Hey there everyone. I'm considering buying a subie for a project car, and I DO mean a project.

I need to know how the transmissions and the 4wd systems work. As I currently understand it, the low range for 4wd is built into the transmission. Is that correct? How is the power split from front to rear?

These are very basic questions, but don't be afraid to be technical about the answers. I am currently building a 1969 Toyota Land Cruiser wagon(FJ-55) that has 6" lift, 35" tires, swapped in motor/drivetrain from a new model, and a welded rear differential. Weber carb, header, homebuilt exhaust, etc. No newbie to tech :D

Thanks folks!

EDIT: Also I'd like to know the width of the wheel mounting surfaces.

If there is a website that thas all this info, I'm all ears :)

Technically speaking, subaru's don't have just a transmission - it's actually the transmission, front diff, and 4WD transfer case, all in one unit. Power split is mechanically locked at 50/50 for all the manual D/R tranny's.

What is this project?

Well its a bit oddball, might be sacrilege to subie guys. I want to put in an actual 4wd tranfer case out of a truck, behind the normal subaru transmission. This done with a short driveline between the tranny/transfer case. Then, solid axles replacing the independant front/rear, with leaf springs.

I'm not even sure it can be done on a subaru. Its either that or an old Toyota corolla wagon, before they went front wheel drive. Just trying to research options still.

Thanks!

This is Unhatched's site for what it's worth.

If you decide to do it, keep us posted on the progress.

You have to choose the Sub! It' morally wrong to use a Carolla.

Thanks! Any idea on how to contact him for pix, etc, or if I'm just missing something? I went to "members" and didnt see unhatched on there.

I figured a subaru would be the best platform for what I want to do, since they are well proven in the off-road environment. Now I gotta go to the pick-n-pull with a tape measure and measure out leaf spring mounts, crossmember mounts, make a game plan for a steering setup, WMS measurement, etc.

BTW the reason I'm considering this (or even thinking about it) is so that my wife can have a killer little rig for her around town driving. If I use a suzuki samurai transfer case, it has a 1.3:1 high range ratio, which would make up for bigger tires to a degree :D

OK I did a search and found that his username is lumpycam. Found the website, too.

So the extra transfer case can be added.

Now my next question is this: Do subaru's have an actual frame? Or is it unibody type construction? Thanks.
