They're around 200cc, but hey I told you I would get you those injectors as soon as I get in. So don't go wasting your money. Those Precision Injectors I have are 380cc and cost around 450.00. You will not find a better injector than Precision. they are flow matched, meaning you will get exact amounts of fuel per cylinder.

240-260cc.

I'm thinking they're most likely 260cc though.

Take them to a place that can flow them. Guessing is not the way to go. I can assure you that the 1ZZ injectors I have flow 220cc. But they came from a Toyota Celica not a Corolla.

xB: 380cc's are too big for our use. I have the 1ZZ's & they run very rich.

I already had these injectors. And I was under the impression that 1NZ injectors were 190-200cc. The problem is I am allready runing lean in the 5-6K range. So I wanted to install these until I recieve your larger injectors. Believe me I appriciate it very much.

1zz must be larger then 200cc though. I just want to program my FIC correctly.

And you don't have to run the full duty cycle of the 380cc injectors, thats what your fuel management is for.

I would hope with the AEM/FIC you could control a 380cc injector.

Pimp,.....I'll make a personal call to Greg Nakono over at AEM for you. I'm pretty sure you can control those 380cc injectors. Then you'll also have room to grow.

I'm 680cc yeah...I have full-standalone but controlling a injector shouldn't be an issue.

I know the FIC can handle it and I know how to calculate for larger injectors. I was just looking for flow rate on 1ZZ 98-99 corolla injectors

Thanks so much for the link. Unfortunatly my part number is not listed. The closest one 23250-22040 says 255cc. Any way I put them on my car and it still goes lean. These injectors seem about the same as stock. I recalibrated my FIC map from 200cc to 220cc and my AFR got leaner across the entire rpm range. So not big enough. For now I returned back to 200cc calibration, until I get bigger squirters. O well it was worth a shot. Everyone should save those links.
