    Swapped to Corolla/Matrix 1.8L injectors today, Corolla part #23250-21040. Perfect fit: runs just fine without a tune, although I do plan on getting one soon. Only negative was a roughly-tenth of a second increased lag or hesitation off the line when at low idle. Its negligible though worth noting.

    There is a noticable increase in torque in the low end when the engine is already under load otherwise
    though. Slightly more burble after revs as well.

    Took about 30-35min total, only needed a 10mm, 12mm and an 8mm for the pipe clamp on the intake, and some towels for the gas that spills out the fuel rail, though it was only about 2-3oz. Don't overtighten the fuel rail bolts on reinstall; the plugs won't sit right if so.

    Once the intake and EGR valve connection were off it was smooth sailing.

    All current mods are listed in my profile description.

    gotta get a better obd2 device, mine only allows me to read/clear thrown codes; although none were shown after the swap, it was as seamless as could be. Id still like to get everything checked and tuned though just to make sure its all good. To my surprise im actually getting better Mpg though, around 34-37city (compared to the 26-30mpg city i was getting after the short ram intake install); i have a long highway trip tomorrow so ill take note of my mpg and update post again tomorrow night. If you are aware of the name of the toyota link device used to load up the obd2 data onto my pc id love if you could link it so i can purchase one
    PS I only ever drive in maintenance mode (TC off) and use B mode almost every time I stop so that the engine stays running at almost all times, so in light of that, 34-37mpg is astounding
