    Great pictures! There sure is a lot more work to fit a turbo to a jet ski than to a motorcycle or car.

    I can see the size difference in the throttles, quite significant. I didn't know that the original setup was also e-throttle, so that clears things up.

    in fact there is less work

    i'm not new in jet ski , i have work with rius racing in 2009 , i'm from guadeloupe where is the karujet. i have done an ultra 250 turbo and now i help a friend on a ultra 300 turbo , it's how i find this throttle.

    today i start to work on the intak manifold . i want to move the throttle at the back of the engine . will simplify the tube routing . so cut and weld the stock intake . not finish for now just some mockup .
