I owned a black RX-8 for 4 years and loved it. The car never let me down once. Drove it up to about 90k miles and then sold it. It was in amazing condition and still had excellent compression because I took care of the motor (frequent oil changes and pre-mixing). I wish I had never sold it. I've been trying to find a good condition RX-8 for the last 4 years with no luck. Every car I've found needs new apex seals (at the very least). Literally every one. I've probably driven 8 or 9 cars, and looked at far more than that. At this point it's better idea to buy a car with a blown motor and rebuild it if you're looking to get an RX-8.

[@onyren85]

I owned a JDM Type-S that died on me few years ago, had some fun with it but was dissapointing in many ways. Fast forward a few years later, I bought '99 FD3S and also circumstances happened I got the itch and got another RX-8 Type-S with 49,000 miles.. I just cannot justify this car, rose tinted glasses effect - Fun to drive but ultimately pointless. There are better daily cars and the FD3S is a better sports car. I 1000% regret getting it and now I can't even get rid of it even for a low price... Real sad... :(

Joy to drive and the sound.. Gota love a rotary. Eventually a good tune will be done. Rotary's are lil different then my k serie's cars im use to tho lol nice vid👍

[@eroc7667]

Great content. HEADER IS LIFE! I have an 07 gt with just about all there is. Act prolite flywheel and counter balance, ls2 coil swap, full exhaust with agency power dual res mid pipe and cat back, lightweight pulleys and the full package of mishimoto cooling items. Baseline figures were right at 180.8 whp. Chris at rotary performance in garland tx dyno tuned her using mazdaedit on a cool but rainy day. Mustang dyno but I'm unaware of any rate if correction. After several hours and nearly a dozen fourth gear pulls she put down 188.6 whp and 132.5 ftlbs. I went in with that sweet goal of a nice round 200 fully expecting to at least come closer. Engine is in great health with low miles. When speaking with chris about the results as soon as he started talking i knew where he was heading. Volumetric efficiency being our weak point. This being explained to me as a measure of air in vs out. My car was running at 90-95 percent while you would want this at 100-107 percent. The one part i didn't spend what i should of was the header. It was the first mod i acquired and was a "hook up" from a friend. It was clearly not the best put together thing but was much lighter than stock and looked better. Point being... With all the mods and care i have taken as an owner, i still couldn't come quite close enough to my power goal. Racing beat.. Here i come :)

[@TheSlipAngle]

188 whp on a mustang dyno is probably about the same as what my car made. Mustang dynos always read lower than DynoJets. What header do you have at the moment?

[@eroc7667]

@@TheSlipAngle A manzo i believe. Had to bang one of the tubes for clearance and grind one of my mounts to keep it from vibrating endlessly. While speaking with Chris at rotary performance he swore by the racing beat header, stating that it, paired with almost any set up is the overall best option. Almost 600 for a new one though 😬

[@darrenlucas2768]

@@eroc7667 I had the same problems fitting mine....just couldn't bare to cough up that huge amount for the racing beat header and figure mines still a big improvement over the standard iron lump. Your power figures look good to me , over here in the UK the general opinion is the six porters make 170 to 180 max at the wheels stock. I had mine street ported with the racing beat template and I have to say mated to a full system ( not expensive one) and a 200 cell cat it really pulls well post 5 k....I think for what it is it's a marvel and ok,maybe an s2000 might have it pipped but in tuned form you can hold one in a rolling run as I've found out.......and that is no mean feet for a 1.3 little drum of an engine

[@jo-qp7mz]

I also bought the cheap one but Port matched it to the exhaust holes because they were sloppy eventually I want to cut the collector off of it because everything but the collector looks the same as the racing beat but yeah I can't cough up that much for a header either

Awesome video all around! Thank you. I really enjoy the rotary/8 content. I bought a 06 Shinka last year, had a baseline done (can't remember the CF) but only posted 140whp. MIL was on, and I've been replacing vacuum lines, sensors, going to be going back this summer.

[@NateRist]

Drivetrain power loss is about 20%. With 238HP at the flywheel that puts you at 190WHP and you made about 10WHP more, so your flywheel HP should be right around 250HP

[@Bluebeast2005]

Hello Nate, I too like you would quote a % for tranny loss; however be careful that's not very accurate. Take high hp cars 400-600+hp they don't loose 80-120hp through the drive train.

[@MrAntimationStudios]

The 231 stock power figure is not correct (yes I'm saying Mazda lied), a good stock 6 port usually makes about 215-220 at the crank.

