There comes a point in the quest for more horsepower where stock side-feed type injectors simply become out-classed. BDE fuel rails work with the stock upper plenum and allow the VG30DETT to take advantage of the higher flow capacities of top-feed injectors with Bosch style o-ring ends. BDE fuel rails are anodized black and feature -6 O-Ring AN inlets/outlets for guaranteed leak-free performance while the mounting hardware is designed to prevent metal to metal contact and insulate the fuel rails and injectors from thermally conducted engine heat.

This BOLT-ON Solution allows you to use your Stock '90 - '94 Lower Plenum, leaving only the Upper Plenum, Balance Tube, and Throttle Cable Bracket to be Modified.

For your convenience, the following modified parts are available as an option below:

• Modified Balance Tube - Necessary for fitting the fuel rail's inlet / outlet (Core Charge Applies)
• Modified Throttle Cable Bracket - Necessary for fitting the #1 injector (eliminates cruise control) (Core Charge Applies)

Kit Includes:

• BDE top-feed fuel rails and mounting hardware.
• BDE bolt-on top-feed injector adapters
• Injector Dynamics (ID) Injectors (Qty 6, includes wire pigtails) - Your choice of 1000cc/min, 1300cc/min, or 1700cc/min
• -6 Hose end adapter fittings (Qty 4 included) - Zinc plated steel, includes O-Ring
• Modified Balance Tube, and Throttle Cable Bracket as listed above ($130 Core Charge applies)
• Installation Manual

What's So Special About ID Top-Feed Injectors?

• Dead time and flow rate relative to voltage and fuel pressure are fully mapped for each injector and then matched into sets of six. No other injector supplier provides this information!
• Linearity, ID injectors feature exceptional low pulse width linearity for easy, predictable idle tuning and ECU compensation for changing conditions.
• ID Top-feed injectors are available in 1000, 1300, and 1700 cc/min flow ratings (all rated at 43.5psi) which opens up the potential to make well over 1500HP with one injector per cylinder in a six-cylinder engine.
• All are E85 compatible.
• 1000s are comparably priced to OE side-feed injectors.
• The lightweight actuator allows cycle periods as low as 1.07 Ms and safe duty cycles approaching 94%.
• High impedance coils means resistors or an injector driver is not needed, the stock Z32 ECU will power these injectors (with the proper tune).

Combined, these attributes add up to the ability to use high flow-rate injectors with brutal HP potential while maintaining decent low speed drive-ability.
