Thought i would put up a quick guide to fit a boost gauge, complete with a few pictures
First find a suitable hole in the firewall for sticking the tube through.
I found the place for me, was along side the (green) cable for the temperature controls:
I put a piece of wire in the thin tube, and pushed that through first, then the tube just followed behind.
I used a 'T' piece from a windscreen washer pipe, and used a spare bit of tube i had to attatch it to the 'MAP' sensor:
Here is the view from near the clutch pedal:
Now it is just simply a case of feeding the tube, to where ever you want to mount your gauge.
I have decided to mount the gauge, in the middle upper heater vent.
Excuse the gaffa tape, as this is temporary till i make a proper mould. I am hoping to be able to still use the passenger side vent, to give as much of a OE look as possible.
Picture of gauge in place:
Lit up for night time:
I got power from the ciggie lighter, to get the light working on the gauge.
I hope this guide works, for anybody else who wants to fit a boost gauge.
I now can confirm i am getting a peak 19psi, might crank it up slightly to get a nice round 20psi.
