    Building seadoo speedster up to 510 hp

    So I have a seadoo speedster 200 430hp and I'm going to build it up to the newer horse power levels by adding x chargers new props 50 pound injectors and some vteck tunes. I'm also going to be adding some external intercoolers and was wondering if I needed to change the water restricters that are inside of the pump. Right now the restricters are the color yellow,should that be good enough or do you think they need to have a different size one in there.

    Why are you going with 50 lb injectors with a stock x charger?

    50 pound injectors with a vteck tune keeps you from having to go with rrfpr.

    Ok, ok, ok, I'm going to bite , where did you get that information...

    If that was true, you do realize that you could use your ecu with 100 dollar RRFPR's rather than spending 600 dollar a motor for the vtech...
