This is a bit of a hyperbole. The only difference is how the motor mount attaches. The N55/54 subframe has the two bolts for the newer style "tall" motor mounts, and the S65 subframe has the single bolt style mount that RWD bimmers have had since the E30. I would definitely suspect the S65 could be made to work with the N55/54. Everything else is exactly the same, suspension mounts, steering rack mount, etc.Totally different but both frames will bolt up to the chassis with no modification.
No, I'm not. there are exactly two major physical differences in the subframes. The type of the motor mount and the rear "wings" on the V8 subframe, which we know doesn't matter. Other than that they are exactly the same size. The only other difference I find are the mounts for the brace on the V8 subframe.Your forgetting about the sump position and the position of the mounts, I dont think it would be worth the effort something a custom brace could not fix.
Good point. I'd bet a custom exhaust could be made but I like I said previously, I can't see it being worth it.No you could not, the down pipes will hit the s65 subframe as we already tried.
You could possibly make the n54 subframe work with a v8 but not the v8 with the n54.
Look at the passenger corner closely just behind the engine mount.

Back to M1.5 talk please.
Yes please, how is it coming!
(I like to hear about both setups and I lust after having a V8/M3... but I want to see more of this swap!)
That's what I figured. I don't think it's going to fit behind my 135 fender so I may relocate it to the battery compartment or something. Thanks!I reused it and running it same way the m3 did everything is just the same and fits. I used a rubber hose clamp to mount it under the guard.
You need it all the time as it supply's vacuum to the brakes in low vacuum conditions unless you have a full racebox pedal setup then you won't need it.
These engines don't produce enough vacuum especially when your punishing it through the curves
