Sorry about starting a new thread about gauges but I was wondering about the most important thing when it comes to monitoring the engine. There's a lot of gauges out there. For example, water temp, oil temp, oil pressure, fuel pressure, exhaust temp, intake manifold pressure (na), and boost. Besides for show, which would you suggest or in other words, how many gauges does it need for the Evo?

I'm thinking of just the boost, water temp, oil temp and fuel pressure gauges would be enough.

Again, thanks for your help guys!
