hi guys
i have a turbosmart dual stage boost controler (part number FG-GBCV-DS i think)i have a garett t3/t4 with an inlinepro manifold

this is what its supposta look like.


but my turbo dosne thvae that fitting called presure source so im stuck..... plzzz help

 

if your turbo has an external wastegate you shouldn't have to worry about it. correct me if i am wrong

 

The pressure source on the turbo isnt the only pressure source you can use. You can tee into a line that is leading directly off the intake manifold aswell. Do NOT use the line coming from the map sensor though, it has been know to be inaccurate. I belive you can tee into the pvc hose, someone correct me if im wrong. The point is though you can use any pressure source avaliable on your engine but its best to get it as close to the intake manfiold as possible.

 

So you don't have a vacuum souce coming from your turbo? Like SiEcO187 said, you can use the vacuum souce between your intake manifold and your fuel rail. If you are using that for your BOV and boost guage it may be too weak.

Depending on what car you have, you may have to tap into your brake master cylinder. (D16Z6s don't have a 2nd vac souce coming from the manifold)

First I would use the manifold/fuel rail VAC source and T into that for your boost controler. If it's too weak I would get one of the T kits that allow you to use your brake master cylinder. I know GE makes a manifold kit.

Can someone provide a 2nd VAC source other than the brake master cylinder for Z6 motors?

I think that even if he is using an external wastegate he will need a vacuum source so the WG knows when to open/close.

 

thanks for the help ...
yeah i was thinking bout a a vacumm line from the maifold ot split a line between my guage and controler? but like nota-eg said i dont want a week reading

the motor is a obd1 gsr with a skunk2 mani

 

Just get a GE vaccum manifold...it makes things much easier...and looks better after the install. It's only like 30 bucks...basically you tee it off of ur brake booster and then u have a vaccum source for up to 6 things (BOV, WG, FPR, Boost Cont., Map sensor, etc...)
