I took all the oem box and threw it across the fence. Made my own intake out of 3.5 inch aluminium. Used the mesh before throttle body. Coolant temps dropped 15 degrees and it goes hard...also threw the plastic over fan across the fence as well

Good Info.

Tell me u talk a lot of bs... without telling me u talk a lot of bs 🤡🥱

Don't apologize man. Your perfectly fine. What matters is you had the courage to get in front of the camera and share your experience with us about your RX8 and your ownership. It's valuable information that people like myself are seeking out cause we're either curious or want to own one. Which in my case I do want to own one someday. Cause as meticulous as I am with the maintenance on my Mazda 3 I'm pretty sure I can handle maintenance on one of these to. Cause the only thing that truly makes it different is the fact that it utilizes a Rotery engine as opposed to a regular piston engine. Otherwise everything else around the engine is still stuff that's used on piston engines. It still sorta functions like a piston engine in terms of the combustion process. It just has a different way of going about it but still the same result. But good God I really want one. I love they're unique shape, their unique sound. I have never driven one unfortunately but hopefully in the future I can have the opportunity to drive one and own one.

That seems like a lot of oil for a small amount of fuel.

Engine Oil isn’t supposed to smell good I would imagine

Is this for a 4 port or 6 port?

My 04 sp does not have that valve. Is it hp only?

I don't think my car has that box and valve controlled by the vacuum line. Pretty sure I just have that mesh duct leading to the air box and that's it. Interesting..

What offset do you have ??

So when I had my first RX8 years ago, I never Premixed and only did frequent oil changes with conventional oils. This time after years of researching and looking into parts and modifications and what not, I'm going to go with putting on the Sohn Adaptor to change where there Oil Metering pump pulls oil from. I haven't found anyone talking about oil from the Separated system getting into the Oil Sump. Because adding a Sohn adaptor then separates them completely. You do have Oil from the pan being sent through the Eccentric shaft for bearings and inside the rotors, but in order for the Oil from the Sohn system through the injectors to get into the regular engine oil, you'd have to have a bad seal. The oil metering system doesn't have an oil return line as far as I'm aware of, because the Oil Metering system only squirted oil at certain instances in the rev range, so it isn't a constant pressure that would warrant a return line. So I'd see the benefit of having Clean, Colder oil from the Sohn Adaptor reservoir being used rather than Hot and dirty oil from the oil pan being put into the rotor housing. I'd also go as far to say, this is the application that would work best for the Idemitsu Rotary Oil, because it's specifically formulated, clear and a bit more viscos. The great thing about separating the oil metering with a Sohn Adaptor, is that you can, worry free, use whatever synthetic you'd like in the engine oil. Though, like you said, some synthetics are designed to burn cleaner. I've had lengthy conversations with the Tech Team over at Royal Purple about using their oil in a Rotary application, and they've assured me that using it in a stock application like the RX8 is completely fine. They've had thorough studying via Racing applications using their products and had great success. So I believe you when you said, It burnt clean. :) Anyways, we're constantly learning about how to make these cars better all the time. And the best we can do is research and see what others have done and make our own best judgments. I appreciate your perspective!! Keep up the great work in your hobby!!

I really appreciate your video here. My two cents, is that I was considering having a small gas can in the trunk to shake up pre-mix in at the pump. So that a thorough mixture went into the gas tank and not just pour and hope the gas from the pump mixes it well enough in the tank. And you're showing what happens when this settles in the gas tank. We need a good enough Gas/Premix Ratio being sucked up by the gas pump sock/inlet. If we're sucking up too much Premix and then just gas the rest of the time, then we aren't getting that benefit of sipping Pre-mix as we use gas, like people think they're getting. Which 2stroke oil stays suspended in gas? That's the question!

wow, pretty cool actually. I do premix, and I also raised the oil injection, so my sparkplugs really last for not that long, but knowing this, hell yeah it's an improvement.

