I've got a BD Super B 64mm turbo on and I was thinking about running my stock HX-35 for a twin setup. Good/Bad idea? Looking for knowledge!

Thanks!!

 

not a good pair
your secondary should be atleast 10mm bigger to be a good match

 

sell the special.

get either a S472, or a ht3b to pair with your hx35, then cross drill the divider in the hx35, maybe enlarge the wastegate and puck a bit, and put the pair together.

jacob from DAP can get you the plumbing for it...
