Thumbs up M6 xDrive? 0_o (from GC 650ix to M6 xDrive)

Hi there!)
I can tell you story about building of my tuning project, if you are intrested.
Sorry for my engilsh, i just learning, so i can make mistakes in my spelling))

I bought this vechile as bmw 650i xdrive grancoupe over 3 years ago.
Now it is hybrid from 650 to m6 and x6m f86.
Exterior like m6 f06 , but i dont have back side mirrors and carbon roof from m6.

Stock motor n63tu builded with sleeves , carillo's rods, ppm's pistons, crankshift from s63tu.
Head, exhaust manifold, dme, turbos, dsc ECU - from f86
Tuned camshaft
Tuned fuel system (fuel ramp, pump in the gas tank, fuel ECU)
Cooling m6 f13 (all radiators) and f86 intake intercoolers
Intake m6 f13
Methanol aquamist + aem
Automatic gear from f86 (zf 8hp75)
Gear selector from m6 f13
Dashboard from m6 f13
Electronic steering rack (from 528xi f10)
Reducers 3.15 (front and rear),
Exhaust m5 f10 with catless downpipes, without muffler, and custom back with volume regulator (from remote control)
Brakes m5 f10
Cutted off dynamicdrive and classic stabilisators
Now it has 815hp/1150nm (best results up to 1260nm), or 690wheels hp.
100-200 km/h it rides at 5.91 (result on snowy road, from 4th gear), prognosed result 5.6-5.7 (on dry road and from 3rd gear).

it is very difficult project with big cost - over $100000

Results from summer 2018 (720-740 engHP, without meth, on old reducers 2,81 etc):
0-100: 3.1
100-200: 6.5
1/4: 10.8

Now we cant make new rides 0-100,1/4 cause there are winter in Moscow, but we maked ride 100-200 and get 5.91sec

I hope, that in 2020 season i'll have next results:
0-100: 2.7-2.8
100-200: 5.6
1/4: 10.4-10.5

WOW! That is an ambitious project! It take big balls to take on something like that, but it is a cool idea, and those are some impressive numbers.

Wow, that's super impressive. Congrats on being able to accomplish all of that. How hard was it to integrate the DSC ECU? Does that significantly change the cars behavior?

i dont make it by my hands, but, i think, that wasnt very difficult.
We made this upgrade for better launch control from 2.9-3k rpm without dsc-errors and car stopping

Hi Sib. I follow you since few months on instagram and drive2. It's good to see you there. Wouldn't be easier and cheaper to buy M6 and swap xDrive instead of swapping all parts from M6 to 650xi?

Hi! Thx!)

No, there is no way, bro(
There is no transfer case for DCT.
There is no software.
The engine is located below and a different shape of the engine tray, so it is not possible to install the front reducer

For example, f85/f86 and newest f90 are using 8hp75
