Has anyone thought about putting a high performance rotory engine in a 924. I want to do this. If anyone has experience in this please talk to me. I want to put a natural gas rotory engine in my 924 and convert it to burn H2.

[dwak]

I thought h2 engines were still a pipe dream and I believe there are a lot more rotary-less Mazdas out there than Mazda less rotary engines.

Here is a Mazda-less rotary engine:


and it will fit anywhere

[cakemakerman]

actualy all major car manufacturers are working on hydrogen engines and building prototype cars, mazda, ford, bmw, etc. however so far i have not found any h2 engines for sale

BMW has a 7 series that runs on hydrogen. I saw it my R&T issue this month. It's a stock engine, they just converted the fuel system to hydrogen and used the injectors to control the spray.

As for a rotary, I know an awful lot about this subject . What you'll want is a Mazda 13B, the second most common rotary in the world. The most common is the 12A. Avoid this motor like the plague, as it is heavy, unreliable, guzzles gas, and has next to no power potential.

Get a turbo 13B and you'll be fine. Or a 20B, depending on where you are. We never got the 20B in North America, but the Japanese and Australians did, I'm not sure about the Europeans. The 20B is a triple rotor variant of the 13B, which has two rotors. Any 13B from 83 and up is good, with the preference being the 86-92 single turbo RX-7 motors, as they have the cheapest power potential.

Phew, another ridiculously long rant.

Oh yeah, these are very compact engines, with a traditional flywheel clutch system. It'll definately fit, and I'd be happy to give you any advice you need.

better get a BIG fuel tank , idustrial bottle gas suppliers are not that abundant,might be a long drive between fillups . oh and I think its expensive, and the feds dont like it when individuals buy bottled hydrogen , makes them nervous. and you need to take hazmat classes to get the permit to transport it. and the gaskets are notorious for leeking , seems its hard to find a material that is soft at 400 below zero F SEE NEXT POST

a rotary in a 924? Been done before. It's called an RX7

[Cbass]

Heheh. It's funny cause it's almost true.
God damned f***'n mazda. Sorry. Umm, hydrogen isn't that hard to do. I'd just stick with gas for now, and let the R&D people build good conversion kits.

[Rick MacLaren]

If you want maximum boost for a 931 engine, convert it to propane and then turbocharge it.

[Cbass]

Gaahhh!! Propane? Guess it has better compression qualitahs. Sorry, can't communicate the accent.

Fuel cell companies are working on hydrogen projects. Ford and Chrysler are into it, along with Mercedes. It may be possible to buy hydrogen in a few years at your uh, gas station. BMW does indeed have a hyrogen powered internal combusion engine going on sale in Germany soon. Your idea sounds far fetched. I will go still farther. In ten years it will be possible to go to a wrecking yard to convert our elderly 924 cars to hydrogen fuel cell power, and have electric drive.

[cakemakerman]

So these bmw engines, is there a way I could order one. From my understanding they can either burn H2 or gasoline with the flipp of a switch. So you think its improbable to but one of these hummers in my porsche? Why can't I be one of the first persons to drive a H2 powerd porsche?

The problem is that hydrogen is not available for automotive use to the general public. At least, not yet. In Germany, it will be in the near future. Try the websites for Ford and Daimler-Benz. Type in fuel cells. Also try Ballard Power. Also Hydrogen Investor. It is a real eye opener. In ten years, you will be able to do what you want. Or you could just go to the Ford or Chrysler dealer to buy a new hydrogen powered car. Most manufacturers are working on this issue.
