@@1IRoyle I'm in the same boat. looking to buy my first car, and I have a huge passion for miatas and the rx8. I don't wanna fuck it up because I'm not made of money lol
No, I have tried to Turbo my new 2010 GT(R3 in the USA) for 10 years. I have had 3 work shops take on average 30K usd each to do it and always failed. I bought 2 x new crate motors and they both lasted less than 3000km. I have spent over 200K usd all together so far and have just ordered all new rotors, irons and rotor housings... This time I am checking all the wiring by all the workshops, removing my over kill 600hp fuel pump and going back to stock fuel lines and injectors. Plus running max 6psi instead of 22psi when it made 266kw atw before.
@@locky2562 I just added up the receipts and that what it costs when you completely destroy the engine lots of times plus work shops over charging for shit work. The 200k includes the price of the car new when I bought it at $46kusd. (yes they cost way more here in Australia)
@@locky2562 Yes, it pisses me off I let it get this far. But it happened over 12 years and the work shops just asked for 1k here and there and it just adds up. I got into debt trying to pay for it. Then it would blow up and they would blame the fuel or something. So I tried another then another workshop before giving up and completely redoing/designing everything myself.. Australian workshops don't give a fuck about anything but the money u pay. So since that post a year ago I have change more things and make an easy 200kw atw (double stock, they only make 100kw atw) at a reliable 8-10psi on 98 aus fuel. Easy to make way more on E85 but there's none where I live now. But I have learned other things fail if you run much over 200kw atw like the prop shaft uni joints(they are tiny) and the gear box possibly (I'm not sure if one of the work shops abused my original one) I bought a new one and it's fine so far.
I had the same happen to me also. I made sure to get an all aluminum one so I wouldn't have that problem again. I chose the one from CSF and installed myself.
Either one will do well on an rx8. Super really helps to even out the power band, makes up for the low end lacking power and holds good up to the 7-8k range. But due to the really high rpm of the rx8 they need to be good quality to hold up and the last 1k of rpm is lacking usually. Turbo provides a big boost to the already best part of the Rev range. 5k+ and allows you to still maintain decent mpg for cruising while the super will chug gas all the time.
@@guidomista8448 I really doubt you will find a kit for it so I'm 95% sure that you'll have to build your own kit. www.vividracing.com/-p-150706653.html?gclid=EAIaIQobChMI_fa7uNOP4QIVzbjACh2CCAn6EAQYASABEgI9UPD_BwE This will handle 18k rpm regularly so as long as your pulleys are at a 2:1 ratio or less it will handle the rx8's 9k redline.
Here is the problem with a supercharger. As revs increase, your resistance increases too and your net gain will be pretty low at the top end in favour for instant response (the car will basically feel like it's N/A but with a bigger engine) and low end/midrange torgue. For this reason it's the unwritten rule that you supercharge low/mid range revving engines and turbocharge high revving engines as the turbo doesn't impose that resistance when revved up. Now, given the fact that rotary engines are the highest revving engines on the planet, it stands to reason that the turbo is what you should be looking at if you're going blown. Furthermore, a rotary spools a turbo way WAY faster than a cylinder engine, so you could basically go for the same HP a supercharger will get you and also have almost non existent lag and spool time. This is because the rotary dumps so much fuel and stuff out the back that the turbo will spool much much quicker for any given HP (as compared to cylinder engines) Hence supercharging a rotary is basically a big no no.

The only thing stopping me from wanting to turbo an rx8 is that it won't pass insoection due to the ecu having to be scanned. All the kits I see for sale are stand alone. (esril turbo kit)
@@wethenorth4378 still crazy, where I live no one ever inspects the ECU during the regular periodic inspection. They do it only during "extra-ordinary" inspections, that happens only in case of severe violations of street rules.
@@tommythebiker3081 Over here all they do is see if you have a check engine light on RX8's. Had mine removed and it passes inspection with a decat every single year. Fun fact: on older rotaries they don't even do that and you don't even have to do an emissions test. The test guy didnt believe me so I let him try it. Apparently I nearly fucked up his diagnosis equipment with 700 grams per kilometer of CO2. And it's legal. At least over here in the Netherlands.
