Are they V12's?
Yes I think so.
Its 840i old are 4l and newer is 4.4 v8 same as e38.
850i are v12 5l same as e38 and 850csi is 5.4 I think and thats got 380bhp or something and a noise to die for.
Edit I think the 850csi is a 5.6.
Might as well do it properly and put a VQ37VHR in it Would be ~350HP (NA tuned) in a pretty light car
Either way. Most people put Rb25's or stuff in and I think the engines are too heavy personally plus I love N/A.
:lol:thats why mine has got leather.
I dont see why peeing wouldnt work. Car gets dirty anyway
But seriously though if your petrol cap was stuck spray deicer or screenwash on it. Not water as it will freeze again! I can remember 1 day 2 years ago it was about -16c and water was freezing solid as soon as it touched the car. Even deicer was getting slushy. Now I'm not saying it that cold but just dont use water.
+1, or pee on it.
I usually see AMT250 then read the thread. I put water into the screenwash this morning but not sure as it wasnt volvic. Does that mean the car will blow up?
Using proper rubber has its own problems though like if you use slicks then you need a way of getting them there and back. Also r888's are expensive and only really work well when hot. You will also most likely need other things like a baffled sump etc etc.
