I am quite interested in learning what others have managed with this
engine. Has anyone seen a twin turbo Alfa V6? Would such an engine
require extensive transmission upgrades? Is there a book out there
that can answer my questions so I don't have to annoy you all here?
The twin-turbo thing has certainly been done. Most famously and
CA-emissions-legally by Reeves Callaway in the '80s. More recently
by Banks in England (albeit in a non-Alfa application). Beninca in
Australia may have done a twin-turbo V6 as well, but they're known
for their Alfa 4-cyl. turbos (as is Jim Steck here in the USA). I
know it's been done by others too, whose names I don't necessarily
know. I'm sure there are more than a few crazy Alfa tuners in
Germany or the low countries who have slapped a pair of turbos on a
V6.
