AUTOEXE Motion Control Beam Front and Rear for Mazda RX8 (Series 2, 2009-2012)
Night and day difference, even on a bone stock suspension. While installing the AutoExe front strut bar greatly enhanced steering response and turn in, the handling improvements from it was very subtle. Likewise with the AutoExe tie bars installed in the front and back of the car. More solid feel, less suspension parts deflection under cornering loads. These Motion Control Beams took away the vibrations that are slightly felt in the steering wheel from small road surface imperfections. It also took away the bumps felt from pavement gaps and mostly the rumble felt from railway crossings and brick roads. Going through small pot holes and road patches, the stock suspension is finally doing its job to dampen away those bumps and doesn't get fully transmitted throughout the entire car. Big bumps, you don't hear a loud hollow "thump" emanating from the back of the car. Just a solid "thud". The car used to understeer and now it hardly does. It handles quite neutral now, even on bone stock open differential, and did I already say bone stock suspension? This is win win, all around, without sacrificing anything.
GENUINE MAZDA OEM Intake Solenoid for Mazda RX8 (Series 1 & 2, 2003-2012)
Happy 8's day people! For you series 2 owners, here's the easiest way I found to change these little suckers. RX8 Upgrades providing the genuine goods as always. Remove the air box/ CAI, remove throttle body and remove the top part of the UIM only, this will get you easy access to the solenoids. Now you could remove them from this point, but removing the oil filler neck along with the vacuum chamber the solenoids mount to makes it FAR easier to change them. This whole job can be done in an afternoon for a mechanically minded person. On reassemble, don't forget to place the vacuum reference back onto the bottom of the manifold (has a green check valve) otherwise no valve will work. Reassemble and enjoy. PN is KL01-18-741 for those chasing the part
HKS Hi-Power Cat-Back Exhaust with Titanium Tip for Mazda RX8 (Series 1 & 2, 2003-2012)
I have the HKS Hi power, absolutely love it. It's much lighter than stock. Got a nice low tone at idle, reasonably quiet at 3.5k rpm around town and doesn't drone much on the highway. It's absolutely ignorant when you get to the redline with a satisfying "Pop POP" between gear changes. Has a unique sort of burble when the RPM's are coming back down.. You will love it too:)
Yes, I believe that's revision C. Racing Beat is a good store for Mazda's, I'd trust them when they say it's the real OEM coilset.
HKS Hi-Power Cat-Back Exhaust with Titanium Tip for Mazda RX8 (Series 1 & 2, 2003-2012)
I had the hks hi power with ap midpipe and it was loud as hell but i loved it until i started getting pulled over all the time for it. You just have to keep the rpms down around the cops.
The Renesis 13B is one of the most rewarding engines ever fitted to a road car, and also one of the most demanding to rebuild correctly. An RX8 rotary engine rebuild is not a job where cutting corners pays off. The right parts, the right condition, and a clear plan before the first bolt comes loose are what separate a successful rebuild from an expensive repeat job. Finally, this range exists to support owners who are serious about getting it right.
For owners considering a Mazda RX8 replacement engine, the critical questions are condition, history and what is included. For example, a known-condition engine with documented preparation gives you a reliable starting point and a predictable installation.
A used Mazda RX8 engine may carry a lower initial cost. However, undocumented history means unknown wear on apex seals, housings and the eccentric shaft. These are the components that determine how long the engine actually lasts. Therefore, weigh the full picture, not just the price.
A rotary rebuild involves sourcing components suited to the 13B’s unique requirements. Unlike a piston engine, the rotary’s sealing system and porting tolerances demand parts that meet correct specifications.
Moreover, genuine and quality aftermarket components are both represented here. Match the rebuild to your intended use: daily driver, weekend car or track-focused project.
Every Renesis 13B engine Australia owner eventually learns the same lesson: the rotary rewards attention to detail and punishes neglect. For example, oil consumption is designed-in, not a fault. In addition, cooling system integrity matters more than on many engines. The apex seals are the heartbeat of the whole assembly. As a result, a proper RX8 rotary engine rebuild addresses all of these points, not just the obvious ones.
Owners looking to buy RX8 engine Australia-wide should treat the engine as one part of a broader project plan. The engine itself is the centre of the job. However, the installation also involves oil lines, coolant hoses, gaskets and ancillary components. Therefore, addressing these at the same time is straightforwardly better than returning to them six months later.
For a Mazda RX8 engine Australia project, sourcing is only part of the challenge. Also, have the right supporting parts ready before the engine goes in. That means gaskets and seals through to fresh fluids and service components.
Getting this right is what makes the difference between a clean installation and a drawn-out one. Meanwhile, browse the related categories for service items and supporting components, and plan the complete engine rebuild project from the start.
A rebuild involves reconditioning your existing Renesis 13B around its known condition and your car's specific needs, which suits owners who want control over the scope of work. A replacement engine offers a more straightforward changeover but requires careful checking of the unit's condition, documented history and what components are included before committing.
Confirm fitment compatibility, what supporting parts are included with the engine, and the documented condition or preparation history of the unit. Understanding what is and isn't included early prevents last-minute parts sourcing during installation and helps you budget the full project accurately.
A used engine typically costs less upfront, but that saving needs to be weighed against the risk of unknown history and undisclosed wear. Engines with clear documentation of condition and prior maintenance carry significantly less risk than unverified units pulled from unknown-mileage vehicles.
An engine project almost always involves more than the engine itself. Seals, apex seals, cooling system components, the oil metering pump, ignition parts and exhaust manifold gaskets are commonly addressed at the same time. Reviewing the full scope of surrounding service items before starting prevents the project stalling mid-way through.
Yes. Series 1 (2003-2008) and Series 2 (2009-2011) RX8 models can have differences in supporting components and ancillaries around the Renesis 13B engine. Confirming your exact build date and series before selecting an engine or rebuild parts ensures correct fitment and avoids compatibility issues during installation.
Genuine new Renesis 13B engines are not a standard stocked item through Mazda Australia and availability of genuine engine assemblies has become increasingly limited over time. Owners should confirm current availability early in their planning rather than assuming supply is straightforward.
That depends entirely on the nature and severity of the engine's issue. Minor oil consumption or a slight power loss may allow limited use while parts are sourced, but symptoms such as flooding, loss of compression or coolant contamination generally mean the engine should not be run until the rebuild is completed. Assess your engine's specific condition before making that call.
