They keep the fuel explosion safely contained and so maximize power and efficiency. So, if the seal is poor-quality, it warps and causes engine damage. Oil squirts into the intake manifold and the combustion chamber to keep everything lubricated, including the apex seals. Unfortunately, not every Mazda RX-8 owner was prepared to deal with these issues. As a result, Mazda extended warranty coverage for models, Autoblog reports, and upgraded the Renesis engine for But even on the last RX-8s, improper maintenance can still cause problems.
The best option is a rotary-specific mineral oil, with many experts recommending a heavier-weight oil , Derwin Performance reports. There is one more issue, though. Which brings us to the matter of the Mazda RX-8 modification: the Sohn adapter. Some rotary experts, such as Essex Rotary Specialists , also recommend using it. The Sohn adapter, though, separates the lubricating oil from the injected oil by giving the injectors another oil source. This has several advantages, DrivenByMadness explains.
Firstly, it means the oil injectors are constantly getting fresh oil, cutting down on buildup. Secondly, because the engine oil no longer has to pull double-duty, you can switch to a fully-synthetic oil in the main pan without issue. Plus, that oil can be a higher-weight one without worrying about it potentially clogging up the injection lines. Instead, the Sohn adapter sends it out from an under-hood reservoir.
We cannot confirm if the Sohn adapter, combined with using a 2-stroke premix, is solely responsible for improving Mazda RX-8 reliability. Think of the RX-8 as a sports car for everyday use. Mazda realized that customers want a sharper, more performance-centric RX Even Mazdaspeed makes tuning parts for it.
But the best thing? Like any other affordable Japanese sports car , it quickly appealed to the fascinating world that pursues every drop of performance: the aftermarket. Of course, intakes and exhausts are entry-level. Next, ECU tuning and remapping; eventually moving to turbochargers, superchargers , nitrous, and motor porting. Horror stories of catastrophic motor failure and excessive oil consumption scared away interested buyers. Initially, this was true to a degree.
Early ECU flashes failed to supply enough oil for seal lubrication. After a few years, most problems were ironed out. Now though, the big problem is inefficiency. Because of their design, rotary motors struggle with fuel economy and emissions. If nothing else, they are simply not powerful enough. If you think about it, it makes sense. The RX-8 has one big advantage: it has a very favorable and popular powertrain configuration for performance purposes.
FMR: front mid-motor, rear-wheel drive. This means that the possibilities are extensive. More importantly, it serves as a great base from which to work. This is a bit of a double-edged sword. It may take a lot of late nights, fabrication, and brainstorming and will be expensive, even if you do it yourself. This means that fabrication is almost always needed. Additionally, depending on the location, insurance will be difficult to acquire, and vehicle registration may prove challenging. Before we get into my own suggestions, arguably, the LS series is the most commonplace swap people have undertaken.
However, the LS motors are difficult to acquire, except in America, so other motors, mostly Japanese, are an acceptable alternative. The legendary JZ motors and RB motors are both plausible and options popular for their limitless potential. Four cylinders are also swapped into the RX People have even swapped other rotaries into the RX-8, either from the RX-7, or a custom-made 3-rotor.
Then there are some oddball swaps, which will generally require a lot more knowledge and skill to pull off. By no means is this a comprehensive tutorial on how to put a different motor into your RX The list will go from sensible, to plausible, but incredibly arduous. Not to mention one of the easiest, and well-recorded. We do have a complete RX8 LS swap guide here with all the info you need for the installation, make sure you read it before you build. The LS family is broad , but the 5.
The LS motors enjoy the distinct benefit of being extremely prevalent, so parts are readily available. Of course, if you feel that it lacks zest, the LS motors enjoy a massive performance aftermarket. Of course, there are lots of different transmissions available for it, depending on how much power you want and what option you prefer.
T56 is typical for manual drivers. But really, the sky is the limit for motors as well understood as the LS. However, kits are also available for it. They may not be completely plug and play but do cut down on required fabrication work.
It also sits well back, but the motor does hang over the front wheels. You can expect the car to weigh around 1, kg after the swap, and the weight distribution to shift forward slightly. You may notice reduced agility, but plenty of gains in low-end grunt and speed. The heavier nose may also encourage a livelier tail. Referring to them will save you a lot of time and effort. By reading, researching, and forum prowling, a Corvette-powered RX-8 should be a simple proposition.
