A lot has changed since this video was made, the factory computer can be tuned to run turbos and people are getting 400+hp out of them reliably. Also, series 2 Rx8 has 3 oil injectors per rotor and even the series one can be tuned via Mazda edit to inject more oil. This has been done on my Rx8 by Roland Wankel Garage. Maybe you should do an updated video on this topic? 👍🏻
If this is the case I’d love a updated video! Everywhere else says this engine can’t make power reliably at all and to just get a rx7 motor if you’re determined to stay rotary and make power though if you’re not determined to stay rotary everyone says to engine swap it which I personally don’t want to do I want it to be a rotary
@@350zKiller ironic name 🤣, love it. But same bro, the rotary is such an underrated engine, pushing out somewhere around 232-236 Hp stock. I just want a lil turbo for fun at this point
I've been planning on turboing my RX-8 for quite a while, and have solutions to most of these problems. As far as compression ratio and engine wear, I'll just run low boost on the street for everyday driving. I'll only turn it up to higher boost when using race gas on the track to prevent detonation. I'll also go totally overboard with the cooling system to help with heat buildup. I plan on getting an aftermarket standalone ECU for engine management anyways, and because of that it will also free up engine bay space. That will also help with reliability, as boost doesn't usually kill rotaries, bad tuning does. I'll also be able to massively turn up the oil injection and have it draw from a separate resivoir of rotary 2 stroke oil. I have my engine pulled out of the car right now, and with the battery, air box, and ECU removed there would be plenty of room for a small turbo. Just like you said, there's a fair bit of relocation, possibly including water lines, that would have to be done lol. As far as cost, I wouldn't be buying a kit. I have an uncle with some exhaust fabrication equipment and I know how to weld, so the piping could be done for relatively cheap. I'm not going for crazy power anyways, 300 whp on the street is pretty fast already, and on race gas I could probably make 350. I find that even the stock power is all I need for any somewhat legal driving, so any more will mostly just be useful for shenanigans. I'm not going for 0-60 or 0-100 times, I'm more about preserving the nice handling and driving dynamics while giving it a little bump in power to keep up with similar cars in the straights. I am sort of going full on streetable race car build, while still keeping most of the luxuries that I can. There's definitely some serious obstacles and you nailed them all on the head and explained them in a simple and easy to understand, yet in depth way. However, I'm up for a challenge when it'll make my dream car even more amazing. Who knows, maybe some day I'll swap the 13b MSP Renesis for a 13b REW if I really want to chase some huge power.
Your essay has a lot of information, Lol. By the way, my next project is turbocharger. Could you tell me what is the turbo kit you used? How many miles your rx8 with turbo? Have u tuned by yourself or shop? What is your normal operation PSI? Seems like I have a ton of questions. But if you can answer me, I would really appreciate.
晏晏成博 I haven't actually done the turbo yet, but I'll answer your questions as best as I can based on what I know about it all. I wouldn't have a kit, but I'd custom fabricate everything using a welder and pipe bending equipment. If you're after a kit, I believe the one that is easiest to find is the Greddy kit. It's far from perfect, but is relatively cheap. It'll increase the power but drop the RPM that peak power occurs at. I haven't heard much about the specific longevity of a turbo RX-8, but it would largely depend on how often you hit boost. I would highly, highly suggest a boost controller that you can turn wayyy down for everyday driving, like 2-3 pounds when you don't absolutely need the extra power. That'll help to keep the wear to a minimum. Also, be sure to follow the normal rotary maintenance tips even more thoroughly. I'm going to start with a self done street tune, and just focus on reliability. I would recommend to have a shop tune for ultimate power and safety once it can be afforded. It seems like most kits are in the 5-15 PSI range, I believe that anything above about 10-15 you really have to start looking into high octane racing fuel, depending on how long you want to stay on boost. If you're going to hit boost for a quarter mile and then call it quits for an hour, then you could possibly get away with 15 on pump gas and a very, very good tune. However, if you're going for multiple hot laps around a long race track, even 10 pounds could be a bit much on pump gas. Upgrading the cooling system will help reduce the heat which can cause detonation, and having an excellent intercooler system can make a difference as well. Carbon buildup can be a cause of detonation/pre-ignition as well, so be sure to redline it every drive and cruise over 3000. I would suggest around 3 pounds for everyday driving, and maybe bump up to around 8 for weekend fun. only go to 10 or more if you know you'll need it to win a race, or if you want to show off for a quick pull. Boost can also build up lots of extra heat, and overheating is a guaranteed death sentence for a rotary. Have a coolant temp gauge that has an accurate readout and under no circumstances let it go over 210°F. Try to keep it well below 200. Really the number one piece of advice I can tell you is to have a reliable, safe tune. Rotaries hate lean conditions, and detonation can kill them in a split second, so tuning to absolutely avoid those things is most important.
