    I was just going to get an o-ring set and the Pete dealership ran the part number and told me not to stick it back in, so he was kind enough to sell me the proper injector

    Orings will be the same. If the engine has a full set of those injectors it could be a acert converted.

    Sorry to bring this up but I’m trying to find out what’s the maximum I can push an engine I just bought
    The serial number is 6nz74066
    Ar222-9500
    It’s a 435 hp but max rating 625hp can anyone explain me that part. Will it be safe to push it to 550hp kind of lost in that part thanks in advance

    You can flash to a 550 brakesaver file and do just fine without changing hard parts.

    My 6nz00636 was manufactured 12/99. I think the 5th didgit should be a zero.
