GN1downpipe with 46mm external gate

[trixdout]

Question is though, what aftermarket wastegate will fit the gn1 3" external dp? Which will fit that 4 bolt pattern? Or do you have to get any wastegate of the size you want and cut off the 4 bolt mounts and weld in mounts to match the wastegate?

nothing fits those flanges , cut it off and weld on a precision PW46 , it uses vband connections
while your at it.. cut the pipe from the gate close to the downpipe (about an inch or so) , with a die grinder reach in and clearance the inside where that pipe joins the downpipe
and when you go to weld it back install a short flex coupler

How do u get the rvt gasket maker stuff on the flange where it goes when the flange is only about a 1/2 " off of the turbo housing with no room to play?? Sigh
