Porsche 911 2-bolt Heritage kit 39mm port by Jenvey

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.

The base kit includes manifolds, throttle bodies with injectors, tps and integrated fuel rail, linkage and air horns.

Competition Systems also has all of the additional parts to create a high performance EFI retrofit including ECU's, engine wiring looms, EFI retrofit distributors and all sensors required. We also have a lot of experience in installation and mapping this sort of system.
