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.

GoopyLogo270w

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.

GoopyApexSeals420w

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.

Due to their increased popularity please allow up to 21 days for delivery

This Awesome Assembly Lube is used on all our engine rebuilds here at Essex Rotary, It makes the assembly of tight fitting close tolerance parts a breeze while still offering excellent protection for parts like stationary gears on initial start up.

Here is what Royal Purple have to say.
Max-Tuff is an ultra-tough, synthetic lubricant. It’s designed for engine builds and repairs. Max-Tuff utilizes unique, synthetic molecules that adhere to metal surfaces to create a formidable, load-bearing physical barrier between surfaces. This minimize the metal-to-metal contact and wear in boundary lubrication conditions, and provides excellent protection against rust and corrosion of both ferrous and nonferrous metals.

PERFORMANCE ADVANTAGES
  • Greater wear protection
  • Clean, efficient equipment
  • Extends equipment life
  • Compatible with conventional mineral and synthetic oils
  • Non-foaming
  • Outstanding rust / corrosion protection
  • High temperature service capability

Mazda 12A/13B Engine Twin V-belt Alternator Pulley
GFB lightweight pulley kits are made from aircraft-grade 6061-T6 aluminium and offer faster acceleration through significant weight reduction on the crankshaft. The effect is similar to a lighter flywheel, and the car feels more lively and willing to rev.

Most of our kits are underdriven, which means the accessories are driven slightly slower to reduce parasitic losses. It should be noted that our underdrive pulley kits do NOT adversely affect the operation of the accessories. If they did, we would not sell them!
Lightweight Alloy Pulley
  • Improved throttle response and acceleration through significant reduction of rotating mass
  • Engine feels more free-revving
  • Under-driven kits offer more power through reduction of parasitic losses from the accessories with NO adverse affects on their operation
  • Suitable for Sa22c, FB3s and FC3s Engine setups.
Compatible with both 12a and 13b Engine that run the old style V Drive Belts.

The rotor bearings are manufactured with a deep groove for additional oil storage and offer an additional .0005" (approximate) clearance. These bearings can be used in 1973 and earlier engines by grinding off the indexing tab.

Competition bearings have 0.01 inch deeper oil groove and provide 0.0005 inch more clearance than stock bearings. Thinner overlay material improves bearing service life.

These bearings are special order only and can take up to 6 weeks for delivery. They are sometimes out of stock at Mazda HQ Japan so can take longer. we would recommend ordering your competition bearings early to avoid disappointment.

Genuine Mazda Factory Race Part
Use in place of stock rear bearing. 3-window type. Recommended for any engine used at 8000 rpm and above. Increases oil flow to the inside of eccentric shaft and to rotors.

If you are installing this bearing in to a Manual RX-7 FD3s of 231ps RX-8 Rear Stationary Gear we would recommend getting an indexing groove cut in to the rear face of the stationary gear in order to locate and hold this bearing correctly. The location should be in the same place as that found on Auto Rear Stationary gears and those earlier then the FD3s. Stationary gears from the Automatic FD3s and RX-8 including the 192ps manual RX-8 should have this indexing groove in them already.

These bearings are special order only and can take up to 6 weeks for delivery. They are sometimes out of stock at Mazda HQ Japan so can take longer. we would recommend ordering your competition bearings early to avoid disappointment.

    Pineapple Racing Solid Dowel Pins
    • Helps prevent cracking the plates from hp loads or “ping” (esp. important in the 20B and Series 5 & earlier turbo engines)
    • Spreads the load across the length of the engine.
    • Helps to insure a true engine centerline which reduces engine failure and increasing bearing life
    • Using an external oil line provides a more even oil pressure to the main bearings
    • Low cost, easy installation
    • Available for: 12A, 13B and 20B (12a and 20b Special Order)
    • Custom lengths available (Special Order)
    Pineapple Racing Solid Dowel Pins provide an easy, cost effective aid to hp and “ping” loads causing plate cracking or engine damage from loss of clearance from engine flex. Our super strong proprietary material has been meticulously machined to provide what we feel are the most accurate and consistently machined solid dowel pins on the market. The O.D. is accurate to 50 millionth’s! That’s 0.00005”. We “lightly” tapped one end for use with a Dowel Pin Puller.

    Replace just the lower dowel pins helps to insure your engine’s centerline remains true. It is a great update requiring no machining.

    Replace both lower and upper dowel pins for the maximum improvement. Replacing the upper dowel pins requires the installation of an external oil feed line to the front main oil galley to replace the OEM galley in the OEM dowel pins. Our Oil Pedestal Adapter kit makes this a simple job that can be done with simple hand tools and an electric drill.

