[s-cars] Crossover pipe

[Michael Bess]

I believe I may have cracked my plastic crossover pipe.  Symptoms: I was
putting the boost 25+psi on my RS2's MRC set up and then a "pop" and
stumble.  Backed off and when tried again, boost came up to maybe 5 psi
before stumble and no higher boost possible.  I hear an air leak from what
appears to be the passenger side of the engine compartment.  Car idles well
and runs OK unless I get on the boost

 

Next day tried to pressure test the inlet tract via the MAF hose with a
pressurizer.  Couldn't locate the leak from the top and the pressurizer
couldn't get any pressure to hold; poked around and all the Semco hoses are
on their respective places.  Didn't have time to pull the lower tray and
check there yet.  I'll get to that tomorrow.

 

I remember seeing an aluminum replacement for the plastic crossover but
cannot locate who was selling it.  I also assume that an earlier S4
crossover which was aluminum would fit.  Any help on getting either one of
these.
