Have you looked at the Slowboy kit???

www.slowboyracing.com

Go to Evo -> Turbos -> Turbo Kits

 

ah thats why i didnt see it... i was lookin under just manifolds.

can you get the manifold/o2 housing seperate?

 

Both Slowboy and RRE are building kits around this manifold. It's cast stainless steel. The O2 housing is investment cast stainless steel, which gives a litle smoother finish. Slowboy posted a picture recently on here of a polished version, which is very pretty. They're in short supply because of delays in production, but are a very nice alternative to tubular headers if you prefer the longevity of a cast manifold. Looks somewhat similar to the legendary original HKS 4g63 T4 manifold that Shep, Brent Rau, and many others used for years to get into the 8s.
