    FXHO vs. VX110 engines, what all is different?

    I've been doing some research, because i love tinkering with engines, i have a vx110 and have been modding it a little but its never enough.... intake, modified intake manifold, straight exhaust with "custom" water box, r&d intake grate, and solas 18/22 impeller, it keeps up just fine with a gti 155 but i always want more


    going through the parts books and specs, the two engines have the same block, crank, rods, pistons, head and gasket, even the cams seem to be the same

    the only obvious difference is the intake manifold/TBI systems and exhaust manifolds, and of corse the electronics, with 30* timing on the vx and 31* on the fx, and the 110hp to 160hp ratings

    the strang thing is the compression ratio specs, the vx rating is 11.4.1 and the fx is 11.9.1.... what am i missing here?

    the basic reason for the questions is i was wondering about gathering parts to convert the vx to an fx, i know theres few things needed like the throttle boddy assembly, exhaust, ecu, harness, ect

    This has been discussed many, many times. Do not waste you money. Sell the VX and buy an FX.

    Come on now, thats got be the worst responce ever, the question is what, if anything, is different?

    It's been "discussed" but has it ever been done? And a waist of money to me would be selling a paid off ski and spending thousand more on another one that would have the same results... the parts are only a couple 100 used, and having a slightly lighter hull with more hp would be nice too

    If you have the speed bug, you will never be satisfied with a VX, I promise.

    Anyway, I based my response on your last sentence, which summarized your entire post and your motive. No sense in feeding you info that will mislead you IMO. Bottom line, the VX is a basic rec. ski and is not a desirable platform to throw modifications into. I apologize if that doesn't sound sweet and all but the truth is the truth. If you want to build a Yamaha ski that will yield results when modding, at least start with an FX-HO. People that know these skis and are willing to be truthful with other members will save unknowing people lots of wasted time and money. How many fast, modified VX110's are there on the water? If there is one or two, they are in the shadows. I'm not even sure you can buy parts to mod a VX. The GH store only lists a few parts for the VX and they are not even categorized.

    Not saying it isn't a great ski (I have pair of '08 VX110's), just not something that most people spend money modding. They just........ride them. Even if you built a 200hp VX, it is still a VX hull and maintains all the entry level characteristics of the VX. The FX hull is much better suited for your needs than a VX just based on what you posted.

    The VXR has a Nano, 1.8L, boarding step, etc. The VX110 is 1052 and built for simple, basic rec. ski purposes and overall fuel economy.

    what chris is trying to explain to you is simple, you can throw a bunch of parts to the vx's and fx's ho's and neither of them will go anywhere , if you really want to speed up the process , the perfect idea will be a fx sho.

    the vx's are the perfect ski to leave alone and ride the crap out of it , they simple do not break as often as the sho platform , the fx ho is the big brother very good fuel but no speed.

    and here we go again.... is it that hard to answer a question that is asked? a long paragraph explaining you opinions on a different subject is really not nessessary

    Sounds like you have tunnel vision and you cannot convert a VX to an FX because the hulls are not the same at all. Anyway, take care and good luck.

    I owned a 2011 VX. After doing an exhaust mod, ribbon delete and not seeing any gains worth mentioning...I traded in on a FZS and never looked back.
