im getting a cheapy boost gauge through the post in a couple of days so can anyone give me details of where to route it to on a my93 WRX.

Does it go to the dump valve? or is there somewhere better?

Thanks

The hose should go to the inlet manifold, there should be a rubber blanking plug in the middle slightly to the right, next to where the vacuum hose for the dumpvalve is.

When you say dump valve I take it you mean you are T'ing off the small 1/4" hose? In that case yes that will work too. As will T'ing off the hose that leads to the actuator on the turbo - where the current T piece is, but the latter is less ideal as you may get you gauge vibrating due to the purge soloniod opening and closing.

As for routing it There should be a grommet right by the clutch master cylinder. It's an **** to get at, but it's the shortest route from the drivers side. If your passing it through on the passenger side, just make a hole in the grommet used for the A/C hoses (big oval shaped one).
