I just recently upgraded my stock 265 cc injectors with supra 7mgte 440 cc injectors I'm also using a pallnet 11 mm fuel rail and a Godzilla raceworks mega squirt II my car run great before and now hard to keep it running even after tuning, my question I'm using connectors from 280zx set up they fit ok but is there a difference between connectors for Datsun injector and a supra injector if can someone let me know which ones i need and where i can get, I'm extremely frustrated and any help would be appreciated

Thanks Tony
