I am a HUGE fan of trying to SC a T4. I have a plan for my 1.8 in the '74 and don't really mind if I blow it up.
I remember a supercharged pic on this site but it was some old. I have also seen a turbo one with ITBs and cannot remember where or if it ended well.
A friend picked one of these up at a PnP in S. CA this year for $85:

Then blow through some ITBs like these:

That SC whine just behind your head...oh my!
Probably a dumb idea but it might be fun to try.
