Help - 200TQ big boost leak on trip

[Geraint Lloyd]

Kurt

I too had a problem with the turbo to intercooler hose
on an mc2
mine had (turbo to intercooler) : rubber J hose->
plastic foam filled 
'silencer'-> rubber bellows

the bellows had split and is apparently NLA.
these people:
http://nitra.audidealer.com/rusnak-pasadena/en_US/
had a bellows in stock (NOS). I didn't buy it.
apparently there was a rubber hose available to go
from the turbo to the 
intercooler in one go i.e. no silencer.
I was quoted $350 canadian for this hose, which is
apparently still 
available.
350 bucks, well b at llocks to that!

in the end i fixed it with a bit of silicone hydraulic
hose and a steel 
hydraulic hose connector from my local hydraulic
equipment store for $20 CAD
i actually spent $50 canadian, but most of that went
on stainless hose 
clamps.
in for a penny......

the J tube was 1/4 of an inch smaller in diameter than
the intercooler 
inlet hence the steel connector (bigger on one end
than the other 
by....1/4"! wahey)
diameters are 2.25 and 2.5 respectively i think, but,
by now you should 
have the bits in font of you to measure properly.

I took a pic and will send it when I get home this
evening. 
unfortunately, i haven't got it with me

anyone else interested in the pic, please email me
this arvo (monday)and 
i will CC you.
sorry, but i haven't got an ftp site to upload it to
(yet)

regards
geraint
