How old is this late model Audi? Now $50 for a turbo is great! Just check it
before you buy it! You can remove the hoses from the compressor wheel opening,
now move the shaft around, it should have barely any play if none at all. The
bad new is most Audi's I know of have K03 trims only good from low end power
and 8psi range, yes you can run at a 14.7 max but it wont be that efficient. I
think you will have better luck going with a supercharger on that truck. Now if
you can get a twin turbo setup and lower your engine compression and like to
drag race go with the turbo's.

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?

And where are some good sites with info on turbocharging?

I've been thinking of this all day, man am I excited :) But if I can do it I am
going to do it right and plan EVERYTHING out in advance. Thanks for the help
folks...