Worth reading every single word, you should be proud of the amount of knowledge packed here. Dude, i sincerely wish you all the luck in the world, so that you can make your idea come reality! Oh yea, and thanks for the support :)
changing the dowels in the housing can stop the apex seals from making contact with the side of the irons and side fumbling of the rotor as you increase the boost. the renesis has a bad habit of twisting itself apart and better dowels can make a huge difference.
[Update to current date] The community progressed quite a lot in the last years, in my opinion turbocharging the Renesis isn't hard, can be cheap if you keep the oem ecu (there are better tools and tuners out there than before) or you can go with an Adaptronic PnP ecu that keeps all electronics working as stock but better management. With a 6 ports engine you can safely reach around 340 whp, which isn't bad and way cheaper than swapping a 13b-rew. That's without touching the engine core, if you prepare the engine for boost you can achieve higher whp and be "reliable".
Probably your best video for too many reasons to type. Thanks for all your RX-8 Rotary effort on your UA-cam channel. I'll be documenting my RX-8 build if anyone is interested.
Yes, I think we'd all be interested in following your boosted RX8 build! It's a year later, and there's still no content on your channel though... Give us turbo-rotary porn man!
Boost doesn't kill your engine, a bad tune does, as for lack of lubrication, if you are tuning the engine, you can always increase the OMP oil delivery. It's not hard it's just has to be done properly. The ECU won't let you do a live tune, you have to reflash, launch it, log and repeat. On a stock rx8 you can squeaze at least 20nm of TQ and around 15HP with a little tune.
Putting the finishing touches on my turbo rx8 today... I got a used greddy kit off a salvage car with AEM water meth, a whole bunch of gauges, a boost controller and an Adaptronic select ecu for $2800.... considering how cheap these cars are if I can make 275 WHP at ~6-8psi I’d say the horsepower per dollar ratio is pretty rad. Also my mom could give less of a shit if my car blows up lol.
A lot has changed since this video. My 40th anniversary is heading to rotary performance in texas. They have a piggy back now and a new redesign that can make it much more reliable and much more powerful. I have no issue dropping 30k into this car at this point to achieve this.
Dude come to Greece... 1. ECU handles the FI just fine. 2. There is a lot of room in the engine bay 3. Boost about 0.6 to 1,0 is 300+ ps without opening the 13B. Dont need more for everyday use. 4. FI is much cheaper than NA
Might not be as efficient, but what about supercharging one? Blowers tend to take up less space and roots or screw supercharger would help a lot with the notorious lack of low end Wankles have.
Is a well known rotary rebuilt shop here in Australia and they do a 14-pound boost maximum on the standard RX8. I don't know what the price is but it'd be pretty expensive
the Pettit Racing supercharger is probably the best one, my dad managed to squeeze 330whp using additional cooling mods, slightly rich afr under boost and methonal injection and the renesis version of street porting
Nice! I've also heard of many other people installing this kit, but sadly it's not as popular as turboing the car. But definiely a mod to consider. How many miles did you put since having the supercharger? Still working good?
