Out of curiosity, do you have any pictures of all your projects somewhere. Really interested. Thanks
None of all my projects. I do have a geocities web page but it's grossly out dated. Maybe I'll update it soon.
Not familiar with the 360's but an old Honda 600 might work if you could adapt the fwd.
The Subaru 360 had a 360cc 2 stroke 2 cylinder air cooled transverse mounted in the back. Maybe I could adapt a VW trans and a single rotor back there.

They're too rare now. Besides I'd rather do a 2 rotor in one if I could.

The last time I looked for a Subaru 360 for sale, one was selling for about $2000. Maybe I should look for some other small thing for the one rotor.

The Honda 600 was the precursor to the Civic, it too had a motorcycle engine, 600 cc's. The shifter was mounted to the dash. Neat little cars not much bigger than a bread box. Made the old Minis look big.

Jeff are you talking about the mazda Bus?

[QUOTE=Jeff20B]Thanks. I try.

I don't have any picks of the delivery van or any info. Until this thread, I didn't even know what these engines came out of, though I suspected some low reving thing from Japan like a Luce or something. https://www.rx7club.com/forum/showth...t=delivery+van

It was RX3SP who said it came out of a delivery van. He even posted pics of the crazy oil (not ATF) filled torque convertor. No wonder so many import 13Bs have that little drain sleeve fitting at the lower corner of the rear plate. I've blocked off two so far. I also had to install a blind plug in the shaft of the engine pictured in that thread (the painted one, not the old rusty one lol). It was a bonafide delivery van engine that I brought up to tallport R5 standards by swapping in a Y intermediate plate and RX-4 rotor housings with US-spec port timing. I then ported the intakes out to '74 spec and enlarged the exhaust ports 2mm up and 2mm wide so the owner could use it in his REPU as a backup engine. He mentioned possibly installing it in a 1st gen instead so I threw on a GSL-SE oil pan, which happens to be compatible with the REPU as well so he's set regardless of what he does with it. He just needs to come get it out of my garage lol.


The engine you are describing I think was the one mounted in the mazda bus that sold back in 71~74. it was a 20 passenger mini bus (a little larger than a 15 pax chevy and was manily used in small inner city areas..... their is photo of it on DMR's (??) website i saw it once, I think I actually saw one in a junkyard back in 85, but had no clue what it was at the time.

trochoid, that must be the inspiration for the shifter in the dash on some recent models.

The Subaru 360 also makes the old Minis look big. I wanted one very badly about 15 years ago. Sadly I had no money and now they're highly saught after, driving the price up.

kenn chan, I think you are correct. The engine must have come from the AP bus (or whatever it's called) because I've never heard of a rotary powered Mazda delivery van until RX3SP mentioned it in that thread. I gave him the benefit of the doubt and started to refer to it as such. Plus monito.com, where I first learned about the bus, is appearantly in need of restoring, so no one can access the info about the bus at the moment, or anything else other than the first couple pages.

I think you're thinking of DMRH. His "DMRH David Morris Rotary Historian" page still works but he's not doing the importing thing any more. too bad.

Do you think you could find the bus on his page? I think I saw it on wikipedia once too.

An engine oil filled torque convertor with a manual transmission makes sense here. It would put more power to the ground because you control when it shifts. Driving with that much weight would quickly wear out a regular clutch. The necessity to be smooth to keep your riders happy is also a factor. Plus there's no need to scream the engine because it's a freakin' bus. Although I wouldn't let that stop me.

Anyway the torque converter probably extended clutch life almost indefinitely. Imagine dumping the clutch, it grabs with minimal slipping/wear, and the torque convertor smoothly starts turning the input shaft. Of course that's an overly simple example as I'm sure clutch pedal inputs had a fair degree of control over small movements of the bus, like any normal clutch. It's just interesting to consider the possibilities.