They have a video showing their own LS-swapped RX-8, see below:. If you want to deviate from the norm, the V8 motor Toyota offers a feasible RX8 motor swap to make. The UZ motors, like the LS, span a long period but have a much smaller family. These are aluminum, with forged rods and high compression. Nevertheless, the 4. Either way, Toyota was acclaimed for overbuilding motors back then, and the 1UZ-FE is especially rugged.
The original big Lexus LSs with these motors generally returned 20 mpg combined, so you can expect better figures for the light RX With a mild supercharger with a modest boost of 6 psi, horsepower is possible. Turbo and naturally-aspirated tuning are also common for the 1UZ. The RX-8 steering rack may also be too big for the UZ motors.
Otherwise, for manuals, the Toyota W58 seems to be the go-to option. If you understand Russian, their forums may have something for you. This thread also contains some information regarding the RX8 motor swap. The 4. Still worth a look. Then there are creative options that are quite impractical. The supercharged, fire-breathing M 5.
Photos of a Nissan 4. Possibly one of the most exalted motors of all time, the JZ family needs a minimal introduction. Keep in mind that with one of these, your RX-8 will most likely turn into a drag car or cruiser rather, than a time trial virtuoso. The big question is whether to go for the 2. The 1JZ is a more realistic choice, being both lighter and more affordable. Both motors have similar potential, but in terms of brute force, the 2JZ is difficult to argue with. But of course, these numbers mean little considering that the JZ motors are almost always modified to some extent.
There are stories of the non-VVTI motors running routinely at over hp, without breaking a sweat. The 5-speed will be a better choice, with the same bolt pattern but stronger overall and with a better gear ratio for forced induction. With an adapted bell housing, you can avert a whole lot of fabrication and extra expense.
More information can be found in this thread here. If you can afford it, the fabled 6-speed Getrag V is one of the strongest there is. They have a video showing the swap too. This thread has a completed build with useful information, and if you are really interested, check out this Facebook page hosted by LS1RX8, made for like-minded individuals.
This little article shows the potential one gorgeous drift RX-8 has. Also, did you notice the body kits above? Perhaps most intriguing, is the LFX swap, a 3.

This is a small and light but powerful motor known for its reliability and its unique, chamberless design. The award-winning motor was created based on the experiments of German engineer Felix Wankel. Their small size and power-to-weight ratio make the motors good for kit cars or even light aircraft. Specifications for this motor include:. Mazda RX-8 motors are simple and reliable.
Since there are not as many moving parts in these Wankel rotary motors, the motor should run for a long time. You can expect your replacement motor to last at least , miles. It is not uncommon for Mazda RX-8 owners to report theirs lasting well into the ,mile range.
Routine maintenance and how you drive play important parts in how long the motor will last. A well-maintained RX-8 motor should serve you for many years. The Mazda RX-8 1. Six-speed automatic models go down a bit to horsepower. It creates pounds-feet of torque at 5, rotations per minute with either transmission system.
Standard coupes should go from zero to 60 miles per hour in just around 15 seconds. Jdm Mazda RX-8 13B renesis 1. Mazda Rx8 ps 2. Mazda RX-8 1. Mechanical and suspension improvements included a new performance exhaust system, upgraded spark plugs, grounding kit, lightweight flywheel, re-balanced eccentric shaft, performance brake pads, stiffer anti roll bars, four point front strut tower brace, rear strut tower brace, as well as a set of height and damping force adjustable coil-overs.
Mazdaspeed also redesigned the aerodynamics of the car, giving it a new front bumper, with enlarged venting and oil cooler ducting, as well as side skirts, rear under spoiler, and a rear wing. These accessories included both parts that weren't equipped on factory Mazdaspeed RX-8's as well as nearly all the parts equipped on the factory Mazdaspeed Version. This allowed standard RX-8's to be upgraded to Mazdaspeed standards through dealerships around the world.
The kit includes a roll bar, sports radiator, oil-cooler kit, tow hooks, and racing brake pads. The Shinka takes its name from the Japanese word meaning "transformation" or "evolution". Sand color parchment leather and suede interior along with subtly chromed inch wheels. Out of the total production of 2, vehicles, 1, were produced for the North American market. The most significant mechanical change were slightly revised Bilstein shocks and suspension cross member injected with urethane foam to improve ride quality.
Launched in , the 'Evolve' was the first special edition for the UK. The new model was named after the original Mazda concept car seen in Detroit in and was limited to a production run of just cars. Based on the hp PS; kW high-power version, it had several unique exterior features. Inside, the Evolve features unique stone leather and alcantara sporty seat trim, plus black leather-wrapped steering wheel, gear knob and hand-brake lever.
