Everyone knows how essential it is to get fuelling right on turbocharged cars! So if you are running a tuned JZZ30 Soarer with the 1JZ-GTE engine, you need one of these genuine Italian Malpassi adjustable fuel pressure regulators. Essential where cars are running with aftermarket tuning parts and above stock boost levels. Unlike some cheaper regulators these are properly referenced to the manifold pressure. As the manifold pressure changes (vacuum on cruise, higher pressure under boost) the injectors are 'seeing' different pressures, but the ECU fuel maps are configured for a steady state. The vacuum take off means our fuel pressure regulators constantly adjust the fuel pressure to suit the ambient pressure inside the manifold- keeping your chosen fuel pressure secure and accurate. For tho.
