My ultimate desire is to have an aluminum block 2.8, retain traction control and change my diff ratio to something like the 3.15 that comes in the z3 2.8. Beyond that, the attraction to swap parts was physical as opposed to electrical and to retain some purity in factory design. Plus it was an approach I have not seen discussed.

So to put it another way, Jim (or anyone else)- if I wanted an aluminum blocked 2.8 with traction control how would you do it? What is desirable (Z3 rear subframe and diff?) vs. essential?

I think the 2.8 Z rear end has the single tab diff hanger that is prone to tearing so that would be reinforced.
