Neu$peed TB = A2 TB = Audi 5000 TB. No mods to the TB
are necessary except to use your TB old linkage (swap)
and swap in the old TB idle adjust hex screw.

The intake must be port matched to the TB. Otherwise,
you will gain about 0.0 hp.

Even with the matched port, it will give you maybe 3
hp (according to dyno tests). So . . what's 3hp worth
to ya?

If you are talking about P&P, IMHO, this should only
be done by a pro. You can port match it yourself to
the bigger TB if ya got the tools and such.
