FORD DURATEC - Heritage Curved ITB Kit

Mazda / Ford Individual Throttle Body (ITB) kit for fuel injecting your Ford Duratec / Mazda 2.0L with a 10 degree downward curve which compensates for angled engine installation, e.g. when using a Mazda gearbox. This classic car fuel injection kit includes  inlet manifold, a pair of TB45 twin throttle bodies, a single piece aluminium billet fuel rail, 40mm long airhorns and blanking plugs for the standard injector ports. Ideal for road, track or rally use.

Please note that this kit requires bulkhead modifications when fitted to a Mazda MX5.

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.

Option and Accessories

Throttle operation can either be with a cable linkage kit or electronic throttle actuator.  (CLS3 / ETA2-TB)

An idle air system can help make road cars more useable but is not required with electronic actuation

The base kit includes 350cc injectors which can be upgraded to larger 730cc or smaller 250cc options. – see our injector sizing chart.

We recommend using our individual mesh filters which clip onto the top of the heritage air horns.
