is it particle to install gauge for water temp, oil temp and oil pressure?

Care to rephrase the question? I don't understand.

"Is it PARTICLE..."

Do you mean, is it necessary to install those gauges?

 

sorry, I meant 'are they practicle?'
someone told me an exhaust temp gauge will be all that I need.

 

Oil temp and Pressure are very practicle

 

My personal opinion on this:

IF YOU DO NOT TRACK (track = road course)
Oil temp: I doubt you'd ever stress the engine oil to reach 130C under street conditions (if you do, you better don't, dangerous driving ) Still, it's useful to know when your car is fully warmed up. Good to have.

Oil pressure: good insurance against oil leak. If your pressure drops you'll know instantly. Important to have.

Water temp: again, I doubt you'll ever boil the water at 100C for prolonged time. Besides, you already have water temp gauge in the car. Purely optional.

IF YOU TRACK, all 3 gauges are important. Oil temp and oil pressure a must have, water temp less so but still important.

 

I think that oil temp and exhaust temp and maybe even water temp is important when your playing with boost...
