What important gauge you think
can be added to the stock dash?

 

for a stock car?

boosted?

you can add anything to the dash if you want to, but not nessarily in style and good taste.

the most common performance gauges are

oil pressure
EGT
Water pressure
wide band a/f

as so consider
shift light
digital display($$)

of course there's dolts that swear by monster tach on a stock daily driver, if that's your thing then go for it.

 

outside temperature for the 01-05

 

Seriously, I will be using this gauge to my Lotus super 7. I don't want any boost
or shift light. I'm only asking, aside from the stock gauges is there any thing
I need to add?
Is everything in the stock electronic dash complete?
Oil-water temp- fuel - ???

 

I would say a/f ratio is a handy gauge unless you're bone stock. In that case, EGT or water temp.

 

EGT for a bone stock car is worthless.. Only if you're using some kind of power adder that would overheat the combustion chamer. The only gauge the S could use would be none if you haven't done anyhting to it.. If you plan to track it or abuse it then you might want an oil temp gauge. The a/f gauge is cool but completely worthless if you don't have something to adjust it.

 

a VTEC indicator would be interesting. Oil temp, ^as suggested^ is a good idea too. And maybe Engine Vacuum, which is a good indication of engine load.

 

I will be purchasing a boost gauge and oil pressure gauge soon.defi gauges FTW

 

Defi's the only way to go when purchasing gauges!
