okay everyone, i have a project that i am about to undertake... any advice, assistance, criticism, whatever is appreciated. Here it is: I have two 12A motors, good condition that i am about to tear down and build into ONE motor. i am going to make it a 4 rotor engine. i have some ideas on the eccentric shaft, but have no one local who can do the machinework for me.... I will be running twin Distributors on it, as well as twin oil coolers and pumps and a really high output alternator to manage everything. The intake system is going to be a little tricky, as i didnt really want to do twin carbs.... any ideas on that one? I was thinking of custom making an intake manifold to run to a 700 holley, but i dont know if thats even gonna be enough... should i run two carbs on two seperate intake manis? exhaust is all going to be custom, but i will need someone to do that work for me as well.... Let me know what you all think... oh and the vehicle it is going into will be a stripped out shell of a 1980 SA. i will also need some help with the rear end, as i dont think it will be able to handle what is going to be coming back there....

 

good luck..

 

sounds like its going to be a challenge.......but good luck.

 

okay let me rephrase this... i dont really want words of encouragement... i want advice, hang ups, issues u think might arise, constructive criticism..... help me out people... ive gotten word that this has been done before, and is currently in operation on a 787 supercar, but imagine it in a stock production SA RX7!??!?! imagine the possibilities there.... what issues will i come across u think?

 

take pics! good luck

 

The 787B won the LE Mans 24 hour race. Then the Rotary engine was banned from the race series because people fear what they don't understand I guess.

There is a company is England that custom builds 4 and 6 rotor engines. The name is on the tip of my tongue but I can't think of it at the moment. If I think of it I'll post a link to their site. Other then them, I think the next best think you will find on this site is people who have experience with Mazda's 3 rotor engine, the 20B (I'm sure you've heard of it). Its a factory engine, not one made from multiple parts from 2 rotor engines. I have a pic of one disassembled, though I don't own one and have no experience with them. I also have a pic of one installed in a 2nd Gen RX-7. Again, not my car. Hope maybe this can help a little seeing the parts and comparing them to what you have. Good luck and keep us posted. I'll give you a link to that company if/when I find it.

 

Ok, the site I was thinking of is www.hurleyrotary.com but after checking it out, I don't see anything about 4 or 6 rotor engines, just the 20B. You could shoot them an email and ask if they have any experience with more rotors because I think they did work with bigger rotary engines at one point.

Good luck.

 

thanks bud. thats a good place to start... im figuring that i will definitly need the help of companies a lot larger than mine.... with experience with rotary a lot more extensive than mine.

 

I would suggest you go with a modified ford 8.8 rear end for that. It would take all the abuse you want. Also, Grannyspeed sells the already modified and bolt in ready for the first gen.

I think it's a great project but you take two 12a n/a that developed 100hp stock to make a four rotor that developed 200hp!!? If you port it and put a big carb, maybe you can make 300hp, but 300 is what a 13b-rew stock make exept you will make a lot of torque.

The project is great but the benefit aren't

Yay for 3 year old threads...

 

lol yeah i totally abandoned that project after the e-shaft shattered after one rotation.... i took two e-shafts and welded them together and balanced it on a machine.... well had someone do it for me. upon full assembly, and crank over it cracked the welds and went totally out of wack!!! oh well!!!

 

No shame in trying.
