04-11 Rx8 No Recess Solid Corner Seal Set

This was designed by David Atkins and has been patented.
This is an excellent upgrade to any engine. These are desirable under high boost or nitrous applications.
This is a one piece corner seal. Can be used in place of the 2 piece design with plug. Can be used with the wire type corner seal spring or the 93-95 HP wafer type spring. The 93 Style spring is recommended.
Mazda basically copied our design with the Rx8, getting rid of their faulty rubber corner seal plug and opting for a steel one basically making their corner seals solid like these.
These are the same as our original solid corner seals without the depression in them.

Cryo Treated Rx8 Side Seal Springs

The side seals and springs on rx8 engines goes directly over the exhaust port and therefore experiences extreme heat, the cryogenically treating process helps the springs deal with this situation.

AEM Water/Methanol Injection Kit

What it does: The AEM Water/Methanol Injection System injects a mixture of water/methanol into the intake of a forced induction engine. Injecting water/methanol allows users to run more boost and ignition timing to gain horsepower and torque. Gains as much as 20% more horsepower and 25% more torque on pump gas are common.

The AEM Water/Methanol Injection System comes loaded with more standard features and high quality components that any other comparably priced injection system on the market today. The AEM injection kit comes with a 1 gallon tank with built-in low level switch. The "Boost Safe" injection readiness system comes standard in all AEM Water/Methanol Injection Systems. A check valve that prevents unintended fluid flow is included standard. One injector and three interchangeable nozzles are included to cover a wide range of potential horsepower levels along with 20 feet of injection tubing to facilitate the system being installed on practically any vehicle.

Key Features
· 1 Gallon tank with built in low level switch
· Boost referenced progressive controller
· “Boost Safe” readiness safety system
· Check valve to prevent unintended fluid flow
· One injector and three nozzles to cover a wide range of HP levels
· High Pressure Recirculation-style pump
· LED dash light for system status and low fluid warning
· 20 ft. of injection tubing

Atkins Designed Six Port Actuator Valve Kit

These fit a 1986-1992 Non Turbo Six Port Engine. Stock actuators have a dead spot at the end of them where the intake air hits cavitates instead of continuing into the engine smoothly.

Our intake actuators fix this problem by creating a smooth transition from intake to engine and generating more power.

Don't waste time installing inserts into your actuators, just put new, and better actuators in and be done with it.

Atkins Rotary Dynamic Balancer
  Although we have always static balanced our rotary engines in the past, we were forced to send our rotating assemblies out to be dynamically balanced. That is no longer the case, this is our new rotary engine dynamic balancer setup and ready to go.
