Hey all, I just picked up a 93 Justy four door, 4wd ecvt. I'm planning a pretty serious project and will need your help.
I want to create a vehicle that is more efficient and much more capable then anything available commercially at a fraction of the cost.
My end goal is to disconnect the rear axle from the rest of the drive train, and hook up a motor/generator to it with enough battery power for a day of city driving. This will allow me complete battery in the city, regen braking, and optional gas engine backup for exhauseted batts/highway. Also, I hope to be able to rig up a system to allow use of combined gas and electric four wheel drive to help move about in Canadian winters. (Not sure if this is feasible)
But first, I want to modify the cvt. This thing is in no way profiled for fuel efficiency. The pick up available from this little engine even with four wheel drive on is amazing. I need any information anyone can give me on the transmission, especially the control system. I assume it's just a voltage system, and if that's the case it should be possible to hijack and manually control, or even and add a third transmission profile.
Is there an easy to change final gear on these transmissions? Ideally i'm looking to get my Justy's tach down into the mid thousands at 90km. I'm not sure what the tallest ratio available from this transmission is, but I'm pretty sure it can't be that tall. Does anyone know the max and min ratios?
And I really need the manufacturer service manuals. Does anyone have these or know where they're available? Physical or digital copies would be just fine.
I think I've begged enough for one evening, ;D, if you think you have something that might help me, please let me know. Glad I was able to find this forum guys,
Robert

I want to create a vehicle that is more efficient and much more capable then anything available commercially at a fraction of the cost. ......regen braking...... But first, I want to modify the cvt. This thing is in no way profiled for fuel efficiency. Robert, I disapprove of this idea. - #1 I don't think you are going to improve on the efficiency of a Justy at a fraction of the cost...of anything.
- #2 Good luck with regenerative braking. That is very advanced technology and I suggest you just purchase a used Toyota in that case.
- #3 Do you mean to say that the ECVT is a terrible transmission for fuel economy?!? If so, you sir are misinformed. Although the first of its kind, the Subaru ECVT gets a bad rap due to it's unreliability (deservedly), it is however excellent at what it was designed to do and that is to get great mileage without hurting the performance of the vehicle. The ECVT Justy was perhaps the only car in North America that had identical 0-60 times and fuel consumption as the manual-transmission version of the car.
I am annoyed by electric car bozos, always wanting to chop up a Porsche 914, Chevrolet Corvair, Renault 5, F.I.A.T. 850, Yugo/Zastava, or Subaru Justy. Why don't you guys use talent and technology to showcase your creations rather than relying on odd cars to get attention? Please, leave increasingly rare classics to people that want to preserve them. Go cut up a Ford Ranger, Honda Civic 4X4, Eagle Summit, Toyota Corolla 4X4... they are actually much much better candidates for your project because parts are easier to get, the vehicles are tougher, the wheelbases are longer and the engine bays are larger.

Email sent with my thoughts. Don't want to kill a thread with a book.
I don't mean to be rude SeattleJusty. Yes, the Subaru Justy is increasingly rare but I wouldn't go so far as to say its a "classic". I agree it has some features not seen yet by many or any other production car like: ECVT, balance shaft, transverse engine and trans arrnagement with 4wd, composite valve cover, most advanced carb I've ever seen on a production car, push button 4wd with no extra reduction). This is: however, nothing more than an economy hatch from Subaru with the only things really setting it apart from the suzuki swift, honda civic, toyota tercel, etc is the fact that it was available 4wd and with the ECVT transmission. I have owned 5 subaru justys (2 are in excellent shape, one field car, 2 ripped for parts and scrapped). Mileage is similar to civic, tercel, 323, not better than sohc swift 3 and 4 cyl, but with the 4wd I agree it is very impressive. No collector car can be purchased 5 for under $1000 total. Don't just throw words like bozo around or someone may end up turning it around on you. Anyone on this forum putting any extra money or time into the subaru justy is likely insane. I know I am. Lets just accept the fact this car has a way of making people love it and go with it.
Let's see some more views on this post.

Lets just accept the fact this car has a way of making people love it and go with it. Let's see some more views on this post. Sir, almost everything you said in your rebuttal is opinion (your opinion) only and I can see that you didn't truly read what I said. I read what you said, three times in fact, before I wrote what I did. I mentioned the 4X4 Civic, the 4X4 Corolla and the 4X4 Summit. Balance shaft? Those are common actually. Transverse powertrain with 4WD? All of the vehicles I mention in my original post fit the bill as do most modern AWD cars. Composite valve cover? You mentioned that?! You are impressed by a plastic valve cover? Sir, what makes a car a classic is the car having a devoted following. When I was in highschool a Porsche 914 cost about $1000. Now they change hands for $3000-8000 regularly and are considered classics by most if not for their beauty and rarity then for their reputation as the fastest way around a racetrack in Stuttgart's finest until the advent of the 986/987 (which I had the pleasure of driving a few weeks ago). I would love to hear some evidence, facts, intelligence from you. Address me line for line like I address you and every other contributor. Come correct.

I do stand by my words however as the spirit of the dialogue holds water. I won't hold my head in shame over a semantic. OK, back to the discussion

When people like myself and others mod the justy you get affened because it a classic?! Jesus you need to get out more! Or get a better job and collect Justys so nobody can have them. Your like a spolied toddler! "if i cant have em nobody can, and dont touch em big jerk!"

seattlejusty, I think you should stop looking down on everyone like you know everything. drroboto: good luck with the project. You wont know if it's more efficiency unless you try

drroboto/Robert, Any progress (even on the brainstorm side of things) with the rear drive hybrid idea?! I have pondered and discussed this a bit myself for a time! As for ECVT fuel economy and performance (the innovative engineering was based primarily on those two factors)... if you had to go with an automatic in the late 80's early 90's it was definitely the way to go. See the 'one hand and leg tied behind back' Subaru 'drag race' commercial here: www.performancecar.co.nz/Members/Andrew/my-videos/subaru-justy-ecvtKeep us posted!,
