Ur-Q Intake Air Boot

[Ben Swann]

While installing an MC engine from a 5000 turbo quattro into an early coupe GT you realize they sort of had to do it this way or come up with some other convoluted hose routing.  In the 5000 there is plenty of room to brin the intake hose from the fuel distributor down to the turbo by going in between the intake manifold and the air-box.  In the CGT, there is simply no room, unless one does some interesting hose routing.  There is  a small area of about 2"x2" to squeeze a pipe down just behind the lights.  

The aluminum igloo is fairly compact and the pipe goes directly down into the turbo - short pipe, less drag - actually it is ideal, as long as you have the urq parts - need the fuel distributor(installed backwards from 5000tq - 5kt will not readily fit), UrQ plastic airbox frame it mounts on( CGT/4kq will not fit), aluminum intake igloo, 2.25 i.d. exhaust piping works well to connect everything up.  You'll need to intermix injectors and lines between both setups for the optimal configuration.  

I need to do the writup on this car, as it was not trivial, but the install could have been more straightforward had I had all the information I needed before hand.  Supposedly similar swaps otheres had done into 4000Q only led me to doing many jobs over.

The UrQ intake "boot" is actually an aluminum piece.  The whole
air flow metering unit is actually installed "backwards" compared
to the NA cars.  As for why it is so, my guess is because that was
the first (and only) production Audi with a turbocharged I5 in the
type 85 chassis, and that's the way Audi made everything fit.
