The TRUTH About Building and Owning a 3 Rotor 20B Mazda RX7

[@KennyatHumble]

This comment section teaches us all that the people that know the most about 20B engines are the ones who have never touched, cannot afford, nor will ever own one. Lots of internet experts here. Let me remind me you, every single RX7 with a 20B in this video was built by us.

[@Mitch3343]

[@donmerrigan2362]

Rotors Magazine there's a guy in another videos comment section cursing at and telling everyone that he can find a complete 20b swap for 5k. This even though the cheapest 20b on eBay right now is 6300 including ECU and wiring harness only.

[@alycestapleton]

Rotors Magazine i live here in oz or Australia outside of japan Australia is one number in rotary engine been doing them since the early 80's many years before anyone else around the world even i have worked on them indeed they cost alot most of my mate here had or have one they spent more time at the workshop then driving them

[@gwrcpa]

Hey everyone. I have a 20B 3rd gen RX7. I highly recommend if you are going to do the conversion that you push the transmission back 3 inches and get custom drive shaft. This is because the subframe that people normally use does not allow the engine to be back far enough and the power steering rack needs to move too much. Basically, I had the subframe kit and the car felt disconnected. I spent an additional 3K to move tranny back and it made all the difference. The car felt like stock again and handled way better.

[@brandonbayon8100]

This made me appreciate people with 20B engines even more. Respect to all the Rotary owners who ignore all the risks and seek enjoyment

[@sandervanderkammen9230]

The 20b is definitely NOT a performance engine, it was cobbled together for a failed luxury car...

[@sandervanderkammen9230]

@Chris Farley Both companies have a reputation for low cost, entry-level cars targeting first time buyers.. Nissan launched the Infiniti brand with limited success but remains viable in some markets. Mazda's reputation is definitely on the low-end market and it's attempts at launching luxury brands such as Eunos, efini and Amati have all been failures.

[@bobspence5322]

I would love to see a video explaining the process/cost of importing these cosmos! I've been contemplating pulling the trigger on one for the longest time, but I don't know what to look for.

[@MajorMatt79]

That is so funny you said that, i have loved rotors from day 1 but thought the Cosmo was ugly AF back in the day, i haven't seen 1 for a while and i actually like it.

[@jonnyindianajd]

I had a 76 Cosmo in about 1990, fully loaded, power everything 5spd white, red and blue trim work. I was young, had no money, so wished I had it now. My step dad had a early 70's Rx3, it was about as fast as his 65 hypo 289 Stang. I was really into rotaries in the mid 80's in the Silicon Valley. Ron if your reading this, it's John, Scott's friend, summer of 85, San Jose. At any rate, a Cosmo would be would be the Pinnacle for me, not an Rx4 or a Rx7. The only other would be an Rx3 SP. Not that that would be all that, it's just a cool old sports coupe from Japan. John from Noblesville.

[@howardjames7559]

When you slightly mis-stamp a "B" on a block you get an "E"

[@dj4monie]

Thank You for the video, very informative. I never thought a 20B would be so expensive to have a reliable and powerful car based around one. You are right, the internet make you believe they are grown on trees but that isn't the case at all, very involved and expensive. Even more so if you don't have an RX-7 already...

[@TheForcedinductn]

Great video but don't forget about us FC RX7 owners, the FD wasn't the only RX7 ever made :)

[@KennyatHumble]

FORCED-INDUCTN only true RX7 ever made :)

[@TheForcedinductn]

Wouldn't that be the FB as it was the simplest and purest?

[@TonyToretto25]

No, because the engineers couldnt get a watts link right on such a primitive suspension design.

[@bluecollarjose]

I seen a fb featured on 1320 videos. The turbo bigger than the motor. Highly modified of course.

[@rogerdavis2056]

A long ,long time ago a friend of mine had a rotary truck after that ride I bought a 79 rx-7 got it running a then the rotary bug hit me! Previously I was into V-8. I have had 4 rx-7, one rx-8. Time to get another one! Great video, Thanks.