And LPG will help it stay daily and without a hint of carbon deposit in the engine.. It's possibly the only engine that doesn't get fatigue from burning LPG..Set it to LPG up to 4.5k rpm and you have a perfect daily..two of my friends have LPG rx8s since they rebuilt them and they're both well past 150k miles with almost stockish compression..
My Rx-8 Radio's LCD and Fan aren't working, past owner fucked it. Your past video on the adapter install was good, but it only got me so far to fixing the the radio and such. Could you help me out? Also, I checked the rx8 forums, it was just lacking any video with clear pictures on how to set up the connectors and stuff.
Have you checked the faceplate? It seems to be a common problem, i have it right now, the faceplate controls the radio and the AC, the screws that hold it onto the actual radio either get lose or come off and you lose all function. Does the lights on the radio turn on at all?
can someone tell me an average price range of how much the whole build costs on a budget? i wanna build a car this summer with 12-15k but don’t know what would fit that budget that’s RWD.
Could adding a turbo (let's say 350 hp to the wheels) help the car in 6th gear to push 260+km/h? Right now it just cruises at ~230 km/h in 6th gear and it takes a while to get there
also with turboing a renesis, from what I understand its not the apex seals that are mainly the problem (even though these are what ultimately break) its the fact that the exhaust ports on the renesis are angled weird to keep oil in for modern emissions. Of course street porting would help out immensely but the fragile graphite laden seals are going to suffer from the uneven surface of the rotor housing. Now.... say if someone were to make custom cnc'ed housings that allowed for a built in peripheral port with a supporting bridge in the middle for the apex seal I couldnt see why this wont work better? You can only shove so much boost in a renesis before stuff goes boom? I am probably wrong but the theory and mechanics behind a rotary made me harder than a diamond
You are absolutely right. But a bridge/peripheral port will always cause your seals to wear quicker as the Exhaust leaves right by it instead of further inwards on the rotors face.
you are totally wrong. go open few book about renesis before posting. port side is to reduce co2 aka over lap of ports better to say control timing and....
If you can't install the turbo kit yourself, then you have no business messing around with anything turbo that didn't come turbocharged from the factory.
Tbh, turbocharging the rx8 is definitely not a good idea to do with a stock renesis. If streetported maybe, but the engine life will still decrease dramatically, and you can only do this with a renesis 20k miles or lower. You could run 7lbs of boost and maybe get 80k out of your motor if you’re lucky. the amount of money you would spend to turbo the rx8 properly... mine as well get a REW swap.
Looking at 5000 to 7000 dollars plus a possible engine rebuild for a 30 - 120 hp gain. Doesn’t seem worth it to me. If you want straight line speed you better off with a piston powered car. The RX8 is all about the chassis and handling, not speed and power. If you want a fast, cheap turbo powered car work on a Honda.
@@TexasVexes yup, that's the beauty of Mazda. Car is set up nearly perfect from factory. Dont need to add too many mods. However, most the ones done on this channel will help your car last longer if you daily one like I do.
Just picked up a 40th edition with 70k miles. Just had plugs/coils/wires done. Radiator fluid and diff fluid changed. Keeping her locked up for the weekends ;)
Can REW can get more power than the RENESIS? INCORRECT, the the naturally aspirated RENESIS makes almost as much power as the REW with 2 turbos (235 HP vs 255 HP). The only reason people like the RX7s more is because they are purists that think nothing can ever live up to it. Can we please put this myth behind us?
At that time, in Japan, there was a "gentleman agreement" in order to limit cars to about 250 HP. Due to that, the RX-7 peak power was declared to be 255 HP, but in reality the FD was able to surpass 280 HP. Still, IMO it's a relatively small power difference considering that the RX-8 is naturally aspirated and the RX-7 has a twin turbo, as you say.
