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 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
Please allow around 28 days for delivery if not in stock.

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.

NOT ALL 13B ENGINES RUN 3MM APEX SEALS, PLEASE CHECK YOUR APPLICATION BEFORE ORDERING.
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 13b but also ANY standard or tuned 13b engine running 3mm seals .
Goopy Performance recommend .0015″ of clearance between the apex seal and the rotor slot for all applications, boosted or naturally aspirated.
3 mm 13B Goopy Apex Seals are .115″ (2.921mm) thick, and you should be able to slide a .0015″ feeler gauge into the rotor apex slot with a new apex seal.
Goopy oversized 3 mm seals measure .118″ + / – .001″  (2.997mm  +/- 0.025mm). If your rotor slot measures .018″ – .020″, you may benefit from our oversized 2 mm seals which will allow you to re-gain the .0015″ suggested clearance.
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 some factory 13b engines or builds with 3mm machines slots.
Due to their increased popularity please allow up to 21 days for delivery

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.

The Mazda Factory Race (MFR) rotor bearings for all 12A & 13B engines are the best bearings available of engine operation near or above 8500 RPM. 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.
