Does anyone have the facilities to make me a restrictor ring for my na-t please? I want this size (shown below), made out of around 1/16th" thick steel with a 1.75" large hole in the middle. The downpipe and 2nd decat are both 3" pipes.

Can't you just spec the correct size of wastegate instead?

 

I could but that would mean a new wastgate as i cant get a spring for mine. I would then need a new flange welding to the manifold too and i just dont have the time or money at the moment. I am saving for a nice wastegate but this is the best method in the meantime to reign in the boost.