Pretty inaccurate I have to say. Also, it has nothing to do with a gentlemans agreement. It's the *law* in Japan. You weren't allowed to make more than 280bhp. So what they did is they made engines that could do 400+ but then limited them 280. With tuner culture in Japan, everybody knew what the deal was anyhow. You get your car, swap a marginal amount of parts and voila: 350-400 bhp. Some say that this law is exactlty what led to the tunerculture as we know it today. The later models of the RX7 did indeed do that maximum number of 280bhp, and it's a widely known fact that if you simply decat it, fixed an intercooler and did a remap, you'd be sitting at 350bhp+. In fact, a RX7 with a stock twinturbine (which is sequential, not parallel, so only 1 works at any given time) can do 400 bhp+ if tuned correctly. Also, the FD makes double the torgue coming out of the factory. So while the bhp figures may be close, it will shit all over the RX8 like it's clubbing baby seals when it comes to a 0-60 time, for instance. That said, if you'd N/A the fd's 13B and ported it, it would come rather close to the renesis output. Now if you were to have peripheral ports on that sucker, it would do the same as the renesis engine with the added benefit of being far more reliable. The Renesis engine is pretty much at it's peak powerfigure out of the factory, you can't really make a lot more power out of them other than simply increasing the revs. So no, we cannot put this myth behind us, I'm sorry. (And let's be clear, I have an RX8PP and an FD, I think I know what I'm talking about)
Rx8 lovers attention please. The two ECU blue and ultimate are the worst off . Newclearbombs. The worst set up for turborenesis. An easy way to blowoff fast and easy the greddy kit as it is. All the other parts of greddy kit are excellent. I mean turbine!, intecooller aki everyhing else. Turbine is the best if you uograde her to 25g and the best thing is that you can repair her any time.
I think you are wildly underestimating the costs of that. I'm in the proces of having one built for my FD and I cry everytime I think about how much it cost me. There. I'm now crying.
@@Flyingdutchy33 i am lol. I looked at a few options from a Midwest shop thats known for it. His prices for different 3 rotor builds are all for the fd and at the bare minimum it costs 35k. I found out that the rx8 is the hardest to 20b swap and costs a bare minimum of about 48k
@@jacobmincks1529 There ya go then. The way forward with an RX8 is very, very simple: Make it as light as you possibly can and raise the rev limit. That's really all you can do. That said, I'm having a blast in my RX8 despite the low power figures. Its a cornering car anyhow.
@@Flyingdutchy33 for the price its a great car for high speed cornering. Thats what makes it so competitive on the track. It gets killed on straights though. Im looking into my first rotary car. Ive looked at all the hp/torque for the 1st 2nd and 3rd gen rx7 and also rx8. Ive also considered the cost of the cars. And mod potential. Id love an fd. On my cost saver options i like the sa22c/fb or the rx8. Fd is goals though.
been considering this for a while now.. always had your original video on turbo rx8 at the back of my mind.. could probably get this done for 2k euros, always felt like my rx8 lacks low range power.. Im in a bit of a pickle
Youre probably not going to pickup any Power below 3500 to 4000 rpm because rotarys need quiet a big Turbo to make good Power and those need time to spool up. But if youre engine is healthy and you know how to get it done it is going to be lots of fun.
It's a matter of costs and hassle. Good RX-7's engines are expensive, there is not a single motor mount that corresponds, the clearance from the chassis and the firewall is totally different, etc. Putting it short, a turbo kit it's kinda a "plug and play" mod; a REW swap, NO.
Easiest way is to buy used lotus elise or opel (vaxwell) speedster, you will have faster and better on corners car. In uk prices starting from about £8000. And this cars have good MPG too. RX8 is good only if you buy this car with about 40000-50000 miles on odometer, for about £1500-2000. For 6,5 second car is worth this. But if you rebuilt this engine plus make tuning and later you need sell this car , you will never this money back. This is my personal opinion.
if you live in uk : all UK rebuilt engines failed in 12k mile due to monkey ratchets and lack of proper rotary escapist. all of them learn monkey ratcheting in drive way ! rx8 engine is not much bad by itself what make it bad is lake of knowledge otherwise every engine can/ will failed.

The rules very state by state. If you are driving a classic vehicle. The rules are very different.@@tommythebiker3081
@@tommythebiker3081 Over here all they do is see if you have a check engine light on RX8's. Had mine removed and it passes inspection with a decat every single year.
