    Can 04 4tec 155hp be transformed into S/C 215hp motor?

    Can it be done? Can you change a 04 4tec 155hp motor into a S/C 215hp? I know the pistons have a different part# would they need to be changed also? Has anybody done this? Thanks

    there are a few threads on this, you will have to search. pistons are different, they are not forged like the SC motors

    It can be done but in my opninion it is soo much work that it's not worth it. You are better off buying a 215 motor and selling yours. Another option is to go turbo instead. I'm not familiar with the ECU of the 155 but if you change out the pistons, get a riva ecu and proper injectors to run it and add a turbo you will spend a little more money but you won't have to worry about washers any longer and will love the performance.

    so pistons would need changed? I have most of the parts...ECU, injectors, inter cooler, would not need to buy alot. I was thinking about buy this Sportster boat that is 155hp and would want to change it to 215hp motor.

    I have looked for the thread about this but haven't found it yet. I guess need to look a little more.

    Different fuel pump.
    The double row gear will be different as well.
    cam is also different.
    not sure about valves and springs?