These days people use rx8 rotors because yes, they are the highest comp, but they are also the lightest, scalloping and milling the apex seal seats will actually allow you to use normal s5/s6 3mm apex seals while having the lightest and highest comp giving a better torque figure Those shitty housings can be replaced with standard s5 ones for a full 50-60hp increase due to exhaust flow, yes you need to pull it apart to do all that but if your getting a rotary to boost and have fun in expect a rebuild, no one should get these cars not expecting one, they will break and they need money
Simple solution to all this... Don't turbo... Go NA build... Balance the engine on each Rotar then on the full assembly.. New ecu... Run it on higher RPM with new maps better cooling if you need based on your trim... New clutch and flywheel for throttle response.. Anyways the list continues on what can be done and stay NA and boost your output but you get the idea of what im getting at FI isn't the only way to boost power
Most of the information provided in this video are wrong. Use higher octane fuel and you will be able to run higher boost well to a certain extent at least and you won't be limited by the compression but rather the poor exhaust flow on the Renesis. Use MazdaEdit + Open Port cica 500$ and you can easily remap your ECU to deal just fine with all the fuel needs all the way up to 450 WHP If you are going to Turbo a rotary you should also make sure that you PREMIX + Using the MazdaEdit you can increase the oil injection rate which will yield to a more reliable rotary ( relative ) Engine space well, The RX8 is pretty tight on that however you can still do some top mounts on Left Hand Drive by moving the battery to the boot or you can do a low mount with some kind of persuasion. The rx8club forum is full of successful turbo builds
But if you change the seals to old rx7 seals with new machined rotors or simply use carbon seals, and change the housing to gslse peripheral exhaust to increase overlap & reduce heat... can it then handle 20psi of boost?
Yeah, that was funny about "And Boom!, Your engine will blow and your mom will be mad." Thanks for the insight, I just bought an Rx8 and figuring out what I can do to make it wicked. M.
It's not all that long of a shot if you have a s2 engine. It usually reeks of oil not turbo charged. with premixing that issue is ruled out. the best thing for a r3 would be a turbo. factors like space are simple if you give it some race treatment. The engine would do good for 9-11 lbs of boost. the downside is just money and skill.
Great vid, again! I have been toying with the idea of a twin screw supercharger for mine. Rotary scream with a blower whine. Sounds like a great combo to me. :D
The only realistic gain is sound. For a cai to really have an effect, you would need to put a free flowing exhaust and tune up the increased amount of air.
one of the post i was reading stated that due to the high design of the airbox on the rx8 it would lower your power then gain unlike say a civic the rotory engine is such a high tuned machine anything you do needs remapping lol
you missed probably the biggest reason next to the higher compression... the side seals are thinner on the rotors of the renesis VS 13B REW. this limits the boost due to overheating the seals and them losing their heat treatment.
This is why I feel like taking out that crappy Renesis and putting the real 13B in. Any problems with that. If you all say Engine space. Start hammering it out.
Quick question , wouldn't it be cheaper to just do an rx7 FD conversion. The shop near my house in Tampa quoted almost 10 grand to turbo the renesis versus 6,500 for a full conversion
Of course it would :) Turboing an engine that was not made to be turboe'd is way more expensive than installing an already turbocharged one, and you still have leftover money for a good tune in the end :)
Renesis is still a 13B. This engine tends to last longer than other 13b's. Only the older 12a's last longer. 13b-msp has been the most refined engine to date and can last 100k+
One major reason not to is that it adds a little turbo lag that can ruin the NA responsiveness of the 13B. Better to stick with porting or even try to track down one of those rare supercharger kits.
Detonation is caused by the intense build up of heat in the combustion chamber. You need to do the EXACT OPPOSITE of what you suggest in order to get the heat out of the chamber. This is why racing rotaries have forged housings. Housingings with a shit ton of coolant chambers are the only real efficient way to disperse the heat away from the combustion chamber.
Yusuf Abdul Basith people do this, it's called peripheral port injection. You're correct in assuming that it increases burn efficiency but it doesn't actually reduce heat build up by that much. It burns more completely but the shape of the combustion chamber is at a disadvantage just because of the way it is designed. For a better explanation watch Engineering Explained videos on it.
Jake Lamotta I already did, its called 10 mistakes new rx8 owners make, and it goes along side the Rx8 maintenance schedule video 😄 And to prove the reliability there's also the 7 things rx8 owners fear :) Hope this was useful 😊
Remove leading plugs and pull the fuse for the fuel pump. Roll the engine over for a few seconds. Then, let it sit with the plugs still out. After 10-15 min, put the plugs and fuse back in. Should fire up. Then look at the uprated starter, new ignition, and check compression.
