The Jenvey Datsun L-Series large port electronic fuel injection (EFI) individual throttle body kit (ITB) has been design and developed in house to significantly increase performance and throttle response of your engine leading to a reduction in lap times for the L-Series L28, L26, L24. These engines were originally used in the Datsun L28 240Z, 260Z, 280Z, 280ZX car.

This classic car fuel injection kit includes manifold set, 3 50mm TB DCOE throttle bodies, fuel rail and air horns.

Manifold includes take off bosses, 2x ¼” NPT, 2x 1/8” NPT on top side, 6x 1/8” NPT on underside with provisions for the original linkage bar setup.

- 45mm small port kit

Kit performance is enhanced by careful positioning of the EFI fuel injectors being located further upstream than standard and directly in the part throttle turbulence of the butterfly.  This allows increased time/distance for improved fuel mixing increasing torque and power where its needed.  Our spindles profiled to minimise cross sectional area at full throttle and an 8 degree shut angle (shallower than most) gives finer control at small throttle openings.  Our kits come built and balanced ready to fit you your engine and win races.

Jenvey Dynamics design, develop and manufacture all products in house often working with leading engine builders.  Uniquely, with our own foundry, all castings are created in the same factory that they are machined and built in.  Our cast systems are significantly lighter than fully CNC parts and all major components are backed up by rig tests of over 1 million cycles.  All our standard kits are proven but our throttle systems are extremely modular allowing bespoke throttle sizes and system lengths. Please order components individually for bespoke application.

This Jenvey kit requires an aftermarket ECU.
