I am a newbie to turbochargers and will be bringing my car in June 7th to Scionspeed to finally have my stage II turbo installed. I am currently trying to get most of my parts bought, so when that day comes I can bring them and have them installed. I was wondering which gauges are absolutely necessary and need to be monitored. I will be putting an electronic boost controller (greddy profec B-spec II), so I assume the boost gauge isnt necessary ? Or is it ? Then what else is needed ? Oil temp gauge? Volt meter gauge ? air/fuel gauge ? water temperature gauge? Also I want these gauges to be decent looking, and not too expensive, with some type of holder to put in the in dash or under the radio unit of the car. Anyone know of any reasonably priced, nice looking gauges or gauge holders ?

always have a boost gauge just so u can see what ur car is holding and spiking and other gauges arent really necesarry

Hey, a boost guage will be needed. Other guages that you might want to put on would probably be a oil pressure guage, fuel pressure guage, and exhaust temp guage. Since the tc did not come stock with a turbo from the factory, getting all the guages you can get to moniter your car will be helpful. Cars that come with turbo stock from the factory has only a boost guage because their engine is built for turbo, with lower compression pistons, better fuel systems, exhaust manifold, etc.

A must it an EGT guage along with a boost gauge, also a air-fuel ratio would be ok if you want to see if you car is running rich or not. But thats what I recommend.

In my opinion there are four essential gauges with a boosted car:

- Boost (you can see if you are spiking, etc, overboost will kill a boosted engine faster than anything!)

- Oil Pressure (if something goes wrong internally, your oil pressure will be the first indicator. If you loose oil pressure, you can imediately shut it down and find the problem.)

- EGT (especially in boosted cars that were NA from the factory. No matter how good of tune you have on the car you will want to know where your EGTs are at all times. Like if you are going up a hill and doing a long pull in 4th gear, which is when most people blow their engines by the way, your EGTs will shoot up before some thing major happens and you will be able to let off the gas before you melt a piston.)

- Wideband O2. (Don't waste your money on the narrow band light shows, they won't tell you much about your AFR. Get a nice wideband so you can monitor your AFR and make sure you are okay. This will also alert you if an injector goes out or your head gasket is leaking, both of which would cause a temporary lean condition that could lead to engine failure if you don't recognize the problem right away.)

Those are my votes! Happy boosting!

yea egt helps alot too good call matixten

The Profec is a boost gauge, you don't need to buy that one. EGT and whatnot is up to you...

I agree with what has been said.

In order of importance...
Boost
EGT
Wideband A/F
Oil PSI/Fuel PSI (both about as important in higher hp setups...)

Yepp, the main ones are boost, EGT, and oil.

Autometer makes a wide array of sizes and options. Reliable in my experience and worth the price.

Good luck

I have boost, oil pressure and my wideband, along with the Profec.
