oil preasure
I know its stupid but what is that gage is for?
It stays like 2 bars over half.
My lat car didnt have it
Whats the difference when its on high or low?

It is essentially the same thing as a dummy light. It either indicates pressure (just past the middle), or no pressure. I don't recall the exact psi that triggers it, but I believe it was down in the 5-7psi range.

I had it at the middle with 4 quarts of half dirty and half clean oil on a dirty filter.
I drained and put on Purelator PureOne filter and 5 quarts of Castrol GTX 5w30 oil and it shot up to 2 bars over the half.
I suppose two bars over the half is a good place for it to be.

Its a dummy gauge, no matter what you do, it goes a little bit beyond the middle area. I have NO idea what Mazda is thinking, I mean a *functional* oil press sensor dont cost that much ... they stop doing it since I think 03 or 04 on Miata, not 100% sure.
That gauge actually serves 1 purpose, if it stays at L even when your engine is on, that means your Engine is going bye bye. Thats about it I guess.

Jason is correct full set separate guages.
As far as modifying the actual Mazda guage to read, it can't be done. The first Miata's had a working gauge that was changed to a "dummy" gauge mid 90's and there was a way to get it working by installing an actual sensor and then "calibrating" the gauge face. But the RX-8 guage doesn't work the same way so a pressure sensor won't work with it.

You guys are correct; the Mazda gauge is in fact a 'dummy' gauge. (very much like the temperature gaguge. 
)
If you wanted real time oil pressure, I'd go with the racing beat gauge pod.

the temperature is in fact a *working* gauge, but the problem is that, by the time it moves beyond the usual *middle spot*, your engine is already on her way to rotary heaven. It moves @ like what? after 220f I think.
Thats why I installed bunch of *real* defi gauges.

hence why I said it was "Much" like the oil pressure. (note: did not say it was exactly like the Oil gauge 
)
Yup, here's what I did when I got sick of the oem gauges.

Do you have to drill the pan to install those or do they just fit in to replace the OEM sensor? Won't that throw off the ECU if the OEM sensor doens't send signals to ECU?

for oil temp and press, all you need is the oil filter adapter. Like RB or Annversity or Greddy. I had Greddy before but for some reason it leaks, I probably used the wrong bolt on it. ahh who cares, I got the Anniversity one and Im happy. no leak whatsoever.
After the adapter you'll need to buy 2 sensor set of course.
For water, same thing , u need a water adapter. I think I post mine up a while ago. you can look at it.

Yeah, they're almost a pefect match to the oem display. (just slightly brighter, which is good)
I'll most likely be putting up a thread / DIY on those this weekend. (after I take a few more pics)

Basically they don't want to have to explain to customers how to understand a real oil pressure gauge.
The real day-to-day value of an oil pressure gauge is that it gives you a good indication of when the engine is fully warmed up. All the more important on a rotary. It's a shame.

Sorry to say I will not buy anything thats made by Ford ... when my father was shopping for a new car, I push him to get CX-7, he wants the CX-9. I was like if you want failure, go ahead and get CX-9. Damn ford
