Dylan, Depending on what year GTX you have, to do it correctly, for starters you`ll need:
Rotax 58 psi fuel pressure reg
RXP/RXT ecu
Knock sensor update/piggy back harness
215 SC drive gears set (Rotax)
stock intake manifold with stock IC- or- aftermarket IC.
you would also want to:
upgrade the exhaust system
either go to a 12\20 solas 155 prop-or- change out the wear ring to the RXP/RXT 159mm size and have a few more choices in props(impellers)
while you at it, change out the stock SC impeller to a Riva or green wheel, metal washers with the new improved ceramic bearings...
By the time you add all of this expense up and the necessary time involved it would make a whole lot more sense to trade in the GTX for a RXP or RXT...

Its an 05... I was going to put on a stage 1 kit, 58 psi fuel regulator, free flow exhaust kit, valvetrain upgrade kit, and riva thermostat kit... How much is a ecu and a stock intercooler?

if your going to do the valve train upgrade, IMHO don`t even waste any of your time with the smaller prop (155) rebuild the stock pump with larger wear ring and prop to benefit from the higher RPM`s and more juice! assuming that you have a GTX SC and not the limited 215...

Don't forget that you will need forged pistons. The 185-hp engines have cast pistons and are definately a weak item when doing mods... Ron

I think the cam is also diffrent in 185hp engines you might need to upgrade to a 215hp cam.

you'll spend ALOT of $$(and time)converting it to a 215. I wanted to do the same to my last ski(03 GTXSC)...finally said screw it and left well enough alone.
I'd just put a stage 2 kit on it and enjoy
