Interested. This is for N18, yes?
I have a 2013 countryman s w a blown turbo.
How wide is input?
I have been looking at ported headers

 

if you still have it, I'm still interested

 

get the tubular header off aliexpess !
Its an AMAZING combo with a k04... that header plus that warrior turbo will make awesome power with 0 lag..
IM running a k04 too and that header helped spool time and high end flow ALOT even v my jcw v2 manifold.

 

I really like that header.....

 

it REALLY helped the k04 spool too ! If someone buys this turbo I HIGHLY suggest getting the manifold I'm running with it. The power it makes vs the jcw turbo and square port jcw manifold isn't even comparable.
I'm making 26.5 psi on stock tune with my k04 , tubular manifold and supporting mods.