[@lukeberry94]

It depends on what testing methods you use, and when you do it. If you remove the ancillary items and use an engine that has just bedded in, you can get around 181KW with the ECU firmware that Mazda never actually released. In a closed, controlled room, a fairly fresh engine gets about what mazda said, but it doesn't take long for the horses to leave the stable.

[@peterparker21]

Antimation Studios I think this is true for a number of car manufacturers. For instance the highly publicized volkswagon, and then Hyundai. They just make numbers look good for a particular market. Let’s say gas mileage for sedans, bhp for sports cars etc.

[@peterparker21]

I’m going to do the same mods I think and see what happens on my R3. Minus the pulleys.

[@lazygamemaster748]

It's one of those things people don't realize about these cars. They are actually remarkably well tuned stock. There is very little to drag out of it with out FI. Almost no gains through Bolt on mods, minimal through tuning. Largest ways to gain power are just cat delete headers and a tiny bit of tuning. I've owned 3 of these, all of them were terrible, and I loved them dearly.

[@I_know_what_im_talking_about]

I think the Renesis is pretty much maxed out at this point unless you boost it but then reliability will flush down the toilet. I vote you enjoy it as is. That’s how Mazda designed it to be. Don’t ruin it. Nice numbers overall for a 1.3L haha. I wish mine was as healthy as that. I’m probably in the 175s due to the low compression. ☹️

Yup, I agree. It's pretty good as it is now honestly. I think overall I am pretty happy with how this car is for a daily.

[@TexasVexes]

Wish I could daily mine bro. Those are some great numbers. I’ve found a person local who can do a 13b-rew swap and use rx8 face plate for rx8 accessories. If I turbo it’s gonna be rx7 motor b/c lower compression engine and it likes tuning more. But If I don’t turbo I’ll do what you did and just port the Renesis exhaust ports and bolt ons/ecu.

[@cliffynjovelyn893]

Anyone tried an Odula throttle body? They port it out and replace the butterfly for more gains, I am super keen for this!

[@spacefleming5390]

Will you be doing more tuning with mazdaedit soon?

[@Powerhauz]

That's damn good for also being emissions compliant. Have you thought about the BHR long tube header for "some torque"? Thinking of going Haltech or Adaptronic standalone? Thoughts on E85 for the rotary? Stoked for the s2k build. Glad your 8 is at an exceptional level of health. My own 8 won't be ready until I get back and I put it all together. Current plan is BHR long tube header, BHR resonator, HKS hi-power single exit exhaust, AEM intake and Adaptronic PnP modular ecu with E85 flex sensor for future potential use.

[@TheSlipAngle]

I looked at the BHR, but it's quite expensive for a mild steal header. I also wanted to be able to run the big RB resonators to keep the noise levels down. Eventually I am going to retire this car as a daily and put a 20b or something in it in which case I'd run a Haltech. Not a fan of E85, I like the convenience of 93 pump. On an NA application the e85 will allow you to run more ignition advance to make a few more hp, but I don't think that is good for longevity of the motor. I'd be interested to see your build as it unfolds though. Keep us updated brother!

[@Powerhauz]

I'll keep the updates coming and thanks for replying. I'm deploying in a week so project start is pushed until I get back. I'll have suspension, intake, engine, and steering wheel mods (thank you for the video btw) waiting for me. I'm a little skeptical of E85 as well, but the tuner I'm going to use is doing extensive r&d on it for the RX-8 specifically right now. I guess I'll have time to wait and see. Also while I'm away I get to math out how to shove 11" wide wheels into those awesome arches without flattening the pinch weld on the inside. Gotta squeeze 315's to keep up with the national prepped BMW's in DSP. Have a good week. 🤙

[@quattro4468]

Always use tuners who have ample experience on rotaries specially renesis engines for rx8. The rx8 engine is very different to the rx7 and distribute heat differently.

[@TheSlipAngle]

Maybe a tuner who is familiar with Rotaries and understands their leading / trailing spark, but as far as the actual tuning, the process for tuning the Renesis is no different than an older 13b.

[@quattro4468]

@@TheSlipAngle but it is different. Exhaust ports on both engines is so different that heat accumulates on one side of the engine. This is a physical limit to how much you can push performance. This was done with the focus of mpg to appeal to more mainstream consumers. The 13b rew hasnt this problem.

[@TheSlipAngle]

Yes, the RX-8 got rid of peripheral exhaust ports in favor of side exit. This creates more heat for the side seals. I've talked about this in previous videos and said that I don't think the Renesis is a good choice for a track day motor where there will be long periods of sustained high RPM. This is more a limitation of the engine design and not the ECU tuning.