[@Slays_Media]

My dream car is a naturally aspirated 20b swapped fc3s. Since rotary territory is foreign to me aside from what I read in forums and see in videos, I already figured it would be pricey as hell to have a clean and reliable setup. Since this video cleared that up for me, I'll definitely put that idea off until later in life. In the meantime, I'll just stick with an sr20 swap. 😆

[@177SCmaro]

Swapping engines is more expensive then a lot of people realize. Just swapping a basically stock rebuilt 2zzge and C60 into a Celica GT cost me around 5500-6000 (the cost of the engine, trans, clutch, ect.) and that was doing all the work myself. And that is an engine Toyota designed to go in there.

[@JohnCherubin]

i want a 20B when i finally get an RX-7 but i know its not easy to find plus expensive...this video broke down the cost and time needed to do the job right. Great video!

[@angusjoejohnson1036]

I have 2 20B converted FD cars and I can tell you it is really cool but truthfully you can make a 10 second 2 rotor on pump and water meth a whole lot cheaper. That being said, the sound of the 3 rotor is intoxicating and will last longer because you run less boost. The torque is also a huge plus. I suggest doweling and running a smaller turbo on the street. I run a BW efr 9180 on water meth and the car blows the tires out in 1-4 gears. I see 15 psi by 3000 rpm.

[@joserotary9636]

[@RX7FDfreak]

Been considering a 20b swap in my FD for quite some time since its my favorite rotary. Glad I found this video to better prepare myself, thank you!

[@genya3162]

so howd it go?

[@DJToneRI]

Did you ever do it

[@RX7FDfreak]

@@DJToneRI still rocking the 13b but I did completely strip down the vehicle to be repainted and rewired. So “like new” being restored with modernization. I was more or less convinced to keep it all original motor wise. More into tracking super sport bikes these days. I’ll never sell the car, and the 20b is still an option.

[@willthacker5182]

20k! Wow...I'd do it if i had a fd sitting in my driveway w/20k in the glove box. Rotary's are pretty awesome though. I prefer piston engines, but being into all things mechanical, im definitely intrigued by the rotary. Theres a reason why ppl put them in small aircraft. They must not be too unreliable.

[@Happymali10]

Thank you for this video. In Germany the rotary-community itself is tiny, and 99% of it is "if you change the wheels, you're a monster and belong in jail". So there's NO solid knowledge on 13b/20b-engines, swapping them or modifying them. Only a lot of "I did it kinda-sorta" or "If you do XY it should...."

[@tscooter22]

Original FD (95% stock) owner here. 'If' I were to do a 3 rotor swap (no way would I do it) I would make it NA. Hell, I'd even consider going old school with a carburetor. I don't want 700 hp, but I do want a reliable power plant without the complications and heat of a turbo. I'd be fine with ~300 wheel hp and the advantage of consistent throttle response you get with an NA engine. I like to drive the backroads and the track, not race on straightaways. The stock FD has plenty of power to get you between the turns on public roads. I had a 91 Miata before I traded it for the RX-7 and had a blast backroad bashing with that car! The original 12a and 13b RX-7s were much more simple back in the day! I'm not a big fan of all of this computerized crap. Simple EFI would be fine for me too. Nice video, btw. Thumbs up and subscribed.

[@michaelbrown9031]

Great vid. A lot of food for thought and a massive damper on my 20B plans haha. Will always be the dream. Keep up the good work, really enjoy the channel

[@1truzilla458]

He's right about everything he's saying. I've got a 20b in my FD And I've spent in total 40k. 16k of that was engine. I'm still not running right. And on top of that alot of people don't know what there doing. So everything he's saying is correct. I'm actually finishing my other build of my skyline and that's been cheaper to swap a RB30 into that than my RX7. I'm going to finish that and save up and send it out to maybe rotors magazine.

[@KennyatHumble]

If you need help, hit us up on facebook. We regularly build 20Bs, every FD in this video was built by us.

[@1truzilla458]

You do realize that a lot of 20Bs come from cars going to the scrapper anyways, and that, in some countries, you can also put a 3-rotor together yourself/have it put together, or extend a 13B.

Do you really live in a 3rd world country? It is just the price of an average new car in the west but still expensive. :)

[@kayceebrooks1428]

An average new car is going on a 3 or 4 year financing term, you're not typically going to finance a 30 thousand dollar project. It's already a bad idea financing a depreciating asset, it's an even worse idea to finance a depreciating project.

