    GTR and RXPX engine differences?

    Obviously one has 230HP and the other 300HP. But being they are both supercharged 1630 engines. Is it just a tune difference or more? Can you easily mod a GTR and turn it into a 300?

    Someone correct me if i'm wrong - the way seadoo makes more power these days is larger SC / more boost. Tuning is tweaked to compensate.

    Would need to change cam, supercharger, flywheel. Plus tuning issues.
    And probably other crap you won't figure out til you're balls deep in it.
