My question is if there is anyone who makes a turbo manifold upgrade. I'm not talking about HKS or Greddy b/c those are for an upgraded turbo w/ wastegate. I'm actually asking about a aftrmkt turbo manifold that utilizes the stock location with perhaps bigger piping. similar to a header on a n/a motor.

how does the flow on a normal manifold perform and what kind performance gains(if any) could be seen with a different manifold. once again keeping the stock mounting location so that a factory or aftermarket dp will bolt up to and/or a hybrid could acheive better flow with.

I've searched and havent found any usefull information. Some people have probed this question but an answer was never really given. i've alwas wondered this and was curious of what you turbo gurus thought.

i saw one for sale on ebay and YESSS i know that a Turbo Manifold from SS autochrome is not a good idea, but they have one for sale and although the craftmanship has been proven faulty in their turbo manifolds, the idea of a better flowing manifold intrigues me.

(NO I DO NOT PLAN ON BUYING A MANIFOLD FROM THEM SO DONT BOTHER WITH THE WARNINGS)

 

If you want a real upgrade from what your seeing, you'll need to go with an HKS divided manifold. The stock S5 one is pretty damn good with the stock turbo, as its divided.
If you go with any other manifold other than your stock one, you'll need to buy a new turbo charger, or at the very least, a turbine housing and use your stock compressor, if that will even work.
The flange on all the aftermarket manifolds will not fit the stock turbo.

 

ive never actually seen proof that the ss manifolds are crap?

 

I bought one off of ebay. The turbo flange was warped from to much heat when they were doing the welds, plus if you looked on the inside there was splatter welds everywhere. It looked like they tried to clean up the welds through gridning but it was stll poor quality shinny but bad quality.
