What size are 1ZZ-fe injectors?

[pimp my yaris]

I have injectors from a 98-99 corolla and I need to now what size they are in cc. Thanks

[xbgod]

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.

Understandable dude, didn't want you to spend undue money.

Rock-on

Three guys three answers:iono:

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.

Yes you can program up to 1000cc

[xbgod]

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 guess I will try changing to 220cc and see where my AFR is

[xbgod]

Thats what I thought.

Never tell me something is too big...I'll make fit and work anyways

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

[pimp my yaris]

The FIC is awsome I am learning so much by making my own map.

[pimp my yaris]

This is the part number if that helps?:iono:

Someone should make a injector flow chart with toyota part numbers. Mabe a bench flow testing master like cdydjded. :bow:

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.

you need these 23250 22040

[cdydjded]

Let me clarify when I say the 1ZZ's are to big. In my car, with no correction from the AEM FIC, it runs very rich. You can see what Im talking about in my profile pics of my dyno. With that being said, of couse you can use the AEM FIC to correct that problem. But here is the issue, you would have to use 1 of the fuel maps based upon TPS sensor input to correct the fuel trim when not in boost & the MAP sensor which is built into the AEM FIC to correct the fuel trim while under boost. That get very complicated & you need to find a really good tuner for that. AEM even suggests to use only 1 fuel map if possible to simplify tunning.

With that being said, I suggest finding an injector that is between the stock one's (190cc) & the 1ZZ (220cc) to make tuning much easier.

[pimp my yaris]

You can change injector size through AEM FIC software very easily and it will automatically change injector percentages throught the entire rpm and load range automatically based on the size of the injectors you are using. U dont need a seperate TPS map, but You do need to clamp the mass air so the factory ECM does not go into closed loop during boost conditions. The FIC will alter injector signals to correct levels with larger injectors even in closed loop when you are in vaccume conditions. This is how AEM recomends tuning with only one map. Its much easier and less confusing then two maps.

i am confuse what part number is the oem injector and what part number is the 1zzfe oem injector?

Should I run the F/IC-6 with 2zz or 1zz injectors?
