I just bought a Subaru 360 van and it needs a ton of work. I'm going to upgrade the motor and drivetrain and one of the options I actually saw on a customized Subaru 360 van was an air-cooled VW motor and I assume the drivetrain. But, the biggest problem is these vans are about 10 inches narrower then a VW bug. I was thinking you could possibly narrow a pan to make it fit. Has anyone done this and if so, what was involved? Any input or direction would be greatly appreciated.

Building your own pan halves is pretty straight forward. Cutting down the torsion tubes out back and abandoning the torsions in favor of coil overs or air ride would also be fairly easy. If you went with an IRS rear, you could have axles made to length. The rear is going to be way more difficult than the front, but the front has it's issues as well. Narrowing the beam that much might require rack and pinion steering or something. When you narrow the beam as much as what it would take to get it under that little Subby, the driver's side steering arm gets really short and can cause scrubbing, terrible bump steer and other issues.

Yeah, that is the one that gave me the idea of using an air-cooled motor, but there are no real details about the frame and driveline except that he used custom made a-arms front and back.

After reading this I did a little more research and saw a 550 spider(see pic)

that used the vw driveline and they removed everything but the axles and added 2/4 link type setup and I think that would work, what do you think? I would do the install in the normal direction.

How difficult is it to cut down the axles?

I would definantly consider a rack and pinion for the front.

If you can't narrow the beam and rear end enough you can always run Bosozoku style wide flares!

There are places that do it for drag cars and whatnot. It's not something you can do yourself. Maybe the housing on a swingaxle, but not the axle itself. I'd stick with IRS.

Doing a short axle swing is WAY easier than IRS. You can buy 3 and 5" shorter axles, although you may have to do some digging for the 5" as they aren't made by SAW any more. I found mine in Europe and shipping was pretty cheap.

Cut the rear torsion tubes, use 21 5/8" torsion bars and early spring plates with the snouts on them and matching torsion covers, easy peasy.

The front is also pretty easy. You can do a rack like I did or you can center mount a the steering box and use a jointed steering column.

If I were doing your project, I would abandon the VW floor pan altogether and start with a simple tube chassis. You can use square tube for the main part, it's easy to cut, get, square and build off of. Draw out your Subi 360 dimensions on the garage floor and build from there. Here's my narrowed buggy project. Probably won't apply to much but might be some stuff you can use or get ideas from.

the swedish style vw trikes, where the engine is between the riders legs, use a shortened axle and custom swing arms - see this us site
