I drive a 2002 zx5 and i was wondering after i install my nitrous kit is there any pillar gauges i should get? Thanks

fuel pressure, A/F and maybe even nitrous pressure.

and maybe exhaust temp (EGR)......make sure you aren't too hot...

fuel pressure, A/F and maybe even nitrous pressure.

right on! exactly the gauges i got! A/F is wideband and the nitrous pressure and fuel pressure are electrical. very expensive! i paid over $700 for all 3!
