BTW, car is a '94/1.8 Assuming 2-5/8" diam. gauges will fit in the vent holes on the center dash?
Thanks in advance,

I am building my first Miata for the track. I used a mechanical gauges for oil pressure and an electric for water temperature on my last race car. Does anyone have suggestion for Miatas?
You will prob need to swap those for an NA car.

For water temp, either mechanical or electric will work. For mechanical you must put the sender in the upper radiator hose. Putting it in the heater hose will restrict coolant flow to the back of the head. Electric guage senders can be installed in either the radiator or heater hoses. Again, I sell an inline adapter for both types of guages

Just out of curiosity, what is the difference between the mechanical and electrical senders that causes the mechanical gauge senders to restrict flow? I guess I normally use electric gauges so I cannot picture how they would be different.A mechanical oil pressure guage requires an oil line be run into the cockpit. I have seen these leak, BIIIIIGGGGGGG mess inside the car and hot oil on drivers feet. I recomend electric guage. The hole in the block is BSPT, British standard pipe thread. The supplied adapters will not work properly. I do sell an oil relocation kit that has the proper fittings and works great for aftermarket guages.

I considered placing the gauges in the vent holes. Decided against it since it required me to divert my eyes away from looking forward a little too much. Instead mounted a gauge bracket on top of the dash next to the factory instrument cluster. It requires me to divert my eyes very little. Plus, at some point you may want a center net. If your cage has a reinforcing bar behind the dash that's a good place to attach the forward end of the net. Having an unused eyeball vent is a good means of access.

I have a halo seat and don't need a center net.

Thanks Dave, I just placed an order for the sender to be installed in heater hose!

Bingo, You're spot on here...after pondering the vent holes for the gauges, I just don't like the amount of time required to glance over and take in the data. Even on a straight where you have a few seconds, I don't like to take my eyes away from the track.
Thanks,
David

electric gauges and if i am not mistaken the gauge size is 2 1/8 for the vents
Thanks Brian,
David
