I would take that same setup with two small turbos and turbo system that's high revving. which will make it behave like an Rx7. MAJOR CHANGE: Dry sump system so the engine can be mounted in almost the same spot as the rotary. RX-7 PERFECTED.
mine is a rotary still and that will never change. i never liked them before i got one. my plan for my fc was to buy the car for the chassis and swap to a volvo t5 in it since they're really common here in sweden and pretty easy to make 500 ish hp, the angelic sound they make don't hurt either. but i fell in love with the rotary and realised that my opinion on them was based on uneducated peoples on the internets biased opinions (wich i was one of). alot of the roumors about how fragile rotarys are from people not knowing how to build them. any 1.X liter engine is fragile at or above 400+ hp on all original motor. why do people expect a rotary to handle something an equally sized piston engine can't? you will have to change rods atleast if you want to make that kind of power on a 1.6 - 2l 4cyl. and maintenence is just checking the oil a little more often than on a piston engine if its a unmodified rotary, nothing too special really. the extra maintenence comes with modfying the engine, but thats not really more than any other modified engines (depending on how you modify it). a 7l v8 will more reliably make 500hp than a 3l sixcylinder and that will make that same power more reliably than a 2l. thats what ultimately decides how reliable it is, size and if its designed for it.
depends on the car. R34 GTR? VK56DE naturally aspirated as that in of itself can be found in my locally junkyard. but like i said i prefer cars i can nab at a local junkyard for cheap. swap a reliable engine. and drive off and beat it everyday without issue. thats the reason why the LS is so popular facts wise. cheap, reliable. easy to find parts. and can be done in your garage(unless your lazy and uneducated. fuck off)
The entire car has a timeless, classic sports car look. It is not dissimilar to the C5 Corvette. What is a 300Z? I know of a 300ZX, but there is a Z31 AND Z32. Nissan never made a 300Z. I suspect you are talking about the Z32. If so, good looking car, but is still not as good looking as the 240Z from 1970 to 1973.
I love rotary engines. There are a ton of fun. They rev to the Moon. But they break as a car guy, I want to stay in the driver's seat as much as possible, and not under the hood
No they don’t. I have owned my FD for 6 years. And beat the shit out of it. It’s never broken once. It comes down to finding a tuner that knows how to tune a rotary!!
@@brianawd Just like you said, "Finding" a tuner. They also break more often then piston engines period. There's no reason to act like they don't. Fun engine, but not reliable.
More so it’s about the tune and most people not realising they consume oil by design and don’t premix their fuel properly or check their oil anywhere near often enough.
@ they don’t break that often when tuned properly. That’s easy to find now days. 13b have gone bottom 6s at over 200mph. That’s on stock rotors and rotor housing. Show me a stock piston that can go bottom 6s. So again they are strong internally. It all come down to who tuned the car. They get a bad rap because people picked them up not knowing shit about a rotary.
the crown vic that Kyle and Brent built for lemullets would be so cool to be seen totally fixed up and youre actually around to review. it was actually hilarious to watch!
The FD RX-7 is my dream car, I believe it to be a beautiful work of art. If there were ever to be a suitable motor for a swap, the K-series is just that.
Just signed up for projectcarexchange, have a 1986 Ford LTD w/ 3.8L V6 & 4 link. I am the second owner, bought to be a daily, found out the trunk is about the size of a briefcase.

K swap the world! My grandpa had a rotary Mazda pick up in the early 80’s he was constantly working on until he traded for late 50’s VW bug and a motor in bushel baskets.
@@SomeOne_86 I mean, the mazda 3 is fairly new still and was designed for a transverse I4, you can't just stick an i6 in and expect it to fit. The mazda 6 is dead because it was so old it could have its own driver's license. Maybe if they drop a new mazda 6 it could? I kinda doubt it though.
@@androiduberalles To give you some context, even before the new CX 90 and such came out with the 3.3L, there were rumors that were later confirmed that Mazda was working on an Inline-6, RWD Mazda 6 as well as an SUV.

