correct,
but you have it or you dont. and oil temp at idle will give you a big clue if you have a oil pressure issue..
have not read a lot of issues with rx8s loosing oil pressure..
hey just my opinion, i could be wrong.
but i did buy a wide afr, an oil temp gauge, and a vac / boost gauge.
the rest will be done by scanalizer.. or some other obd 2 device.
as i am not fi. the fuel pressure question is a good one..

I've got a turbo setup. Initially only had a Boost Gauge as that is a very basic requirement and am going to be getting more gauges. I have an AFR gauge ready to put in and spots for 2 additional gauges. So what should I fill those 2 spots with?
I was thinking important ones might be water temp, oil temp, and oil pressure. So which 2 are the best to have? And if there is another gauge I don't know about that is important too, do tell. Personally, I was thinking the 2 oil gauges, but I'd like to hear some opinions.

If you wish to do any kind of wild experimentation, two EGT probes with atleast 5V logging capabilities is necessary. At the least in this circumstance, a single w/ cockpit output will work. Probes to be located in the exhaust manifold and not the downpipe.
Btw, what kind of AFR gauge are you using and which sensor does it come with? If it has a Bosche sensor or is the AEM unit, sell it and get yourself something with an NTK 5V sensor and perhaps the NGK AFX or PowerDex units (provided you purchase the one w/ the NTK sensor already equipped).
Don't be misled into buying these Bosche 5V wideband sensors, folks. They're trash.

Thanks for the feedback BDC. Unfortunately I already bought the AEM AFR, so I guess I'll see how that works out and swap it out if need be.

...maybe also a gauge that says '# of miles until blown apex seal'?
...it starts counting down from, say 50,000 miles, and goes down on a 1:1 ratio if you have a perfect tune. Anything less and it counts down at 10:1 100:1 etc. or just pegs low when you pop yer engine.

hey man - yeah don't worry so much about EGT, especially if you don't have a cat. If your AFR's are in the right place, you shouldnt have to worry about running too hot.
As mentioned above, oil pressure is important for monitoring the turbo setup, but I don't know too much about that. What I do know is that it's COLD AS ***** in NY in the winter, and you want to make sure that your oil is up to temp before you do any really hard driving. In this winter this can take a surprisingly long time (20-30 minutes!) So I'd feel the need to monitor that if possible, just for peace of mind.
Try getting gauges that give info that you can't get from an OBDII reader (oil pressure, oil temp, WBO2) Then get some reader device (scanguage and there's a few other good ones) to keep an eye on all the others.)
Where are you mounting this stuff? A-pillar always seemed a little rice to me.....racing beat makes a nice ashtray pod, and there is a center dashboard kit.
Good luck there....

Using the Lotek pod which mounts in the center panel above the radio. Didn't want to worry about the air bags in the pillar, and ash tray is out of the question, I don't want to have to glance down there for readouts. Nice location, but the quality is lacking in my opinion. Will definitely repaint the whole panel someday.

I'd get a really good AFR (There was a shootout on these and the AEM's / Innovative Motorsports were the best, Zentronix was the worst).
Oil pressure + Oil temp
Fuel Pressure Gauge (dont run a fuel line into your cockpit!!!)
I'd skip EGT since it's a way to gauge Air Fuel for tuning, if you got a good AFR or even multi channel one, this is a waste of money.
Edit:
If you decide to get those oil gauges, tell your installer BEFORE the install, unlike other gauges itll be much easier during the install of the kit (he/she will probably doing it while installing your oil return lines to the turbo).

That could easily happen in the 8, and by the time the low oil light comes on, the damage is done.

thats one of those ,if I happen to be looking at the guages , kinda thing . It is going to lose pressure pretty much instantly so most times you wont catch it in time .
The stock guage would have done the trick in that scenario ........ perhaps better because it will bring up a cel !

If I had to pick two then Boost controller and A/F Got to have both. A/f Will tell you when your running to lean. To lean under boost is what will kill your engine. I run Boost, A/F, fuel press up top and have oil temp and press running through my boost controller. I'd love to post a pic but seems like all the pictures i have are to big for the forum? Anybody know how to post pics?

I don't think you would get a CEL on the 8. Possibly the low oil level light but by then you have basically no oil in the motor. It's still questionable if the stock oil pressure gauge would do anything.

His gauges was a ProSport warning gauge so once pressure dropped it started flashing and buzzing. Bottom line is it saved his motor and without it he would have been pulling it out.

I don't know if they all do, but thanks to that post, I will definitely make sure whatever pressure gauge I get has that feature. Thanks

I thought they were just annoying at first but now it's great. I have my water temp, oil temp and oil press set to buzz when they hit their preset limits, so I don't have to constantly watch them.

No. The ProSport Premium series does, and most higher end gauges do, some Defi's, HKS, GReddy, PLX Devices, etc.
