I want to get one more season out of my open housing T3 SC61 before I go big T4, but will be switching to a T4 twin scroll manifold, has anyone run that combo with an adapter plate? Obviously it's not ideal but will have to do. Any issues? Can the adapter be open plate or should it be a divided plate?

Thanks!

 

should be fine either way, plenty of people run divided housing with non divided manifolds and no problems

also a couple manifolds come with the t4 and t3 bolt patterns on the same flange

 

edit: solved!
