By request, i've compiled these. By no means are these definitive. These are just recommendations and do not need to be followed to the letter.
Naturally most of these stages are biased to what the vendor has for sale, so some stuff is missing. Driveshafts, different brand turbos, clutches, etc.etc. Feel free to use these as a guideline and edit as necessary for your application.