None of that's true. 20+ year perpetuated internet myth. I have the corner scales of two fds. One rotary, one V8. Weight balance was a hair better with the V8.

So much miss information in this Video. Mazda has the apex seal issue sorted when the turbo 2 was introduced. They are a reliable motor. It’s simple. Check the oil level. And toss in some pre mix on each fill up. That biggest one. Find a rotary tuner and not some shop that says sure we can tune it. Seen so many people take there car to a tuner only to find out they thing you then a rotary the same as a piston motor.
All the solutions you bring up doesn't change the fact that those problems exist, and a lot of car guys don't wanna read a book on which rx-7 they should or shouldn't buy.
They don’t have an apex seal problem!! The problem came when people tried to turbo an NA rotary. That apex seal was not designed for that. An NA rotary will last a long ass time if you do normal maintenance. Just like a rotary that was designed with a turbo from the factory does just fine when tuned properly. Any engine will be un reliable if not tuned properly. And normal maintenance on a rotary is checking the oil when filling up the car. They are designed to burn oil from the factory as they have an OMP that injects oil into the rotor housings. Just because you have to check the oil regularly does not make them unreliable.
@@brianawd "Just because you have to check the oil regularly does not make them unreliable" No, it makes whatever in question, HIGH maintenance; checking fluids is part of maintenance, even if no repair is done. We shouldn't have to even worry about checking this or that more often than another platform. Also, can you be more specific? One should be checking the oil regularly on every engine. What is your definition of 'regularly' with regards to the frequency of checking say, the oil on an LS1 or LS3? SMFH
@VBMichael_D Towards the middle of his post, he says to check it at every fill up. Which makes a lot of sense, considering that they burn oil on purpose.
@@VBMichael_D you do understand how the oiling system works on a rotary? Checking the oil at each fill up is just routine maintenance because they have an Oil metering pump that pulls oil from the pan in injects in into the rotor housing. By design they burn oil.so it requires a simple checking of the oil level and keeping it topped off. Even other manufacturers like Mitsubishi advised checking oil levels every few fill up on the Evo as they can burn up to 1/2qt every 1000miles. Every engine is different. Just because I need to check the oil level on my FD when I fill it up does not make it high maintenance.
I'm currently working on an sr20det swapped Rx-8 for all of the weight balance and "soul" reasons that David talked about. The SR is even lighter and shorter than the K.
@@3xeplodng_3agle_studios Also consider subaru EZ30. But either way a screaming flat 6 feels just right. And the engine sits low just like the rotary so it fits nicely under the hood.
@@phantomflame0658 ooh that's right. I love the ez engines because they're basically "poor man's Porsche engines" Porsche even helped design them... Iirc? But I always forget them still because you never see them built. Out of sight out of mind I guess. 😅 thank you!
That car sounds really really good tho 😮makes all the right sounds honestly I kinda like that more than the rotary engine ngl. And like you said David u also get more reliability and yes I love the taillights too.
Here's your website feedback- I clicked on about 10 cars and only 1 of them wasn't sold- yet they're all still on the website even though they aren't available...
Putting a damn 4 cylinder into an automobile (4 cylinder are good for supersport motorcycles), when one could've put a V8 or I6, both of which are more powerful and vibrate less, is not magical. It's asinine.
As someone who loves Honda and loves the k series, this swap is one of my favourites for the fd. However, it will always be missing one thing. And that is the sound of a rotary.
Better than a boat anchor, and the shop who built that car does good work. That said if you come back to colorado, come check out the rotarys here that are faster than that car. Worst problem I've had aince building mine is sheering off some engine studs.
I missed out on a nice 1995 RX7 back in 1999 and I’ve regretted it since. I’m thinking about actually buying an FD but I’m not sure if I want to go with the domestic left hand drive or import a newer JDM model. Honestly I’m leaning toward JDM
I want someone to put the GR Yaris engine in one. Or a J series, 2GR, or an LV3. Or a 5-cylinder. All/any of those would be sick as hell. *EDIT:* Also, fun fact, Civics even as old as a 4th gen actually have LONGER wheelbases than the FD RX7. You're confusing wheelbase stability vs stability brought by good suspension geometry, the latter of which is something that most mid-engine swaps based on FWD subframes lack.
