Wastegate Problem ???????

[72nismo]

I dont get it but I tried installing an external wastegate with my internal wastegate set up.So I disconnected the internal wastegate.Then I connected the EW to MBC and I ran the car but i got no boost.So then I voided the MBC and connected straight to EW and Turbo compressor and it still didn't boost. Anybody know what im doing wrong.:ugh:
FYI. I haven't connected the exhaust part of EW to my exhaust.I was told I didn't have to and that it would just be really loud.

Your internal wastegate flapper is opening from exaust flow and not allowing you to spin your turbine to make boost. Take the turbine housing off and weld the flapper shut. This is what i had to do to get my 2871r to work with an external gate. Good luck!
