[s-cars] RS2 Turbo studs

[Tom Green]

Jared,

As I wrote earlier today, the studs for the manifold to downpipe and  
manifold to head are 8mm and the studs in/out of  the turbo are 10mm.   
None of these
fasteners are inexpensive.

The N 903 690 01 turbo outlet nuts (3) are $2.82 ea. The additional  
nut for the 15mm wrench is N 900 730 01 (1) at $3.96.  The inlet nuts  
046 145 749 (4) are $2.82 ea.  The manifold to head nuts for the 8mm  
studs N 902 002 01 at $1.94 ea.  You can't use ordinary lock nuts  
because they lock with nylon that will soon melt.  The exhaust  
manifold to head nuts were very cheap until these replacements came  
along that have a shoulder on the nut.  It supposedly had something to  
do with preventing manifold cracks.  Since they use those wide washers  
also, I don't see how.  You may have found on the manifold that you  
can't get the washers on the 4 shortened studs and still have enough  
stud to fasten the manifold.

Those were recent prices at genuinevwaudiparts.com.

If you have seen other turbo nuts  they may be suitable substitutes.