97.5 % correct . 99.5% OF average automobile owners aren't Carcaine people an suspension geometry is jibberish when u speak about it. An if u have general car modifying knowledge an think a 3 way adjustable shock is easily setup. Even a lifetime suspension mechanic still has more to learn. Lol 😊
@@DaVe-iSnOtHoMe.MaN.LemmingsWeB Real talk. Man, I really wish I had a platform to stand on with all the knowledge I've pursued. I think I could make some pretty sick cars if I just had the facilities and a few friends to do it with.
Cool car, and I can appreciate the work it took to build. I'm still not a fan of deleting the pop-up headlights and swapping into a K24. It's what makes it an RX7. If I won it, I would either see the engine and buy a 3 rotor in it or sell it and buy a amother RX7.
I wonder how hard it is to keep those pop ups alive 30 years later. Maybe since it was a give away car, they took the easy route with the fixed headlights?
So, I’m watching the video. Love the swap, love the quality from what I can see, when I see it. The Mazda logo on the hatch doesn’t match the Mazda logo on the steering wheel.
truth be told and i do this in alot of car games. reliability is more important than looking cool and being cool. i have 2 older GTR's in one of the games i play and they dont have their RB's because they arent cheap or reliable. the R34 has a VK56DE procharged and then the R32 has a VK50VE twin turbo. by the way both reliable japanese V8 engines that beat out the RB engines in both price and reliability. you always gotta factor in price in reliability. thats the big reason why LS v8 engines are the literal BEST of everything because its the perfect example of what an engine is supposed to be. cheap. reliable, makes big power on anything you throw at it and fits anything you want it to be in. all engines should at least strive to be like the LS in those examples
Dude, it’s funny that you mentioned the 2JZ-I just acquired a DART block 2J. Don’t know what I want to build it for. Thought RX-leaning more towards the original Supra. 600 is easily attainable. What do you think?🤔
I will be honest, i am a honda fan and this makes me feel weird. However, considering the reliability that was gained, i would do the same. Also, for the high rpm fans, hondas dont rev less than rotaries.
I think it's practical if you want to have the style of the RX7, and according to your review, it maintains the handling characteristics/feel of the rotary setup. The only argument is the purists who love the sound, and characteristics of a rotary engine.
I think the K20 would fit the character of the car better since it is lighter and can rev higher but a K24 is naturally going to make more power because of displacement.
As a big fan of Ls motors and swaps I 100% agree with his statement of an RX7 losing some essence of its JDM heritage by swapping an Ls in it. Honda motor on this is perfection 🤌
Rotaries are neat, but they're a labor of love. And while you can rebuild them and improve them, at what cost? To me, the BIG selling point here isnt simply the similar weight and RPM range, but also availability and value. They're as cheap or cheaper than LS engines to get swapped into a car, and build/upgrade. Parts are available everywhere too. My point: not only does this swap make performace sense, but makes wallet sense since the whole swap will cost less than having someone rebuild your rotary or buying a new 13BREW from mazda.
I definitely agree LS swap should have bought a Corvette, but K swap sounds like ya should have just bought a s2000 with a hard top. Still a cool car, but miss that unique rotary sound.
It's interesting that no one blames replacing their 2-stroke head on Yamaha because they ran it out of two-stroke pre-mix on the trail. Mazda had quite the write up when you bought one of these new about understanding the maintenance intervals are not the same. I have all kinds of old literature about including the book from the designer in Japan. It didn't have an apex seal problem please stop perpetuating this myth. It had an operator failure to understand their vehicle problem. That's the reality. Like when you see those videos of people who put diesel in their car cuz it was cheaper.
Nah, stop lying. These rotaries are unreliable at the best of times. If you say that you have to do multiple special maintenance to keep it running, that means it's not reliable. It's not a myth. Clogged cats can detonate a engine, swapping to a catback exhaust could blow your engine, not premixing your fuel here and there could cause diminished life, Mazda did a recall for the RX-8 because it was blowing engines before 60k. Again, not a myth. They're a finicky engine, it is what it is.