Thank you for for being so HUMBLE and HONEST, and for shining some LIGHT on all of the DARKNESS that many stupid ignorant people have been casting on this extremely underrated sportscar! 💡💡

Brand of that hood?

Fantastic video! I appreciate the honesty and it's good to have a long time review of the Rx8.

So you’ve had the rx8 around to decades and never had issued with the rotary?

This is why you pour the oil in first then pump gas. You really want it to mix well. It looked to me like the Amsoil actually mixed better. That layer on the bottom with the idemitsu is NOT what you want, too much oil has the effect of leaning out your fuel mixture. If you’re going to use it make sure you pump fuel after to help mix it better. I always left my factory OMP on mine and used a cat safe 2 stroke oil. Never had an issue. Honestly I’d stick with the Amsoil given it’s cheaper and frankly probably as good or better oil.

To anyone considering buying this car or any rotary engine car: DONT!

Dose it matter if there like this mine is the same. Also is it easy to replace them

Use a strong shop vac. It pulls them straight. Then use a small flat head and finish them off. A lot easier than using tweezers, brother. Cheers

Castrol GTX High mileage. Iv been using it for years on all of my Mazdas. RX8 has 121k on original engine and still runs like new. (gutted cat) Cheap 2 stroke oil in the fuel. 2 or 3 gulps per tank. Good to go! Too many people over think it. I laugh at the RX owners that think you need to run that snake oil Idashitzu oil. lol Just buy a low ash oil. 35years of building 2 stroke motocross bikes, jet-skis and V6 Mercury race outboards.

Talk talk and more talk

Back in the days, Mazda gave a race engine to Idemitsu and asked the company to make engine oil and Premix oil for that very type of engine! You can't go wrong with Idemitsu. I drive an Rx8. I use Idemitsu Premix for the Sohn kit (injection into the combustion chambers), I use idemitsu engine oil for the engine/sump and I use Idemitsu gear oil for the gearbox and diff. Premix wise, I either use Idemitsu Premix or Pettit Racing Protek-R. My ECU has been reflashed so that my OMP has increased oil dispense rates and I Premix. Both the fuel pump and the catalytic converter are original, 17 years and 63,000 miles. No issues whatsoever.

So grateful for you sharing your knowledge and experience. One of these maintenance videos a month helps everyone so much more than the fluff (mostly stats and habits) mainstream channels pump out. Keep it up 👍

I dont know if you know but the oil pump witch is putting the oil in the injector s that is not a pump witch is pumping constant it is a Load activete pump it is puting out drops of oil tot galons And it is also not burnig instantly it is first doing lubrication to the motor side walls And two stroke oil in the gastank i use 1 on 450liters of gas it is to protect the middel of the apex seals Have fun driving your rx8

You should probably see what the entire stock setup is... It has the same Ls, that you claim would be 'restrictive'. The airbox isn't everything.

Our rotary lord and savior strikes again. Just finished three weeks of six-day 10.5 hour shifts as a delivery driver and this is what I wake up to. Thanks for the early Christmas present! ¡Feliz Navidad!

Interesting vid! Thank you for sharing. I would be curious for a follow-up video to know if separation occurs over the course of a week or two to simulate how it would sit in the gas tank for an extended period of time

Brother please I need a answer I got the same problem I need to replace those valves but my questions is is that why my car. Dies randosmly everytime I get into the expressway I feel I go slow and then randomly dies on me ..

🤔interesting... I didn't know what other option to use besides IDEMITSU. But I think I'll see what other substance has for a better premix and even injection into the engine... I'm starting to understand my RX8 and this helps me a lot, thank you !

Wanna sell the rx8?

You don't know what you're talking about! I drove my RX8 over a hundred thousand million miles and never changed the oil one time and it still runs perfectly. Haha just kidding, those forum debates are hilarious to read. Thanks for another great video!

