Ok I ordered the Zex N20 kit and decided to do it myself. I got everything down except for one part. From the management unit i am supposed to connect a hose to a "unused vacuum fitting coming off the intake manifold plenum". Are there unused fittings somewhere? Where can I look? Does the upper intake have to come off? What Should I do?

Thanks
Henry

There should be a vacuum T at the back of the upper intake manifold, and I beleive only 2 are used, but there are 3 fittings. I'm pretty sure this is what they are talking about, it would be easier to take off the upper intake, but if you can get in there, the fittings run along the driver side fuel rail underneath the upper intake plenum.

hey how's the zex kit working out.... im thinking of getting one too. how much did it cost ya, and what mods did you do to the car?
