green wheel, what else do i need??

[lextoy]

right now i got my 2003 GTX SC
with
R&D air intake
GH waterbox
no opas
filled plate holes
pump wedge
upgraded pump with a 12/20 impeller, still the GTX SC size wear ring...

i am getting 63 mph and 7100 rpm.
i know i should be tuned to 7600 rpm, i can either bend the impeller, or get more HP...
if i get my SCer rebuilt to 08 specs, and get a greenwheel also, what else do i need to do to the engine to make it run, upgrade injectors? upgrade fuel pump?? anything??
i want one last simple upgrade to make more power, but i dont want to have to deal with a cascade of other parts upgrades...
anything simple i can do to get my impeller spinning up to 7600?

500 RPM's is a lot of tweeking, send it back to whom ever you bought it from and have it re-pitched to make up your missing 500RPM.. Having your prop repitched professionally will be better in the long run

Amen...its the pitch in the prop. I had the same problem....got a local jetski shop to research my issue and resolved it by putting in the correct pitch impeller....and whoola...instant 800 rpms...and instant 5mph!

ttt,cmon guys, can i just put a greenwheel in my sc, and do nothing else?
i know with cast engine parts i am limited...

I believe you'll have to upgrade to the RXP 58 psi fuel pressure regulator. Maybe someone has one laying around after installing the RRFPR..

Lex, i think you will be perfectly fine with the green charger and stock injectors and your modifications. No regulator needed. The GTX SC supercharger has a 17 tooth gear and doesn't spin to the same boost levels a RXP/T would.
