There is pictures of similar solution in this board. "Skarvsladden" or something like that has done it for his ix. Gears are from another diff or you can even buy them new from BMW.

Did quartermile in 10,3s @ 226km/h yesterday with 100% street setup (street tires (nankang ns2), street springs and dampers, street alingments). Finally the stock gearbox broke. Third gear missing now. I think I'll update it to 525ix box (same zf as e36 m3 etc).

Some numbers from engine management log:
0-100km/h 3s
100-200km/h 5.6s
max rpm 8430rpm
max boost 1,5bar

So still with lowboost setup. Will raise it as soon as I get my fuelling updated. 1200cc injectors are 100% open now with two walbro 255lph.

I get goosebumps everytime i look at movies on that car
Awsome!!

Little acceleration with lowish boost (2bar) and slow gear changes. Trying not to break everything:

Nice to see this one on the move again.
What changes have you done?

Mostly cosmetic changes. Bodywork pretty much all new + new paint.

Technical side - new fuel system and new exhaust. More boost and more revs.

Awsome!
Still big smile When i see the clips hehe
How musch power do you have Know??

Don't know for sure.. Fact is that engine is consuming 20% more fuel than in the best 1/4mile run (10,3s @ 226km/h). I'm guestimating little over 800hp.

It sounds so fucking awsome

Wow thats impressive, same driveline still?
Hope it holds for me to When i get to those Numbers hehe
Any pics? World be nice to see it close

Still with lightly modified stock drivetrain. It seems to hold ok, but it cannot take any clutchkicks. I've Limited the torque down to ~700-750nm. 800nm is pretty much absolute max what it can take. Over that and you start breaking stuff with straight torque (front diff, flex disc (between trans and transfercase), transmission, rear driveshaft flexdisc).

Here's few shots of the uncompleted car:

Great looking car!!
Exactly the way i want my car clean!

Nice to hear it works with that much power, i was worried about how much it can hold but hearing it from you makes me Wanna buy a new turbo for next year :p
What clutch do have?

Thanks!!

Clutch is sachs -765 + 240mm sinter disc. Maybe something twin disc organic/carbon could be easier on the drivetrain.

Ok what gearbox do you have?
Thought you had org 260?