This car was jointly developed with motorsports company Prodrive. Only available with a six-speed manual, it featured custom spoke alloy wheels supplied by Italian F1 team supplier OZ Racing in "Dark Silver" finish, mirrors developed to reduce drag, front and rear black mesh grilles, and a rear spoiler to provide more stability at higher speeds. Both the wheels and rear wing are badged in carbon fiber with "Prodrive". Significant revisions were also made to the suspension to improve the handling: dampers from Bilstein and coil springs from Eibach are used in addition to reducing the ride height by 15 mm 0.
Finally, the car was supplied with a unique upgraded twin exhaust system, with exhaust tailpipes branded as "Prodrive". It was available in two colors, Galaxy Grey and Brilliant Black The Revelation was an Australian special edition of the RX-8 with a limited production run of cars. The model incorporated the top specification features of the standard RX-8 with the 9 speaker Bose sound system, leather seats in a sand beige color, more piano black accents on the interior, and came with the same 13B Renesis rotary engine.
The revelation though, added stiffer anti-roll bars, foam-filled cross members and special edition grey spoke alloys. It also came with xenon headlights with chrome bezels, while being the first Mazda sold in Australia with keyless entry and start. The 'Nemesis' model is the third special edition model launched as a UK exclusive. It was launched in , although some cars were registered in due to stock runoff.
Based on the standard hp PS; kW version of the Mazda RX-8, it included a unique stone leather seat trim interior and came with a five-speed manual transmission. The Nemesis has several other unique exterior and interior features. Two exclusive colors were available, Copper Red Mica and Stormy Blue Mica, each Nemesis also comes with a polished aluminum Rotary crest on the front air dam, polished aluminum side air-outlet trims behind the front wheel arches, special B-pillar trims with a Rotary crest and 'Nemesis' badging.
Inside, these special edition models also featured Nemesis branded luxury carpet mats and Mazda RX-8 branded aluminum door scuff plates. Like other standard hp kW; PS RX-8s, the Nemesis has front fog lights, heated front seats, electrically operated driver's seat, climate control air-conditioning, nine-speaker BOSE premium audio system with 6-CD auto-changer, plus a black leather-wrapped steering wheel, gear knob and hand-brake lever.
Each Nemesis buyer also qualified for a complimentary Prodrive experience day. Just examples were built, in Copper Red and in Stormy Blue. The Mazdaspeed M'z Tune was focused on performance without the expense of comfort, and was equipped with a performance exhaust system, lightweight flywheel, improved radiator, Bilstein shock absorbers, and sport springs. The car came with a new exclusive aerodynamic kit, featuring a new front lip, side skirts, and rear lower bumper.
Production run was limited to cars. All cars were finished in Sparkling Black paint, with inch Monoblock wheels. It had spoke, inch diameter alloy wheels of a new design that were later incorporated in the facelift. Also added were blue-light front fog lamps, a 40th Anniversary badge on each front wing and an aerodynamic rear spoiler. Exclusive sport-tuned suspension with Bilstein dampers were added along with an enhanced urethane foam injected front cross member intended to improve steering feel.
The 40th anniversary limited editions were slightly different in the various international markets. The Japanese version came in Marble White as a homage to the Mazda Cosmo Sport, which was initially only available in white. In North America, this special edition was available only in For Canada - production was limited to cars. The interior had black leather with copper red accented door inserts.
For the Australian market, only examples of the 40th Anniversary Edition were produced in exclusively. The interior came with exclusive white Alcantara and black leather seats with contrasting white stitching. In the United Kingdom, this edition was limited to cars which came in two exclusive exterior colors — Metropolitan Grey Mica or Crystal White Pearlescent. Seats were trimmed in black leather with stone Alcantara midsections.
In November , Mazda improved the RX-8 body rigidity through the addition of structural reinforcements, by adding a trapezoidal shock tower brace and enhancing the local rigidity of the front suspension tower areas. The rear suspension geometry was revised for better handling, and the final-drive-gear ratio on manual transmission cars was shortened from 4.
While minimal, these changes gave the updated RX-8 increased acceleration and performance. Mazda engineers claimed that the 2nd generation RX-8 was slightly faster than the previous generation due to the lower gearing and improved suspension. New catalytic converter was used to reduce clogging that resulted in overheating exhaust stream forward of the catalytic converter and eventual rotor side seal failure, which was responsible for majority of RX-8 engine failures.
