Default OBDI 2JZGE & 1UZFE Injectors Interchangeable?

Really want to get my car back on the road, but I have 2 leaking injectors on my 1uz(even after replacing the orings). I have immediate access to 2jz injectors, but I am unsure if their spray pattern, resistance & flow rate match. Donor injectors would be coming from a 94 2jz into a 92 1uz if all is well. TIA

they will physically fit and plug up, however the sc300 inejctors are 330cc and the 1uz injectors are 250cc.

I would not even attempt this at all unless you are changing all 8 to sc300 inejctors.
If you change lets say 2, they will be running rich on those cylinders until the o2 sensor corrects, but the o2 is an average of 4 cylinders on a 1uz, so when it corrects the 2 normal cylinders will be running lean, and the 2 ones with new injectors will still be running a little rich.

the mk3 turbo ones are even larger 440cc. you can put in any of these you just need to put in all 8, you cannot just replace some of the injectors with larger ones unfortunately, but I would think you can get replacement 1uz injectors pretty easily.

Injectors don't seem too expensive to replace....
A quick search

Thank you very much. Seems like the sc3 injectors are a mild upgrade & the mkiii are a significant upgrade. Since I'm not in need of more fuel, I'll stick with the 1uz injectors for now. The inquiry wasn't due to lack of availability of 1uz injectors, but more the fact that I have my ex's 2jz rotting away in my garage. I may nab those injectors for later use though.
