Rodney, Jim did the black rotary conversion and the website is:- http://www.eliseusa.com/rotary.shtml The video of the Rotary car can still be downloaded and Jim can still be contacted at the bottom of the same webpage. My previous discussion with Jim is edited below:- Re: Rotary DeLorean 28/10/04 The spec of the engine was:- The 20b engine is a 2.0 Litre, 3-rotor rotary wankel engine, 300HP, and 297ft-lb of torque at 3000RPM. It was originally sold in a very large heavy car, the eunos cosmo JC, sold by Mazda in 1990-1996 in Japan and Australia. It resembles the 929. The miata (mx-5) is known as the "eunos roadster" some places. The Cosmo was available only with an automatic transmission. Pics are available at http://cp_www.tripod.com/rotary/pg09.htm with some more specs. The horsepower figures are 'claimed' at 280hp because that is the legal limit for street cars in Japan. Independent testing found that the 20b is consistently ~300hp. Regarding what I'd change if I did it again, I'd probably use the 13b, 2-rotor. Parts are MUCH easier to find, and it would fit in the DeLorean better. The 20b and the extra gear in the g50 transmission ended up making the unit very long, only fitting in the D frame with significant modification. The 5-speed box or the 2 rotor (one rotor and side-housing shorter ~6") would make a better fit. It's also lighter. They also have much less electronics than the 20b, which came in a state-of-the-art luxury car in the 90s (read, thousands of wires). Turbos are often used more than superchargers because they take away less power to operate well. They're also more often used with small-displacement engines. The import engines generally rev to higher RPMs, and turbos are more effective/efficient than superchargers at higher RPMs. http://photos.noroads.com/dcs2004?id=499 Adding NOS to your car is probably a reasonable modification that can be done without spending the time and money on conversion. Also, resale value on conversions are JUST NOT very good in general, and are horrific with the Delorean. You can pick up a nice "wet" NOS setup for ~$600USD, and you could expect a reasonably increase in HP. You just have to be willing to change NOS bottles when they go empty, which is only as fun as you can make it. I don't think I'd put the NOS in the trunk though, that seems a little far away from the point of use. I'm not sure if there is a reasonably better place to put on though- maybe in the pooka behind the driver seat? Maybe make a hole in the rear pontoon? Well, I guess it depends on the size of the bottle. Jim The NOS prices you saw are pretty high, you can look at some systems at http://www.jegs.com/cgi-bin/ncommerce3/CategoryDisplay?cgmenbr=361&cgrfnbr=6 66 Remember, you don't have EFI. It's mechanical Fuel Injection, and may make a different depending on the setup. -----Original Message----- From: dmcnews@xxxxxxxxxxxxxxx [mailto:dmcnews@xxxxxxxxxxxxxxx] On Behalf Of rodney rael Sent: 10 December 2005 04:20 To: dmcnews@xxxxxxxxxxxxxxx Subject: Re: [DML] Porche transmission compatibility in Delorean Dave, Mark: Thanks for the info....
