Hey Guys

Does you guys ever see any 8 swap into 4 rotary ? Because i m plan on my project to swap 26B into my 8, I know it s alot of work but it's would be crazy at the end.

Hey Guys

Sure i will try it and let's make it happend, It's will get alot of welding work and it's would be great for custom engine bulid, My goal is 4 Rotary with twin Turbo at least :fingersx:

sure Ikea we can race after we r done with our engine swap :wink2:

Good lcuk with that. what i wanna know is where are you getting this motor from. talk about 1 of the hardest motor to find on the planet

Exactly my point... Something tells me that someone that doesn't realize it's a 4 ROTOR not a 4 rotary will never be able to find one let alone make the build happen.

DK, or should I call you Drift King? Do you have an extra 100K+ sitting around? Because that's probably about what it would take to even consider making this happen.

http://cp_www.tripod.com/rotary/pg03.htm Seeing that they stopped production plus the factor that the engine bay room would not support this motor with out tearing up the inside of your car or extending the front end about a foot and a half, i would love to see your progress if you actually manage to obtain the motor. I have never seen or heard of it being installed in a RX7 let alone a RX8

DK RX 8

well first you should start by calling it 4 rotor, not 4 rotary.

second, you're talking about 50k for this kind of project because i don't think obtaining one would be anywhere near easy, so doing a custom job would be your only shot. was it like 10k for a custom e-shaft for the scoot fd?

idk, gl nalin.

OK DK, I'm going to give you the benifit of the doubt on all of this...


I'm going to assume...
...that your bad grammar is due to English not being your primary language
...your eagerness to do this is because you feel you've got enough time & money to accomplish it
...your lack of rotary knowledge isn't as bad as it seems
...you realize the amount of customization involved, and know good fabricators who are willing to help you.


Given all that, here's my advice to you:
- Give up looking for a 4 rotor engine. You're not going to find one. Even if you somehow do, it's going to be ungodly expensive, and there are probably only 10 mechanics on the planet that can help you with the install & tune.
- Find an empty 8 frame and start from there. A 4 rotor will never fit in the engine bay as-is. Your best bet would be to start from the ground up. Make good friends with an engineer because lots of carving will be involved, and you do NOT want to lose structural integrity with that much power.
- Research the Susuki Escudo. Somehow they mounted twin V6 turbocharged motors - one in front, one in back - to build a "V12 TT" rally car. 4rotors have never been done on street cars before, so a twin-Renisis setup might be the cheapest option. I recommend the Escudo method because you've got 2 seats and a decent trunk in the RX8 that could easily house another 13b. Trying to line up 2 motors in the front of the car would be nearly impossible, as well as SEVERELY throw off the weight balance of the car. Placing a second motor midship would comprimise handling less than any other method.




...and if you are just a kid with outrageous hopes and dreams, face the facts and realize that faith is going to accomplish nothing here.

Was going to mention that someone like you or RG might know more about it but didnt wanna say it without being sure... guess I was right.

Anyways, if he has the money and time to put into this, then it'll be a very interesting process. Even if he doesnt have a place in mind to do the work, there are members here with plenty of knowledge to help. I dont know about you guys, but if he's serious about this, I'd really like to see this happen (out of interest mind you, not doubt).

btw zoom44, just for general knowledge on the forum... how much would you be looking to spend to buy one of those 4 rotor engines? Not that most of us could afford it, but just so we know...

There are no signs for smaller, extremely common words. If 90% of the time he's communicating with other people he's able to leave certain words out and ignore the standard rules of grammar, when he starts typing, he'll type things out the same way he's used to "saying" them.

I'm no expert by any means, in fact I'm barely able to change my own oil, but 100K for a 4rotor swap????? give me a break, just because the guy wants a 4rotor engine doesn't mean he HAS to get one of the few mazda built for the 787B. Can he just put 2 13b together like many other people have done????
Also I don't see why it wouldn't fit??? does any1 has any measurements on the 26b??? According to HurleyRotary out of the UK a 20b(or adding a 3rd rotor to a 13b) only adds less than 5in to the total length of the engine so wouldn't a 4th rotor add another 5in or 10in total(from 13b to 26b)?????
There's a few places around the world that would make you a 26b, and I can assure you none of the will ask you for 100k, I'm not saying putting a 26b on an 8 is cheap, but I really don't think it'll run all the way to 100k, I'll say 50k, 60k tops.
Like I said, I'm no expert but by reading some of the answers it sounds like it's impossible in every way imaginable.

in Japan, people have done a 4 rotor swap by putting 2 13B-REWs together, but they couldn't fit that into a convetional car, they did put it in an FD, bmw 335i etc etc though, plenty of vids on you tube

Khronus, we are being dead serious, get 100k+ or its not going to happen, I'm serious, because 50-60k will get you in a gigantic and fiery crash because your car will suck after that, might not even be able to go straight in a line, everything will be fucked up, you will have to strip everything, reinforce the chassis with streel braided cages and roll bars, every fucking thing, go wide body to support the weight........omfg, the list goes on and on, can't you just go buy a lambo? god

you dont just buy the engine and finish... I dont know exactly how tight of a fit a 3 rotor is, but it's not exactly roomy. Also, no you cant just stick 2 13B together. that's the basic concept, but not the end of the process. The eccentric shaft would have to be custom made and it'd have to be very well made. There'd also be a lot of custom fabrication that would go into it. If it required no real modification to the frame or anything like that, your estimate might be accurate, but if it gets into something such as frame work, then it's going to cost a lot to do right.

