I'm planning to = order the VDO=20 Cockpit Black Gauges (egauges.com). Here's what I have in=20 mind...
 
310-012 oil temp -=20 300f
310-039 water temp -=20 250f
350-065 oil pres -=20 100psi
150-052 turbo boost=20 - 30psi
310-901 cyl temp -=20 600f
310-953 EGT -=20 1600f
310-041 volts -=20 16v
 
Does = this match=20 you're list?
 
What senders=20 (thread size or model numbers) did you get with each gauge and = where did=20 you hook them up? 
 
Hi John,
 
I don't have = the model=20 numbers written down, but I remember the ranges.  Your = list looks=20 fine, with the following comments. =20
 
- I don't currently have a cyl = temp, EGT,=20 or voltmeter (will come up with something temporary though), so I can't = comment=20 on those particular gauges. 
 
- I originally bought all my = senders in=20 1/8" NPT size, and planned to use adapters.  This turned out to be = a bad=20 idea, so get the proper threads.  Here are the sizes for the ones I = used:
 

Water temp in water pump housing- M12 X 1.5

Oil temp (in pan)- M16 X 1.5

Oil pressure- M10 X = 1.0

 
- You'll notice that = they don't sell=20 a 250 degree water temp sender in the M12 x 1.5 thread, but they do = sell=20 one in a 300 degree range.  I know this very well, because bought = the 250=20 gauge and sender, and had to turn around and replace it with the 300 = degree=20 combo.  Of course that means it will say "oil" on the front, so = you'll have=20 to put a new label over = it.  
 
- I got the 150 psi = oil pressure=20 gauge, but your 100 degree range is a better=20 choice.
 
- Finally, I didn't order = the boost=20 gauge in the cockpit black series, because I didn't like the ranges that = were=20 available.  I personally think the vacuum/boost range is more=20 useful than the ones that are strictly boost.  You'll = spend a=20 significant amount of time on the vacuum side of the gauge, and = will be=20 able to see the needle approaching boost.  I mounted my gauge=20 permanently, front and center on the glare shield, because it makes a = better=20 quick reference for the amount of work that the turbo is = doing.  It=20 also tells a different story than MAP.  The boost gauge is a=20 differential device, so you will see when the turbo is producing boost = over=20 ambient pressure.  You could figure this out with a static absolute = pressure sensor too, but the boost gauge gives it to you directly.  = The cockpit black=20 series goes from 30 vacuum, to 25 pressure.  Since I can't = imagine=20 using anything over about 8 psi of boost over ambient, I wanted that = range to be=20 expanded more.  I chose the vision 1 series (150-361) = since it=20 went from 30 vacuum, to 15 pressure.  I would have preferred = that it=20 have a black bezel, but the range was more important to me.  = It=20 doesn't even matter that it doesn't match the other gauges, since this = one=20 stays, and the others are=20 temporary.