Due to higher usage cycle that is two to three times higher in Wankel compared to Otto cycle, ignition coil packs on RX-8 can degrade much sooner than Piston engines using similar hardware, and cause unburnt fuel to reach the catalytic converter, clogging it and cause engine overheating leading to side seal springs failure. The updated RX-8 also received design enhancements that were meant to freshen the styling and give the RX-8 a new look, without impairing the basic design theme.
Refinements for the model year included a more aggressive restyled front and rear bumper as well as a new front fascia. The updated RX-8 also came with sporty, high-quality finish front and rear headlamps as well as larger exhaust pipes now measuring 90 mm 3. The RX-8 also offered a new five-spoke wheel design featuring a symbolic and sporty design reminiscent of the rotary engine, with different arrangements for each wheel size. A rear spoiler was also added dependent on the trim level selected.
There were three trims available to consumers from to Sport, Grand Touring, and R3. In , Mazda unveiled a Mazdaspeed RX-8 equipped with racing seats, and a new aerodynamic package for the refreshed RX Mazda however didn't end up selling any new generation Mazdaspeed editions or accessories to the public. The R3 version was first introduced in in Japan.
This version was very limited and had the 1. The R3 model was again introduced in The R3 package added slightly improved suspension over the base model by adding Bilstein shock absorbers and a foam filled front crossmember to improve rigidity.
It also came with inch forged aluminum-alloy wheels and high performance tires. On the exterior, the R3 had a different, lower front bumper sporting a splitter, lower side sills, and a standard rear spoiler. There is a pair of special Recaro seats up front, along with the same watt Bose audio system, along with Bluetooth and the Mazda advanced keyless entry and start system.
No electric sunroof was offered in the R3 model. It is the fastest and most expensive RX-8 ever made. The Spirit R was limited to only 1, cars and exclusively sold in Japan. The car had two transmission choices: a 6-speed manual transmission and a 6-speed automatic with paddle shifters.
Features exclusive to the RX-8 Spirit R were bi-xenon headlamps, 4 piston front and rear red brake calipers, high performance Bridgestone Potenza summer tires, a 7. Mazda reworked a lot of the engine and related electronics in order to enable the engine to have the highest amount of peak power. A high-pressure fuel pump was added, as was a larger radiator with faster fans to help with cooling. The cold air intake system was upgraded, and the S-DIAS gained a second intake port, which would open at 5, rpm to allow more air into the engine.
The oil-metering pump was upgraded to provide more oil to the rotors. A less restricted stainless steel exhaust was added with larger 3. A Tochigi Fuji torque vectoring limited-slip differential was added. A bespoke track-ready suspension with Bilstein dampers and a urethane-foam-injected front suspension cross member was added. Mazda also focused on reducing weight.
The front hood, rear doors and trunk lid were made from aluminum. A magnesium steering frame, together with a lightweight carbon fiber prop shaft, was also added. The automatic transmission model included way adjustable power leather seats with lumbar support and 2-position memory in black with red stitching, and inch lightweight BBS dark gunmetal alloy wheels wrapped in Bridgestone Potenza summer tires.
Some models came with red leather seats with white stitching. A tire upgrade was also available, swapping the Bridgestone's for higher performance Falken extreme summer tires. The automatic models could be specified with the manual transmission model's Recaro bucket seats and inch wheels. Sales of the RX-8 ended in in Europe after failing to meet the region's emission standards.
The production of the RX-8 ended in in Japan. Mazda has produced , units since The warranty extension covers only the engine core which consists of the rotor housing and internal parts as well as the seals and gaskets. It does not include clutch or drive train transmission or differential. An extended engine warranty for emissions was not offered in any other RX-8 markets. The RX-8 has been campaigned and used in various racing series by privateers. It has seen a considerable amount of success, the most prominent of which being the and 24 Hours of Daytona GT-class wins campaigned by SpeedSource Race Engineering.
This victory also marks the 23rd endurance race win at Daytona by a Mazda rotary-powered race car. While the cars are powered by the 20B rotary engines, the car is in fact built on a tube frame chassis and not on the production car. The category was renamed in to the Mazda Racing Series and now some of the largest grids in the country.
Developed in two years, the class was designed to provide the cheapest way of going racing in a performance car. The class stipulates that the RX-8 entering the race must have a valid MOT and retain creature comforts such as air con, heater and stereo, therefore allowing the car to be used as a daily driver, as well as to and from the race track. It was named on Car and Driver magazine's Ten Best list for , , and It also took home 1st place on Car and Driver's "Four of a Kind" comparison test.
