i need to know where the vacuum pipe goes on the engine have a look at the pics my car is an my97 impreza turbo

 

On mine, which is a '98 car, the boost gauge pipe is fitted to the front unused nipple (ooerr missus) on the n/s of the front of the induction manifold, in front of where the blue pipe is fitted on yours. you can see the one I used, it has a rubber sleeve over it.

Cheers mate what is yours reading on your boost gauge mine is 13 psi on full boost and then levels about 12 psi

 

Ho...........well..........mine is in bar, and DID read about 1.0-1.1 bar, but after a LINK ECU, and remap, it now reads 1.3 bar, with about 1.4-.1.5 bar as max.

1 Bar being around 14 psi, IIRC.
