Just wondering on how hard (or easy) it is to install a boost gauge as I want to put one in my new car for the inevitable boosting upgrade...

All you need to do is find a vacuum/boost source on the intake manifold to tap into, run the vacuum hose through the firewall into the cabin, attach the boost gauge to the interior somewhere, hook up some power to it for the night illumination and you're set.

Cool, thanx guys. Anyone know of any pics of this for visual reference, doing the in cabin bit is no drama, its just the hooking of the vacuum hose to the right bit that i want to know..,..

NA plenum? mine is connected to the NA plenum where cruise control would usually attach. it is on the cabin side of the plenum at the top. i had a bung due to lack of cruise control.

Yer at the back of the plenum near the fire wall, there is connections, 1 is bunged up and the other runs to ur vaccum ball at the front of the car. Take the bung off, insert connection and run to gauge. If ur standing in front of the car, it's to the right of the brake booster, on the plenum.

Here's a pic of where I mounted mine, From where I sit it gives me a perfect view of the face and looks good in that spot as well. ...Also there is a grommet pretty much directly from where the T-piece is in the pic david85dc posted so the boost/vac line can go straight into the cabin instead of being twisted like that or having to make any new holes. Some original photos have not been recovered yet.

That last one. Where you do see the tubing coming out of it. My Blow-Off Valve is hooked up to it... wierd... Some original photos have not been recovered yet.

That's bloody useless to have a blow-off after the throttle butterfly, it's supposed to stop the turbo back-spinning when the throttle is snapped shut all of the sudden and the charged air goes back along the plenum/builds up too much

I think mine is too? that tube running at the top right hand side of the pic goes to the BOV, was like that when I bought the car, but it has to be connected to a vac line somewhere doesn't it?

...OR maybe I'm just seeing things and maybe it isn't but there is definitely a tube coming from the top of the BOV that runs to that side of the engine. Where is it supposed to go? I'm not down with the whole blow-off valve thing it was there when I bought the car. :S
