Nissan 300ZX LED Boost Gauge

Install Your Own Custom In-Dash 20 Indicator 20, 25 or 30 PSI Boost Gauge (300zx TT)

In Dash 0-20 PSI Boost Gauge Kit and Plans (Nissan 300zx Twin Turbo)

This boost gauge kit includes everything you need in order to build your own accurate (+/-  0.250 PSI) fully functional turbo boost gauge.

This unit also includes custom "Dimmer" technology that automatically dims the indicators for night time driving to an adjustable pre-set level,  when you turn on your car's master light switch. The night time brightness can be adjusted to suite individual requirements.

An accurate "Real Time" boost gauge is an absolute must, especially if you have done any non stock performance upgrades to your car. Such as; installing a new chipped ECU, increasing turbo boost settings, adding boost controllers etc. This unit takes the signal from your car's existing pressure sensor and monitors the boost pressure "Real Time".  Results are reported on 20 LED indicators with an accuracy of approximately +/- 0.250 of a PSI when setup correctly. Calibration is easy to do and default components are provided for sea level operation. The circuit is flexible enough to be configured for any altitude if needed. You can mount the Indicators anywhere you like. But we recommend putting them in the existing tachometer dial in your car's instrument cluster.  This is not too difficult to do and is discussed in detail in a dedicated article on this web site under Nissan 300ZX Twin Turbo.  Yes, they can be fitted right into the car's dash board. As you can see from the example photograph below, 1 indicator corresponds to exactly 1 PSI. 1 to 25 respectively. Other customized boost readings are also available up to a maximum of 30 PSI. The complete unit is so small it can easily be concealed behind the dash.

External computer grade sensors are required, as it has been found that 90% of the stock sensors are slow and very inaccurate.

Here is a photo of a finished tachometer mounted in the car's cluster ready to go. If you click on the photo you will see it in action. The colors of the indicators can be customized in any combination of Red, Green, Yellow Amber & Blue.
