  1. Hello Gator owners,

    I'm here hoping that you all can give me some insight and advice into turboing my 2012 polaris ranger..... now before everyone goes on defence, just let me say I've been owning john deeres all my life and all of our farm equipment is deere, except our UTVS....not because polaris is better, but for other reasons entirely, which I will explain if it interests anyone.... The real reason I'm here is because I know that many of you are diesel owners who have the little cousin to the yanmar that's in my Diesel Ranger. I think the deere's engine is an 855cc yanmar, and the one in the polaris is the minimax 904cc yanmar. very close in size and most likely very close in HP. My ranger is in need of a HP boost. The diesel gets around ok, but with a cab on it, it's really shut down my top speed and hurt my acceleration, which wasn't very good to begin with.

    I'm serching for a good turbo to put on this engine. PPE sells a turbo kit for $2600 for my ranger, but is way overpriced for me. I'm thinking I'd like to do this swap for $1000 or less. I'm an EX caterpillar mechanic, so hooking it up won't be the issue, but I'm gonna need a correct sized turbo, and some insight.... I figure there's gotta be alot of you 855D guys that feel the same way I do about the little yanmars in these things... great engines, but need a little bump.

    Anything you guys could help me out with on this as far as good turbo's to use, where to get them, and maybe some of you would even have somthing for sale? It would really be appreciated!

    Adam​

Yanmar Turbo

We just did one on an 855d, it improved power very nicely, the kit came through weidmann bros. dist out of California it retailed for 1995.00 and we billed 4 hours time.

the machine we put it on was loaded down with a fire tank/pump system so it is not a race machine but helped with low end greatly.

Really cool! I like the info you can see on a dyno. No need to compete with RZRs in my neighborhood (only Gators, Mules and RTVs within 10 miles of my farm ;)) but I always have an itch for more power too.

You might find a Therma King unit and see if that turbo would work. Can't remember right off the brand engine thats in my shop, but I wouldn't think there would be that much of a difference in size. Mine is a 4cylinder, but its not much bigger than than Yanmar at all.
