To give you a short answer, no, it is not the same, a supercharger is belt
driven and will give you somewhat predictable boost according to rpm. A
turbo is exhaust driven, and will give you varying amounts of boost
according to how much, how soon, and how long you will have your foot into
it. A turbo requires an engine management system (holley, $1800) that can
control the engine's normal needs for fuel as well as fuel for differing
amounts of boost. It can be done easily if you stick with a fuel injection
system that can do this.

> Not the question you think though. I was scrounging through a decent
scrap yard today and low and behold I find a late model Audi with a bent
frame and trashed body. Hop onto the engine and look inside and what do I
find but a turbocharger set up with only 50k miles on it. I asked the yard
guy what he wants and I can get a the complete set- up for $50 :)

> My question is, how is a turbo charger install different from a
supercharger install? It seems to me that most SC (except the Kenne
Belle's) are basically bolt on mods. A lot of folks dont change the PCM or
anything else even, just get a longer belt and open up the exhaust and off
you go. I am thinking find two identical turbos, one for each side of my
V6. Of course I will have to have someone fab up some exhaust for me, but
what else?

> Do turbos, specifically those found in stock Audi's, pump a much greater
pressure than a supercharger, so that it would neccessitate a stronger
intake setup to the TB? And where is the optimum power band for these
chargers?

it I am going to do it right and plan EVERYTHING out in advance. Thanks for
the help folks...
