QUOTE (soloracer @ Nov 15 2005, 04:54 PM)
I'm putting a 3 rotor peripheral port engine into my 914. I just got all the parts I need for the rebuild ($3400 Canadian. Yikes!) The 3 rotor (20B) engine only came in the Mazda Cosmo that was available in Japan and Australia. The Cosmo was a high end luxury car along the lines of a Lexus or BMW. If you want an engine you have to get one from a car at the wrecker. Mostly what you are buying the engine for is the irons and e-shaft (crank shaft). You can use 13B/13B-REW housings, rotors, bearings, etc on your rebuild. I scored a spare e-shaft on e-bay for $500 US just in case the one in my core engine needs to be replaced.

As for the 4 rotor there indeed was one made by the factory. It came in the famous Lemans winning race car called the Mazda 787B. It still is the only japanese car to ever win at Lemans. Shortly after it won they restricted or banned the rotary from competition and will likely be the only time a rotary wins at Lemans. There are a couple of companies that make 4 rotor e-shafts but they are not cheap. A friend of mine is going to work at the #2 rotary engine builder in Japan and he had the opportunity to buy a 4 rotor e-shaft.....for only $9000 US. What a bargain! (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) He figured that it would cost him around $30,000 Canadian to build a 4 rotor perpherial port engine and that is with him doing all the labor for free. Custom e-shafts can be bought from both Japan and in New Zealand/Australia. There is a company called "Scoot" in Japan that has a 4 rotor RX7. Do a search on the web for them and you should find several videos of the car. I have them saved to disc but would need someone to host them if you can't find them elsewhere.

banksyinoz: Good to see you again. I thought you mentioned that the 20B PP was running 51 mm throttle bodies and I asked why they went smaller than the 55 mm that I had purchased for my car. In this thread you mention they are using 55 mm throttle bodies. Which one is it. Not trying to start anything. I just want to know what they were using and if it was the 51 mm units did they have a good reason for not going bigger. It could be important to know on my build up if I am going with the wrong throttle body.

P.S. Nice first gen. That looks like a stock factory turbo. To my knowledge we couldn't get those here. Too bad because I bet it really goes.

soloracer has all the good information about the 4-rotor e-shaft. I can’t add much to his already complete list. I do however have one tidbit of information that you may find interesting. Locally to me here in Canada we have a shop full of creative mad men like my self that have come up with a way to connect 2 two rotor motors together. On the dyno normally aspirated it pushed out over 1000hp. You’re next question will probably be how long is the assembly. Believe it or not it’s about the same length as the factory 4 rotor. The power plant is slated to be installed in a 3rd jen Rx for testing this summer. I am sure that I will be shot soon after posting this as it’s suppose to be top secret.

Now that is very interesting news,, I will be keeping an eye out for more info! Thanks guys.

Does anybody out there have a currently running street driven rotary 914? I'm just curious, how rare my conversion is. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

You gotta really love the rotary engine to stick it into a 914. But once you're done,, you got a really unique ride. Post pics of your car,, I'll be sure to comment at least once. (IMG:style_emoticons/default/biggrin.gif)

Has anyone tried running a 3rd generation RX-7 radiator set up in the 914? I am working on this right now and was wondering if anyone has had problems. I have a racing beat header and exhaust that will work for someone that is staying normally aspirated if anyone is interested. It is for a 13b and mounts to where the rear sway bar bolts mount.. I had it on my last 914 and it worked great.

13B,

Got any pics and dimensions for this radiator? I'm guessing it has very good cooling capacity to cool the little Wankel!

I think it is 15" X 30" wich should fit between the headlight buckets quite well. I will be using the aluminum racing radiator that is 3" thick. It is completely sealed with no radiator cap since the 13B gsl se has the radiator cap on the engine itself.

You have any pics of the exhaust. What muffler if any does it use. Could you please post it here or send to me.

Thanks

I got my radiator from www.renegadehybrids.com check under the SBC conversion for the coolling package. You can also see all of my pics at www.913b-gt.com. There has been issues with cracking due to body flex. They completly float the radiator in the shrowd to avoid this.

I have heard there is a nice rotary 914 in Waco, TX. A body shop friend said he saw it but I haven't been able to find it yet. I think the owner's name is Wade. The story is the car came from Kalifornia.

Well it's been along time since I last updated this thread. Sorry for the long gap.

My car is running! and getting better in small steps, as I street tune my FI. I ditched the megasquirt because I couldn't overcome an ignition problem of my own doing. I am now running a stone age Haltech E6K FI. The programming software is in DOS!
I had some rubbing I couldn't get rid of in the front with my 16x7 Fuchs, so I went with the 16x6. I thought people had problems with the rear rubbing? Tires are 205/55/16,,, any thoughts?
