I have tried to identify what injectors I have on my car, but I am having no luck.
The only numbers I have found seem to have been hand etched they are
9766/2 3245
Also the injectors have the Rochester RP logo on them. These are on an H22 and my tuner told me that they seem to be pretty large due to the way they reacted to small changes in the tune.
Any help?

 

this may not be much help, but there are a couple people on H-T that clean and balance injectors for money, and as part of the process provide a data sheet about the injectors. Its not free, but it might be a good way to clean the old ones and answer your question, if you can afford some downtime.

Otherwise, you might just look in to buying some injectors so you know the flow capacity. messing with unknown injectors makes things tricky when you are trying to scale a fuel map..

 

I am using eCtune so it has a feature where when you set it up it will calibrate itself for your injectors so it wont hurt me. I am just curious what I have. Thanks for the info

 

really?!? i haven't used ectune yet, but i heard it was pretty impressive.

 

I havnt actually "used" it yet either... I am installing the components into my ECU today, and will be driving sometime next week. I hope it goes well.
