Jenvey Ford Duratec / Mazda MX5 2.0 - Heritage Curved ITB Kit

The Jenvey Ford Duratec / Mazda MX5 2.0 - Heritage Curved ITB Kit (CKMZ04-TD) fuel-injects Ford Duratec and Mazda 2.0L engines using individual throttle bodies on an inlet manifold with a 10° downward curve, suiting angled installations such as Mazda gearbox setups. It is ideal for classic-style road, track and rally builds.

Designed and manufactured by Jenvey Dynamics in the UK, Jenvey's individual throttle body systems are prized for crisp throttle response, strong torque and the unmistakable induction sound. An aftermarket ECU is required.

Key Features:

• Built & Balanced: Supplied assembled and balanced by Jenvey, ready to fit.
• Improved Fuel Mixing: Injectors sit further upstream, in the part-throttle turbulence of the butterfly, for better atomisation, torque and power.
• Maximum Flow: Profiled spindles minimise cross-sectional area at full throttle.
• Fine Low-Speed Control: A shallow 8° shut angle gives finer control at small throttle openings.
• Proven Durability: Major components are rig tested to over 1 million cycles.
• UK Made: Cast in Jenvey's own foundry and machined in the same UK factory; castings are lighter than fully CNC-machined parts.
• Modular System: Bespoke throttle sizes and system lengths can be built to order.
• Build It Your Way: Choose your throttle actuation above. The price updates as you choose.

Features

• 10° downward curve suits an angled engine installation, such as with Mazda gearboxes
• Single-piece billet aluminium fuel rail
• Also suits Power Torque Dura-Power engines

Frequently Asked Questions (FAQs):

Q: What does this kit fit?
A: Ford Duratec / Mazda 2.0L engines, including Power Torque Dura-Power engines. Please contact us if you'd like us to confirm fitment for your engine.

Q: Do I need an aftermarket ECU?
A: Yes. Individual throttle bodies need an aftermarket ECU that is mapped to suit the kit.

Q: Which throttle actuation should I choose?
A: Most customers choose a cable linkage: single for one throttle cable, double for a twin-cable setup. The electronic actuator is for drive-by-wire systems with a suitable ECU.

Q: Are injectors and a fuel pump included?
A: No, unless listed in What's In The Box. Add them from the Complete Your Kit list above.

Q: Do I need an idle control valve?
A: It's recommended for road cars to improve drivability, but it isn't needed with electronic throttle actuation.

Q: Is this kit made to order?
A: Yes. Jenvey builds kits to order, so please allow time for manufacture. Please contact us for current lead times.

Q: Can I get a different bore size or specification?
A: Yes. Jenvey systems are modular and bespoke builds are possible. Please contact us and we'll confirm fitment and price.