That's a great transition. The rx8 definitely leaves a strong memory in every owner, i don't even want to think of the day i'll have to sell it :/ (hopefully i'lll manage to keep it in a glass garage as my personal collection :)
He has the AEM intake, which commonly produces 1-5 horsepower with tuning - although, without tuning it does basically nothing. You'll mainly only lose power from an intake if you keep the pipe too short so the filter is located in the engine bay sucking up hot air.
Because in my country (and majority of Europe), if you speak less than 3 languages, you are considered ignorant. And also my job requires me to speak them, to better communicate with people from other counties :)
Of course you can, if you have added a turbo, you can fit a boost gauge :) Here's a video showing you how it's done: ua-cam.com/video/0-JieFM0MHA/v-deo.html
I have an S2. It's not really any better. The things that effect the engine boost ability are pretty much the same on both. You just have better lubrication. So, still not recommended. A supercharger may work better if twin screw/roots style. Only because the boost is carried at all RPM so small gain effects the whole rev band compared to just peak power at the top end. I am actually toying with the idea of putting a supercharger on my 09.
A supercharger may help more with the low RPM torque issues, although the RX8 didn't have as bad of a torque issue as the previous rotary cars. It would make it more streetable than a turbocharged RX8, although not by much. The effect is mitigated by the wide RPM range of the Renesis, making it difficult to get a pulley ratio that provides as much benefit at lower RPMs as a supercharger would normally give. To take the most advantage of the characteristics of the rotary engine, a turbocharger would be better overall for performance. Rotaries flow A LOT, both on the intake and exhaust ends (Mazda put a surprising amount of effort into design both on the RX8, and it shows from the Renesis's 54.37% increase in power output over the last NA 13B they made); using a turbocharger fits these aspects of the engine much better. Either way will place additional strain on the engine that it wasn't designed for, in addition to the inherent strain from increased power output :)

Anybody is welcome to answer my question if they know what they're talking about. when I cold start my RX8 it makes a high whining sound and after twenty to thirty seconds it slowly goes away with a powering down sound. it's hard to explain but my car still runs fine.
Dystopic yes he said that, what a blasphemy. How dear he pronounce words they way they are written, rather than a strange variation of letters that have almost nothing to do with the word itself. Hahah just kidding man, I know its pronounced I-earn, I just mix my pronunciation sometimes cause I'm multilingual 😊
easiest way to turbo an rx8, single turbo 13b-rew swap with a renesis front cover and modified counter weight. Retains all factory electronics and no wiring changes, then tune with an adaptronic piggyback ecu.
Hey man just some help on pronouncing "iron", it is actually said like "I earn" vs "I ron". So "Iron money" would be said the same way as "I earn money". This is typical american english FYI. I got a little confused when you were talking about ports but figured it out and figured I would help with the pronunciation.

You can fix the boost limitation with a better map and a reflash on the ecu

If you are going to Turbo a rotary you should also make sure that you PREMIX + Using the MazdaEdit you can increase the oil injection rate which will yield to a more reliable rotary ( relative )
Engine space well, The RX8 is pretty tight on that however you can still do some top mounts on Left Hand Drive by moving the battery to the boot or you can do a low mount with some kind of persuasion.
The rx8club forum is full of successful turbo builds
But if you change the seals to old rx7 seals with new machined rotors or simply use carbon seals, and change the housing to gslse peripheral exhaust to increase overlap & reduce heat... can it then handle 20psi of boost?
Get supercharger for it. No need to deal with exhaust restrictions limiting the boost. Also takes care of the low end issue.
Yeah, that was funny about "And Boom!, Your engine will blow and your mom will be mad." Thanks for the insight, I just bought an Rx8 and figuring out what I can do to make it wicked. M.
It's not all that long of a shot if you have a s2 engine. It usually reeks of oil not turbo charged. with premixing that issue is ruled out. the best thing for a r3 would be a turbo. factors like space are simple if you give it some race treatment. The engine would do good for 9-11 lbs of boost. the downside is just money and skill.
