I'm going to be installing either a Greddy TT or Turbonetics shortly- what gauges do I need beside the boost gauge?
Air/Fuel
EGT
Oil Press.
?

 

Oil pressure and temp gauges are quite important, especially on an engine that is not specifically engineered to be turbo.
AFR gauge can be a good investment, but be advised that there are heaps of useless, crap brands on the market. I would definitely suggest spending a little extra to get name brand units.
There are quite a few more guages that you can get, how many are you looking at running?

 

A wideband O2 is the most important after boost.

 

Defi boost, oil pressure, egt and Innovate wideband afr is what I am going with.

 

I don't know how useful EGT is now that the AFR gauges are so good these days. Between Cipher and my TXS unit, there's 3 widebands providing constant A/F data.

Boost, A/F, oil pressure, and water/oil temp gauges is what I would go with followed by fuel pressure (for debugging in case something goes wrong)...

 

+1 I have A/F, Boost and Oil Pressure. For A/F wideband you can't go wrong with Innovate

 

What turbo y'all have or are going with?
Greddy
Turbonetics
Vortex Supercharger
Stillen
SFR

 

I would say that fuel pressure, oil pressure, egt, and wideband are important. These should be mandatory as they will show the health or lack thereof in an instant.

 

Don't you want a Boost Gauge? I sure hell want to know if I'm overboosting. If I can only pick 3 then Boost, Wideband, and Oil Pressure will be my top choice. 4th will be EGT 5th Oil Temp or Fuel Pressure. JIMHO

 

My G is actually in the shop right now having a Vortech SC installed along with the gauges I mentioned above.

 

I figured that was a given but yes I would want a boost gauge. If you get a 4th gauge, make it an egt. This is very function in tuning and monitoring.

 

Ok since gauges vary on owner's preference I wish there is more choices on Pods. I don't really care about pillar pods coz it attract more attention and don't want to put in on my glove compartment coz visibility is poor and dangerous especially on WOT.
