Hey guys, I have a 2.8l turbo bmw (details here http://www.dtmpower.net/forum/showth...hreadid=112097
Anyway, Proturbo makes beautiful manifolds. I have the Proturbo manifold adapter, and the welds are quality TIG welded. The full manifold that Miguel shows is very nice, and flows very well, in fact, probably better than the Turbocharging Dynamics one (which is cast, not tubular). Though, the downside to the proturbo one, is that it doesnt have a external wastegate port, and if you run a t4 turbo, you need a wastegate port for an external wastegate. I had one custom welded on to my manifold adapter.
