Upgrade Question / Leaky Intercooler Edit: All Fixed Now
I have a 12' RXP-X 260, which I have always had problems with a sticky throttle body. However, after doing a lot of reading it does seem to be a bit of a common problem on these ski's as the intercooler leaks. My throttle body has now completely locked up, so its looking like ether a new one or a refurbished one (My warranty ran out in May). So the ski is throwing all sorts of errors.
With all the above in mind, as I need a new intercooler now as well I am planning the following mods:
RIVA Sea-Doo RXP-X 260 Power Filter Kit
RIVA Sea-Doo RXP-X/RXT-X 260 Intercooler Tubing Upgrade Kit
RIVA Blow Off Valve Block-off Kit
RIVA Sea-Doo 'GEN-3' Power Cooler Core
RIVA Sea-Doo RXT-X 260/iS/aS and RXP-X 260 Free Flow Exhaust Kit
RIVA RXP-X/RXT-X 260 Pro-Series Sponsons
RIVA 07 and older Rising Rate Fuel Pressure Regulator
RIVA Catch Can Kit, SD RXP RXT GTX 4-TEC
Solas 15/19R - Possible change?
I currently have the following installed:
R&D Aquavein Intake Grate for RXP-X 260
What are the opinions on the following mods?
Also I do plan to add a ECU at some point, is the Motec M130 best choice for the above mods? Also who / where do the maps come from with the ECU? Also is there support in the UK for them?

motec it always the best ecu choice
but you don't need it on a stock ski
vtec will do everything you need (save us$2500)
also add upgraded valve spring retainers at minimum
there is big HP gains past 8000 rpm

Nice list! If you leave the stock ECU untouched for now it will keep the performance down big time. Personally I would start with flashing the ECU with V-tech 8375 AGR tune (unless you are ready to get Motec now, not in some distant future)
BTW, how did you ended up with SRX impeller? Make sure your next prop will be SRZ type.
Your pitch is high for stock ski,
what max rpm's are you getting now?

As I am doing all the work over the winter period in the UK, is the 15/19R impeller the best to go with for overall performance and top speed. Id guess my overall goal would be to hit 75 / 80 and id be happy.
I'm normally of the opinion that if I buy something once, I'd like to make sure its the correct item from day one other wise i tend to waste money trying other items out etc...
Is there anything else I can add to the list which would add to the performance? or items which are worth changing?
Also what is the support like for the Motec ECU? Even in the UK?

If your going to rev to 8800 rpms then you should also change the flywheel bolts to ARP from what I have been reading.

Well a few months on and a few large boxes from Jerry, the RXP is now up and running again.
When I pulled the stock intercooler and TB, this is how I found them. The TB had locked solid, I had the intercooler pressure tested and well it didn't hold any pressure.
So a few month on and a number of long weekends its now up and running and also replacing a number of sensors.
I've also installed a filer, as i mostly ride in salt water and help protect my new inter cooler. The whole ski seems, to be much more lively.
I do have one question, Ive bought a V-TECH Map Tuner and License to tie me over until I can get the ET68-140 and a Motec M1 but its saying the Maptune is locked please connect to the PC. I have emailed Michael but I dont have a reply yet? Is this normal?
Once I've finished installing the rest of the bits and I still have a few more to go, I'll start a build thread.

It might take them a couple days but they will eventually answer. There is a list of people you can email, that has worked for me in the past. Found here --> http://www.greenhulk.net/forums/showthread.php?t=207736
