Hello everyone. I was glad to find your forum. I guess you are the ones who can help me to answer my question. I am planning to rebuild my existing buggy and I have chosen 4x4 Justy, as sorry to say, the donor car. The problem is the engine has to go to the back, as far as I understand my main problem is gears, so my question is. Does anyone has any experience of moving the engine to the back, what is the solution with the gearbox, which gearbox is easier to adapt manual or CVT. What other complications I might have? Thank you:)!

You should look up the Crowe Justy in New Zealand. They mounted an EJ motor in the back of the Justy and made it RWD using the FWD L running gear flipped. It is a badass little machine Also a fellow member on RS25 has thoughts of throwing an EG33 in the back of one at some point -Jamie

Good news, I see that I am not the only one with the crazy idea. Thank you for the link, I will look for the guys, see what and how they did it. I have found couple of more links, when people trying to put Justies engine to the rear, but mostly it is just talks, plus they only plan to keep it rear wheel drive and I need it to stay 4x4!

Keeping it 4x4 is going to be the tricky part, not un-doable, but tricky and probably costly(unless you own your own machine shop ) I am planning on making the Justy RWD when I do my MR swap down the road. EJ18 MR Justy should be plenty fun, lol.

AFAIK, the Crowe Justy did not have the driveline flipped. It was mounted as is, with the motor as a "mid mount" in front of the rear axles.
Cool car and I think still runs once in a while.

Well, unfortunately I do not have machine shop, but it still should be cheaper then buying Polaris Rzr or any other desent buggy. Joyner in Europe can be bought for around 600€, the buggy I have and rzr is what 10000€ or so:) With the 4x4 I imagine, that when the engine goes to the rear it powers the rear wheels and front wheels are powered on demand by pressing the button on the gear knob. Well I will keep reading, I am afraid I am too optimistic about this:)

The transverse transmission used in the Justy does not allow you to flip the "ring and pinion" so you have "forward gears" going backwards. So if you turn the driveline around, you will have one forward gear (true reverse) and 5 reverse gears...
The only way to use the Justy driveline with the motor in the back would be to put the motor ahead of the rear axle, ie facing forward, then build a transfer case that bolts to the "tail shaft" and route a drive shaft under the motor, and up to "rear diff" now upside down facing backards (so the wheels turn the right way).
You're talking major engineering...

If you don't have access to a machine shop, it would probably more $ then buying a new buggy (if you wanted it to actually work...)

Well, this is a piece of good information, I guess I should consider other choices and check other gearboxes:( I have found this guys www.subarugears.com/Builds/builds.html, they convert gearboxes, but justys is not in their list and they are expensive:( What about Cvt transmision, same case? No possibility to invert? My other options Fiat Uno 4x4, Suzuki Jimny, Lada Niva:) I will start investigating them.

Yes, most subies are a longitudinal engine driveline layout, therefore they use a ring and pinion drive for both the front and rear diffs. Transverse transmissions use two standard gears to drive the diff... you can't flip them around and have them change direction.
If you could get the motor to run backwards you'd be golden...