I agree with a lot said here but one thing you might want a better understanding is how much vacuum and suction an engine has.. ram intakes will absolutely not help at all as the amount of force needed to pressurize air in order for it to overcome the natural vacuum pressure an engine creates is exponentially greater than any amount of air that could be forced into a car just from driving. The best two things an intake can do is get the coldest air possible with as little restriction as possible. They certainly do have the vacuum pressure to suck air through even small pipes.

Basically change your oil regularly and don't go lower than 10w (this was said by many rotary shops due to bearing failures) just change it regularly and don't let your oil degrade with time or heat cycles, premix if you want, but understand that premixing = spirited driving / race track and 93 gas or 98 in Europe.

A thinner oil flows easier and requires less power from the engine to flow it. Despite the fact that the rotary does not have a crankshaft exposed to the oil pan, it still does have an oil pump and this pump still does require a degree of power to turn. There is also oil flowing into the rotors through the eccentric shaft. A thinner oil will flow through the rotors much easier and faster. The oil is the only way the rotors themselves are cooled. Unlike other engines, oil does provide cooling to the rotary. Almost as much as the coolant. The other thing to think about on the rotary is how well a thinner oil can flow through the very small nozzles of the oil metering system. 5k+ miles, use a good synthetic such as Amsoil or Royal Purple and be done with it. Also a good idea to run premium gas when you premix as it lowers the octane of the gas as well. I do 4-6oz per tank 2 stroke lucas semi sythetic sold at Oreilly or Autozone near me.

I think RAD Potential in his premix video mentions how even the Idemitsu stuff tends to settle out when left sitting in the gas tank. Any insight on that front? Did you ever have a situation where you left the 8 sitting not on empty with premix and if so what were the results? Thanks much for all you're doing this channel is becoming an RX-8 starter guide/reference encyclopedia and I hope everyone stays orderly and respectful in the comments.

Heat is the #1 enemy of this engine...besides haters 🤣🤣🤣

Thanks for your feedback, what do you recommend after a rebuild? use a 5w20 anyway ?

what products did you use to clean your engine bay? Looks great

That damper opens at 5.5k, and the length is tuned. The resonator is for engine drone, no effect on power.

I don’t have an RX8, but from someone who has been mixing 2-stroke fuel for my whole life… You can’t take any 2-stroke oil dump it into a tank of gasoline and hope it will mix. Ideally you want to mix a batch in a Jerry can by sealing the lid tight and agitating WELL. That allows top ups without messing up the ratio. To mix in tank at a gas station, I’d recommend mixing the total required oil in a 1 gallon Jerry can, mix well, dump in tank, then top up with the correct amount of fuel.

Yes,yes,yes, finally someone with sume good advice, I've said it for years the more you expect, the less reliable it gets. These cars are built for carrying speed in to corners, there Not the fastest from A - B ,or from a standard start, but thay have endurance. Let the force flow through your body

Had my 05 since 2005 only owner

Premix vid ETA?

Well, technically speaking, the stock box and ducting IS CAI. But I get what u mean. Amazing how much design and research went into the factory unit.

I think it is a very misunderstood car from this video. It's obvious that it can be more reliable than any piston engine with the proper care. I think the problem came up because it was the first mass market RX sports car. Really they should always have been aimed at the supercar market.

I feel heard ;) 14 years with a 2008 40th anniversary, driven summers and winters up North in Montréal, Canada, and have the same feeling about the car. And this after having leased a 2005 model prior to that. No pre-mix, only used non-synthetic oil, and drive it as it should be driven at every chance I get. Only worry is rust as I neglected it in the later years, but it started faintly in the rear wheel wells after 12 years. Otherwise, this has been my most reliable car (but DO read the manual and stick to the maintenance calendar!). I much enjoyed your video.

You never replace the standard rx8 airbox mazda spent millions of dollars in research and development there is no gains to be had by replacing it best thing to do is replace standard panel filter with a better flowing one facts

I currently have a FC RX-7, but recently have been contemplating selling it and getting a RX8 R3. It’s basically a FC, but better in every way.😭
