Now based on our popular 1000 CFM 4150 version of our kit with 4 injectors to support engines of upto around 460 BHP

You will need to make or source a simple adaptor plate to suit the Rolls Royce vehicles originally fitted with Solex.
The Solex bolt pattern is slightly different to the standard 4150 footprint of this kit - we cannot supply this extra plate

Classic Fuel Injection
Premium Vehicle Kit for vehicles fitted with American V8 engines using the common 4 barrel 4150 or " Square Bore " mounting.

This listing is for the 4 Injector version of this kit with 650cc Injectors fitted

The total height of the throttle body and the injector base plate is approx 80mm ( Body = 60mm, Plate = 20mm )
It will be lower / shorter than most 4 barrel carburettors it is replacing so bonnet clearance space should not be an issue.


Complete with an included adaptor this should fit any vehicle with the standard "Square Bore " inlet manifolds.
( if you source or make an adaptor plate then you should be able to also fit this kit to Spreadbore and Solex equipped vehicles such as Rolls Royce and some Mercedes - we cannot supply this plate as it would vary by vehicle )

This kit will support many " Small Block " and " Big Block " engines from around 4.0L upto around 8.0L.

We can support engine power from around 200 BHP all the way to 600 BHP depending on fuel injectors chosen.

You can also use this kit as a base for other V8 engines such as the Rover V8 but you may need to make changes to the adaptor and / or manifold

These Throttle Bodies are normally Silver in colour as per the photos but occasionally due to availability we have to supply the Black version.
Other than the colour they are exactly the same specification.

We cannot supply based on colour choice and orders will be fulfilled using the current stock.

This kit contains all the parts needed for our Classic Fuel Injection system
(you do not need to order anything else from our range )

This Premium kit will suit most V8 engines fitted with a 4 barrel carburettors.

This kit comes with a new 1000 CFM 4 barrel throttle body to support the common 4150 flange carbuettors.

Along with our custom adaptor plate that holds the Fuel Injectors and Fuel Rail with hosetails for Idle Air Control and MAP sensor this assemby replaces the existing carburettor and is normally a direct bolt on replacement to looks visually similar to the original carburettor.

We have assembled this kit for easy ordering but if you prefer you can still order some or all of the parts using our individual listings

Ordering our kits will also save you money, our kits are typically 10 to 15% cheaper than ordering individual parts
