This adapter kit allows you to install new style Z32 pintleless fuel injectors into an early style Z32 fuel rail.

"Early style" fuel rails and injectors were used in the 1990-1992 Non Turbo, 1993 Convertible, and 1990-1994 Twin Turbo models.

"New style" injectors and fuel rails were used in 1993+ non turbos, 1994+ convertibles, and 1995+ Twin Turbos.

When replacing fuel injectors in an earlier model Z32 we recommend upgrading to the new style injectors.  They are more reliable and resistant to electrolysis caused by ethanol content often found in gasoline today.  Popular injector upgrades for twin turbos such as the Nismo yellow top 615cc and red top 740cc are only produced in the new style.  In order to install these performance injectors into a 1990-94 TT engine you'll need this kit or an aftermarket fuel rail. 

The adapter kit allows you to use new style injectors in an early style Z32 engine without having to machine the lower plenum or use expensive aftermarket fuel rails. You will need to clearance the number one injector bridge about 1/4" to fit with the new injector plugs.

  • 6 Aluminum Injector Caps
  • 6 Aluminum Lower Injector Adapters
  • 6 Lower Injector Adapter O-Rings
  • 12 Stainless Steel Hex Head Bolts
  • 12 Stainless Steel Lock Washers
  • 1 Tube of Silicone Lubricant


  • 6 Injector Plugs (electrical connectors)

 The optional wiring harness connectors are necessary when installing new style injectors into a Z32 with a wiring harness that has the connectors for the early style injectors.  These kits include the o-rings required for installing the adapters but do not include upper and lower injector o-rings, or fuel rail to plenum seals.   The additional o-rings and seals needed can be found HERE and select the option at the bottom titled injector adapter supplement.

Response: It doesn't matter which goes to which, just stagger & insulate the connections so they cannot short out easily.