Another issue to mention that I dont think has been brought up. Does the OP realize he will not be passing emissions if that's a requirement? And I can only assume gas mileage is not an issue...

I know you need an eccentric shaft, that's why I posted the links to the sites they all make them, AMV racing makes a 4rotor shaft for less than 8K. I also know you don't just super glue the 13bs together, but all in all 100K is just 2 much for that much you can def. get that six rotor engine in Hurley Rotary into the 8. I say go for it, post your progress and let us know the step by step cost of the project, once that 1st one is done, more will follow.

PEOPLE!!!!!!!!

Doing a 4 rotor its not the end of the world, you can put the block togheter for less than $20,000, the hard part for me its the ECU set up,if we had good ECU programers in my country my car would have a 4 rotor a long time ago

go to ausrotary.com there are more than 50 4 rotor cars in australia

the real thing is why? why would you spend the money when you can make the same amount of power for a fraction, a side port 26b would have about 400 RWHP you can get that out of a 13b with a big turbo kit!! an a PP can get up to 600 rwhp but it would not be a good street car

Im doing a 20b swap into my car right now, it is much cheaper than most people say it is, if you go turbo its a little more but I havent decidet to go turbo or NA

You probably won't be able to find a complete 4 rotor for sale. A kit would probably be the easiest route to go and will set you back $9,500. With the price of housings and side plates I would say estimate on about 20-25K for the motor. Getting it to fit I'm sure could be done, though the subframe crossmember will need to be moved forward and since you'll need a custom oil pan anyway you could probably squeeze it in.

Not to mention he had the resources,and the funds Judging by what your asking its just a thought as of now and you have no clue how your going to even going to obtain the motor in the first place, if anything i would just go with a 3 rotor and turbo the hell out of it

Hmm, I went to the drags yesterday and there were at least 3 quadrotors there, the mazsport bmw and 2 fd's (i forget who they were)

If you can fit a quadrotor in an FD i dont see why you couldnt do it in an rx8

The problem the quadrotor guys seem to have is trying to tune them

I think you'd spend 20K in electronics and tuning alone once you get the motor IN the car. Hell race teams spend that much about that much to get the same on pushrod V8's nowadays.

Damn Mazda, they need to make this happen. A 20B Renesis theoretically could produce about 350 crank HP in it's stock form. That would be a nice RX8! I hope one day I have a ton of money as the 4 rotor is very appealing and isn't a crazy idea. A N/A 4 rotor would be nice, you could have tons of reliability (if it was tunned and set up right) and produce tons of HP w/o the need of FI. 2.6L isn't big by any standards, I'm tired of Mazda's B.S. with this 1.3L design. The renesis would be nice in a go kart or a Lotus Elise but they should scrap this 1.6L concept and go bigger. Add at least a 3rd rotor!!!! I love the renesis engine but the RX8 is too heavy of a platform in my opinion. If the car was around 2000 lbs it would be a total blast. Not that the RX8 is bad, but it just seems they could have done more.

The problem is the side ports. The middle rotors will be choked from having their exhaust ports siamesed together.

Yep. I don't pretend to know everything about it, I've just heard that peripheral ports are better for 3+ rotors. Seems to make sense to me, especially since the exhaust ports are almost maxed out on size on the Renesis from the factory. RG was only able to reshape CRH's or else he'd be into the water jacket.

According to Paul it was near 100k for the engine and that wasn't a Rene 13b. Only one group has managed to put together a 3-rotor out of the renesis 13B somewhere in England though no one's ever seen a dyno of it and they put it in a FD.

How much power are you shooting for? You won't hit 7's N/A (as cool as it would be to see that).

I suspected so, that's why I haven't posted. I figured his pics weren't his when he posted them. This thread always smelled fishy.

LOL, I can't believe that I fell for it. It's just hard to believe that someone would go to that much trouble to fake something like this.

I mean, where did he expect this to go? Was he going to post some rotary drag clips from Puerto Rico to show off "his" car? And how sad must your life be to care that much about getting props on some Internet board for something you didn't even do?

Oh well, at least we can have a rotary drag clip, that will make it all better:
