Default I need three Gauges... which to buy?

I'm looking to do some mods soon and I want to buy gauges. I know that I want Auto meter. I was thinking: boost, oil press, and EGT. Which three would you buy? Who sells Autometer for least?

Default which 3 gauges to buy

That is exactly what i would and did buy.

I bought the following in matching ultra lite 2 1/16th trim:

Oil pressure 0-100psi
Boost -30-25psi
EGT 0-1600 degrees

I would not buy the Autometer Probe for the egt it is overpriced, so i bought a nice type K probe from www.westach.com.

good luck

Default u got it!

those are the 3 main gauges (also ones I currently run) you want to have in a turbo car, now I still monitor A/F ratio /engine temp/air temp from my ecu as well...

You guys forgot one..... kinda important.... Air fuel.

Although good ones are expensive, they are more then worth it. A/F is what makes the car go. EGTs are an effect of a couple different things. EGTs are affected my timing and A/F (a little) and knock. Still a valuable gague, but I would take the A?F over that oil pressure gauge. Easily. Why do you need an oil pressure gauge? You are modding your car. You should be checking the oil every time you put gas in it. If there are any leaks, you will know cause you are modding your car and paying attention to every single little detail. If you don't return your car to stock because your going to blow it up. Sad truth.

If I had to pick three gauges, and only three... hmmm... Boost first and foremost ... then either fuel pressure or EGT your choice ... then a quality A/F gauge. GReddy currectly has one of the better ones on the market but its 165 bux ... hmmmm

Thanks for the info guys.

EJ20WRX….how much was the probe? Did you get the clamp-on version? The Autometer one IS a bit expensive.

I also have what EJ20WRX has.
Boost / EGT / Oil Pres.

Now - from what I understand, the EGT gauge is useless without a good probe. Autometer sells 2 probes - that you have to order seperatly from the gauge. (found that out after I ordered the $100 gauge - thinking that the gauge / probe combo was "cheap".) One is the "regular" one, and one is the "professional". $80 - $90

EJ20 - how are the westach probes? I know you recommend them for being "inexpensive". Are they just as accurate?
I can't see the price / part number on the site - can you provide?

Thanks,
Kris

Why the heck do you REALLY need an oil pressure gauge?

Boost, A/F, and EGT are the most needed. MAYBE an oil temp.

Why oil pressure? Because if your engine starts to overheat, the oil pressure will go down. Conversely, when your engine is cold oil temp is high and you can tell by the oil pres if your engine is warmed up. So, with the gauge you should be able to prevent damage to your engine by avoiding pushing it too hard when it's cold, and know immediately if there is a temp problem and can back off. Water lags behind oil temps and is thus more removed/takes longer to react.

EXACTLY! All the information you just told me can be gathered from an Oil TEMPERATURE gauge. so again; why do you need an oil pressure gauge if you aren't a FULL-ON-DON'T-DRIVE-IT-ON-THE-STREET-CUZ-IT'S-A-RACE car? I say the $$ spent on an oil pressure gauge is more useful elsewhere.

Someone prove me wrong.

i think the main arguement for a oil pressure gauge is to monitor any oil starvation. each to his own. i guess what you REALLY want is what you REALLY want to monitor. of course it's a good thing to know what's happening to everything at the same time.

i guess westach makes a good compromise by making dual, triple or quad gauges for control freaks out there.

i've got Boost, Oil Temp, and i'm getting EGT.

i have an AF, but having seen one work, and then learning more about what EGT's tell you, and the fact that local subaru dealers want to void my warranty if i have the A/F (but surprisingly not with an EGT), i'm changing my mind.

anyone want to buy a carbon fiber Autometer A/F ratio gauge?

also, the best place to use the A/F gauge is on the front O2 sensor. problem: the autometer reads a 0 to 1 volt signal. which is likt what comes off the rear sensor. the front sensor is a wide band O2 sensor. they don't mix. Larry at SubaruPlanet.com can hook you up with a converter so the front sensor can be used.

another way around the problem is to just weld in another sensor at in the earlier inthe exhaust stream. you can get that done for about 60 bucks, so i've been told. the sensor can be found at NAPA or the like. also, that way, you never touch the suby sensor, and can't fault it (somehow) and void your warranty. take that Mr. Dealer.

(rhetorical statement: i don't understand how you can weld new parts to your car and not hurt anything, but a PASSIVE signal reading add-on voids the warranty on the sensor, and potentially the ECU...what a load of crap. silly subaru for using fragile sensors on a RALLY INSPIRED car. silly, silly.)

Actually, check out Shiv's recommendations - he seems to thing that Boost, EGT, and Fuel Pressure are the most important - and I tend to agree. I'd dump the Oil Pressure and go for Fuel Pressure - that should make it easier to tune, and you'll see any FP problems that could lead to det.

Default Mounting

SubyPrez - Thanks for the link to the pictures.

I have yet to see a really clean install of the gauges. Does anyone know of a 52mm or 3 2/16 gauge pod that would make installing the gauges easier? Or, if there is a company that sells the gauges we are looking for in 43mm so we could use the stock pod?

I think Kris's install of the Autometer gauges pictured below mine on that link are some of the cleanest out there. Give them a look...

okay, i think this what is considered clean install:



this is my setup in my MY00 RS. it was a lot of work manipulating the housing but is definately worth it.

what is the size of the opening on the WRX gauge housing, is it the same size opening as on the 1rs gen RS?

if i can help out in any way please let me know, because i am purchasing my WRX later in the year and this is a must do mod.

here are my instructions for my pod, maybe ideas can be gathered from them:




justin

these are the style gauges i plan on putting in my WRX because they closely match the stock instrument panel color scheme:

Autometer Ultra-lite carbon fiber 2-1/16" gauges.

Arrow Back on topic...

Q: Why oil pressure? A: Okay - first let me say that if I could mount an unlimited number of gauges in the car, I would work from this list in order... Boost / EGT / Oil Pressure / o2 / Water or Oil Temp / Fuel Pressure / Intake temp / etc. So o2 (Air Fuel) is up there... But I only can pick 3.

Boost is a no brainer. - Turbo car.

EGT is closely related to boost, and safely hitting the maximum without hurting the engine. Turn up boost = Hotter EGT's = Engine Damage. Plus it gives a more averaged reading of rich / lean.

O2 / Air Fuel is a gauge I can't stand watching. Because the ECU is working a closed loop system, and is constantly adjusting the ratio, it pegs back and forth from rich to lean... Unless you are at full throttle you don't get a "averaged" reading. rich......lean.......rich.......lean......VRRRRROO OOOMMMM....rich...rich..lean....rich. "I think I've gone crosseyed!"
It's still a valid gauge to get - and we are talking about personal preference here...

Loss of oil pressure = engine damage. Oil is even more important in a tubo engine then in a NA. Now oil temp is important too - but we're splitting hairs. I know someone who killed their engine because of a sudden loss of oil pressure. The idiot light never came on, and the motor was done for.

So I agree that the last gauge of the 3 is pretty much personal preference... Oil Temp, Oil Pressure, O2, Fuel Pressure. I had oil pressure in my last Impreza, and I like to monitor the pressure during startup as zzyzx pointed out...

Suby - Thanks for the compliments. I worked hard to get them finished. Now I just need them to cross ship me a boost gauge that's not broken

Joostin - I like the look of the gauges behind plexi! - I was considering something like that too. Less modification of the pod is needed for it to work. Detailed instructions - cool.

Thanks guys - Kris

i am here for you, i cant wait to get my REX. i love my RS, but a REX!

took a while to get the detailed instructions together but it was worth it. i also have the instructions i got from Rallispec to tap for the oil pressure sending unit if those are also needed.

i absolutely love the plexiglass, it makes it so look like it is supposed to be there.

so i am sure we can make a great pack. like i did for my RS, it took me about 22 hours total for the install/put together. time well spent. so figure about the same more or less time for the WRX pack.

Jgrahn555,

Not that I'm concerned in convincing you, but your logic needs a little twisting. If you can reply here and now and tell me the breakdown temperatrues (temps as which the oil fails to lubricate) for the following oils:

Mobil 1 15-50
Castrol 10-30
Valvoline 10-40

...then, my friend you are much smarter/informed than I. I cannot. I can, however look at an oil pressure gauge which will tell me if the oil is becomming ineffective due to heat. Perhaps you are making an assumption that all oils will operate the same at a given "oil temperature"? Well, I'm not.

Granted, this is not a good tuning metric to look at, but more of a safety valve.

- Steve

Okay, to get nit-picky; 1st of all, you're using different brands and grades of oil. Maybe if you stuck with one brand, blend, and grade, you wouldn't have enough problems to need an oil pres. gauge. And you didn't specify synthetic or not, so these are all synth.

Mobil 1 15-50 breaks down at about 430 F.
Castrol 10-30 is at 415.
Valvoline 10-40 is crap. Don't use it.
and just for giggles:
Amsoil 10w-30 has a flashpoint of 480 F.

Thank you, there 3 shows a day, the 1st one is the best, be there or be square!

Oh, and did you ever consider transmission oils too? Hmmmm....

Bottom line: Oil Pressure NOT WORTH IT.

For everyone else:

Cool, thanks for the link. You are the man, I suppose. And no, I don't use different grades, I just wanted to point out that a gauge - used by many different people - would have to be read differently depending on the oil they use. That said, with the info you provided (and a sharp eye and memory...) the two can be used to know when you might have an issue. I will stick with oil pressure, thanks.

- Steve

P.S. Yes, Valvoline is crap, though that doesn't seem to stop people from using it. I use Mobil 1.

I'm not going to argue with this one, but i will bring up the fact that no honda team (that i am familar with) are sponsored by Valvoline nor run Valvoline by choice.

Valvoline is a cheap oil that - works -... As in, it'll do, and it's inexpensive, but its not the best. it doesn't perform well at all. If you check out that link i posted and scroll a way down, you'll see that Valvoline just doesn't rate in comparision with other brands.

Oh, not to admit self-defeat or anything, but after an extensive talk with a co-worker of mine, i ALMOST agree on the necessity of an oil pressure gauge... I guess it moves up to #4 on my list...