Great vid, again!
I have been toying with the idea of a twin screw supercharger for mine. Rotary scream with a blower whine. Sounds like a great combo to me. :D
Thanks bro! :D I don't think my ears could handle that much orgasm xD
I just bought a 2004 RX-8, it should run good. What engine oil should I use and what gasoline should I use, Please advise. Thanks
Have a look at my channel, every question has a video about it :)
Awesome video as always man
al capone Thanks bro 😊
Aint got no turbo, but it will give u a dam good run.
Last thing I'm doing to my RX8 (years from now) is getting a 13B REW swap. Until then I'm relying on my renesis to keep me going.
what do you think of cold air intake i noticed you have one but from what i seen around on say RX8 club most times it seems to work against the car .
The only realistic gain is sound. For a cai to really have an effect, you would need to put a free flowing exhaust and tune up the increased amount of air.
one of the post i was reading stated that due to the high design of the airbox on the rx8 it would lower your power then gain unlike say a civic the rotory engine is such a high tuned machine anything you do needs remapping lol
you missed probably the biggest reason next to the higher compression... the side seals are thinner on the rotors of the renesis VS 13B REW. this limits the boost due to overheating the seals and them losing their heat treatment.
My mum gets mad even without the boom. Can I still add a turbo?
Hell yeah man, the worse thing that can happen already happened ;)
This is why I feel like taking out that crappy Renesis and putting the real 13B in. Any problems with that. If you all say Engine space. Start hammering it out.
Quick question , wouldn't it be cheaper to just do an rx7 FD conversion. The shop near my house in Tampa quoted almost 10 grand to turbo the renesis versus 6,500 for a full conversion
Of course it would :) Turboing an engine that was not made to be turboe'd is way more expensive than installing an already turbocharged one, and you still have leftover money for a good tune in the end :)
Renesis is still a 13B. This engine tends to last longer than other 13b's. Only the older 12a's last longer. 13b-msp has been the most refined engine to date and can last 100k+
Thanks for the added info Kev, It's always welcomed to improve this channel's goal :)
Kevin P renesis is the lest reliable of the 13bs what planet are you on most reliable is the 2nd series of the FC 90-91
the RHD versions of the rx8 have the problem of the steering linkages being in the way of a turbo manifold
#Merica!!!
One major reason not to is that it adds a little turbo lag that can ruin the NA responsiveness of the 13B. Better to stick with porting or even try to track down one of those rare supercharger kits.
Ceramic coat the rotor face with a thermal barrier... Keep the heat inside the chamber and not in the housing.
nice :) you think the same thing with me
that'll do jack shit to combat detonation.
Detonation is caused by the intense build up of heat in the combustion chamber. You need to do the EXACT OPPOSITE of what you suggest in order to get the heat out of the chamber. This is why racing rotaries have forged housings. Housingings with a shit ton of coolant chambers are the only real efficient way to disperse the heat away from the combustion chamber.
why not use multipoint ignition to to reduce burning time, this mean can increasing efficiency
Yusuf Abdul Basith people do this, it's called peripheral port injection. You're correct in assuming that it increases burn efficiency but it doesn't actually reduce heat build up by that much. It burns more completely but the shape of the combustion chamber is at a disadvantage just because of the way it is designed. For a better explanation watch Engineering Explained videos on it.
Everything was very well as explained, great video (:
Cyn Ozz thanks :)
can u do a video on the how to take care of the Rx-8, I think most people just call it unreliable.
Jake Lamotta I already did, its called 10 mistakes new rx8 owners make, and it goes along side the Rx8 maintenance schedule video 😄 And to prove the reliability there's also the 7 things rx8 owners fear :) Hope this was useful 😊
Driven by madness Ahh I apologise Thankyou. have u had any problems starting ur engine?
and have u did a video on how to de-flood the Rx-8 at all?
Jake Lamotta Never had that issue, but if ill have to do it, you'll see it :)
Your the man!!