Exactly. The rotor, apex seals, side seals and corner seals were all lubricated by engine oil that was injected into the housings. Engine oil is not meant to be burned in a combustion chamber so carbon would build up and then chunks of carbon could break off and take out seals. This oil injection was a compromise because you can't expect a typical driver to bother put 2 stroke oil in the tank when filling up. The manual actually recommended redlining the engine at least one time per drive. This blows out the carbon and prevents it from building up. If you baby a rotary, it will not last but if you regularly run the piss out of it, it will last. Of course the perfect solution is to disable the oil injection system and run premix 2 stroke oil in the tank.
RX-7 is a timeless design, but feels kind of wrong without a rotary, though I get K24 is more reliable. K series engines are amazing, plan to put a K24/K20 into my Honda CR-Z eventually.
For the most part I'm a purist. In general, if it's and RX-7, it should have a rotary engine. That said, if done well enough, I'm not against a nice swap. But a lot are just cobbled together, and the end result, despite hp and torque numbers, just doesn't seem worth it. Edit: The rotary's issues weren't due to people who didn't know how to maintain them, they were due to people who just didn't maintain them. Not keeping a weekly eye on the oil level of an engine that used oil as part of it's combustion. Keep an eye on oil and coolant levels, and you're good. Modifying for more power? Tune accordingly and watch out for lean conditions. Lastly, the FC's burning up? Leaking fuel pressure dampeners going unnoticed until major leaks - and that's nothing to do with rotaries themselves. I've seen a LOT of neglected rotaries! Of course you're going to have issues.
I think the K is very close to being complete nonsense in an FD, and in fact /is/ complete nonsense in an RX-8. First we have the torque problem. The K24 finally manages to make similar off-boost twist to a 13B, but the K20 actually loses that fight. This isn't world-ending, but the FC and later 7s (and definitely the 8, by way of being another 2-300lbs fatter) could use more twist rather than less. So now we have to run more boost to make the same output, and due to how both motors behave from an airflow standpoint, the K is going to be late to the party every single time. Then there's getting them to actually fit. K20 makes this easier by being shorter deck height (you know, so the hood would be able to close fully without dumb panel gaps, but it still fouls on the firewall of an RX-8), but puttering around off-boost it nearly may as well be a 12A. Transmission selection is also problematic. The irony is that the LS/LT motors are outright better options, but you really may as well just buy a Corvette at that point.
One of the best looking cars ever imo. K24 seemed to be a fitting swap, obviously sounds nowhere near as good as a rotary or even an LS BUT the LS sound just doesn’t suit the car always throws me off

@@DaVe-iSnOtHoMe.MaN.LemmingsWeB Real talk. Man, I really wish I had a platform to stand on with all the knowledge I've pursued. I think I could make some pretty sick cars if I just had the facilities and a few friends to do it with.
Cool car, and I can appreciate the work it took to build. I'm still not a fan of deleting the pop-up headlights and swapping into a K24. It's what makes it an RX7. If I won it, I would either see the engine and buy a 3 rotor in it or sell it and buy a amother RX7.
I wonder how hard it is to keep those pop ups alive 30 years later. Maybe since it was a give away car, they took the easy route with the fixed headlights?
What color is that?
So, I’m watching the video. Love the swap, love the quality from what I can see, when I see it. The Mazda logo on the hatch doesn’t match the Mazda logo on the steering wheel.
This is super cool, nice video
truth be told and i do this in alot of car games. reliability is more important than looking cool and being cool. i have 2 older GTR's in one of the games i play and they dont have their RB's because they arent cheap or reliable. the R34 has a VK56DE procharged and then the R32 has a VK50VE twin turbo. by the way both reliable japanese V8 engines that beat out the RB engines in both price and reliability. you always gotta factor in price in reliability. thats the big reason why LS v8 engines are the literal BEST of everything because its the perfect example of what an engine is supposed to be. cheap. reliable, makes big power on anything you throw at it and fits anything you want it to be in. all engines should at least strive to be like the LS in those examples
Didn’t check out the website yet but thats an awesome idea it just filters out all the people that dont need to see the project car lol.
