Convert 120D to 125D
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 |

One way to find out is to spend a lot of time on realoem.com and check every single part to see if it's different between the 2 engine types. (Like already said; turbo, injectors, exhaust, pistons, etc etc)
And yes, the engine management will have to be changed. But you might be able to flash the ecu to stock 125D if you actually do a complete "original parts upgrade". Isn't a complete engine swap (rebuild or lower mileage) a better option? |
Appreciate
