Classic Fuel Injection - Fuel Injection Conversion Thottle Body
FJAS DCOE Throttle Body - Injector mounting adaptor

This is a new throttle body set to replace the Weber Sidedraft DCOE 40

To suit
Weber DCOE 40's

Bolt spacing dimensions for flange to inlet manifold as per standard Weber DCOE footprint

This list is for a pair of throttle bodies comprising 1 x Master and 1 x Slave with mini fuel rails and the other parts you see in the photo.

( fuel rails, linkage parts, gaskets, horns etc. )

This is a cheaper option than the similar products from Webcon or Jenvey Dynamics particularly as it includes all the extras

This is a new replacement throttle body to replace the carburettor.
It looks similar to the original carburettor so the original look of the vehicle is retained.
No non reversible engine modifications are needed.

This FJAS DCOE kit contains mounting points for injectors and the fuel rails ( injectors not included)

We will be expanding our range soon to design and produce adaptors to suit a wide range of vehicles, engines and carburettor types

These kits are only suitable for vehicles with a Negative Earth electrical system.
If your vehicle is the older Positive Earth then you must convert the vehicle to Negative Earth before fitment.
Many older vehicles have already been converted but if you need to convert this is normally a simple process often cost free.

The full vehicle kits will normally be supplied with the ECU pre loaded with an initial start file.

This initial start file is simply provided as an aid for engine starting, it should not be considered a suitable final calibration for your engine.
You must be prepared to undertake further ECU calibration work to ensure the ECU files are tailored to your vehicle.
Failure to successfully complete the calibration process may lead to poor vehicle driveability or even damage to your engine.

Our Classic Fuel Injection Kits are custom built to order and to the customer general specification and as such are exempt from automatic return rights under Consumer Contract regulations.
By ordering this conversion kit you understand that further ECU calibration work will be required and the final results are outside of our control.
We cannot accept returns or claims arising from failure to successfully complete the calibration process.
