Going with a 6266 turbo. Was looking at some recommendations on exhaust manifolds with a t3 flange. Was looking into trying out steed speed. Would like to stick with a twin scroll setup.

 

Is the 6266 even available in a t3 divided housing? I can only find it in T4 divided. Steed speed makes nice part but I'm not the biggest fans of their designs. If you really want twin scroll just go T4 and your options open up a little bit. Full race makes a very nice T4 twin scroll for example

T4 is gonna be very laggy
why dont you just get a whole turbo kit AGP makes a great turbo kit for an awesome price

 

I agree T4 would be a little more laggy, but a properly sized T4 twin scroll setup wouldn't sacrifice that much if any to a comparable flowing AR in a T3 setup. I would however stick with your suggestion of just getting the AGP kit if OP doesn't already have everything else to support that turbo
