[Es2] MAF - turbo hose for tight clearance RS2 turbo in Coupe Quattro.

[Steve Eiche]

Matt,
Yes, that looks like a 200 20V hose.  The 3B S2 hose has a bend in it 
toward the fender between the turbo and MAF and is a bit longer.  The 
ABY (and RS2 I assume) hose is flat on the front and has both the WGFV 
and BPV on the right side.

I found that the ability to reach full boost is very sensitive to this plumbing.  You can't just plug the valve into the front of the hose like it is supposed to, as it won't fit.  I ended up using a short length of 1/4 copper pipe.  This provided less restriction and I'm able to reach full 20psi boost with a stock spring and about 5-6 turns on the cap screw.
