I have an external wastegate for my turbo setup and i have a question about the two holes on the WG. i have to hook a vacuum source to the side one correct? what bout da top? i saw some setups where they left it, not even plugged up.
Wat should i do, plug it up? or connect another vacuum line to it?

shortyz

hook a straight vacuum source to side nipple leave top nipple open unless you are going to run a boost controller.

i am gonna run a manual boost contrroller, so what do i do? right now my wastgate is setup this way.

is this good, im running a vacuum line off the side of the WG and the top open. leave da top?


also wheres all the good vacuum sources at?

anyone?

i'd T it off the hose that goes to the middle of your block next to the BOV/FPR vacuum line, the PCV valves i think it is. so the wastegate has it's own boost/vacuum source and not a shared one as it would if you would've T'd off the BOV. about the boost controler, i had a bad experience for me anyways building one, i ended up buying a turbo xs mbc off ebay and it works awsome.

definately don't T it off the FPR. i wouldn't even T the BOV off the FPR since i see you have the FMU Td' off the FPR already. here's a pic of how i did it off a big vacume source on the manifold, i was gonna do it off the PCV hose which is that larger hose you have going into the top middle of your valve cover on the intake manifold side. that vacuum source is large enough to where you can add a TT one of those Ts' that has 2 outlets so you can T 2 things off 1 source. here's the pic

i didn't T off the PCV valve after all. i T'd off the charcoal fuel/emission filter cause it was gonna be much easier then the PCV. i did it with a plastic T editplatic T painted flat black) instead of the bulky brass homedepot T <-what was i thinking .
close up:
further away so you could see where i Td' off.

hardly no boost spikes at all with an internal w/g. only a 1 psi boost spike on 2nd & 3rd gear. now that the waste gate isn't feeding off the fuel pressure regulator, and the BOV vacuum source, the BOV doesn't flutter on low psi (5-7psi) and the BOV sounds louder too. but the main purpose as why i did this is to avaoid buying a $40. vacuum manifold and to end of reduce the almost 3psi in boost spikes i was getting. i already drove the car for a while and it worked out good.

okay this is my actual engine bay, i didnt get to take a pic of my engine wit the turbo in yet. this is the way my vacuum lines are set. I dont have a FMU.

blue: vacuum lines
pink: Blow off valve
Green: wastegate

sorry bout da bad artwrk.

so i should tap the wastegate vacuum line into the charcoal fuel/emission filter line the one that has the red writing on it. mine is on the throttle body right?
