Can rotary engines be reliable?
Well, in this episode, Gels attempts to extend the life of his 13b powered Dorito machine. By installing the SOHN adaptor, the engine can now take advantage of all the improvements synthetic oil gives. Hopefully the RX-8 will survive what we have coming for it with help of this improvement.

When you unplug a battery on these, you have to : 1. Turn it on & off a few times for the DSC light to disappear; 2. Fully turn the steering wheel each way until lock. Keep doing the above until it goes 👌🤣

[@chrisgoebel9762]

What he said^

[@AlbertoGomezSE3P]

Or after connecting back the battery just turn on the ignition without turning on the car, stomp on the brake pedal about twenty times til you see the needle on the oil pressure do a full sweep and back, then turn on the car and turn the steering wheel all the way to the left and all the way to the right and that will make the DSC light go away and stop flashing. This procedure is for the ecu to relearn without having to drive it for several miles.

[@th3ch33t]

You really only need to turn it lock to lock, turn it off, and turn it back on. This is based on my own experience with the RX8 I currently own.

[@c.b.6350]

My rx8 does not have DSC. the brake pedal thing is false. No need to do those things. But the car does need to relearn fuel trims.

Good video. I love the RX8, I have one. Disconnecting the battery will cause the DSC and traction control lights to come on. Reset DSC by turning the steering from lock to lock. The T/C will reset itself after a couple of starts. Look forward to seeing the rest of the build. 👍🏻

[@danielbystrika5611]

I recommend an lrb aluminum undertray. Also water temp, oil temp, oil pressure gauges

[@nielszonneveld796]

Just a heads up if you inhook the battery it "reboots" the ECU so let it idle for about 10 min so it can relearn AF value's. as for the dsc and traction turn your steering wheel all the way to the left then all the way to the right and it should turn off the dsc light, turn the car off and back on and the traction light should be off now too. (Yes you'll have to do this everytime you unhook your battery).

[@justink4636]

When rebuilding engine, widen Rx8 rotor apex seal slots to fit the Rx7’s 3mm unbreakable seals and the respective corner seals and any other seals to fit the new 3mm apex seals setup... use the stronger 3mm apex seals instead of the stock Rx8’s 2mm seals. More reliable and when the time comes to add boost.. your Apex seals would be ready to handle it. Make sure to get highly accurate machine shop to modify Rotors for the extra 1mm. Or some guys use the Rx7 Rotors instead and modify them to fit the MSP exhaust scrapping seal which is there to clean the exhaust port on the side plate housings on the Rx8.

[@MrDAllen1124]

Not sure if it's been suggested, but a couple things I've heard that you can do to increase reliability and decrease friction on moving parts in the engine are 1) WPC treatment, and 2) cryo treatment. Both of these procedures change the structure of the metal at a molecular level to essentially make it stronger, more durable, and more slippery. Definitely some things to look into.

For the DSC light to be off, just turn the wheel all the way left then all the way right and tada :) (once should be enough, the skiddy marks will stay, but those will be gone after restarting the car) I need to do the Sohn/CoF adapter change on mine. In this situation (after battery removal), I'd recommend on the first start to let the car warm up without touching the throttle and let it run for a bit more, until it re-learns how to fuel the car.

[@kylerpowney9771]

once again i gotta point out that the SOHN adapter is not a replacement for premix its still not injecting enough oil into the rotor housing and its a series 1. the sohn adapter only increases bearing life not apex seal life. for a s1 you should premix 6-8oz per 10gal premium gas even with a sohn adapter and premix more if your doing a track day. good luck on your project i daily drive an rx8 and its a riot.

Being a former rotary afecionado as a teenager and blowing seven 13B Turbo 2 motors after they were built and tuned right. I can honestly say from the experience the rotary engines weak link are the Apex seals. Any type of detention will damage them if you didn't blow the motor the first or second time you had deteination due to running lean eventually the motor will blow. On the positive note the rotary engine is the only engine you can drive home on a blown motor no tow required😂

Hello Fitment Industries! Continue your excellent work. Have an important question: could you try putting gasoline high 91 or 93 octane in the SOHN ADAPTER “RESERVOIR” just like you do when you premix. And see if you notice a difference in performance, as rotaries love fuel. Could you please take it for a ride with fuel and oil again in the sohn adapter reservoir and see if you notice an improvement in performance. And leave it in the comments reply box? Thanks for your help! You might even be able to make a video on it.

Keep in mind, the Sohn adapter only affects oil quality not quantity. If the Oil Metering Pump fails to inject enough oil the engine can still see increased wear. There is really no good way of knowing if an old OMP is working properly or not, it is just one of those things you should look at if an engine comes out of a car. Otherwise keep an eye on the new Sohn oil level which can atleast tell you that the OMP is working in the first place. To further increase the oil injection quantity, a flash tuning software like MazdaEdit or Versatune can be used. Also the plastic pieces in the engine bay are made in a way to direct airflow through the engine bay to help cool the exhaust. -------------------- The rx8 is a hard car to really mod, since mazda already squeezed every bit possible out of the car. Most mods will do more harm than good...seen plenty of +30hp hot air intakes on rx8s -A cat delete is usually the biggest reliability improvement (no heat buildup around the exhaust ports) -Swapping to an LS d585 coil kit helps avoid failing ignition issues in the future -New oil coolers with chicken wire protection added to the front bumper will help against overheating your rotors, seals, and bearings -A set of gauges for water temp+oil temp+oil pressure are useful since the rx8 has dummy on/off gauges -Some people swap to series 2 rx8 transmission and differential, which have more aggressive gearing and more robust parts. -Heat shielding on the Lower Intake manifold can help since the Exhaust manifold is right below it -For intakes only the AEM or Racing beat intake systems show around +3 HP increase -Most aftermarket headers provide no gains.....the rx8 engine has no overlap = no scavenging = no use for tubed headers -The rx8 hood is already aluminum and weighs just as much if not less than most carbon fiber versions. -Already has a kevlar-carbon fiber driveshaft
