I don't see why it would not fit. From what I've read by other posters, the biggest problem is finding room to install the water bottle.

ask 1NZYARIS1 if the injectors for the 1.3L are the same as the 1.5L. I believe they are, in which case you can "upgrade" to the 1ZZ injectors.

The 1ZZ injectors will work great on your car.

Actually the NCP13 has the same 1.5 1NZ-FE

His is a first gen Yaris TS/RS

thanks for confirm,I will try to take off mine one to double confirm before I buy the new injector,hopefully will sort out the problem of my car and go quicker in the track,cheers

the 1zzfe injectors are about 290cc, the oem 1nzfe injectors are about 210cc, I council you the 2zzge injectors these are 350cc and are good still for future upgrade.
the 1zzfe e 2zzge injectors are bolt on for 1nzfe engine.

the one I saw in ebay also have a different number at the back as well,I guess is the year of the be made?I think as soon as it's the same colour should be the right one?

I look up injectors from a warehouse I buy from & it shows the 1ZZ injector to be a part of 23250-0D040. According to this web site http://injectorrx.com/densotf.html, the 23250-0D040 is a 255cc/24lb injector. I cant seem to find the specs for the 23250-0D050. Are you sure on the part #?

Thread necro!

Just want to add my two bits: the green 1ZZ injectors I scrounged from a 2003 Vibe (255cc) are working much better than stock. No "rich condition" codes at idle yet, can't confirm WOT readings until I get my AEM AFR gauge installed but my Scangauge II drops to 12.0 AFR as soon as I enter boost. As far as I can tell, that's all the lower it reads.

Here's verification of the stats from an injection cleaning service (witchhunter.com)


Here's a shot of them snugged under the fuel rail:


And here's a shot of the amputated valve cover nub:

Thanks for digging this thread up. My TC injectors are green also. Gonna have to check the part numbers. Thanks!

I got a set of 23250-0D040 on ebay from a Celica. Work great with the Blitz.

[AzianCuz]

So what would help me with this code?




Will these work as far as the 1zz goes?

When I was running with the stock injectors and afe intake, i had a 13.4-5 AFR @ WOT during open loop.

But now I am running the 1zz injectors and switched back to my aFe intake, and now am running the 11.4-5 AFR @ WOT openloop.

So I went ahead and ordered these, per the post:



Hopefully my lean code goes away? You guys have any other solutions for this lean code P0171?

[AzianCuz]

I've upgraded my injectors to the 1ZZ PN 23250-0D050 and it makes the car idle very good, less shaking and more throttle response. As far as the check engine light lean code goes, I haven't seen it come on yet. Hopefully it doesn't anymore.

[CrankyOldMan]

I get it once in a while, under WOT for extended periods of time. I also have a CAI and a non-standard MAF intake section, so it's possible the ECU is just getting confused. Or was it the MAF out of range? I dunno, I get P0101, P0170 and P0171 pretty regularly. My ScangaugeII clears that right up.

[AzianCuz]

Nice well hopefully I don't get codes anymore, It's annoying. Without the 1ZZ I kept getting P0171 after cleaning the MAF sensor.

[CrankyOldMan]

If your MAF is clean, P0171 means an intake leak. I've had problems with the bolts on the end of the plenum coming loose and causing vacuum leak at idle and pressure leaks under boost. A bit of loc-tite red did the trick. You should also do a vapor check--get a can of carb or brake cleaner and spray a little of it along the intake components. If the engine surges, you have a leak in that spot. If you need new gaskets for the Blitz, I may have a spare set around here somewhere.

No more CEL after the 1ZZ confirmed. Cranky is it worth it to dyno? Or could I just leave it as it and run it as my daily. I am going leave boost at medium settings and drive it normally.

Glad you got it sorted out.

You're starting to go off-topic.
If you read other threads about NST pulleys, your question would most likely have been answered.
