I have a manifold that has flanges meant for the 50mm Synapse waste gates. However I want to run Tial gates. I know the 50mm Synapse will fit onto the MVR vband flange, but would it work vice versa? I heard something about the Synapse flange lacking a valve seat is what stops the MVR from fitting-or would I be able to have the valve seat added to the flange? I've only used the 2 bolt style til this day so slightly confused on the configuration.
Anyhow, does anyone know?
Thanks for any input. I did email Tial USA about this but no reply as of yet.

 

As I recall no the flanges are different. The Synapse is a flat flange and the Tial wastegate has an inner ring that wont fit with it.

 

Hah. That sucks. The flanges are the same size though so I guess I'll just have to get this one cut off and reflanged..
Thanks Jason.

 

Jason is correct. They are different. I've tried it.

 

Damn. Would you see any problems if I cut off the old flange and welded a 38mm vband flange on? As in the wastegate runner would become smaller as it approaches the wastegate because of the smaller vband flange.

 

A single 38mm gate is too small for an fd. You running duals?

 

Yeah it's dual wastegate runners.
Its flanged for 50mm synapse. Might wanna reduce it to 38mm mvs.

 

Why not just run the 2 synapse gates? I can get those as well.

 

Not a fan of the synapse gates really. Shoot me your price for them, it's always something I could consider.
