The Racing Beat Street -Port Templates allow you to undertake your own intake and exhaust porting efforts on all model years of the high-power 6-Port Renesis 13B engine. These porting 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.

Included with the Renesis porting templates are detailed instructions and advice to guide you through your porting efforts. Limited clearance on the Renesis side housings creates additional challenges when porting these housings, our instructions provide detailed photos of the most critical areas of concern.

Delivery can be up to 4 weeks if not in stock

Essex Rotary are now please to offer brand new rotor housings for your rebuilding needs. These housings offer a considerable saving over buying them from Mazda (at a price of over £900) each.
Price is per housing  and we are even able to offer the later R3 housing at the same price (if you require R3 housings please contact us to arrange this)

Please note that these housings are factory items and are NOT recon/resurfaced housings.

Due to the high value of these items they are special order only while we strive to fulfill special orders as quickly as possible, please allow up to 30 working days for delivery.

The new oil pressure regulator from Essex Rotary is based on a modified Mazda regulator but is designed to run a higher maximum oil pressure. Bringing the standard pressure on a series 1 RX-8 from  from a maximum of 80 psi and increasing it to around 110psi this increased oil pressure means that your series 1 engine will now run pressures much closer to that of the later series 2 RX-8 (R3)

This makes the Essex Rotary enhanced oil pressure regulator great for ported ad high revving applications, equally suited in a standard engine its a great upgrade for piece of mind.
The main advantage of the increased oil pressure would be to increase bearing protection over that of the standard 80psi found in the series 1.
In our experience we have removed oil pressure regulators from engines that have been running as low as 50-55 psi.

The Racing Beat Eccentric Shaft Thermal Bypass Pellet Replacement can be installed on any 1986 and later eccentric shaft. from RX-8 through to late RX-8’s
The Thermal pellet is designed to delete the traditional oil thermostat found in the front or the eccentric shaft, this unit is known to fail over time and always fails in the closed position reducing oil flow to your engine however you will never know.
Highly recommended to fit at the time of a rebuild.

This Racing Beat oil system upgrade kit contains both the Racing Beat oil pressure regulator and the Racing Beat thermal bypass pellet.



Oil Pressure Regulator

The Racing Beat-manufactured Street High Performance Rear Oil Pressure Regulator for the RX-8 interchanges exactly with the stock rear oil pressure regulator on all 2004-2008 Renesis engines. It is designed to bypass at 90-95 PSI, making it well suited for street-ported Renesis engines and a piece of mind upgrade for normal rebuilds. As supplied by Mazda, the factory pressure regulator is intended to bypass at maximum nominal rate of 80 PSI


Thermal bypass pellet
The thermal bypass pellet is designed to replace the stock thermal pellet found in the front of all eccentric shafts from 1986 onward the stock pellet works like a thermostat restricting oil flow to parts of the engine when cold. however when they fail they generally fail in the closed position leading to permanently reduced oil flow this is not good for your engine. The Racing Beat bypass pellet removes this point of possible failure. The pellet replaces the stock unit and allows full oil flow from cold. So by using the Eccentric Shaft Thermal Bypass Pellet Replacement you will know the oil is reaching the parts it should at all times.































Please Note
The 2009-2011 RX-8 Renesis engine is not equipped with a rear pressure regulator. Nominal oil maximum oil pressure on this application is 110-115 PSI. We do not offer a regulator to increase the oil pressure on this application.
