The BLITZ SUS Power air cleaners are made from top quality T-304 stainless steel. Totally unique, the entire filtration element is made from a fine stainless steel T-304 mesh (200 micron mesh and 150 micron crown). This mesh means the filter will never wear out, and have substantially less restriction than any other filter. Another feature is the super fine pattern of the mesh. This straightens the airflow and dramatically reduces aerodynamic tumble (restrictive turbulence). The BLITZ air cleaners also have fine mesh at the top of the filter, further improving the airflow capabilities. Unlike anything available in the market today, the BLITZ SUS Power air cleaner is by far the best performing and best looking automotive air filter money can buy, which include all the necessary pipe, brackets, and adapters.

Made to order, right here at Essex Rotary using all MSD Components.

The MSD 8.5 mm Super Conductor wire is the performance wire engineered from the inside out, the 8.5mm offers everything you have ever wanted in a wire; incredibly low resistance without electronic interference! In a single 12 In. length of Super Conductor wire there is only 40 to 50 ohms of resistance! That is the lowest resistance of any helically wound wire. To accomplish this, MSD use a copper alloy conductor due to it’s great voltage carrying capabilities. The low resistance results in less loss of spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. So tight, that there is over 40 Ft. of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective electro magnetic interference (EMI) choke.

• Copper alloy conductor has a resistance value of less than 50 ohms per foot for superior spark
• Ferro-magnetic impregnated core creates an effective EMI choke
• Forty feet of conductor is wound into a single foot of wire for high EMI suppression
• Conductor core features Dupont Kevlar material for increased tensile strength
• Durable outer sleeve is a proprietary compound for resistance to high heat or abrasion
• Stainless steel terminals feature dual crimp tabs to grip wire conductor and outer jacket separately

These MSD HT Leads are made to order right here at Essex Rotary HQ, from genuine MSD components. Available in Red or Black cable options (select your preferred color from the drop down menu before hitting the “add to cart” button.

This product is a plug-in ECU designed specifically for the series 8 Mazda RX7 FD3S – twin turbo. It’s a direct plug-in to the factory wiring and controls the factory twin turbochargers. For those converting to a single turbo, you can upgrade the ignition system to direct fire. VE and automatic staging gives you the ability to change injectors without manually working out when the secondary injectors need to be engaged.
Features of This ECU

• Built in 4-bar MAP sensor to replace the factory 2.5 bar sensor.
• VE tuning to simplify injector upgrades and simplify staging
• Easy to use software
• Plugs into factory wiring
• Compatible with many third party dashes and devices
• Full closed loop operation
• Flex fuel capable
• Compatible with standard porting, extend, bridge and peripheral porting

• Control over factory twin turbochargers
• Ability to upgrade to direct fire operation (4 ignition coils)
• Ability to upgrade crank trigger

Special Features

• This ECU also supports all the functions of the 440 ECU, however for advanced functions such as traction control, additional wiring and/or sensors will be necessary:
• Flex fuel function – fill it up with gas/petrol or any ethanol concentration
• Adaptive fuel control (self tuning) – reduces dyno time
• Traction control function
• Serial input for wideband O2 sensors (we recommend the MTXL)
• Serial output for communication with dashes and dataloggers (we recommend the Race Technology units)

GReddy Blow Off Valves are easily adjustable to eliminate compressor surge and preventing premature boost leakage, while increasing boost response between shifts. Each valve is made of durable cast and billet aluminum frame and the valve to diaphragm ratio provides performance that cheap piston types cannot offer. The spring stiffness adjustment screw and the three different models give the GReddy user the option to match vehicles with mild upgrades to heavily tuned engines
The Type FV
The Brand New GReddy FV has the latest Floating Valve technology.The unique “floating valve” design incorporates a revised adjustable dual spring system, while retaining the advantages of the previous models push valve structure and diaphragm control. The improved design makes spring preload setting less dependant on the idle, while providing increased response, valve travel, flow and resistance to premature valve lift under all conditions.
The new GReddy FV BOV retains the same mounting, outlef and position as previous GReddy Type RS and Type RZ models, making retrofitting the new type FV to existing applications possible.

The new PRofec is compact, powerful and easy to use. The large OLED Display, with the simple two-button / rotary-dial control, made for intuitive operation.

An ultra slim controller can display in digital, bar-graph, or graphical modes and can be rotated 180 degree for installation with the included adjustable mount or flush mounted.


By separating the display and control unit in the driver’s compartment, from the engine compartment-mounted, waterproof, sensor unit, it makes installation straightforward.

Only one thin harness is required to be routed through the firewall. The combination of the new 300kPa (43.5psi) integrated pressure sensor, the more compact solenoid valve and faster ECU processer, provide quicker response and the most stable boost curves yet.


The PRofec also maintains popular features like, Lo, Hi, Scramble boost presets, last-boost display, peak-hold recall, warning alert and safety limiter. The next evolution of the GReddy PRofec line of electronic boost controllers is here!

Thanks to our close association with the new UK distributor of Goopy Performance products Essex Rotary can now offer this superb proven more durable alternative to the standard Mazda Apex Seals.

Goopy Apex seals have become renowned for their reliability by withstanding up to 50psi in Drag Racing and still not failing and have even withstood detonation that the Mazda Apex seal could only dream of.

This makes these High Performance Apex seals not only ideal for any N/A, Turbo or Supercharged RX-7 but also ANY standard or tuned REW or 13bt engine .

Also available for the RX-8 engines these seals can be included in your Essex Rotary engine rebuild upon request at a small additional cost.

Sold at a set of 6 complete seals these will easily replace the stock apex seals found in all series 4- series 8 RX-7 engines.

Goopy 2 mm apex seals are .075″ (1.905mm) thick and you should be able to slide a .0015″ feeler gauge into the rotor apex slot with a new apex seal in place.

Goopy Performance 13B 2 mm oversized apex seals measure .078″ +/- .001″ (1.981mm +/- 0.025mm). If your rotor slot measures .077 – .078″, then you may benefit from our oversized 2 mm seals which will allow you to re-gain the .0015 suggested clearance.

If your gap with the seal in place measures .002-.005″ it is still usable, but keep in mind that tighter clearances means greater sealing characteristics.
