Can somebody please share a list of other turbo builders that will do this mod? Blouch has a 3 week + turnaround time right now and my turbos are already boxed up and ready to go.

 

I'd just send it to Blouch. Sure, there are plenty of other shops that are capable of the work, but I'm not sure of any that have done the volume that Blouch does. All of the tuners on this board seem to send their projects there. Just my 2 cents.
