Turbo interconnectivity?
 

Greetings!
I'm looking at upping a T2 to a t28 (no arguments to be had there l expect :D) One thing does bother me, its the exhaust manifold connection.

Is it the case that there are only a few types/patterns of connection (a common one being 4 bolt square flange)
and if these are the same from a donor car you are pretty much there?

Yours with ignorance. ::)
