    4 TEC 155 mods?

    Hi, just looking at what I could do to my 07 GTX 155. I saw the R&D performer kit, and it looks OK but I am wondering how much overall speed I will gain, and if there are any other better options.

    One newbie question... is there any way I can add an intercooler and SC to it?

    Suggestions would be greatly appreciated and this forum is awesome.

    Before i mod a 155hp 4-tech id much rather save up and trade it in for a 215hp unit theres tons of potential in them and are at good prices these days , besides moding your 155hp 4tech to just the stock performance of a 215hp will probably cost you thousands.

    Personal Experience... Definitly look into upgranding your boat before considering to mod the 155. Search the classifieds here and on ebay for some used 215 hp boats. Be patient and you will find a good deal. --jpe

    The cast pistons in the 155hp just aren't up to handling a lot of performance modifications; can't go much farther than free-flow intake. Best performance mod you could do is trade it for a RXT-X.

    THanks guys,

    Unfortunately buying an RXT -X or upgrading is just not an option at the moment so I thought I would see if there are any other easy ways to get a few mph. Any other suggestions would be helpful.

    Thanks,
