    06 stx 12f swap to 15f???

    Hi guys i bought a really clean 06 stx 12f with everything minus the motor. I have the intake and exhaust manifold and all electroincs for the 12f motor. Now i have a choice in motors either the stock 12f or 15f and its only $200 diffrence in price. Wat i wanted to know if anyone could help is it an ez drop in if i wanted to go for th 15f motor over the 12f? Any help would be great.

    It will drop in you will need a new pump and new ecu to match the 15f, if you have the 15f intake manifold and throttle body then it will go in fine, you can not run the 12f intake manifold or throttle body.

    Didnt want to start a new thread since I have a similar question. I have a nice running 12f with everything (trashed body) and a clean body but broken motor 15f. What would need to change if I make the swap of a 12f into a 15f hull?

    Thanks.

    The only difference is ecu and prop.
    Even harnesses are same.

    How about throttle body?

    Throttle bodies appear to be same. Same sensor/control plugs, etc. I can't say I've swapped them though. Intake manifold is different however. Throttle body mounts, plug ins, cable landing, all same.
    I have both if anyone needs one.
