wow thats a big jump - probably more than cams....

So the 82mm is 82mm internal? vs the 80mm which is 78mm internal?

Anyone ever measure the vacuum at the TB entrance?

This is correct

The stock 74mm y-pipe will not fit the 82mm tb. The od of the stock y-pipe is about the same as the od of the 82mm tb.

Guys I know this has been covered a couple of times. I look i different threads and find different part numbers from different people on this. I am doing a 82mm Audi TB install .. here are the part numbers I have seen needed for the install:

80mm Plenum
A113-140-09-12

Gaskets
A273-141-06-80 (Throttle Body)
A113-141-07-80 (Plenum to SC)
A113-098-00-80 (Right Intake)
A113-098-01-80 (Left Intake)
A113 141 09 80 X2 (super charger to head)


I have seen two different part numbers for the y-pipe kit

A113 090 01 29
A113 090 03 29

I think one is with and one is without the pipes. Can someone help me confirm which one I should order?

Thanks to all the helpful threads! However, some info changes from thread to thread. Did I miss anything from the list?

Thanks!

+1 did same thing I did worked great although had minor leaks right where the throttle body meets the y pipe

So is the best method for an air-tight fit going with these parts? The 80mm y-pipe and a couple O-Rings?
