I have a few SR manifolds lying around my shop that I welded TIAL 38mm flanges to, this allows you to use an external wastegate and stock manifold/stock turbo location. This is seriously the kicker for making good power/torque on a small frame/bottom mount turbo. $125 each or $160 each ceramic coated black!
Stock SR manifold, bored a hole into it/welded a 38MM flange in place.

Also, if there are any of you with Pulsar GTi-R's or FWD SR20det motors, I can do this with your manifolds also. Just PM me. Doing one on an old HKS cast RB manifold this week. If you have a manifold and want EWG, I can do it.
