I want people to contribute... that way we can figure things out.
Having multiple build threads means that it's hard to keep track of where all the good ideas are. I started this thread to try to keep everything in one place.
I had spent exactly zero time thinking about axles in a serious way. At the worst, I can have custom shafts made with the E53 inner spline on one end and the E30 outer spline on the other end.
However, finding a bolt-together axle setup would definitely be more desirable.
One thing I just realized. Since both 6 and 8 cylinder E53 pans put the diff in the same place, a 6 cylinder E53 swap would have to do the same thing with the steering rack as I'm having to do with my 8 cylinder swap... There will be some interference between the stock rack and the E53 diff.
The major question of fitment for the 8 cylinder is whether the rear face of the left head and the front face of the E53 sump will clear the brake booster location on the firewall and the suspension crossmember, respectively.
The S62 does not have the rear coolant crossover that the M60/M62 have, so it can--and due to the oil pan MUST--sit back further in the body than a BMW V8 would in a RWD E30. This means that there will likely have to be work done to the trans tunnel to clear the dual starter bulges on the M62 bellhousing.
However, the passenger side of the E30 firewall is further back than the driver's side. I think there will end up being adequate room for a 24V engine, even though the 8 will be extremely tight.
