Hi all, I pass this information:
I have found in Barcelona Spain, a company that offers Turbos IHI completely new RHB6, I purchased and installed one for my Fiat 124 Spider 2000 Turbo, and works great, also with respect to the original, this is the valve discharge adjustable.
Anyone interested can contact me;
