Parts required for SVX Stage 2

The Stage 2 software is tuned for and requires the use of a Z32 mass air flow meter.  Z32 is the model code for the 1990-1996 Nissan 300ZX.  Both the turbo and naturally aspirated models use the same air flow meter.  The correct meter will have an orange label and a part number on that label that ends with the code "N62."  This air flow meter uses a different electrical connector than the SVX does.  The electrical connector can be acquired from a Tomei reseller--in which case it will have 5 wires, one of which you will simply ignore as explained in the stage 2 instruction manual.  If the mass air flow meter with connector is purchased directly from us it will with a harness connector with only the 4 correct wires.

The Stage 2 software is tuned for and requires the use of SR20DET 370cc injectors.  These injectors are available new directly from Nissan under the part # 16600-21U01 or can frequently be found used on Ebay. The injectors are a greyish purple color and the bottom o-ring is a small o-ring all the way down by the end cap.   The SR20DET is a 4 cylinder so the injectors are usually in sets of 4 when found used.  These fuel injectors are a direct fit into the SVX fuel rail; however, they require a different electrical connector.  You will not likely find the connectors listed as sr20det connectors.  The electrical connectors will usually be listed as 95-96 twin turbo 300ZX injector connectors.  The connectors usually come in sets of 6, complete with wires; however it is not necessary to use the wires that they come with.  Using a jewelers screw drivers or pic the wires can be released from both the SVX plugs and the Nissan plugs so that only the plastic plug needs to be changed.
