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

[Matt twentyV]

Ben- first I know I still owe you some pictures I promised to take of my setup.  Maybe tonight if I can remember!

One option might be an RS2 intake.  Dean Treadway's ES-2 has a crate RS-2 motor, and I presume that included a stock intake.  It fits behind the the vertical mount, I've seen it myself.  It has the same problem I do with the N75 mount but again, I've solved that one.
