Nissan 240sx with a turbo

[GooeyStuff]

I have several questions,what kind of maintenance should i be aware of(besides the basic e.g.fluids, filters, and belts)of this car, so it would be running at it's optimal performance?

A friend installed a air to fuel ratio gauge and a turbo boost gauge, powered (on/off) by a toggle switch. Is that the only way of installing these gauges? The toggle switch is an inconvenience because i can't use the auto start and i have to waite in the car until the turbo timer turns off. So the question is, can these gauges be installed professionally without a toggle switch, so i could be able to use two of the car's features?

Thx..

just wire them to a switched 12 volt source. throw the toggle in the garbage. i dont know where your gauges are, but the radio is a pretty easy place to tap into a 12 volt source. just bust out the multimeter, turn the key to accessory, and see which wire coincides with what youre doing with the key.

turbo wise, you need to research that. i dont know if youre going ka-t, or essarrrr. either way, go to those specified forums, and search/read.
