okay i know wat, Im gonna put my BOV and boost gauge to the fuel pressure regulator. and wastegate to... i think to that vacuum source on the back of the manifold where right now i have the boost gauge set.
Does this sound good? Cmon i need help im firing up my car tomorrow.

sorry to post so late, i just came across it again. the charcoal canister is behind the intake manifold, right where the "M" in the word vacuum lines you wrote on the pic is. the one under the throttle body is for coolant. come to think of it. don't T off the pcv valve ok. do it off the charcoal canister. it's the other intake manifold outlet that's next to the blue line you drew, the closet one to the back of the intake manifold by the firewall. i hooked mine upto that and now it's rock steady boost, no drops at all. just 1 1/2 more psi in 4th and 5th gear. i'm lovin it. :P

why would u put a MBC on the bottom nipple.

dont all boost controller hook to the top nipple, because they bleed pressure into the top port putting more pressure on the TOP of the diaphragm making it harder to open..

or am i wrong?

Laosta

no your right, i drew it wrong,

then why doe projekteg have all those pictures, they are all wrong.

projekteg

for an mbc, you hook it up to the side (bottom) nipple and let the top vent to atmosphere, you only use the top and side with an ebc.

i got it, never mind, i found that i had a spot on my turbo housing that has a great vacuum source for the wastegate. everything is great! Car is running, spooling a lil late but pulls like a ***** @ around 4k.

thanks, learn something new every day.

if you connect the wastegate to a vacuum/boost source from the intake manifold, the turbo will spool much faster. i experienced this in my own set up.

i got a t3/to4e turbo and right now im at full boost at around 4-5k. low boost is about at 2800 and up. you say that i can spool up faster if i change the wastgate vacuum source? b/c right now the wastgate is running off the turbo housing. i suggest i plug it up and run off that charcoal somethin line? do i just run just the wastegate line to the charcoal line? or do i also add the BOV line to it too? Wat about the Boost gauge? where did you hook it up at?
