    as long as I know, you will need RRFPR, AFR, 1000cc fuel injector, high vol fuel pump. and i think you are good to go

    No internals? Or possibly valve train upgrade? Have the upgrade already just havnt installed not really needing it with my setup that I have.. Are 1000cc injectors needed really the thought of buying them is crazy prob the most outrageously priced item for a ski..

    No 1000cc injectors are not needed, I have build alot of ski's with H1 setup. On my SHO with a H1 and a R2 reflash i am running 660cc rated injectors at 43 psi. with rising rate hooked up, stock springs, and internals at 8900 rpm running 87mph. plus with a killer holeshot. Oh and the ski has 135 hours on it 95 of them hours are with the H1 wheel.

    correct me if I am wrong please. I know that the ECU controls how much fuel is needed, therefore, it opens and closes the injectors depending on that, so if you have the 1000cc and the 660cc and the ECU wants lets say 100cc, it will open them BOTH for the same quantity. what I want to say is that getting the 1000cc is cheaper and at the same time it will do the same job as the 660cc.

    i think they both are the same. as for me i am using 160mm with 13/22 with TBM cone, and i must say i am really happy with this setting, cavitation is 10-15% or 2 on a scale from 1 to 10,

    You can not run 1000cc injectors with a R2 or R3 yes the pulse from the computer will be the same for both injectors but the volume of fuel that the 1000cc will put out will be to much it will be so rich especially at idle that you can not lower the fuel pressure enough to over come it. I think the only reflash that r&d makes to run with 1000cc injectors is the R12 Hope this info helps. Thank you, Jim
