I'm putting together my turbo and I was just wondering if I've got the vac lines hooked up right. I've got an internal wastegate and I'm using a maplimiter (kind of like the afc hack) so there's no fmu. This is how I've got them running right now:

the bov is routed to the line that goes to the fpr.
the boost guage is also routed to the line that goes to the fpr.
and the wastegate is routed to the brake booster.

However, there is a vacuum outlet on the compressor side that I'm not sure about....where should that go?

Is this correct?

 

You could of used the turbo port for your wastegate instead of your fpr. Its acutally more accurate from the manifold than the turbo its self, but your going to have to block off that port on the turbo if your not using it

 

So instead of having the wastegate to the brakebooster, I should have it to the compressor of the turbo? Is this a benefit or a drawback?

Is it ok to have both the bov and the boost guage t'd into the fpr?

Thanks

 

WG plumbed to the manifold will result in higher boost- no loss through i/c or piping- not much though, mabey 1 lb. Just make sure you put it on the manifold side of the check valve!

Yep- that's how most do it, or you can drill & tap you manifold
