This adjustable fuel pressure regulator kit is a new product specifically designed to work with tuned turbocharged cars with fuel injection systems. It's been built to cope with the higher boost and fuel rail pressures needed for high power cars unlike other products on the market which are really operating on their outer limits. It allows you to fine tune your fuel rail pressure and increase it from the standard pressure in order to squeeze more fuel out of your injectors. Fuel injectors like many other parts have room to squeeze more power out of them and can safely run at a slightly higher than rated pressure, which means more fuel flows for the same injector opening time.
This can be usefull if you are experiencing high duty cycles, but don't want to shell out for larger injectors.

This kit includes an adapter for the Nissan fuel rail, external fuel pressure regulator as well as the pipework and brackets needed to mount and fit it.

We would recommend using a gauge when setting the fuelling up as it removes a lot of the guesswork and the possibility of causing damage by running too high a pressure. The gauge should be removed once the setup is completed.
There is a connection on the regulator for fitting a gauge and we can provide a suitable 1-7bar gauge for an extra £16
