Take back the keys!

? what u got

All mitsu's are going to be internal and cast into the hotside casting and will require the use of the factory 02 housing. You can run an 02 eliminator by welding the flapper on your hotside and going to an external; but obviouly at that point you won't require mitsu anything.

Look into an external setup only

well the turbo maifold and turbo im going to try to run at the end of this coming year will requir a external wastegate thats why im asking... the header has a down tube with an adapter for a seperate wasegate and a t3 turbo flang so ill be running a t3 turbo with my set up

Right, so just weld the flapper on the turbo's wastegate and mount your external and dump. What I was saying is you are setting it up for an external gate and there aren't any made by mistubishi is all.
