After market Gauges

[Stank]

I know It's possible to replace all gauges on my dash to after market and probably easier with the SR20DET swap. But first, does anyone know the specs for any of the gauges. Most should be simple, Tach, Water Temp, Oil Press, Boost, Volts. The ones I have issues with are, Fuel and Speedo. The fuel Gauges go by ohm readings, and I believe the Sr is an electrical speedo, but I have the Cable from the KA still. If I can get some help I do a write up on it when I'm done. This is the only pic I can find of someone doing it

geez. This one has me stumped.

Can anyone help a fellow truck owner with an answer here?

Would that be in a shop manual?

For the fuel level, I would get a kit from summitracing or equivalent that you drop into the fuel tank and adjust the height of the float for the depth of your tank. If your d21 tank is anything like my 98 frontier tank, it is just a rectangle, no strange curves or anything, so you could easily pick any number of spots to make the assembly bolt in to the stock tank. Otherwise, you can modify the stock float to give you the desired resistance range.

As for the speedo, you can do it two ways. You can use the ka cable and buy a mechanical speedo. You would just have to purchase a speedo cable adapter to connect the ka cable to the input cable on the gauge. If the cable does not read accurately because Nissan may use a different cable speed than autometer etc. then you can get a correcting ratio drive joint from an autoparts store or Auto Meter.

The other, and much better way imo is to use the sr electric sending unit and buy an autometer eletric input speedometer. These are pre-calibrated for 16,000 pulses/mile hall effect senders. If the reading is off you can recalibrate it fairly easily. Read these two pages to decide which route sounds best to you:
