Returning to stock...where to route vacuum line for wastegate

[thach]

I bought my car with an ebay turbo and external wastegate. I am replacing it with a stock T25. My question is where should I route the vacuum line that was oirginally ran to the external wastegate?

Car has a boost gauge, greddy type s bov, no boost controller, emissions all there.

Run a line from the WG actuator to one of the ports on the intake manifold.

On a T-25, the compressor housing has a nipple on it. For stock performance and without setting up the boost control solenoid, all you need to do is connect the wastegate to the compressor housing as seen on the left here:

If you wish to set up the boost control solenoid (true stock form), check the original vacuum diagram: http://www.dsmtuners.com/forums/articles-miscellaneous/198327-taboo-speed-shop-vacuum-diagram-removal-1g-2g.html.

I actually have the WGA ran to the compressor housing.

When i received the car, the external wastegate the p/o had was routed to a nipple on the intake manifold, and t'd off to the boost gauge. Where should I run that line now? I want to keep the gauge functional.

I'll get a pic tomorrow if it helps

The boost gauge is commonly run off the small nipple for the fuel pressure regulator on the driver side of the manifold, seen quite plainly here: http://www.dsmtuners.com/forums/bolt-tech/358381-intake-manifold-help.html#post152088065.

A pic would do nicely to show us what the previous owner did to your car.

Here's a picture I took when I first got the car. The line i'm speaking of is highlighted. And my mistake, it isn't routed to the boost gauge! Looks like it's t'd off to the bov. Sorry

Right. Eliminate the "T", run the BOV straight to that nipple on the intake manifold, and you are set.

Doh! I just read a few threads about how to route the bov...so this should've been obvious.

Thanks a lot man
