1zz injectors suit the S/C just fine
Today I installed a set of 1.8L 1zz injectors that I bought off of eBay because the tC injectors that I have been using are causing CELs for a rich condition every time I start the car.
The next picture is of the blue 1zz injectors (PN 23250-0D050) going into the fuel rail to replace the grey tC injectors. The stock injectors are PN 23250-21040. There's got to be a way find the specs on these two injectors. Previously, when I was on the freeway and at WOT, my wideband gauge bottomed out at an AFR reading of 10 because it could not go lower. With the 1zz injectors, the AFR at WOT now reads 11.3 on the wideband. The following picture is of the data I logged. At WOT, ignition timing remained nicely in the double digits (here showing 16 degrees). AFR on the data logger bottoms out at 12.03. When I was running lean, I was getting an AFR reading of 14.9 on the wideband and ignition timing was down in the single digits around 8. Perhaps a little water/meth injection to cool the mixture and I'll get ignition timing up in the 20's again, which is what is is when boost is turned off. Isn't tuning fun? BTW, If you're going to do this, you can save yourself some future headaches by sawing off that nub that blocks the fuel rail from coming off. Taking off the valve cover to change the fuel injectors is not difficult but a PITA. With the nub off, it took a half hour from start to finish. Here are the injectors I bought.

Your timing looks good. Do you think 20 deg with boost is going to make it better?

Oh and nice to see an engine bay shot finally, even if it is only the boring half. |

I'm hoping that the cooler air/fuel charge will allow the ECU to advance timing some more... hopefully into the 20's. Then it's time to see dyno guy.

I was not rich in closed loop even with the tC injectors. Only during startup and boost above 5lb. I did not even have to be at WOT on the street before it went open loop.
If you look to the left of the dashed lines on the graph, most of that was on the street before I got on the freeway. I had the S/C switch set to low so I was boosting most all of that time. Light boost. The AFR during that stage is normal. I don't quite understand what forces the car into open loop after warmup.

put in my 1zz injectors yesterday. no CEL, runs great. my AFR at WOT during open loop before the 1zz injectors was about 12.4-5 now it's 11.4-5. *I was getting the 12.4-5 without the 1zz injectors because I switched back to my Stock airbox instead of my aFe intake that i had. 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. |

*edit - I recommend the AEM kit, its got an adjustable setting for when to turn on and where to ramp up to based on boost pressure, dont tap your washer fluid, its only 2.2L (slightly more than 1/2 gallon) just suck it up and put the 1 gallon tank that comes with the kit somewhere in the car. Really though between 87 octane and 93, there is almost no difference when the water/meth is working properly - and methanol in bulk is fairly cheap :)

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.
