I have original wagner evo, rs2 and original manifolds. Had them all on the table and when you look at runners then yes - ports are bigger and if you want to go grazy there is LOADS of material to port and grind to make it flow even better, but i didnt bother.1990 2.2 20VT Audi Coupe Quattro

Is the design by itself that much better to change the original one?'93 Audi 100 Avant - R.I.P

Right, I have an issue with the install.
It looks like the turbo and wastegate mount locations are different to the 3b manifold.
My downpipe does not mate up now.
The down pipe clashes with the subframe
Is it possible to get spacers fabricated to take up the gap?

Weird, I thought you had the two manifolds sitting next to each other and they measured up the same,
Did you change the turbo?
Is the motor sitting higher than before?

I was expecting maybe a small amount of 'adjusting' would be needed but but not this much.
Admittedly the downpipe was always close to the subframe when the 3b manifold was installed, probably because it was fitted to a different car before mine.
I will try and take some more measurements of manifold whilst its installed as I dont really want to take it off again unless I really have to.
