this is on a stock SR with the stock turbo

is it ok to run the vacuum line for the wastgate to one of the vacuum ports in the intake manifold?

if i run it to the mani can i T my BOV off that line also?

i searched and it seems other people are running it to the hotpipe but mine doesnt have a fitting and i have to get the car up and running asap, and ive seen mixed responses on where to run the bov line too, i just want to be sure so i dont f*** something up

Yes you can do it, its just recommened that you run it from the hotpipe so that the wastegate gets its OWN vacuum source. You can also just have a bung welded onto your hot pipe and thread a barb hose in there, or just tap in a barb hose into your hotpipe, thats what I did. Works awsome.

just get a brass 1/8(?) inch bung and use a drill bit smaller then the bung and drill it as close to the turbo as posiblle perferably, for better response. then tap it. and test to see if you can screw the bung in and when you can unscrew it and use jb weld on it and screw it back in. did it on my old hot pipe and on my new one.
