Hello from Kansas USA, this is my Justy. Its been a very reliable car and great for commutes to work. I found it on craigslist, a guy in Nebraska was clearing out his field of cars that had accumulated over the years, it was rough but I've been pouring TLC into the little guy and he's come a long way. Wouldn't run smooth and refused to go into gear so after lurking on this board for a while and discovering the hopeless complexity of the Hitachi carb I decided to do the weber carb swap, and changed out the clutch (the original carb had a "gasket" someone had carved from a tire and was leaking vacuum so maybe the original carb was still good). Those two things plus some new drive axles and all major issues were solved. It's still running strong but considering a rebuild for two reasons, one is that it has weak oil pressure, could either be oil pump or cam bearings, idk but reason number two is that the parts guy at the Subaru dealership says Subaru will stop carrying back stock OEM replacement parts soon, so a rebuild would probably be best sooner while parts are still available. Parts are already getting difficult to find so its a bit of a race against time. My goal for this car is to get it back to factory perfect as much as possible, with the rebuild I hope to accomplish greater horsepower, reliability, and increased fuel economy. Now I know what your thinking ("you can have two of the three") but I plan to keep it naturally aspirated, so we're talking modest gains, but gains nonetheless between the new carb and it having to be bored out .20 over because that's the only parts kit I can find. So some questions for the board.
Weber dgev 32/30? (ill have to check the exact model name but its the one with the electric choke) owners: What size jets are you using? I'm looking to run on the lean side to increase economy and reduce oil wash in the cylinders for extended service life.
Is there high performance bearings out there that are better than factory?
Should I get new connecting rods and pistons for the rebuild or can I reuse the old assuming clearances check out?
Is there a strong high performance racing clutch out there for justy?
I plan on having the motor balanced to minimize the violent nature of the three cylinder, is there anything regarding the "thumper" counterweight thing that I could do to enhance this?
This is all the questions I have at the moment, trying to cover all my bases because it'll probably be the last time it will be possible to rebuild.
But for today it gets me to work, it highway driving so the high RPM's keep the oil pressure up for most of the drive, always starts, more reliably than some newer cars, always gets me there, I love this car, and it may love me back seeing as how it seems to run on love.
