At the risk of starting an un-necessary argument about which gauges are best, wouldn't it be more useful to put in a gauge of something that could potentially harm the engine?
Air/Fuel ratio gauge, EGT gauge maybe?
The idea being to monitor key systems.
Of course your oil temp is important, but your 9000 Aero has an oil cooler which should take care of that with reasonable reliability even if you tamper with your power output a little.
AF ratio and EGT are both things that are essential to monitor. Unless you're absoluely sure that you won't ever take the hands on approach to modifying it might be best to put one of them in now while you can. You'll want to fit them later, so why not do it now?
If the gauge will be purely decorative I'd stil go for A/F ratio or EGT as these are both highly variable parameters and lots of fun for your passengers to watch, just like the boost gauge.
The A/F ratios often even have flashing moving lights. Very neat looking. Perhaps not the cheapest, but more important than oil temp probably, and certainly good for the "bling bling" if you know what I mean.
Oh and keep on
