as far as I know and I'm sure I'll be corrected on this but the V8's were the first year that they introduced the twinscroll setup being the VF37 is for the standard STI and the VF36 is for the Spec-C (titanium shaft and more goodies) from what I further understand these turbos spool at least 500RPM faster than a 34 would. They do NOT make as much top end HP but the TQ is amazing.
STI V7 came with both small port and big ports depending on the heads that came with them. V8's all have big ports.
I believe they are the same internally other than the things mentioned above.
I would love to eventually get a twinscroll setup but that's after I play a little
