re oil pressure gauge, mine does the same thing with the sr20, the gauges dont seem to be too accurate, but with ym car it has an extra oil cooler, so it needs more oil in the system than the dipstick indicates, so last oilchange i put more in it and the gauge seems to work better, never dopping to 0 like before, and sitting around 2 after warm up, i dont know, but i wouldnt mind an aftermarket gauge for oil pressure and water temp, cyas
