PILOT BEARING REMOVER TOOL
Pilot Bearing Remover Tool
To remove the old pilot bearing the bearing MUST be gripped at its front end. Very few of the aftermarket pullers we tested were able to do this correctly. They often tended to destroy the bearing making removal even harder.
To use the tool simply insert the attachment into the bearing, being sure to get it to the end of the bearing, insert the tapered / threaded end of the slap hammer part and screw them together until the bearing is firmly gripped. Then just “slap hammer” it out. Should take less than a minute.
This tool prevents eccentric shaft damage when removing bearing.
This tool does fit other cars including Miata. We do not have a list of cars that it will work on. The RX pilot bearing/input shaft measures .588″. If your application also has a .588 shaft/bearing, this tool will work.SKU: 49-1285 -

PORT TEMPLATE TOOL, J-BRIDGE INTAKE 4-PORT
PORT TEMPLATE TOOL, J-BRIDGE INTAKE 4-PORT
The Racing Beat Intake Port Templates allow you to undertake your own “J-bridge” port efforts on any 12A or 13B rotary engine (except 13B 6-port). These templates are traced from Racing Beat’s own master templates, which are the result of years of research and development. The actual port shapes are traced on thin sheets of aluminum which you must first cut out, testing your ability to use a die grinder effectively before attempting to port an expensive engine component. The finished template is held in place and the porting shape is then traced onto each housing. You must then use your own judgment to develop the port shape beyond the scribed line.

PORT TEMPLATE TOOL, RACE 13B EXHAUST
Exhaust 13B Race Port Template, 74-95 All Turbo and Non-Turbo
Actual template shown in photo.
The Racing Beat “Race” Exhaust Port Templates for all 13B peripheral port exhaust rotary engines allow you to undertake your own exhaust porting efforts. The race version of these templates open the exhaust port further “upwards”, increasing the port timing duration which results in more intake-exhaust overlap and better high RPM performance.
The Racing Beat laser-cut aluminum porting templates are patterned after their own original master templates. Designed and refined over decades by Racing Beat’s legendary engine builder and co-founder Jim Mederer, this exhaust port template gives you a powerful resource to assist you in your engine upgrade project.
Incredibly easy to use, simply mark the template position as instructed, spray the exhaust port area with marking dye, hold the template in position (we use a simple hand clamp or a office paper clamp), and then scribe the new port shape onto the housing. It’s really that easy.
Porting Effort
During your porting effort we suggest you stay within the boundary of our template shape. This shape has been designed to yield excellent results for a broad range of engine building applications. However, you can certainly get more aggressive with porting efforts beyond the template line, you must then use your own judgment and expertise as a guide.SKU: 22216 -

PORT TEMPLATE TOOL, STREET INTAKE 4-PORT
Port Template Tool, Intake Street Port (4-port)
Racing Beat Intake Port Templates allows you to undertake your own “street” intake porting effort on most 12A or 13B rotary engines (except 13B 6-port and Renesis). Rotary tuners long ago discovered that changes to the intake port shape will alter intake timing, allowing increased airflow and velocity improvements. These templates are traced from Racing Beat’s own master templates, which are the result of years of research and development. The actual port shapes are traced onto thin sheets of aluminum which you must first cut out, testing your ability to use a die grinder effectively before attempting to port an expensive engine component. The finished Racing Beat porting template is held in place and the porting shape is then traced onto each housing. You must then use your own judgment to develop the port shape within and beyond the scribed line.
