Fuel Injection 6 Cylinder & V12

Established through our years of top-quality service, E-Type UK has built considerable knowledge and expertise in both V12 and 6-cylinder fuel injection systems, which we’re delighted to be able to share with you today. Having worked to pioneer the system, E-Type UK were one of the first companies to offer commercially available fuel injection, a service which we’ve refined and perfected over the years. Working together with a small select number of handpicked specialists, we’re perfectly equipped to assist you and your Jaguar E-Type by giving your engine the gift of fuel injection for.

6 Cylinder Fuel Injection

The first time our team at E-Type UK undertook 6-cylinder fuel injection, it was on behalf of a customer. The process involved removing the existing triple SU carburettor setup and replacing it with throttle bodies, which leaves much of the engine unchanged. The key factor in this process is ensuring that the fuel injection runs independently to the remaining mechanical components.

Running the system largely independently is an asset because it ensures that fuel injection can be removed at any time, whether that is to service it, make changes or replace it with the factory correct carburation system with minimal additional requirements in the event that the owner wishes to restore the car to a more original state.

V12 Fuel Injection

Interestingly, it’s often overlooked that originally, the factory-fitted 5.3L V12 engine was actually designed to accept fuel injection. Jaguar requested that AE Brico develop the V12 engine system, which was largely owing to incoming US regulations and exhaust gas regulations. However, development stopped due to the unreliability of the system and the fact that Bosch had patents on the system that AE Brico were developing. As a result, this left Jaguar without fuel injection, thus they had to revert to Zenith-Stromberg carburettors for the V12 Jaguar engine.

You may already be aware of the fact that the V12 Fuel injection is notoriously difficult to tune and suffers from fuel evaporation, which can cause a range of issues. With mechanical skill and excellent technical knowledge, E-Type UK have used the system fitted to the later XJS as a basis, then refined, upgraded and leveraged a modern ECU to resolve the old issues, making these problems a thing of the past. 

A bespoke wiring loom has to be created for the fuel injection system in order to run the actual fuel injection, and this loom is made in-house by our team of experts. The system for the Jaguar V12 runs off modern coil packs and a ECU programmed for a Jaguar V12 E-type, which is ideal in two ways: the system ensures both greater reliability and less tuning than the factory original set-up, as well as bringing the V12 engine up to the level it was intended to be.

Thanks to our expert team and their knowledge and tireless work, E-Type UK have been able to push our fuel injection offering a stage further. We are able to offer ‘down-draft’ fuel injection, making use of a bespoke set-up, again with a bespoke wiring loom, fuel rail and throttle bodies, which we personally program with our ECU.

PLEASE NOTE, this is offered exclusively to our clients as a fitted option.

With our extensive experience and a tight-knit team of Jaguar E-Type experts, we’re perfectly positioned to offer you the highest quality service - both for yourself and for your Jaguar. If you’d like to find out more details on fuel injection, we’d be more than happy to help. You can get in touch by calling the office on 01732 852 762 or emailing Marcus on marcus@etypeuk.com.
