Besides lots of money, what do you have to do to build a 4 rotor engine?

nasty nate 7 · 11-05-2005, 08:09 PM

you need a longer 13b or 12a eccentric shaft(customed) to join the 2 blocks together, bigger adapter plate and longer bolts. thats just to start, the rest is im not so sure about.

HoosierDrifter · 11-05-2005, 10:20 PM

sukimoto · 11-05-2005, 10:32 PM

Fiver2 · 11-06-2005, 01:54 AM

Almost sounds like the motor from the 787B

Engine:
Type: Wankel Rotary (4)
Displacement: 2622 cc
Horsepower: 700 bhp @ 9000 rpm
Torque: 620 lb-ft @ 6500 rpm

TeamSLIPdrifter · 11-06-2005, 04:49 AM

Ive seen that car before.. are you sure its only 500 cause the last time i saw that car it was around 700 horses. Yes, they did mass produce 4 rotors in the early 90s until GT, F1, and a few other categorys decided to ban the motors cause they were too godly (i could be wrong on that so dont quote me). And id imagine it would be very rare to find one of those 4s. Oh and you should see the power they can put down with a turbo

cerian_ca · 11-06-2005, 10:55 AM

I heard that they made a 20b, 3 rotor in a car that looked a lil like a 929.. someone knows about it?

yah the name of the car was a Mazda Cosmo. It was twin turbo to i think...

drift7 · 11-07-2005, 03:57 PM

four rotors were Never Mass Produced and not available to the public ever

Only 2 or 3 rotors where available to the public and the 3 rotor was only in japan in a Cosmo- sedan car- not sports car...there are 3 and 4 rotor aftermarket shafts and parts available from Australia or Japan But they are differnt than the factory components, and require a differnt set up...

if you are really interested in the 3 or 4 rotor after market stuff PM me and i can help you get it!! But it costs bank$$$$$$

Is that FD the 4 rotor 12a that was at 7 stock?

TeamSLIPdrifter · 11-09-2005, 03:43 AM

I thought you could cause looked into it before and i found a ton of info on mazda's 4 rotor engines and where to buy them but that was like half a year ago

Tranquil · 11-10-2005, 05:34 PM

RX-7 guy here to clear some things up.

Mazda never mass produced the 26B engine, known to others as the ungodly power maker featured in the 727.

Bridge ports are very common in rotaries, as for high idle, yes that is true. They usually idle at 2k RPM, and you must sustain high revs. Impractical for street driving, good for drifting. The typical rotary "brap brap" comes from the irons overlapping each other due to the port.

Also, if you are well known, Mazda of Japan does have the molds to produce the core block for the 26b, but that is $125,000. Only two men have purchased them and they were for racecars, but it was banned from most series so who cares now?

BTW, I'm thinking about a 20b swap into my FB. They can be had for as little as only $4k, and make 300 N/A with a small street port. Jesus Padillia has the fastest all motor RX-7 with only a 13b that makes 9 second passes with only 300 horses. He used to run a 20b, but its been outlawed in drag series everywhere.

Well End History Lesson (yes I did join the forums just to post this, I'm kinda bored and I was reading up on technique. I mostly frequent Ohiodrifting.com)

drift7 · 11-10-2005, 06:56 PM

Are you sure?

was it factory Mazda? I know they were available for race teams. but not to the public. and not really mass produced?...

Slammed_GSL · 11-10-2005, 07:36 PM

Nope, Mazda made 4 rotor's were made for LeMan racing only, private firms make them to order. The JC Cosmo was production from 90'-96' in both 13b and 20b versions. I love this car, Brad Berger in Seattle has one that he brings to our meets....sweet car
