Replace your worn out SU or Stromberg carburettor with these throttle bodies


Using our range of SF style throttle bodies along with SU mounting adaptors you can replace many versions of the SU and Stromberg carburettors

This listing is for 1 x 40mm SF Throttle Body and Adaptor
( Throttle body includes injector mounting and mini fuel rail as shown in pictures but not the injector )



Sizes available in this range

40mm ( 1.5 Inch ) to suit SU 1.5 inch carbs such as HS4 or the Stormberg CD150
(Has the same diagonal bolt spacing as the 4 bolt versions but only uses 2 bolts for fixing )

45mm ( 1.75 Inch ) to suit SU 1.75 inch carbs such as HIF44, HIF6, H6, HS6, or the Stormberg CD175

The 45mm version can also be used for the SU 2 inch carbs such as H8, HS8

For the vast majority of SU vehicles the 45mm version will still flow enough air to support vehicles originally fitted with 2 inch carburettors
( We can source 2 inch versions but these will have an extended lead time as they are machined to order )


Throttle Body Size versus BHP

1 x 40mm body will typically flow enough air to support upto 92 BHP
2 x 40mm body will typically flow enough air to support upto 185 BHP

1 x 45mm body will typically flow enough air to support upto 115 BHP
2 x 45mm body will typically flow enough air to support upto 230 BHP

So a pair of 45mm bodies will still support power requirements for most engines originally fitted with a pair of 2 inch carburettors




Each throttle body has a tab type lever to mate and operate the next body.
For vehicles where the spacing is too large you will need make up a simple link or rod arrangement.

In many cases you can remove the linkage and rods from the existing carburettors and refit to these throttle bodies with some minor modification.
As there are so many different interconnecting links used on different vehicles we cannot advise which original linkage will fit but you should not find it a difficult task to adapt as required.

IMPORTANT INFORMATION RELATING TO THE RETURN OF COMPLETE FUEL INJECTION VEHICLE KITS


The 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.
