I’m so pleased that someone is still making videos on RX8, and super pleased that it’s you. You have tons of knowledge and a great way of explaining this superb car. Only you could explain how an ssv works. My 40k miles RX8 has had only minor problems so far, till the 661 CEL. I understand engines but have limited tools and experience in taking them apart. Also I don’t trust our mechanics over here in Uk.

The LS coils are such a worthwhile upgrade. The ignition system is critical on any car, especially a rotary. I put new plugs, wires, D585 coils, and a 700CCA battery in my RX-8 with the 2KW starter and now she fires up on the first stroke every time, hot or cold. I pre-mix with with Klotz, run Castrol 10W-30 mixed with Marvel Mystery in the Sohn and use Castrol classic 20W-50 in the crankcase. I love this car, man. Thanks for the vid!

That’s basically what I did. Bought an 04 manual rx8 with high miles and low compression, but otherwise clean. Had hot start problems and other issues the owner couldnt figure out. Bought it from him pretty cheap and just upgraded the ignition system, cooling, suspension and other little things which fixed the hot start despite the compression. It ran fine for 2-3 years until I was able to save up enough to buy new oem parts to build a new engine. Its probably the best way to get an rx8 if you dont have the 8k+ to buy one with decent compression up front.
@jasonskinner1652

Great vid bro. Also, carbon build up can cause that slow reduction in compression by causing stuck seals. Or if the oil injectors are failed you will get additional internal wear in irons and housings also leading to lower compression. You still can't tell if you'll get heavily worn parts or excessive carbon or just fatigued seals and springs. You make a great point though, low comp shouldn't turn you off from buying a cheap 8. Looking forward to the REW teardown.

Firstly I’d just like to say this is my favorite rotary centered channel. Rob dahm and the Vargas brothers are too freakin advanced for me lol. Secondly. This channel more than any other makes me want to make so many poor financial decisions lmao. I have an ugly RX-8 that I bought for $2500 that actually runs beautifully aside from a power “bump” at around 6800rpm that I think would be caused by the ssv?. Hot and cold starts in like 1.5 seconds or less. I want so badly to get a new intake (currently has a hot air intake system held on with a zip tie) and a new exhaust system (catalyst material is just tink-ing around in there and the mid pipe is welded to the header) then paint. But I’m also operating on a budget lol.

You can alleviate the hot start issues a little bit with a flat cranking pulsewith table set to at least 35ms everywhere above 50c ECT if you have ECU flashing software. The stock ECU calibration reduces the cranking pulsewith at 50c from 35ms all the way down to 3ms by the time you hit operating temp for hot start emissions reasons.

Also, curious in your experience how May miles you’ve seen low compression ones last for before needing to be rebuilt? Does the blue one have 200k original miles?

Great vid as always brotha. My 8s been dumping oil out the exhaust for a little bit now (been driving my truck instead cuz, yeah, gas and oil expensive lol) Haven't really done much other than mess with omp positioning but my gut is telling me its control rings, but then I use my brain and think it may be a bad vacuum leak cause my throttle body was super filthy the last time I cleaned it. The smoking is very random too, but when it does its DURING a pull, not after, so its kinda weird to me. What do you think?

Hey man, you mentioned how your green rx8’s first engine had misfires at high rpm at the track. Mine kinda does that when I bring up past 7k rpm initially but after it gets hot, it doesn’t do it anymore. Also if i bring it up to 8k+ rpm and let off the gas to engine brake it’ll throw a loot of blue smoke out the exhaust. I do have a catless midpipe, but I also have one bad rotor with low comp. any idea what is going on and would it still be driveable for a little while? She starts fine.

I bought a cheap rx8 a couple months ago... the front rotor compression is down to 40 psi and it still runs lol. The rear rotor still has good compression still, and during medium hot starts(she don't hot start) you can hear the bitch is a one rotor for a bit. I bought it knowing it would need a rebuild, but shit I feel like I've had my fun even with shit compression. Tons of people online make it sound like you can't drive them below 7 bar, which is a bit misleading. She just needa cool.

Love the content as always. From your experience, can a 12A last more than 140K on average if owned by a rotary enthusiast under the conditions of daily driving/spirited runs on weekend? My friend claims to have racked up 205K miles on his 12A before a vacuum leak caused hotspot on side seal and blew it, but other rotor had 85psi...meanwhile I got 127K on my RX8 engine and still running like a champ. Is 12A a better longevity rotary engine? What's most you've ever seen? Is there a design advantage over 13B S4, REW, Renesis?
