Has anyone changed out there joyner trooper motor for something else

[Jarrettj88]

I was wondering if there was any easy conversion out they're that someone had done to change it the motor and trans to like maybe a chevy motor or something where parts are easier to come by and cheaper.

A lot things can be done, standard tuning.

Did you say easy? Is there such a thing on a motor and tranny conversion?

I have caught wind of a few members starting a possible swap, but then they die of old age before it's done.

You need to find a fwd car with a really low first gear, I can't think of any, then weld the differential together so they are locked. I think finding a motor the right size with a low first gear is the hardest part.

Keep us posted if you find anything. I will do the swap myself if we find the right set up.

I just joined the form today and I've been looking at engine swaps for my t2 trooper.. I live in Indiana and the Joyner is geared great for the type of riding I do.. But the cherry motor doesn't have no where near enough power..mine is really low on compression too.. I want to stay with same 5 speed tranny.. A friend of mine gave me a d16z6 Honda civic motor.. 125hp stock..

The trooper will carbon up causing low compression. Have you pulled the plugs and put a few ounces of marvel mystery oil in the cylinders overnight? I had low compression on a cylinder, put 2 ounces in it for a few days and it came back. Also you may want to run some in the fuel and oil sometimes. Not sure if your interested in doing so but might be alternative to engine swap. I've also put a turbo on mine, plenty of power.

What are you using for fuel tuner?

I am running a Mallory fuel pressure regulator (PN MAA-4305M) for supercharger and turbo applications from Summit Racing. Just run vacuum to it from the intake manifold. I pipe it in with some fittings from local hardware store. I also have a gauge on the regulator from Summit (PN SUM-800199), dual fuel pumps from parts store running in parallel, they are AIRTEX E2000 pumps, you can cross the E2000 with Carter, Bosch, spectre, etc. I like these pumps because they have a lifetime guarantee and I run in mud and water, so when they fail I can run to the local parts store and grab another. Changed the fuel filter out to a 1997 Chevy Z71 filter, once a gain for easy replacement. Not sure if it was necessary but I removed my fuel cell and had a local weld shop put half inch bungs in the supply and return ports of the cell (I don't have aluminum welding capabilities) and run half inch supply line to pumps. 100 octane LL fuel.

Sorry haven't been on here in awhile.. been really busy with the Joyner..I looked very low compression in every cylinder..I looked around online and found a auto parts online store in China.. they sell all kinds of parts for the Joyner motors..[ sqr472 ].. I ordered everything the I needed.. new rings,gasket set,rod and main bearings,new oil pump. I got everything for about $100 US with shipping..!! I overhaul the motor once I got everything and it still didn't have enough power...!!!!i then ordered a cheap t3 turbo off eBay ..I got it put on and modified the stock header  to mount the turbo..I bought a universal fuel / timing control off eBay . ( it's a piggyback ecu..) still been trying to get that all hooked up and I'm waiting on some an fittings to come in for the oil cooler for the turbo..

[dwaynebradley377]

What kind of piggyback tuner ,I've been using a EJK from dolbeck for about $250

Seems to do the trick but can't control timing .

If your efi remember to defeat the map sensor or else the ecu will shut off fuel when map sees boost 

[Tobie1987]

its universal aem fuel/ ignition controller. Came with software and all for around $300 off eBay. But you have to splice into you harness at the fuel injectors,map sensor, and cam sensor,and 02 sensors.. or buy another adapter harness for another $500..then u plug it into a laptop and use aem software to tune.. I really want to run the aem controller.. but there's a lot to it and instructions only tell you so much and still tryin to figure it all out.. I also think of just buying the ejk dubeck fuel controller you have instead..do you order it from them or silver bullet..?? They told silver bullet version is more suited for a turbo..

[dwaynebradley377]

Yes Silverbullets is the same tuner ,I liked this tuner because it's a 5 min install ,no wire splicing and such 

I belive that with the 6-7 psi I'm running not to worried about retarding timing,

Any ideas on that ?

But if you use that tuner, diode your map sensor and use o2 simulator to fool stock o2 sensor 

 

[Tobie1987]

How much more power did you get with the turbo as far as hill climbing and bottomend power..??

[dwaynebradley377]

completely new machine with turbo now , little bit of hesitation off the line but now keeps up to my friends Wildcat X 1000 throws mud like crazy in 4x4

It was a night and day difference. I don't have any numbers as far as HP and Torque. With my 28" tires on the pavement mine begins to pull the front end when it boosts. The front passenger tire will leave the ground a few inches in 2nd, 3rd, and 4th. Right now I have 30" super ATV intimidators on the buggy that are actually 32" tall. It doesn't pull the tires with those on it but it will go anywhere I want to go with authority, just drive it on the aggressive side.

[Tobie1987]

I'm running 26 inch rip saws..!!! Lol

[dwaynebradley377]

Mine being cvt transmission won't pull that hard ,whats top speed with 5 speed ?
I'm getting 80mph

[Tobie1987]

What year is your Joyner trooper..?? Mines a 09.. before with the low compression i was lucky to see 40mph to 45mph if I was lucky.. with the 5 speed.. don't know yet about the turbo..?? Did u put the cvt in yours..??

[Tobie1987]

The 5 speeds have gear reduction.. very low geared.. granny 1st..  like maybe 10-12 mph in 1st.. I like how it's geared.. for around here.. I trail ride and do a lot of hill climbing.!!!! motor was just way under powered..

[dwaynebradley377]

I have the xy groundpounder 1100 same engine as troopwr but comes as cvt unless you buy the renli 1100 version.

27" big horn 2.0

Turbo with all gauges

Hydraulic e brake

Elka stage 4 shocks 

 

[dwaynebradley377]

Motor was so underpowered for CVT

All of you that have the ejk fuel controller with your turbo.. what's the best settings with a turbo..?? I'm gonna be ordering one soon..

[dwaynebradley377]

I have all settings at 1 except full throttle at 6

But I'm also cvt will make a big difference

Wow.. I would of thought with the turbo you'd want it richer..

[dwaynebradley377]

I'm running a digital af gauge and even pulled plugs all is good .about 12.5 on full throttle .
I would strongly recommend getting a wide and gauge also

It really does take a lot of guess work out of the equation ,you can tune in matter of minutes,I have a hummer on nitrous ,rambler on supercharger and my komodo 1100 on turbo they all have a gauge
