Hi i own a volvo v70 2012 drivE i currently have a 4 cylinder diesel engine i was wondering if i could swap that engine to a d4 if its even possible and how

 

anything is possible, particularly if the chassis already supports the new engine in some other model. The complexity is really with the wiring and computers so a swap would have to include the block, accessories as well as the wiring harness and related computers (ie the ECU). Then you have the problem of making the computers talk to one another which will probably mean you need a tool like VIDA-DICE to pair or reprogram some devices. At the end of the day, its more sensible just to sell your car and buy a new one that has the features you want. That's assuming you want a street legal daily driver. If you were building say a rally car you'd probably junk everything other than the ECU and perhaps the TCU if you were keeping an automatic