Man. This thing is beautiful
Got the LZ steering wheel gotta love that
Owned a 1st and 3rd gen RX-7. Anyone who says silly sh#% like "You just have to maintain it!" have NEVER owned one. This is the perfect build.
Smart swap. The rotary engine is a nightmare. Unreliable and not worth it in my book. This is really cool.😂❤💚💜🤑😎
Crazy clean swap, dang 🎉
Dude, it’s funny that you mentioned the 2JZ-I just acquired a DART block 2J. Don’t know what I want to build it for. Thought RX-leaning more towards the original Supra. 600 is easily attainable. What do you think?🤔
is200 or landcruiser would be good
I used to would have said put a 4G63 in it… buuut the lighter weight and larger displacement K24 is a very solid choice now days.
when is the drawing i cant find it anywhere on the site
I will be honest, i am a honda fan and this makes me feel weird. However, considering the reliability that was gained, i would do the same. Also, for the high rpm fans, hondas dont rev less than rotaries.
Nice. It’s like an alternate universe S2000
Project car exchange app would be amazing!
I think it's practical if you want to have the style of the RX7, and according to your review, it maintains the handling characteristics/feel of the rotary setup.
The only argument is the purists who love the sound, and characteristics of a rotary engine.
Anyone know what blow-off valve this car is running? It sounds so freaking good!
I don't recall if it was said in the video, but I'm curious how much boost and power it makes.
I love this build but the colour's what sets it apart from the rest
Can you make a complete car section?Because Facebook marketplace has the same fake book problem with complete cars
About to k24 swap my 3rd gen Supra targa. Cant wait
That is crazy clean.
I think the K20 would fit the character of the car better since it is lighter and can rev higher but a K24 is naturally going to make more power because of displacement.
Well, do you want to replace apex seals and mix fuel?
Skyactive Technology just kicked in yo!
It would be the 4th best option after a 13b, 20b and then 26b
I've seen this car in person!
I love it man! It's gasoline, good n nuff
As a big fan of Ls motors and swaps I 100% agree with his statement of an RX7 losing some essence of its JDM heritage by swapping an Ls in it. Honda motor on this is perfection 🤌
Rotaries are neat, but they're a labor of love. And while you can rebuild them and improve them, at what cost? To me, the BIG selling point here isnt simply the similar weight and RPM range, but also availability and value. They're as cheap or cheaper than LS engines to get swapped into a car, and build/upgrade. Parts are available everywhere too. My point: not only does this swap make performace sense, but makes wallet sense since the whole swap will cost less than having someone rebuild your rotary or buying a new 13BREW from mazda.
Nice setup. 👍🏻😎🤘
I definitely agree LS swap should have bought a Corvette,
but K swap sounds like ya should have just bought a s2000 with a hard top.
Still a cool car, but miss that unique rotary sound.
No lie I thought of the same exact build
It's interesting that no one blames replacing their 2-stroke head on Yamaha because they ran it out of two-stroke pre-mix on the trail. Mazda had quite the write up when you bought one of these new about understanding the maintenance intervals are not the same. I have all kinds of old literature about including the book from the designer in Japan.
It didn't have an apex seal problem please stop perpetuating this myth. It had an operator failure to understand their vehicle problem. That's the reality. Like when you see those videos of people who put diesel in their car cuz it was cheaper.
Nah, stop lying. These rotaries are unreliable at the best of times. If you say that you have to do multiple special maintenance to keep it running, that means it's not reliable. It's not a myth. Clogged cats can detonate a engine, swapping to a catback exhaust could blow your engine, not premixing your fuel here and there could cause diminished life, Mazda did a recall for the RX-8 because it was blowing engines before 60k. Again, not a myth. They're a finicky engine, it is what it is.
