are there? Love to switch my original 19 staggered 435i wheels over? Car was salvaged with the 18 “ snows.
Thanks

How many miles does your 640i have?

I suggest to change the OEM N55 charge pipe before any other mods.

Engines not the same.
Suspension isn't the same.
Interior isn't the same.
Exhaust isn't the same.
Wheels are about all they have in common. Not sure what the 6 comes with stock but you wouldn't want to go to a 19 if it's stock on 22s or something. If it's 20 to 19 then you'll be OK.

I posted a reply to your original message in the 6 forum with a list of performance and cosmetic mods. Check it out! hopefully it is helpful.

Also, the pneumatic wastegate N55 that is in our 640i is similar but not totally identical to the other N55's (ours is the high output version with 315hp/335 ft/Ibs of torque; it's actually the same N55 in the M235i). However, the performance mods that are available to other N55's generally apply the same to ours in the 640i.
