How to make the right Mercedes-Benz SLR McLaren in 5 (not so) easy steps

As I mentioned in an earlier post I am not impressed at all by this car. The reason for remembering it was that one of the major drawback was fixed, not by MB but by Ferrari in the new F12berlinetta. No, it's not the engine, it's the gearbox, one of the problems mentioned in the earlier post. This double clutch gearbox is the closest match I know to the SLR specifications.
So let's make a proper super-sport GT.
1) Buy an SLR, preferably with a broken engine and gearbox.
2) Ditch the gearbox, drive-shaft, differential.
3) Mount the new Ferrari F12berlinetta transaxle, if you can buy one.
4) Ditch the engine compressor and the water-to-air intercooler system.
5) Mount an IHI compressor from AMG 32 engines and two turbocompressors which should generate around 1 bar (14.5 psi) of boost and two correctly dimensioned air-to-air intercoolers.
If all works well you will end up with the right SLR, the power numbers should be around 730 HP, and the weight should be 100 kg lighter.
For extra points you could do some extra steps:
6) Change the injection system with a direct injection one.
7) Convert the engine(cam profiles etc.) to run in Miller cycle.
These should lower significantly the fuel consumption and might also increase the performance.
Looks quite easy, isn't it?
