Nizope. It won't even hizook up to your car. The mizount points are diziferent. You would have to replace the rizear sub-frizame with that of a 6cly and then figue out how to make the drive shaft hizook izup. Fo'Shizzel (sp?)
Yes, it would I was looking into doing the swap myself. However, there is another possiblilty if you are serious about doing this. It looks as though the internals of an E30 would fit into the 318i diff. So if you can find a diff guy willing to work through it... it would be cheaper...
$400? it is going to cost a lot more than that to get everything together to put a non 318i diff on the car. The only other diffs that bolt right up cost over a grand from aftermarket. I figured it should cost about $500 dpending on how much they charge you to do the labor.
You would have to swap just the subframe. The brakes ect for the rear should be the same... I think... not 100%. However, the problem is that the 318i driveshaft won't hook up nor will the 325i or the 328i driveshaft hook up either. So you will have to pay some one to custum machine one or the other to make it fit. Once I heard that, I stopped looking into it, so I am not sure as to which of the driveshafts will have to be machined. Or perhaps a whole driveshaft will have to be special made to make it work...
The diff will accept that drive shaft, as long as it is the same length. But I believe he said he has the whole rear subframe, and if the car you own, and the donor car are both automatic, or both manual, it should work. I think where you would start to havet problems is if you tried to take a manual driveshaft, diff, etc. and tried to fit it to an automatic tranny, or did the opposite. In any case, you should be able to ask the mechs at your local bmw dealership. At least in my case, they always seem pretty helpful.
