With any engine modifications to the Nissan 240sx comes the need of electronics. When upgrading fuel supply for your Monster Engine, the need of controlling the fuel supply comes into play. We offer a variety of "piggy-back" and "Standalone" fuel management systems. However, monitoring the engine's tempature, pressure, and overall stability is just as important. This is why we also offer gauges that can help a tuner or driver know how their engine is performing. Please browse around and check out the products that we offer.
