This thread is just full of jokers!
In all seriousness OP I would recommend a few things:
6 pack of HPFP.
A set of the new updated turbos
Enough plugs to change them 2-3 times along the way, better throw in some coils also.
And if you think I'm joking consider this, I have an e90 with over 110k on it and my trunk looks like a BMW parts store and I never drive more than 100 miles round trip. These cars these days are utter pieces of shit.
Hope this helped.
Goodluck with your travels!
