Stock t25 turbo/wastegate I don't know which vacuum line to tap in to for my wastegate and I wanna be sure before i do anything... I was thinking about trying to tap the line between the TB and the hotpipe on my fmic... let the flaming begin!

let me change the question, for you guys w/ sr20s or ca18s in... are you running the wastegate vacuum hose to the FMIC piping somewhere before the TB plate or somewhere after like the FPR hose?

Vacuum source on the hot pipe is fine for the wastegate actuator.

Basically, the closer to the turbo the better. It'll work post-TB but it won't work as well.

thanks, I ended up using the FPR line... I guess i need to retee somewhere closer... the tapping before the turbo in to the intake pipe wouldn't work would it?
