Yes, the clock would be ideal... Quite a bit too much work involved for me though.

I don't have much free time, so the idea of spending half a day pulling the dash out to fit a boost gauge isn't ideal. If rather fit one in a different position and spend the rest of the day driving.Comment

FYI: As soon as you change the MAP sensor in the ECU from 250 kPa to 300 kPa, the calibration of the in-dash OE digital "boost" gauge (actually more correctly an "Absolute Pressure in the intake manifold" gauge) is fubar'd. Useless other than a vague sense that you are making boost (over 1.01 kPa atmospheric absolute pressure).
I like my boost gauge (relative boost, with vacuum) location (see below). If replacing the clock with a boost gauge was easy, many many UrS owners would have done this ages ago. Truth is I know of one or two that have done it. Problem is those three gauges (including the clock) are NOT indiviual gauges. They are three faceplates that attach to a single printed circuit board. Replacing anyone of them with anything, e.g. clock for boost gauge, requires major circuit board surgery and wiring.

Had to burst my bubble didn't you?
But on a serious note, thanks for the input. I have 2 speedos so I'll have a look into it and see what's what
Another way is to replace all 3 gauges with same style ones

182k good effort! A few more miles than mine.
Are digital or analogue gauges best?
Hoping to buy one this weekend in some shape or form.Comment

It's a good idea. Just very likely beyond your skill level. In almost 17 years of UrS ownership and UrS forums, I have only seen 2 boost gauges installed where the clock was. Nobody ever shared how exactly then did it either. (Nice, thanks guys).
To do it, you'd have to a) figure everything out about Item 16, printed circuit board and b) the re-engineer connections/wiring to individual gauges. Maybe you could do it. But even then, the location is NOT optimal for checking while driving. A-pillar or steering column pod would be better. I mocked up something for the top of the dash but didn't get any support/demand so I dropped it. (I am more than happy with my A-pillar gauge pod)(See below)

It's definitely beyond my skill What I meant was, I could replace all 3 gauges with aftermarket ones. For instance:

Not these ones as they look horrible, but you get the idea.

And to fit it in pillars or vent won't take less IMHO. 
there should be enough info on here to make it easier.
