i heard that it was possible to block off the internal wastegate hole and just use a external unit. i got a manifold with a port for a wastegate but my turbo has internal setup. anyonw got any ideas how i would be able to do that. thanks

 

Various ways. I would just remove the internal wastegate, and weld the flapper door shut. Either that, or get a flange made to cover it up.

 

what turbo is this?
