Hello UTVBoard!
I am new to this site as well as a new onwer of a Joyner Trooper T2. I am very skilled in mechanical knowledge, I love this buggy but am starting to notice some flaws and issues finding parts...
I am located in houston TX and use my Trooper for mud, and we all know how hard on anything mud is!
I am interested in turbocharging my Trooper. I have everything figured out except, fuel management & timing (retarding the timing) what do i need to do as far as fuel management and do i need to pull away some timing? I'm only looking for about 6 PSI But anyone who knows much about boost knows at 0 psi (Atmospheric pressure) you ar pruducing around 14 PSI, add 6 more and you are close to 20 overall... i have always run head studs, cometic head gaskets etc. being how hard it is to find parts for the chery motor its looking like that stuff is not gonna be an option... how dependable is this motor when super or turbo charging? what will be my next week link? i have already ordered the kevlar clutch, what else can i expect to need? by the way i will be running an intercooler... i know its not really needed for only 6 PSI but the kind of riding we do is a lot of lower speeds so an intercooler will help with keeping temps down... big thanks for any help!
Second i have already (on my first ride) had diff issues... the guy i bought it from said both diffs were upgraded but.... the rear diff failed, the 12 bolts that hold the ring gear losened then stripped out then fell out.... I have plenty of experiance setting up ring and pinions and both the ring and pinion gears looked perfect, the spider gears could be better but far from bad... i re tapped the ring gear got heat treated hardened steel bolts and loc-tite sealed it back up and on the trail again.. all of the bearings looked good, im not a big fan of re-using seals but didnt want to search for new ones when these were ok... how do i tell if they were upgraded???
Third The dang starter... wasn't working when i got the buggy but a little looking and figured out the starter motor crosses over to a mitsubishi starter motor and soliniod... new starter installed and i still have the soliniod "clickl" but no starter, enough turns of the key and it engages... sometimes ten to fifteen cycles and sometimes it starts on the first try.. very frustrating! i have not checked the voltage at the starter but being so sparatic i dont think thats the issue. anything you guys know that i dont? anything i should check?
last is there anything that crosses over to the Chery Motor? toyota, mazda, mitsu stc.????
Thanks for any help or advice i am learning a lot about this thing and it is flat AWESOME off road!
look foward to helping with anything i can in the future!
Thanks Josh AKA Swamp Donkey
