does anyone make an exhaust manifold that will fit a stock turbo?

 

re-amemiya. its about $800 and only works with an s5 turbo.

^Those are T4 manifolds, not for the stock turbo.

The second link i posted says direct replacement of stock manifold, They both come with t4 adapter flanges.

 

it's a lie.

 

So it wouldnt fit the stock turbo? how do you know its a lie?

 

because it has a t4 flange and is set up for an external wastegate.

^ those should work.

 

The adapters take it from T4 to T3

so it will only fit the stock turbo with the T4/T3 adapter.

But if used those china manfolds should be braced, especially with a heavy turbo.

 

the stock turbo is neither t3 or t4. they will not work.

 

Right. The T3 adapters are only there so you can use a T3/T4 turbo like some of the ebay "kits" use.

 

what he said ^

 

Waste of time and money IMO if you're sticking with the stock turbo.

 

I've seen a manifold or Two on forum that guys have just taken a T4 Flange and Drilled the Holes to accompany the S5 turbo.Not Good in My opinion.
But another Idea is to take a Grinder and Whack the S5 turbo flange off the cast manifold and weld it on a Homemade Manifold.
Barnett,I have a Good Homemade Manifold..Cheap..uses a T4 on it..and a 38 MM flange for wastegate.if interested PM me.

 

I dont think its worth the trouble or money for a small gain.
