Hi Wylie,
There really isn't a difference in accuracy between the mechanical and electrical gauges. Both would work equally well in the 02 OEM mount so unless you really require an electrical boost gauge, I would just go with a mechanical one. If you have an 02 WRX, we have those gauges already in stock. No need for a group buy.

For the oil press and oil temp, the big disadvantage of mechanical gauges is that you have to bring the oil (via steel braided hoses) through the firewall of your car and to the gauge.
