Has anyone ever actually attempted an M60/M62 swap on an iX?
I found this kit, which is what makes me curious:
It's a bellhousing adapter for an M60 to M20 transmissions, and they sell a flywheel and clutch to go with it. That solves the most complex problem of the swap, in theory.
The next challenge is the oil sump. The M60 is front sump, which is most likely going to land directly in the steering rack by my estimate, but as I don't actually have an M60 or any measurements, I don't really know. Curious if anyone does.
There are a couple potential solutions. The E53 X5 has a different oil pump that moves the sump rearward a bit, but not quite a rear sump. My simple guesswork isn't that promising for it, though. The other option is a dry sump system from VAC:
A bit pricey, but it does completely solve the sump clearance problem.
Are there any other dealbreaker clearance problems? I know the strut towers are in a different spot, but I don't see that blocking anything. A remote oil filter is basically required, but that's easy enough, tap the block, run AN lines. I know the iX puts the M20 a bit higher up than a regular e30, but I'm not sure that that would require the M60 to sit higher. If it does, is it enough to require significant hood modification? Still not necessarily a dealbreaker, but a question regardless. Exhaust would be tight but I think it's doable.
And of course there's all the usual M60 swap requirements, ABS delete, booster relocation or delete, etc. I'd prefer to keep the booster and just move it up front, maybe put in a smaller booster from a different model.
Any thoughts on the actual technical limitations welcome. Also, any good sources for physical dimensions would be great.