[@k9forkids]

or you save up a couple of month and add an junkyard 5.3 with a turbo and just do it instead of sitting on a couch dreaming about $30K Rotary builds. To many people are dreaming about the exclusive and most exotic builds, instead they could go with what is cheap and available and go out there and have fun.

[@KillaRock404]

To me putting anything but a rotory in a RX is sacrilege. Yes swapping a 3 or 4 rotor into anything is going to be time consuming and expensive, but it's not about the money if you go that route. My dream is to have a 3 rotor RX-8, sure it will take time (I"m fairly young and I need to do a couple things before I can get just spend 30k freely like that), but it would be my ultimate car goal. From my research, LS swaps cost about 20k+ so why just go for it with the extra 10k? I know you can fit a turbo with a 3 rotor into an engine bay. Can you even fit a turbo if you LS swap it?

[@kasper_429]

How do you know what letter code the engine is? I've found several 20B engine packages for sale through JDM importers, anywhere from $4500 to around $7000 depending on the importer. Also, I've found a 20B swap kit through a company called Defined Autoworks, $1670 if you don't want A/C, and $2070 if you want to keep A/C. All they require is a shortened lower intake manifold so the engine clears the FD hood, and they offer the modification for around $500. Stupid question, but will the stock 13B-REW manual transmission bolt right up to a 20B? Or is there an adapter or any modification needed? This is all still a dream for me right now, as I have yet to find an FD for sale near me for a reasonable price, but I'm just doing research anyway.

[@deftonesfan81]

Very excited for the cosmo build!! Cant wait to see what you do!

[@michaelhooper2888]

Bro in New Zealand you can pick up full front end of of cosmos with 20bs for like 5k and that's 3.6usd that's with every thing except engine mounts

How much of a 20B can you build with aftermarket parts? Or do you have to rely on factory Mazda oem to finish it ? I'm more familiar with chevy or mopar V8s and some of them contain no " chevy parts " but this can be very expensive engine build. Just wondering if as time goes by and more engines get push to the limit and go kaboom dose this mean that there becoming more rare and harder to maintain in a running condition?

I’m pretty sure the late rx-7’s in Japan came stock with 20b’s.. after they discontinued in the US, they kept up production in Japan for a few more years and put 20b’s in those. They also kept the 13b but some came with 20b from factory. From my knowledge of course, I could always be wrong.

The big question... why are rotaries for sports cars only and not ordinary cars? Just not worth it?

[@zsquints]

To answere your question back in the 70's there were cars and even buses that had rotary engines in them at the time. The reason as to why they stopped putting rotary engines in consumer vehicles was mainly due to inefficiency, when the gas crisis happened those vehicles pretty much died and 4 and 6 cylinders started their reign into the average consumer car.

[@neoanderson7]

People have alot money available to be doing 20B swaps into their FD's. I think this happens more in the US than anywhere else. I know alot of people up here don't do 20B swaps. When we attended DGRR this year, there were at least 4 FD's that had 20B's swapped into them. The rest of us were normal 2 rotors but with a variety of people running twins or single turbos. I think you spend alot of money getting a decent single turbo 13B running in the FD. Let alone a 20B. Can't even imagine the amount of fuel you'll be sucking down.

For sale in Sydney Aus right now.. (Fresh built 20b bridge port turbo. Series C. Lapped, nitrided, stud and doweled, balanced rotating assembly, lightened rotors, have new Pac apex seals, billet drive shaft etc. 7.5k aud) that's $5,878 usd🤔

Really like the video. I was that guy when I first got my FC then the more i looked into the more I thought fuck that, 2 rotors are good for me. But I was wondering if you could do a similar video about the 13B-RE and swapping that into an FC?

[@KennyatHumble]

I sold my Cosmo-RE swapped 10th Anniversary a few months back. It's pretty straightforward though.

