  • LX9 swap - 3400 injectors or 3.4 dohc injectors?

    I have 2 options that will work with my OBD I ecm and I see pros/cons with both so help me decide.
    I realize either option will require tuning.

    Option 1: 3400 injectors (not sure what year, can prolly find out if that info is important)
    Pros: Correct Spray Pattern
    Adqequately Sized
    Cons: Unknown Condition, they are used and I have never run them on a motor (ohm out OK)

    Option 2: 1997 3.4 DOHC Injectors
    Pros: I know they are good as I ran them on my 3.4 dohc
    Aqeduately Sized
    Cons: Spray pattern is not correct for a pushrod. Will this impact the fuel efficiency?
    Will fuel hit the port walls and condense since it is not a straight shot at the valve?
    Will the spray pattern have any impact on how smooth the motor idles?

    I know others have used 3.4 DOHC injectors on pushrod motors before with good results. I want the LX9 to be as fuel efficient as it can and make good low end torque.

    I'm currently leaning towards the DOHC injectors only because I know that they function correctly.

    Last thought, will either of the sets be easier to get the tuning right?
