All of my gauges are 52mm White Faced Gauges. Currrently I have Fuel Pessure (which reads in BAR, similar to boost because its pressure), EGT (which reads in Celius, s 0-900 degrees), and Boost, but its not hooked up yet, but it will also read in BAR. All of these gauges match the stock gauge color beatifully, which of course is green. But, these gauges have a green needle, not red like your looking for. I *think that Apexi makes a black faced gauge with a red needle, if I remember correctly.