[@21Noire]

Rotors Magazine I remember I saw it facebook lol. Glad to knoe its straight forward for the RE swap. I fine nice write up in fc3spro about it. Still not a cheap swap by any means but much more realistic for me

[@challenger3967]

I would love to do an NA one as well and contemplated doing one. However, cost justified the means. I did not want to spend that kind of money for my RX7 daily/SCCA racer. I could purchase all the parts at cost through Mazda Motorsports then, but the housings and eccentric shaft would kill you? When Mazda ever makes a modern 3 rotor NA or turbo will drive down the costs. They need to build some new sports cars with the 300hp NA and 450hp turbo with the same weight class cars of the 80s/90s. Unfortunately, your next RX7 will be a hybrid like the NSX and 80k?

Why does the orange FD on the dyno have “Rotors Performance Built Break in Tune 18psi -730whp”? I took that video at our 417rotary dyno day with Gaby Skern. I don’t remember meeting anyone from Rotors Performance and we couldn’t get the FD to make a full pull cause of fuel issues. Did they take this car to you guys later on and it eventually put down those numbers?

[@KennyatHumble]

We weren't known as rotors performance at the time. The owner of the car is a co owner of rotors.

[@therx7kid]

I’ve been out of the loop for a while. When I saw the clip I took of the orange FD on the dyno, it brought back memories of that club event, (it was a long ass day). Were one of you guys there? There were quite a few people that drove down from Kansas.

+Chris Richards I was not I wasn't in the picture until 2013.

[@MajorMatt79]

Epic Vid bro, very informative and spot on. For all the muppets who thumbs down the video, you have no idea.

[@truckloadofrhymes1]

It's actually quite common here in Canada to see 3 rotor RX7 lots of FCS

[@alexmartinez280]

The 20b is such a special engine I don’t get why more people don’t build high compression NA 3 rotors. Plenty of power especially in the glorious top end. Less stress, less complication and a serious weight loss. Light weight sport cars go with light weight power plants. Throw in ITBs and IMO it’s THE perfect set up. If turbo is your thing, building a high compression, low boost yield BIG power and not so unbalanced in power delivery. I drive an S65 M3 with 415bhp stock at 12:1 CR. Introducing just 6 lbs of boost takes output to 625-650bhp. Rotary engines are no different in that way. Mike Vargas is building this exact set up and proving my point. 450whp on 6psi!!! It is the drivers set up for those no just wAnting straight line pulls which is EXACTLY WHAT THE RX cars are. Comment below and let’s shine more like light to the upcoming holy grail RX 13/20b engine setups. High compression is the best way for true well balanced sports cars. I will build an FB soon to Group C Rallye spec. It dominated in its day and will dominate the streets as well over the accepted path of present day low compression high boost lopsided builds. The talent is already available, this fresh idea is all that’s needed teamed up with the rotary heads attention.

[@epoxeclipse]

So what would we be talking MPG / oil consumption on DD'ing one of these?

[@MrAusterror]

DD = Daily Drive? If so, and the 20B is stock, the highway fuel consumption is not bad, on a good day 9.5L/100km. City driving, about half that. Cosmo are not so great at stop start city traffic, they were built for the freeway.

[@marcusquinones2425]

Good point of view

[@nick_2294]

Does anyone know the name of the track playing in the background?

[@nick_2294]

Nah dude still looking..

[@MrMeoow91]

If I am going to get a 20b, I will keep it stock and NA. It's the most safe way to make the engine last long.

[@BrianFrichette]

Straight talk. Thanks man

[@rx7fd329]

Why not swapping it to mazda cosmo stock engine? It's 20B right?

[@damionbates5463]

Hey, hopefully you see this. I have a 2004 RX8 that I think needs way more power. I want to either swap in a 13BREW or NA 20B. I know about how much a 13BREW would cost to swap, but can you give me a rough estimate on how much a 20B swap would be? Would I be able to retain traction control and all the normal electronics? If I did all the parts minus the electronics would you guys be able to the electronics if I paid you? Really interested in doing one of these swaps. Thanks

[@nk0723]

Damion Bates get someone to build you a short crank 20b. It uses 13b parts, but you might need a billet centre iron from what I've been told. Start asking around rotary specialist.

[@collinmcclenahan9957]

Did you even watch the video? Jesus

[@rayban5737]

Any engine conversion mildly modded roughly about 20k

[@jrc630]

Does it fit in 1983 rx7????? Please let me know...
