Retroject 38/38 Throttle Body

Converting your carburettored classic to electronic fuel injection has never been easier thanks to the new Weber Retroject Throttle Body from Webcon.
 

Essentially, Retroject is a dual injector throttle body designed to directly replace the Weber 32/36 DGV and 38DGAS. The critical dimensions are identical (height 86mm and mounting stud hole centres of 93mm x 46mm), including positioning of throttle lever and throttle rotation, so it will be possible to remove a Weber twin choke carb., bolt on Retroject, add any aftermarket ECU and loom and a high pressure fuel supply from a Webcon WFP600.
 
Height of Retroject is the same as Weber 38 DGAS at 86mm


Wiring connections are:

Air temperature Sensor          Not polarity conscious - Electrical Characteristics here
Injectors.                                   Marked +/- on connector - Specifications here

 

Throttle position sensor         A - Ground   B - 5v supply   C - Signal - Specifications here

 

Fuel Pressure Regulator         3 Bar
 
IACV                                 

Cavity A = Coil 1 +ve

Cavity B = Coil 1 -ve

Cavity C = Coil 2 +ve

Cavity D = Coil 2 -ve


In doing so you will then have the power, driveability, torque and economy of a modern EFI system on your classic car. It really is as simple as that. No messing about with new throttle linkages, new air filters or new inlet manifolds.

 

 

Retroject is supplied complete with 2 x Genuine Weber 480cc/m PICO fuel injectors, TPS, air temp sensor, idle motor, 3 bar fuel pressure regulator,. and 2 x straight 8mm fuel unions. Please see Related Products tab for 90 degree angled ones

 

 
PLEASE NOTE.
The air intake for the IACV is blanked off during assembly by means of the top cover gasket. If the IACV is not being used, then this needs to remain sealed, however if the IACV is being used, the idle air feed will need to opened by inserting the shaft of a 3mm drill into the top feed hole until the gasket is punched through.
 
Retroject is supplied without a vacuum take off for distributor advance, however if this is required, a drilling is provided in the base of the unit, to suit vacuum take off 1053601400, and a 1.5mm hole will need to be carefully drilled through to the bore of unit. 1053601400 is a press fit in the body, but extreme care will be needed when fitting, as it is very easy to damage the brass union. Placing the union in a freezer for a few hours before fitting can help with the installation, and 1053601400 can be found in the Related Products tab


Connector pack ATB400CK contains all the connectors required to connect Retroject to your wiring harness

Retroject is ideal when using a modern engine in a kit car and EFI is needed to comply with modern catalyst requirements. It will also be ideal for off road, marine and general classic car use.
