Hi there, This is Amir, I'm having a trouble here, in Iran, BMW has dealerships and official repair shops,about 20 years ago, BMW 6 series was introduced to the public but only 630i was sold here, I'm gonna buy a low mileage 630 E64 but I don't like the 3L straight 6 engine, Is it possible to swap BMW S85 V10 engine on 630i?
How much do you guys think it will cost to do so? What parts should be changed on 630i to replace the n52 with S85?
