Earl Posted November 16, 2010 Report Share Posted November 16, 2010 get a hold of S.M.B=D he's the only guy that makes a custom header and it is to die for=) it's $480 shipped i believe=~) and the turbo flange on our cars is one of a kind...so you can get a 14g or 16g, and put the internals into the 12a=) it may require a little porting inside for the wheels to fit=) i've seen a 20g i believe in a 12a housing but i think it cracked from being so thing...otherwise you can get a t3 treadstone cast manifold and use any array of t3 turbos=) just don't over boost because you'll be out of rod bearings and a head=~) hope this helped Link to comment Share on other sites More sharing options...
Komeuppance Posted November 16, 2010 Report Share Posted November 16, 2010 Upgrade your fuel system to handle the extra boost first, unless you like melting pistons and rebuilding your engine. -Robert Link to comment Share on other sites More sharing options...
NotStock88 Posted November 16, 2010 Report Share Posted November 16, 2010 Maybe I am missing something here but is there actually something here for sale or are you just asking questions on how to upgrade your exhaust manifold? You do not need a header. I suggest getting a new OEM stock exhaust manifold from DAD, have him stress relieve it and port it. You will make all kinds of power and not suffer from cracked runners.
