Care to elaborate on those big price quotes? Theres no way it will cost 5k to make a pro handle as well as a axys. Same crappy shocks, same stance front end, same skis etc. Not saying the axys isn't better, cause there is no doubt it is, but 5k is quite an exaggeration. And as far as the turbo goes it depends on how far you want to take it. Lots of good used kits laying around, and as I stated before good end of season deals. Can be done for much less than 5k if wanted just depends on what else a guy wants to put with it. Resale values are certainly something to consider as well.
Skinz Airloc Boards -1500$
Skinz Front end and floats 2300$
Floats for rear - 1500$
You are missing one big thing. The Axys GAINS RIDE HEIGHT! The only way you are going to gain that is with the parts I have listed. I will say it again, and again, the "snowmobility" of this set up is amazing. Other than buying the Skinz parts, the only way to get it is buy a new Axys.
Ok.. just a few words of wisdom, that I have learned the hard way. A sled that handles is better than a sled that just makes gobbs of power. Once the Axys hits the snow, you will find out, stock vs stock chasis. The Axys will walk through the deep snow better or comparable to a turbo Pro.
Lets add it up once.
1.) your going to go buy a new carry over 9000$
2.) turbo kit. sorry, if you buy a used kit, you better know what you are doing or go through it with a fine tooth comb, or it will leave you at the trailer. BTW, I have rode and built turbos for almost 20 years. This is a $7000-8000 bill all day long, if you want to do it right. That's even if you find a nice used kit.
3.) Suspension. If your going to do a turbo, you better do the suspension. Arc, coupled skid, shocks. Turbo is lipstick on a pig if you don't have a good suspension.
So after you spend all this money, first time you pull the sled out of the trailer it will be worth 8-10,000. Financially, it just doesn't make sense.
