ok so as many of you know my car has been down for the count for a while. in my possession i have 2 16g turbos fully functioning, no shaft play, etc, i also have 2 9b turbos, both with fresh cartrige rebuilds, but one has a torn up cold side turbine and housing. (so its bassically worthless) i have a way of getting the 16g to fit the front manifold (the oem mani's are td04, 16g =td05) so thats not a problem, however, the rear turbo manifold is made of cast iron, so it cant be welded. looking at it there is a ton, and i mean a ton of custom work that needs to be done to make the 16g fit in the rear. so what im thinking is running the oem 9b in the rear ( thats the one that works perfectly) and running the 16g in front. just seeing what everyone else thinks.

I think you'de be mad to do that. I'm not a fan of running sequential turbo's on our motor. I know it has been done. I believe 9b/13g combo I believe. And he can do that as the turbo's aren't hugely different. Your talking about combo-ing a 9b and a 350+HP turbo? I think that would be nuts. Perhaps PM Struggly at 3si. He knoes his stuff.