Fun fact: on older rotaries they don't even do that and you don't even have to do an emissions test. The test guy didnt believe me so I let him try it. Apparently I nearly fucked up his diagnosis equipment with 700 grams per kilometer of CO2. And it's legal. At least over here in the Netherlands.
Premixing will save your compression and seals
and false reading on compress number too ! thats why when they want to sell a car they dumped heavy permix like 600cc in tank to increase numbers
And LPG will help it stay daily and without a hint of carbon deposit in the engine.. It's possibly the only engine that doesn't get fatigue from burning LPG..Set it to LPG up to 4.5k rpm and you have a perfect daily..two of my friends have LPG rx8s since they rebuilt them and they're both well past 150k miles with almost stockish compression..
Can you do the same Video just with the 13B Engine from the Rx7? @Driven By Madness
My Rx-8 Radio's LCD and Fan aren't working, past owner fucked it. Your past video on the adapter install was good, but it only got me so far to fixing the the radio and such. Could you help me out? Also, I checked the rx8 forums, it was just lacking any video with clear pictures on how to set up the connectors and stuff.
Have you checked the faceplate? It seems to be a common problem, i have it right now, the faceplate controls the radio and the AC, the screws that hold it onto the actual radio either get lose or come off and you lose all function. Does the lights on the radio turn on at all?
Rob Rx8 the lights work fine. It’s just the fans and LCD panel in mine that aren’t working.
can someone tell me an average price range of how much the whole build costs on a budget? i wanna build a car this summer with 12-15k but don’t know what would fit that budget that’s RWD.
Bmw 335i is your best bet.
Nowww to find a used turbo! The hunt begins..
How can I ship my car to u to turbo charge it?
What about the fuel economy before and after

Im looking at doing a FD swap into my 8 -been quoted 20k
Pointless 😂😂😂😂 Just buy an RX7 ffs
Could adding a turbo (let's say 350 hp to the wheels) help the car in 6th gear to push 260+km/h? Right now it just cruises at ~230 km/h in 6th gear and it takes a while to get there
Its called down shifts lol
@@mmjnice97 free power!
Adding a turbo won't increase a top speed. That has to do with diff gear ratio.
@@nivededmore power more top end speed
one of your best videos
Thank you!
2:35 who knows the owner of this car?
Milos your in Texas?
also with turboing a renesis, from what I understand its not the apex seals that are mainly the problem (even though these are what ultimately break) its the fact that the exhaust ports on the renesis are angled weird to keep oil in for modern emissions. Of course street porting would help out immensely but the fragile graphite laden seals are going to suffer from the uneven surface of the rotor housing. Now.... say if someone were to make custom cnc'ed housings that allowed for a built in peripheral port with a supporting bridge in the middle for the apex seal I couldnt see why this wont work better? You can only shove so much boost in a renesis before stuff goes boom? I am probably wrong but the theory and mechanics behind a rotary made me harder than a diamond
Big porting on the exhaust port is a solution and it's better than the stock ports for coolant temp.
You are absolutely right. But a bridge/peripheral port will always cause your seals to wear quicker as the Exhaust leaves right by it instead of further inwards on the rotors face.
@@hillbill3502 i just do and recommand a large Street porting, nothing other.
you are totally wrong.
go open few book about renesis before posting.
port side is to reduce co2 aka over lap of ports better to say control timing and....
@@GRFX19 where are you located ? in uk ?
Thx Man!)
If you can't install the turbo kit yourself, then you have no business messing around with anything turbo that didn't come turbocharged from the factory.
You don't even need to know how car moves to do it, lol
Texas rotary experts 🤣🤣🤣
How much does it cost to install by mechanic
Did you not watch the video, this is clearly stated in the viDeo.
2k for kit
3k for install plus the cost for tune (+/-)
Its worth it if you know how to do it and if you dont have money for an RX7
The good rx7 models are way more expensive then the best rx8 (in europe at least)
Try supercharger
Nitrous makes more sense. 55 shot gives off the line speed with little reliability problems. Turbos still ned to spool up and are too hot
Well, spooling the turbo up with a rotary is not really a problem. It spools up way faster then in a piston engine.
