If your actually going to be racing your car, consider a 5" autometer. I had one in my '92 CX/B18C1 hybrid and I loved it. The shift light was nice and when I drove with one hand on the wheel at 12 o'clock and one on the shifter, my arm completely blocks the OE tach and I can't see it. Mine was probably ricey but I loved that damn thing.
