Good morning everyone

 

I'm mazza 

 

Its great to be here 

 

I'm hoping someone can help me identify these Mechanical injection throttle bodies

 

i was told they are from a 1970's vehicle and that was about that.. 

 

I'm familiar with a few types of mechanical fuel injection used in race cars but this one has left me scratching my head

 

Throttle bodies are marked with RDA

 

throttle bodies are 35mm diameter

it uses 4 mechanical injectors very similar to the Bosch Ke jetronic injectors

the center hole spacing are as follow:  1 - 2 (80mm)  2 - 3 (100mm)  3 - 4 (80mm)

 

 

 

 

Many thanks and kindest regards to you all

mazza
