Terra Firma Automotive supplies genuine Nissan fuel system components that restore factory performance and reliability to your Z32 Fairlady or 300ZX twin-turbo. This early 370cc fuel injector is the exact OEM JECS unit engineered for 1989–1994 VG30DETT engines. It delivers the precise fuel flow, spray pattern, and response characteristics Nissan specified for these high-output twin-turbo motors, ensuring accurate fuel delivery under boost, smooth idle, and strong throttle response across the entire RPM range.
Early twin-turbo Z32 owners know that aged or failing injectors can cause lean conditions, hesitation, rough idle, poor boost response, or even engine damage under load. Replacing with this authentic 370cc injector instantly restores factory-calibrated fueling, crisp drivability, and safe operation whether you are refreshing a high-mileage daily driver, rebuilding a performance engine, or maintaining an original low-mileage example. Its precision internals and durable construction provide consistent flow and atomization that aftermarket alternatives often struggle to match long-term in the demanding high-heat, high-boost environment of the VG30DETT.
At Terra Firma Automotive, we are the trusted premium source for hard-to-find OEM fuel system parts that serious enthusiasts and professional builders rely on. Whether you are addressing fuel delivery issues on your early twin-turbo, refreshing the complete set during a top-end rebuild, or completing a detailed engine bay restoration on your 1989–1994 Fairlady Z or 1990–1994 300ZX, this early-style injector upholds the legendary engineering and performance that define these iconic Nissan sports cars