Remove leading plugs and pull the fuse for the fuel pump. Roll the engine over for a few seconds. Then, let it sit with the plugs still out. After 10-15 min, put the plugs and fuse back in. Should fire up. Then look at the uprated starter, new ignition, and check compression.
Can the rx8 have an supercharger?
i just going to sale my 2003 RX-8 my next car is a mazda3 hybrid
RX-8 is nice car but consume to much, was my 5 best years driving it
That's a great transition. The rx8 definitely leaves a strong memory in every owner, i don't even want to think of the day i'll have to sell it :/ (hopefully i'lll manage to keep it in a glass garage as my personal collection :)
Lol, lubrification! Haha
How much power did you lose by removing the factory airbox?
He has the AEM intake, which commonly produces 1-5 horsepower with tuning - although, without tuning it does basically nothing. You'll mainly only lose power from an intake if you keep the pipe too short so the filter is located in the engine bay sucking up hot air.
Are you going to fix the headlights later too?
Fetii27 BABATTRO Gonna put new ones. Ill try putting the R3 ones, and do a full front end conversion :)
Love the Series 2 looks. That's why I bought one. :D
injectors and fuel pump could keep the motor from detonating
Yup, all of these problems have solutions that overcome them ( to a certain level), and make the turbo more reliable
Thank you for the lesson
My pleasure :)
I wish to buy an rx8 remove the engine and install a K20a or an SR20DET or if it fits an ej207

I did it.. It only took me 6 years and $230,000 aud:)
I have videos of it bankrupting me.
jesus christ, that's supercar money there :O
Yep 3 different work shops have taken $99,000 over the years and it never ran properly.
Now Iv'e done all the work it's running really good now:)
Sooo what I’m gathering is to swap it to a piston engine
In my country there are actually more Rx8's with 1/2jz swaps then the stock one's
I wonder why :P
So I guess the point is to just run your renesis into the ground and when it pops swap it for a 13bt or rew and then u can turbo it all u want.
Pretty much the conclusion I came to. Still rather an Rx-7 here. Was he saying lubrification?
Phoenix Rising yes I said lubrification...sometimes I mix words or misspell them because I actively speak 6 languages :)
SPCSpriggs Thats the idea 👌
Why would anyone speak 6 languages?
Because in my country (and majority of Europe), if you speak less than 3 languages, you are considered ignorant. And also my job requires me to speak them, to better communicate with people from other counties :)
make a headlight restore video your car needs it.. keep the good work going 👍👍
I'm actually planning to do a R3 front end conversion, so i will restore these ones, but later on i will replace them with the S2 ones 👌😃
What about supercharger?
what about a supercharger !!!!!! is it good???
Yup, petit racing has a bolt on kit specifically for the rx8. But it costs around 6000$
nice!
very well explained
Thanks! :D
Hay can u install a boost gauge on a 2006 rx8
Of course you can, if you have added a turbo, you can fit a boost gauge :) Here's a video showing you how it's done: ua-cam.com/video/0-JieFM0MHA/v-deo.html
So you're just saying that you should just put in a rx-7 fd engine and only then turbo it
What about a series 2 rx8?
The S2 can take it better than the S1, but mostly the same applies here too.
I have an S2. It's not really any better. The things that effect the engine boost ability are pretty much the same on both. You just have better lubrication. So, still not recommended. A supercharger may work better if twin screw/roots style. Only because the boost is carried at all RPM so small gain effects the whole rev band compared to just peak power at the top end. I am actually toying with the idea of putting a supercharger on my 09.
So why turbo change over a super charge I'm a newb at this stuff
A supercharger may help more with the low RPM torque issues, although the RX8 didn't have as bad of a torque issue as the previous rotary cars. It would make it more streetable than a turbocharged RX8, although not by much. The effect is mitigated by the wide RPM range of the Renesis, making it difficult to get a pulley ratio that provides as much benefit at lower RPMs as a supercharger would normally give. To take the most advantage of the characteristics of the rotary engine, a turbocharger would be better overall for performance. Rotaries flow A LOT, both on the intake and exhaust ends (Mazda put a surprising amount of effort into design both on the RX8, and it shows from the Renesis's 54.37% increase in power output over the last NA 13B they made); using a turbocharger fits these aspects of the engine much better. Either way will place additional strain on the engine that it wasn't designed for, in addition to the inherent strain from increased power output :)
*lubrication :)
Awesome video. 20B swap it is then XD
mrawesomelemons Will you believe if I told you that that is what write, but always manage to say lubrification. This is partly cause I speak Italian, alongside other languages, and mix words 😋
No problem mate. Being multilingual is amazing anyways! Just trying to help :)
And for that, you have a special place in my heart :P
Thx Man! Very interesting!)
