Lotus Twin Cam Heritage Fuel Injection Kit

Bookmark or Share

Carbs can never be jetted correctly for every engine condition and the usual compromise is to jet correctly for full power, sacrificing accuracy at mid rpm and mid throttle.

A fuel injection package can deliver precisely the correct amount of fuel for every engine condition (as well as offering all of the advantages of electronic ignition). The result is an engine that is smoother to drive, picks up more cleanly, and depending on how the original carbs were jetted may even be more economical.

However, many people like to retain the originality of their car and a modern fuel injection system can sometimes spoil the period look. To that end, we can now supply a kit that uses the Jenvey Heritage throttle bodies. These throttle bodies are made to look like and be a direct swap* for DCOE carbs, keeping all the modern parts like injectors, wiring and the throttle position sensor hidden away under the top cover.

A typical package includes:

  • DTAfast full management ECU** (and engine bay wiring loom)
  • Toothed front pulley
  • Crank speed sensor (and mounting bracket)
  • Water and air temperature sensors
  • Twin coil ignition pack (with distributor blanking kit and plug leads)
  • 45mm DCOE "Heritage" throttle bodies (with throttle position sensor, 350cc fuel injectors, 40mm trumpets and both push-on banjo and -6 fuel fittings)
  • Fuel pressure regulator
  • High pressure fuel pump
  • Fuel filter

This is the base kit, the parts that everyone will need. Depending on the application, you may also need the following which are available seperatley:

  • Fuel line and connectors/finishers
  • Swirl pot and low pressure pump
  • Throttle linkage kit
  • Air filter and backplate

NOTE: The kit comes with plug leads but you will need to supply us with measurements of how long they need to be for your application, depending on where you will mount the coil pack (you can tell us this later once you have the kit mocked up, if you wish).


*they will bolt directly to a DCOE flange, you may need a new throttle linkage, original airboxes or air filter backplates will fit with slight modification

**ECU will come loaded with a base map which matches your setup as closely as possible. However, this, as with all generic maps, will still need fine tuning on a dyno.
