Hello everyone,
I had a 335i f30 Xdrive 2014 (N55 EWG) for really cheap, as I like challenges and originality and also I have the possibility to get an M3 F80 engine (S55).
So I intend to swap the N55 for the S55 but keep the Xdrive and the ZF8 gearbox and reflash it with XHP.
I have several questions:
-I'm going to keep the oil pan from the N55 and put it in the S55 but I'm going to have to remove the secondary oil pump. Is there any way of keeping it?
I have heard that the DMEs are very similar and that many of the tables are common and that it is possible to activate or deactivate the options in the tables depending on whether the engine is the N55 or the S55.
-Can I use the DME from the N55 and plug it into the S55 so that the car still thinks it is the N55, if YES:
How do I manage the two HPFPs on the S55, should I replace them with a single HPTF (B58 TU with a custom plate)?
-The same goes for the water pumps, can I delete the electronics and keep the mechanical pump only?
-If I use a 2015 Alpina B3 DME can I keep the twin turbo or will I have to use a single turbo like on the original N55?
-What about the drive-shaft, can I keep mine or retrofit the M3's? Will I need to modify the DME?
-Can I also retrofit a virginised M3 cluster?
If the DME of the N55 is not pluggable on the S55, what would be the best solution to keep things as much OEM as possible?
Thank you in advance