Save the spray for the return trip
Tbh, turbocharging the rx8 is definitely not a good idea to do with a stock renesis. If streetported maybe, but the engine life will still decrease dramatically, and you can only do this with a renesis 20k miles or lower. You could run 7lbs of boost and maybe get 80k out of your motor if you’re lucky. the amount of money you would spend to turbo the rx8 properly... mine as well get a REW swap.
Good video, bud
Looking at 5000 to 7000 dollars plus a possible engine rebuild for a 30 - 120 hp gain. Doesn’t seem worth it to me. If you want straight line speed you better off with a piston powered car. The RX8 is all about the chassis and handling, not speed and power. If you want a fast, cheap turbo powered car work on a Honda.
Exactly. Plus the way I look at it is, I don’t need to kill myself or get speeding tickets. Rx8 is plenty by itself 🙂
@@TexasVexes yup, that's the beauty of Mazda. Car is set up nearly perfect from factory. Dont need to add too many mods. However, most the ones done on this channel will help your car last longer if you daily one like I do.

Can REW can get more power than the RENESIS? INCORRECT, the the naturally aspirated RENESIS makes almost as much power as the REW with 2 turbos (235 HP vs 255 HP). The only reason people like the RX7s more is because they are purists that think nothing can ever live up to it. Can we please put this myth behind us?
At that time, in Japan, there was a "gentleman agreement" in order to limit cars to about 250 HP.
Due to that, the RX-7 peak power was declared to be 255 HP, but in reality the FD was able to surpass 280 HP.
Still, IMO it's a relatively small power difference considering that the RX-8 is naturally aspirated and the RX-7 has a twin turbo, as you say.
Also just because the engine can make more power doesn’t mean much if the car is heavier.
Pretty inaccurate I have to say. Also, it has nothing to do with a gentlemans agreement. It's the *law* in Japan. You weren't allowed to make more than 280bhp. So what they did is they made engines that could do 400+ but then limited them 280. With tuner culture in Japan, everybody knew what the deal was anyhow. You get your car, swap a marginal amount of parts and voila: 350-400 bhp. Some say that this law is exactlty what led to the tunerculture as we know it today.
The later models of the RX7 did indeed do that maximum number of 280bhp, and it's a widely known fact that if you simply decat it, fixed an intercooler and did a remap, you'd be sitting at 350bhp+. In fact, a RX7 with a stock twinturbine (which is sequential, not parallel, so only 1 works at any given time) can do 400 bhp+ if tuned correctly. Also, the FD makes double the torgue coming out of the factory. So while the bhp figures may be close, it will shit all over the RX8 like it's clubbing baby seals when it comes to a 0-60 time, for instance.
That said, if you'd N/A the fd's 13B and ported it, it would come rather close to the renesis output. Now if you were to have peripheral ports on that sucker, it would do the same as the renesis engine with the added benefit of being far more reliable. The Renesis engine is pretty much at it's peak powerfigure out of the factory, you can't really make a lot more power out of them other than simply increasing the revs.
So no, we cannot put this myth behind us, I'm sorry.
(And let's be clear, I have an RX8PP and an FD, I think I know what I'm talking about)
Flyingdutchy33 I thought PPing your engine gives you big power, but your power band gets moved up and it doesn’t last as long
At the end of the day no it's not...do it once and do it right...rew swap it
Rx8 lovers attention please. The two ECU blue and ultimate are the worst off . Newclearbombs. The worst set up for turborenesis. An easy way to blowoff fast and easy the greddy kit as it is. All the other parts of greddy kit are excellent. I mean turbine!, intecooller aki everyhing else. Turbine is the best if you uograde her to 25g and the best thing is that you can repair her any time.
factory ecu retune ?
Or just double the price and get a 20b. Depending on everyone's location
I think you are wildly underestimating the costs of that. I'm in the proces of having one built for my FD and I cry everytime I think about how much it cost me. There. I'm now crying.
