What fuel injectors for OER ITBs


ccc

Recommended Posts

first up, you need to get the physical size right- distance between the o rings and diameter of the o rings. if like my Fajs ITBs it'll be 61mm and 14mm. 

 

then you have to get the electrical connector right - if your efi comes with a harness, it'll already have connectors, probably uscar or jetronic. 

then you want to pick the right flow rate. 330cc will get you to around 50bhp/cylinder.

 

I have Bosch 0280156095 which were on european ford focus st170 10/15  years ago and so are quite cheap.

Thanks for the recommendations so far. Thought I had found ones that fit but no luck once they arrived.

 

Does anyone know how I can find fuel injectors based off physical size?

 

I measured out the fuel injector housing space and made this drawing of what I'm looking for. 16008726020331013860531611758223.jpg.2c90754760a5e526ff2d8b96fa07a6ac.jpg

I have vintage SK throttle bodies, basically the same casting as the OER.  I plan on an injector like this.

I am still trying to find the spray pattern for it.  Bosch made this model in 4 spray angles and 4 spray patterns.  

 

My plan is a single cnc fuel rail.  

 

I know people have used the RX7 injectors with success.
