okay these came in a gsr that I got from the junk yard and can't figure out what size they are only thing on the injector is IPT 4109 buddy tried them in his and and it ran like ---- so I dunno any help would be appreciated

 

IPT makes honda injectors, as does Kei*Hin. Chances are if you swapped them and they didn't work, they were either ----, or they were not the average 240CC honda injectors, i believe preludes have 290's, and i think there's some 190CC injectors also from older single cams. (i could be wrong though) Best bet is send them out to be rebuilt and flow tested. Take a pic of them so we can see if it has OBD1 or OBD2 clips

 

I dunno how to post pics. They are obd1 thats the harness that came with the motor, I did alittle reading and saw they came in stock hondas I never knew that.
