    I think you got it. Those two items are what I know as well.
    Hard to believe that translates into 40 ponies.

    I know you can convert a 110 to a 150.... but let the pros answer this one.

    The MSX 150 engine is rated about 135HP.
    I am not sure what the actual HP rating on the MSX 110 motor is

    There were some other differences, posted in an older thread.
    Blow-off valve?

    The differences are:



    ECU calibration:
    • Boost map:
      • MSX110 tops at 11psi @ 7,000rpm , then boost decreases gradually between 7,000rpm to 7,500rpm.
      • MSX150 tops at 14.5psi @ 7,250rpm, then boost decreases gradually between 7,250rpm to 7,500rpm, then decreases more aggressively between 7,500rpm to 8,000rpm.
    • Fuel maps: MSX110 fuel calibration is richer across the entire 4,000rpm to 7,500rpm range. Low speed fuel calibration is fairly similar for both skis.
    • Air temperature compensation maps: calibration is different from one ski to the other. This has to do with the different efficiency rating of both intercoolers.
    • Pedal Position versus load reference values: throttle flipper to ETB movement is calibrated differently from one ski to the other. There is no difference from 70% throttle to 100% (wot) on the MSX110. The MSX150 utilizes the remaining 30% throttle flipper movement (however, not fully linear to ETB movement).
    Impeller:
    • The MSX110 has a low cost steel impeller optimized for a 7,000rpm @ approx. 10psi boost.
    • The MSX150 has a Skat Trak SS impeller optimized for approx. 7,300 @ 14psi boost.
    Blow off valve:
    • The MSX110 does not have a Blow off valve (BOV).
    • The MSX150 has a Blow Off Valve which is a genuine Bosch 25mm rated @ +16psi. This BOV is similar to oem automotive on SAAB, Audi, VW & older Porsche 924.
    • The aluminum intake tube between the intercooler to the ETB is different on both skis because it is where the BOV is connected.
    Intercooler:
    • The MSX110 has a tube based copper, low efficiency, intercooler.
    • The MSX150 has a tube & fin based aluminum, high efficiency, intercooler.

    Guess I should have been more clear. I have a msx 110 with a geeked up engine due to cooler. Just bought a msx 150 same year. Would rather have a 110. Can't I just leave the core on and change the ecm back to the 110 and be ok?

    Ok... sorry for the long & boring answer above.

    To your question: Yes.

    However, put your 110 impeller with the 110 ECU.... otherwise there will not be sufficient boost at mid-range and the ski will feel sluggish.

    Thanks so Much, unfortunatly I have to take the engine out of the 150 and install it into the 110.. Boy thats so much fun, let me tell you..

    Desperado, I had had 3 of these aprt recently. All had oil in the exhaust have you ever ran into this?

    Well, I answered my own question.. I sure do wish someone would make a decent turbo for one of these crap boxes.. Do parts for these sell well? I may be parting both out..
