[Es2] RS2/ES2 intake & exhaust source/fabrication

I did order piping to fab my own.  I'd like to take you up on using the pressure pipe to
clone as that sounds like what I'm trying to replicate even though I have not seen one.
3B is close, but I can tell it is not exactly right.

Did not know about the group purchase or would have probably gone that route.  Now I
have spent the money on some top qulity piping and adaptors, so will use these.  It
should look beautiful as well as be strong.

I still don't know if I'm going to use an airbox or a cone filter.  I could probably use
the airbox  - trying to get a clean almost stock look except the pipes will look more

I am using RS2 intake on AAN head along with IA EM.  Turbo is RS2 and intercooler is
from an RS2 and using core support with integrated crosspipe.

Why don't you go to the S2 Forum and order a complete set of the silicone hoses from one
of the group buys they have going on all the time? If you are planning on upping the
boost at any time stock hoses as we all well know aren't up to the task! I'm assuming
you are using either a 3B, RS2, or AAN throttle body, If you are using a RS2 IM a 3B (or
a RS2 or ADU) Throttle Body to pressure pipe (that's the one that runs along the valve
cover)hose will work?? Then just get an ADU or RS2 Pressure pipe and you're set it will
clear the valve cover will bolt right up! I've got a RS2 Pressure pipe I'd be more than
happy to loan you so you can make a clone of it if you want...then the stock RS2/S2/ADU
silicone hoses would bolt right up. Are you going to put a RS2 airbox in your coupe? I
was planning on going that route with one in my UrQ and have decided to go w/o an airbox
(or at least the RS2
one) in my UrQ, you're welcome to it and a RS2 IM if you're interested. Both are
spanking new!

I'm looking for information on sourcing or fabricating the intake portion for Engine
installed in '90 Coupe Quattro.  The engine is using RS2 turbo, RS2 intake Manifold and
IA exhaust manifold.  The Stock RS2 intercooler with integrated pipe in core support is
being used.

Probably I will need to fabricate the intake pipes, but can likely use stock 3B or
similar hose from MAF/Airbox - I have seen some nice turbo intake hoses from Neuspeed,
etc, so looking for tried and true alternative that facilitate 3" clearance from front
of turbo to core support vertical. 

The turbo outlet to intercooler is 2" and likely can use a 22 deg. + a 45 deg. Section
with overall length of about 12".  There is probably a stock hose that fit the Euro car.

The plumbing going from intercooler out is 2.3" to throttle 3" and could resemble the 3B
layout, but I might route around the firewall over to the passenger side fender well
then around to the intercooler.

Looking for BTDT suggestions, pictures, and flexible DIY tubing  for making convoluted
custom intake plumbing.

Exhaust solution will be addressed later - will likely be using an RS2 dual exhaust
downpipe similar to the 3B setup.
