So the choices are using the 2nd gen gte TB w/ The 3sge manifold and will have to bolck that passage off or use the 3sge TB w/ the 3sge manifold. The inlet inside diameter of the 3sge manifold is the same diameter of the 2nd gen 3sgte ,anifold, so i assume that the 3sge TB is the same inner diameter as the gte TB. So i dont think that there will b any issues with flow here. I am going to order the 3sge TB so i will let you know when i get it and how it fits on a 185. Not sure if that helps at all. Just some things that i was curious about
