Porsche 911 2-bolt Heritage ITB Kit 35mm port

Details of Base kit

Completely designed and manufactured in-house by Jenvey, the new Porsche Air cooled Heritage kits are a natural progression to the exceptionally successful DCOE Heritage Throttle bodies released in 2017. They boast all the plus points associated with Individual Throttle Bodies (ITBs) kits, yet manage to marry these with the subtle, understated looks of a period carburetor induction set-up – ensuring that it won't look out of place in the engine bays of classic and retro vehicles.

The advantages of modern, electronic fuel injected intake systems are simply too hard (and too numerous) to ignore, with some of the key facets being a reliable, unbroken flow of air, extremely accurate control via advanced standalone ECUs, easy starting in all seasons, and of course, more power and economy. The sole downside on a classic installation, up until now, has always been the aesthetic – something that the Jenvey Heritage Throttle Body solves with its retrospective exterior design and exquisite engineering.

Jenvey has made sure to offer the Porsche Heritage Throttle Body kits for the 2 bolt engine with 35mm and 39mm port sizes married to a 42mm and 45mm throttle body respectively.

This classic car fuel injection kit includes manifolds, throttle bodies with injectors, tps and integrated fuel rail, linkage, air horns & loom sockets.

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.
