The rx8 isn’t a drag car or a 0-60 car . It was built to be a good affordable FUN track car

[AlecFloyd-sede]

The biggest limit to power is the exhaust ports, earlier rotaries with the peripheral exhaust ports could do ~300 hp n/a with a good peripheral intake port added. Unfortunately with the renesis exhaust ports being in the side housings and the water jacket running really close to the ports you aren't able to do much to them in terms of porting. The intake ports already flow an enormous amount in stock configuration, way more than the exhaust ports can expel. The rotors are also pretty weak when it comes to additional horsepower, so that is a reliability concern. Also, contrary to popular belief, apex seals are not a problem with the renesis, like they were in earlier rotaries, as they don't pass over the exhaust ports. The S2 engines even have a 3rd oil injector on the rotor housing providing additional lubrication and cooling to the apex seals. As long as the omp is properly functioning and/or you are running a quality premix at the proper ratio, you should never have apex seal issues in the rx8. The side seals and oil control rings are the main point of failure in these engines.

You buy an RX8 just like a Miata for its amazing handling not big horsepower.

Mine is Bridgeported, i have all supporting mods, turbo charger soon.

[pedrosued]

Rotary its the piston killer when you know what you are doing. Piston will be more expensive for race with it. My father was on a 13bpp Racing Beat engine for more than 2 years racing lol...All the piston guys pull out the engine to refresh at every race. 😅

Increase performance on Rx8?

Step 1: Yeet that engine
Step 2: Get a 13b REW
Step 3: 5 speed transmission out of the Rx8 or FD
Step 4: Install
Step 5: Count the money you saved from not getting the bolt ons first
Step 6: Brap brap

the only way youll get to 230 at the wheels and beyond is a turbo or engine swap

I went the cheap route and went engine swap for a 1.8t audi engine and its the best thing I've ever done its so good to drive especially with a nice large turbo on it like mine

[kailirx]

I have a ported engine and currently dynoed at around 220WHP, CAI, Street Port, Racing Beat Headers with full 3 inch exhaust. Pettit Supercharger going in next. Already have all the cooling mods, HOWEVER I can tell you the car is slow af compare to modern day hatchbacks with turbos

[benfps]

With good compression and you drop the clutch at 5k yeah about 5.9-6.1 seconds don't know what ur yappin about

[dubbleA]

I'm an Rx7 guy so I have to use a standalone.
Do they have tunes for Rx8 that will allow you to run half bridge on stock computer?

[tonytersa]

What happen if...RX8 R3 S2 232hp??? Do you think it could be a little more fun on the straights line and a little more reliable with the basic settings?

[johnpaul]

I think you mentioned in one of your videos that there was a Japanese company that use to import aftermarket lower intake but no longer ships to usa? Do you happen to remember their name?

[jamiebeattie]

Mine is 260 bhp on 99oct and premixing my fule and no turbo yet pulls all the way to 9k

[ObtuseRubberGoose]

I wonder if a higher final drive is also worthwhile? No idea what the ratios factory are like but it is a 6 speed that revs to 9k so having shorter gears couldn't hurt could it? lol

[supermoop]

Just get good wheels, tires, and suspension and have fun on the track. 😊

[JayCras]

my 2004 with 145, 000 miles still does 0 - 60 mph in 5 seconds and change. Tried this with a couple times with different friends timing me from a stop light using a stopwatch app. I think your shifting way too soon or have an RX-8 with the engine used with automatic or 5 speed transmission. You need the 6 speed and it has to be pre *Emissions reductions crap.

[angel_carlos]

You wont get 300whp from a NA rx8. 200whp with full bolt ons and tune. Mazda really squeezed everything out of this motor

[jerryglennie]

Why does no one point out N/A with an injection kit as a bolt on mod?

[ThunderCatD]

All the torque is from 6 to 9 rpm bolt one do absolutely nothing intakes do nothing unless it's a racing beat revi or Mazdaspeed intake the rest drop horsepower headers do nothing catless midpipe lets it flow better and won't clog if you premix this is ALL wrong.

Кто знает в чём проблема?- Глохнет на светофоре( двигатель прогрет хорошо). После этого заводится всё хуже и хуже. И вообще потом не заводится, пока не остынет. Пробег 87000км.

Does anyone know what the problem is? - It stalls at traffic lights (the engine is well warmed up). After that, it starts worse and worse. And then it doesn't start at all until it cools down. mileage 87000 km.
