Wastegate Options with PTE Cut housing

[talonz27]

so i bought a SBR G50 with internal gate and was thinking about going with an external gate. i was going to do the wastegate off the o2 but i hear you cant do that with a cut housing. what other options do i have for running an external wastegate. or am i SOL and will i have to just do it off the manifold?

Well if you cant do it off the o2 housing then that leaves the manifold.
Theres nothing wrong with that. Thats what Im doing
