I have a Cosmo motor (13B-RE), and the connector on one of my injectors (side feed 550cc) is damaged. What other injectors would fit in my original Cosmo injector rails? The flow rate doesn't necessarily have to be the same.

 

The secondarys will fit if you add a extra o ring to the end of it. Your limited on the number of injectors we can use becouse they are side feed. check the for sale secton or ebays someone is always getting rid of there injectors.

 

I'm looking for primary side feed injectors that will fit in the original fuel rail. I'm all set with the secondaries.

 

A Turbo II primary fuel rail will bolt right up to that motor, and with those being top feed you have a huge selection of sizes and the availability of aftermarket rails as well. Or you could PM me, I have two Cosmo primaries I don't use.
