my Z3 coupe

An update from the mighty Z3 coupe.
Christmas time and I run into a small problem when the crankshaft sensor stopped to work and also the idle control valve complained.
The engine would not idle and it was working very bad.
I decided to take out the intake and check the bits underneath and replace the crankshaft sensor.
8 hours later... I managed to remove the fecking intake (I also checked sparkplugs etc). The limited space of the Z3 engine bay made everything so difficult and was swearing for about 5 hours.
There are so many cables, plugs, pipes etc underneath this intake.

Then I discovered more issues as the throttle butterfly hose had a crack/hole, some other ventilation pipes (there are many) were broken, a pressure regulator was broken etc.
I ordered the parts and in about a week they were delivered.
I put everything back together (took my another 3 hours) and turned on the engine.
Problem's solved !
The holes/cracks in the pipes and butterfly hose had affected the amound of air flowing in the intake / which was not the same tha the MAF was measuring.
Instant results : 1lt/100km less consumption and much better performance throughout the band

At the same time, I removed additional unnecessary weight from the boot and shaved of another 15 kilos.
I also weighted the car with full tank -> 1230 kilos.

I have spent about 15-18 hours drifting in the snow with 3rd-4th gear in some interesting places close to where I live.
I have to say it's more difficult to drift compared with the CSL as it's much shorter, but I have mastered it

Next test will be 14-03-2011 in a racetrack in France. I will go with the same shitty tyres but want to see the difference the spacers will make.
If it's raining, I will get some cheeky videos from the drift action
