thats a nice piece of work but im doing a 40mm internal gate. is anyone running 191's and DDP4's? how is the driveablilty and what turbo are you running?

 

How much is it worth? Can you use anybodies external wastegate?

I was just gonna get to T03 turbine inlet flanges and weld in some rectangle tubing. Cut in a hole for the new external wastegate. You could weld two thick turbine flanges together and put in hole(s) for the external.
