Actually, nitrous systems can be relatively easily removed, so your
resale-value issue is a minor one. Turbo Magazine this month has an
article on an S4 with a nitrous kit, I think it ran 13.xx sec 1/4 miles @
~ 100 MPH. Not bad for a 4000 Lb 4-door sedan! Turbo-supercharging Vs
mechanical-supercharging are pretty much the same as far as changes to
the engine mechanical compression ratio are concerned. The reason that
you see a lot of mech-charger kits that do not "need internal mods" is
because they are running low boost levels that are safe with the stock
CR. You could do the same thing with a turbo, just run low boost levels.
Personally, if I were making the decision, I'd sell the 20V and find a
Turbo 20V and go from there.