@@Flyingdutchy33 i am lol. I looked at a few options from a Midwest shop thats known for it. His prices for different 3 rotor builds are all for the fd and at the bare minimum it costs 35k. I found out that the rx8 is the hardest to 20b swap and costs a bare minimum of about 48k
@@jacobmincks1529 There ya go then. The way forward with an RX8 is very, very simple: Make it as light as you possibly can and raise the rev limit. That's really all you can do.
That said, I'm having a blast in my RX8 despite the low power figures. Its a cornering car anyhow.
@@Flyingdutchy33 for the price its a great car for high speed cornering. Thats what makes it so competitive on the track. It gets killed on straights though. Im looking into my first rotary car. Ive looked at all the hp/torque for the 1st 2nd and 3rd gen rx7 and also rx8. Ive also considered the cost of the cars. And mod potential. Id love an fd. On my cost saver options i like the sa22c/fb or the rx8. Fd is goals though.
@@jacobmincks1529 How about an FC then? Over here they're very reasonably priced.
remember if you know what you are doing :D
Man wtf.
Why dont u tell people they need a rebuild with better seals and much more before?
For those worried about emissions…. Why do you drive a rotary 🤣
been considering this for a while now.. always had your original video on turbo rx8 at the back of my mind.. could probably get this done for 2k euros, always felt like my rx8 lacks low range power.. Im in a bit of a pickle
Youre probably not going to pickup any Power below 3500 to 4000 rpm because rotarys need quiet a big Turbo to make good Power and those need time to spool up. But if youre engine is healthy and you know how to get it done it is going to be lots of fun.
Wouldn't you want to go with a supercharger instead?
Twin turbo?
I've got a turbo RX8 and omg it's so much fun!!
Managed to go through the entire video without giving any information... All he said was vauge generic shit.
Nice
Thanks 😊
Damn I thought they came turbo
Pretty sure the Rx-7 Fd does
I just want this comment to be noticed
Uhmmm.... Everybody knows that the rx7 engine is better, stronger and more reliable. This isn't even up for debate.
It's a matter of costs and hassle. Good RX-7's engines are expensive, there is not a single motor mount that corresponds, the clearance from the chassis and the firewall is totally different, etc.
Putting it short, a turbo kit it's kinda a "plug and play" mod; a REW swap, NO.
@@tommythebiker3081 What it boils down to: If you want turbo, get it right from the get go and forget the rx8.
It's not better. The Renesis HP makes 220+ bhp N/A, it took the 13B some boost to make 252, later 276 bhp. Renesis is much more refined.
@@Duskconqueror Son, ask any rotary builder why you are wrong.
The 13B REW engine is much more reliable.
how said ? better loll
Nice vid... But for future ref it's pronounced... Jee Reddee..
Thanks! What word exactly?
Easiest way is to buy used lotus elise or opel (vaxwell) speedster, you will have faster and better on corners car. In uk prices starting from about £8000. And this cars have good MPG too. RX8 is good only if you buy this car with about 40000-50000 miles on odometer, for about £1500-2000. For 6,5 second car is worth this. But if you rebuilt this engine plus make tuning and later you need sell this car , you will never this money back. This is my personal opinion.
best way go buy a bike lolll
This is just regular information out there. You basically repeating information that has been available since 2006. Not a good video.
Take an engine that is fragile and has a reputation for being unreliable in normally aspirated form, and add a turbo. Recipe for a disaster...
Rew swap is the way to go
downgrading + too much modification.
changing thicker apex seals is way to go
Not best info rx8 engine is as reliable as a rx7 turbo mmmmmmmmmmmmmm
That was funny
No man
Man, just k swap that junk lol
Woah woah stop the disrespect 😤 brap brap all day
You turbo it and u r ready for big trouble...
Rew rx8
Not worth it
What a waste of money.
if you live in uk : all UK rebuilt engines failed in 12k mile due to monkey ratchets and lack of proper rotary escapist.
all of them learn monkey ratcheting in drive way !
rx8 engine is not much bad by itself what make it bad is lake of knowledge otherwise every engine can/ will failed.