Exactly. The rotor, apex seals, side seals and corner seals were all lubricated by engine oil that was injected into the housings. Engine oil is not meant to be burned in a combustion chamber so carbon would build up and then chunks of carbon could break off and take out seals. This oil injection was a compromise because you can't expect a typical driver to bother put 2 stroke oil in the tank when filling up. The manual actually recommended redlining the engine at least one time per drive. This blows out the carbon and prevents it from building up. If you baby a rotary, it will not last but if you regularly run the piss out of it, it will last.
Of course the perfect solution is to disable the oil injection system and run premix 2 stroke oil in the tank.
K swappin an fd i think is a great choice all around.
RX-7 is a timeless design, but feels kind of wrong without a rotary, though I get K24 is more reliable. K series engines are amazing, plan to put a K24/K20 into my Honda CR-Z eventually.
Anybody know the paint code for this color?
Is it still RWD?
For the most part I'm a purist. In general, if it's and RX-7, it should have a rotary engine. That said, if done well enough, I'm not against a nice swap. But a lot are just cobbled together, and the end result, despite hp and torque numbers, just doesn't seem worth it.
Edit: The rotary's issues weren't due to people who didn't know how to maintain them, they were due to people who just didn't maintain them. Not keeping a weekly eye on the oil level of an engine that used oil as part of it's combustion. Keep an eye on oil and coolant levels, and you're good. Modifying for more power? Tune accordingly and watch out for lean conditions. Lastly, the FC's burning up? Leaking fuel pressure dampeners going unnoticed until major leaks - and that's nothing to do with rotaries themselves. I've seen a LOT of neglected rotaries! Of course you're going to have issues.
Rx7s one of the sexiest cars ever made.
I miss my 94 Rotary Rx7 😢 shout out Banzai Racing who built it… ugh miss it
I know its a bigger heavier engine but I'd love to see a BARRA in an FD
Epic build.
The crazy thing about it... The C4 looked just like RX7...
I’m amazed you didint review Ben’s from G&G
First thing I would do if I owned one lol so sick
THANK YOU...FINALLY!!!!
Best of both worlds, get the beautiful design of the FD and the quality engineering and reliability of the Honda.
Love it best swap
The gap between the hood and bumper was bugging me until I saw the intercooler lol.
The FD is the sexiest car ever made
Good swap, i want to see a porsche flat 6 in it, low center n all...😅
Id love an FD. Id like to do an RB26 swap.
Im a Gm guy but power per weight is a thing and the market is good for k’s or j’s awesome car bet is does auto cross like a tree frog
A dressed LS doesn’t weigh much more than a dressed K series and makes more power and torque.
@ You can mess up the 50/50 and the handling
Perfect engine swap❤
I think the K is very close to being complete nonsense in an FD, and in fact /is/ complete nonsense in an RX-8.
First we have the torque problem. The K24 finally manages to make similar off-boost twist to a 13B, but the K20 actually loses that fight. This isn't world-ending, but the FC and later 7s (and definitely the 8, by way of being another 2-300lbs fatter) could use more twist rather than less. So now we have to run more boost to make the same output, and due to how both motors behave from an airflow standpoint, the K is going to be late to the party every single time.
Then there's getting them to actually fit. K20 makes this easier by being shorter deck height (you know, so the hood would be able to close fully without dumb panel gaps, but it still fouls on the firewall of an RX-8), but puttering around off-boost it nearly may as well be a 12A. Transmission selection is also problematic.
The irony is that the LS/LT motors are outright better options, but you really may as well just buy a Corvette at that point.
Next step for project car exchange! *_AN APP_*
They are not unreliable at all. People just neglect them. Stop skipping out on putting good parts and see.
Love that color
Pretty stinkin rad
I would love to swap in that 2.5 5pot Audi has into one of these
One of the best looking cars ever imo. K24 seemed to be a fitting swap, obviously sounds nowhere near as good as a rotary or even an LS BUT the LS sound just doesn’t suit the car always throws me off
Everyone says the civic has a short wheelbase and I don't know why. My hatch wheel base is longer than my friends mk4 supra....
Thats is soo cool❤
Gawwsh I love that car 😮❤
I think it’s great!
It's really odd seeing this after seeing it in person. My friend actually worked on it and it's a pretty shptty build for what they are touting lol
