minimum gauges you would want are A/F and boost.
people buy gauges for a reason though. If i would have had an oil pressure gauge on my turbo prelude, i would have saved about 300 dollars and 20 hours labor.
Prices listed are for autometer, which is basically the bottom of the line as far as FI worthy gauges go
Oil gauge = $60Turbo repair/rebuild = $275Engine, transmission = $125 (thank god for good friends)
A/F gauge will give you an idea if you are running lean or not. If something goes wrong with your fuel pump and you run too lean, say goodbye to your bottom end A/F gauge = $55
Wideband gauge $500-$600. Replaces A/F gauge but lets you squeeze a lot of extra horspower out of your setup via tuning. Say goodbye to fuel management guesswork and fouled plugs from running too rich. This kind of at-home tuning could easily net you 50 hp on a nice setup.
Fuel Pressure Gauge $200? Running lean is bad, it makes stuff break. Im relying on my wideband in place of this
EGT - $150. Im not an expert on this, but gives you an idea if you are running lean and/or running too much timing.
Boost - $50 Tells you how much boost is reaching your intake manifold. No, your car isnt running 'faster than usual today' you've got a hole in the vac line that goes to your wastegate and you're running 5psi too much. If you had a boost gauge, you'd have known that already
