    You have to make your own. Honda only sells complete turbos. I've made them from other stock applications and tig weld the mount. HKS Garret IHI etc have new aftermarket but you still have to adapt to fit.

    Make sure you get a 8 PSI bias spring or else the WGS and Waste gate will not function correctly with a stock ECU.

    Honda 2002 F-12X how to check if turbo is good?

    My wastegate was rusted and i fix it and got it back to work now, when i turn on the jetski my turbo is working but there is not too much air pressure for the little house that goes to the wastegate that means that the turbo is bad ?? i disconnected the hose from the wastegate and put it close to my face while accelerating the jetski above 4 rpms and the hair that is comming out to the wastegate is poor ?? any advice thanks.

    put 8 PSI of air pressure and see if the waste gate rod moves 3/8 of an inch.

    yes it does it moves but when i put the water hose to the jetski and rev more than 4000 rpm it doesn't move?

    I'm pretty sure you need resistance on the engine in order to build boost, therefore the waste-gate will not work by just running it on the hose.

    It wont build boost "on the trailer" soo stop doing that!

    Do the "nitro check" on the WGS and also put a gage on the turbo to see what/were the boost is building.

    If the waste gate rod is moving your WG should be working OK. You may have other problems such as the ECM and MAP sensor not communicating, but first do the check I ask and add a gage for more info.

    That's true on the trailer i was not doing anything so i decided to take it to the lake and the turbo started to work at 4.8 rpms i think my wastegate actuator is bad because turbo should kick at 4 rpm and also i don't get 6000 rpms and spark plugs are new and filter is new too so it has to be the wastegate actuator not not fully opening, can i replaced with this one ....
    Cracking pressure is at 3 PSI; fully opened at 7 PSI ????

    No, You need 7-8 psi cracking pressure for a stock ski. Reason is the WGS and WG are both tuned circuit's that need the work together.

    A large difference between the cracking PSI and total boost is very hard to control. Best to keep them as close as possible.

    I'm giving you stock PSI requirements here. 7-8PSI cracking, 12-13PSI total

    If the wastegate actuator is a little harder than 8 PSI would it work ?
