    I've been finding small differences between the engines which no one seems to mention.

    Piston Compression Height
    • VVT-i 1.268"
    • Non VVT-i 1.256"
    I've also found that the Non VVT-i engines use the bigger valves that the 1ZZFED uses:

    Stock rail can be used and it doesnt matter if the car is an auto or manual the 1zz and 2zz both use Denso Type E injectors.1zz injectors flow around 260cc and I'm pretty sure 2zz are around 310-330cc