    High horsepower and the shock loads from “ping” put a tremendous load against the rotor housings. The load deflects the rotor housings outwards, pushing the dowel pin with them. The dowel pins are retained by their fit into the cast iron plates. If the loads are too high, the upper dowel pin can cause the plate(s) to crack. Additionally, since the upper dowel pins are also used as an oil galley, a massive oil leak is also possible. The OEM 20B is especially prone to this type of damage,  and with the price of the “thick” center plate near $1800us, preventing this type of damage pays for itself.

    The Pineapple Racing Oil Pedestal Adapter is a stylish, Nickel plated rotor shaped adapter. It easily installs between the existing oil filter pedestal and the rear plate. It features a ¼”NPT port for an external oil line and an 1/8” NPT port for oil pressure or oil temperature.

This is Pineapple Racing's exclusive Heavy Duty Water Seal kit. Pineapple Racing tested these seals for over 7 years in numerous street and track cars before offering them to our customers. They have proven to be a significant upgrade over the stock water seals. Pineapple Racing use them in all their 5-year warranty motors.
Also, these seals are re-usable if you need to reopen the motor to freshen it, as long as the mileage is not too high or the engine too overheated. In other words, if you make a mistake and blow up your engine or perhaps improperly clearance the seals or whatever, these seals can be removed, allowed to "rest" for about 30 minutes and be reused when you put the engine back together. Stock water seals must be disposed of when freshening an engine, even with just a couple heat cycles.

Kit includes
  • Water jacket o-rings
  • Front cover o-ring (and backup washer, if needed application dependent)
  • Dowel o-rings
  • Rear stationary gear o-ring
  • Oil pedestal o-rings or Gasket (depending on application).
  • Oil Metering Pump "O" Ring
  • Dowty Washer Set (Tension Bolt Washers)
Please note this kit will fit 12a and 13b engines build between 1974 and 1984

Racing Beat's dyno-proven Power Pulse Air Filter Assembly, for all 1971-85 Stock Carburettor Bodies, is designed specifically for performance. While the assembly uses the same Racing Beat foam air filter element that fits the stock canister, the design of the Power Pulse canister both improves air flow into the carburettor and limits the introduction of dirt particles into the filter element.

The spun aluminium canister pieces are powder-coated white for added durability. There is no provision for emission control valve hose/air pump hose connections on this assembly; however, there is a position available to connect a crankcase breather tube if needed.

The Racing Beat-designed Foam Air Filter Element for all 1971-85 Rotaries consists of a polyurethane foam over a metal screen form that interchanges exactly with the stock element. The foam element can be re-used by periodically cleaning in solvent and re-oiling.

While the element offers no significant increase in air flow when compared to a clean, stock paper element, as the paper element collects dirt its air flow capacity decreases dramatically while the foam element is nearly unaffected.

We offer the extremely popular Racing Beat-modified High Performance Holley Intake System Kit for 1976-1985 12A Stock (non-ported) engines.

Racing Beat's High Performance Holley Intake System Kit has proven over the years to be an extremely reliable carburetor upgrade, with very "streetable" engine smoothness and drivability characteristics. Fuel economy is comparable to the stock carburetor under similar driving conditions.

Complete Ready-to-Install Kit
One of most significant benefits of this complete ready-to-go kit is that is takes all the guesswork, trial-and-error, and frustration out of attempting to assembly your own intake kit! We've taken over 40 years of our rotary engine experience and know-how and combined it for you in this complete, ready-to-install kit. Our intake kits has been thoroughly developed and tested using our in-house engine dyno to ensure maximum performance for each specific engine application.

Rotary-tuned By Racing Beat
The heart of each intake system is a performance-proven 4-barrel Holley carburetor. Depending on the requirements of each specific application, the carburetor is disassembled by Racing Beat's carburetor technicians then reworked, retuned, and reconfigured specifically for use with a designated rotary engine application. This process is not a simple "re-jetting" project, but a complex series of steps requiring machining, drilling and reconfiguring of the main and metering bodies, adjustment of the float bowls, and complete replacement of all jets. Each application has been fully developed and tested on our in-house dyno facility to ensure maximum performance.

Each comprehensive package includes a Racing Beat cast-aluminum high-rise intake manifold with a vacuum source for power brakes, a Racing Beat-modified Holley carburetor (465 CFM), foam air cleaner and canister assembly, throttle and metering oil pump linkages, and appropriate gaskets. All emissions control fittings are eliminated. This carburetor includes a vacuum-operated choke.

Performance
When installed on a 1976-78 RX-3 or a 1979-85 RX-7 12A engine, this kit increases engine output by approximately 20 HP with the stock exhaust system. However, for increased performance gains we strongly recommend the installation of an exhaust header/presilencer/Power Pulse Muffler combo (10+ HP) or an open exhaust (15+ HP) - resulting in total performance gains of between 30-35 HP depending on your specific intake/exhaust configuration..

The carburetors and manifolds used in these Holley kits are also available separately in the "Holley Components" section.

Note: Installation of this kit requires use of a high delivery fuel pump kit delivering 6 psi @ 20 gph.