Rew > Renesis fuck 400hp reliably on an "emissions rotary"......
высокая степень сжатия это неплохо, это нужно использовать но сильно степень сжатия там не поднять
So basically, you would be better off swapping the 13b Renesis for the 13b REW
Great great video I miss my rx7
Thanks! Well, you never know when you might own one again :)
what was the outro song?
I created that outro, :) ( i'm also music producer). The whole song will be uploaded once i finish it, so stay tuned :D
I found an abandoned red RX8 at my apartment, im trying to figure out who owned it to see how much it will cost. Ive seen wasps going inside the exhaust, so im prolly gonna get stung trying to fix it up
Did you fix it?
@@a48717 unfortunately the owner didnt sell it to me, they were greedy or something and scrapped it instead of selling it. and 3 years later due to the giant price jump of japanese branded used cars, any rx8 in my pricerange needs a rebuild or will need one soon, so im sadly going to finance a 350z
@@elijahstewart1333 Whats the price for a 350Z. Norway where i live has a insane state tax for cars and plus the drift/Jdm tax a semi clean S14 with 150 000km is around 22 000+ USD

@@elijahstewart1333 yeah about the same here, 350z has always been 23k USD to 30k used for clean low mileage. Since the market is so small in Norway often in the winter most cars are in the garage so few sell at that time. So the first one to post it for sale before summer decides the price. It’s freaking ridiculous. TikTok and UA-cam has made the price go insanely up recently. So all car good or bad, famous or hidden gem all are about at least 20k usd
Anybody is welcome to answer my question if they know what they're talking about. when I cold start my RX8 it makes a high whining sound and after twenty to thirty seconds it slowly goes away with a powering down sound. it's hard to explain but my car still runs fine.
Make a video, people will better understand the situation, and can give you some info about it :)
jaden tarver it's an air pump for emissions. It's not important, just annoying
What do you think about supercharging an RX8?
An rx8 can be boosted reliably
great info
Thanks! :)
1:06 what did he say? Exhaust in the what? Iron?
Dystopic yes he said that, what a blasphemy. How dear he pronounce words they way they are written, rather than a strange variation of letters that have almost nothing to do with the word itself. Hahah just kidding man, I know its pronounced I-earn, I just mix my pronunciation sometimes cause I'm multilingual 😊
It's a shame really such nice nimbleness just not enough torque rx9 coming
I agree, it could have a bit more torque especially under 6k rpm, because it feels like a Clio 1.2 before it hots 6000 Rpm :P
Sounds like you're better off swapping an FD engine into it. With the number of heathens swapping LSs into FDs they shouldn't be that hard to find.
How about SUPERcharging?
If I had an rx8, I'd most likely just go for an N/A 20b swap

A 26b
IF it requires replacing
they really are a pain. Miss my RX8 though
RpgSlayerTV They are a pain, but like bondage, there is pleasure embedded in pain 😋👌
i don't trust anyone who says lubrification
easiest way to turbo an rx8, single turbo 13b-rew swap with a renesis front cover and modified counter weight. Retains all factory electronics and no wiring changes, then tune with an adaptronic piggyback ecu.
Excuses... all cars that don't come turbo pretty much have these problems except for the oiling which is an easy solution.
Hey man just some help on pronouncing "iron", it is actually said like "I earn" vs "I ron". So "Iron money" would be said the same way as "I earn money". This is typical american english FYI. I got a little confused when you were talking about ports but figured it out and figured I would help with the pronunciation.
Also it is lubrication, not lubrification.
Thank you very much for correcting me, i always appreciate that! :)
