[120Owner]

Hello,

Sorry if this is a double post; it's my first post here and I'm looking for a bit of advice. I originally didn't get the 125 because of insurance cost (it was about 2k more) but now I'm a little older I'm looking at trying to cover the gap. For very personal reasons this particular car means a lot to me therefore I'd rather spend more than it would cost to sell mine and buy a 125, converting the car.

I know for sure that my 120 is twin scroll turbo and that the 125 is twin turbo. Now could I just swap the turbos on or are there other parts I definitely 100% need to swap on too? I also assume that I'll need some kind of remap?

Thanks

P.S. I would plan on using genuine BMW parts for this
