    Turbosmart FPR rebuild kit?

    Where can I get this? OR
    which FPR should I use to replace the TS FPR 800?

    Thanks!

    The Turbosmarts have been seen to not rise 1:1 and sometimes get stuck. I would get a aeromotive from Summit Racing

    O.K, here it goes....

    Would this cause my ski to stick at 7300 rpm from 1/2 throttle on up @ 10psi boost?
    Normal rpm is 8260 with a 15/23 4 blade with a 2rude, bosch 50lb inj's @ 14.2+ boost, I was trying a 15/20 4B just to get the R's up but nope!
    1/2 throttle 7300 & smooth, the rest of the throttle is just dead pulln no engine miss or stumbling either. At this 7300 rpm the afr was 10.1.
    The base is set at 52 psi key in, 48 at idle & 58 psi at 7300 rpm with 10 psi boost on stock class rotax racing 8300 ecu...
    Ran an 8800 rotax ecu & bumped the psi to 60 base and I would see 7880 - 8020 rpm @ 11.2 boost with the same setup swapped out on the water within 5 minutes, I should be seeing 8500+ rpm with this 15/20 on that 8800 ecu. Inj's are clean but the guts in the FPR were rusted & had salt water corrosion on the spring & the diaphram looked pretty weak. The increase in boost & rpm rule out an intake mani leak..
    What gives?
