If matching the OE gauges is the goal, then one route (albeit an expensive one) are the Greddy 52 mm gauges, which are very, very similar to the tach and speedo on an X. This will get you the standards (oil press, water temp, boost, plus EGT), but not AFR. I'm 99% sure that you can switch the bulbs so that they look like the OE gauges at night, as well as during the day. Then you only have to find a good AFR gauge.

The Autometer Autogages are also similar to OE Evo X gauges in appearence, but I can't in good conscience recommend them.

Stack also makes some nice 52 mm gauges that match our tach and speedo. The mechanicals are inexpensive; the stepper-motor versions are very sweet, but $200 each. But, at least they are white-lit, if you want a very good match.
