Has anyone ever used one of these one of their setups? Also if anyone knows what there set at from the factory?

 

Set at 1 bar...14.7 psi
Seen a few setups with them...use another wastegate spring

 

I jus took a quick glance at it and didn't notice a dump tube back to the exhaust or anywhere or maybe I just didn't notice it? Also what is the banjo fitting for?

 

The opening on the side goes back into the exhaust and the one underneath goes to the manifold, but I see some iron crap on the side that goes to the manifold. The banjofitting connects to a vacume/boost soarce.
The upper nipple you leave open or can use for a EBC.

 

So could you just cut the spring in there and lower the psi?

 

I could get one for 10 bucks cause if the guy at the front desk at the junkyard doesn't know what it is then it's ten bucks! Hell it can't more then 50 bucks cause any turbos there are only 50 smackers.

 

get it...you can get springs on ebay really cheap

 

Only thing is that there a pain in the *** to get off in the junkyard. But hell for 10 bucks what can I lose?

 

The spring size depends on the year. The shape is the same for all this type Audi wastegate:

81-91: urquattro 10VT = 1 bar
87-91: urquattro 20VT = 0.75 bar
91-92: s2,s4 20VT = 0.75 bar
81-86: 200T or 5T 10VT = 1 bar
87-91: 200T or 100 Cs 10VT = 0.8 bar
88-91: 200 20VT = 0.75 bar
93-96: s2,s4,s6 20VT = 1 bar
94-95: Rs2 20VT = 1.37 bar

1 bar = 14.7PSi

Many people uses this Audi wastegate for custom setups here (reliable ones), but they are very huuuuge (at least double size of a Tial 35mm) and need lot of space in car.

 

Yeah I noticed that they were a little on the bigger size, but I can figure something out. Thanks for the WG PSI setting of the years! Cool thing is that it already comes with a dump pipe on them!
