The original rotary engine stand adapter plate.

Works for all 12A & 13B rotary engines.

Use this to bolt onto your current engine stand for easier use with the rotary engine. This is balanced, so you can turn your engine in the various positions needed to build your engine. You may also weld this adapter to the tube size to fit your stand for even easier use.

Our engine stand adapter is powder coated and comes with all the bolts/washers necessary to bolt to your stand.

Rotor Bearing Installation/Removal Tool - Designed By David Atkins in the Early 80's.

Easy to use with a hydraulic press, will not hurt the bearing, assures a perfect fit every time.

The stock mazda rotor bearing tool is about twice as expensive and doesn't work as well!

This coolant tester allows you to find coolant leaks in the engine before you install it. If you build many engines this will undoubtedly save you a lot of time.

This kit works on 1974 - Current rotary engines including Rx8 and 20B applications.

Other coolant tester kits don't come with everything you need to plug off all areas to perform the test, this comes with all you will need to test your coolant system.

When your rotary engine has no compression and broken apex seals are not the culprit then this might help remove carbon to free up your seals and springs in order to allow for increased compression.

• Improves starting and performance.
• Cleans dirty intake systems and spark plugs.
• Works inside and outside the engine.
• Recommended for carburetor and fuel injectors.
• Also removes gum, varnish and carbon deposits from engine exterior surfaces.

Directions:

Disconnect your ignition fuse, and spray the entire can into your intake and crank it a couple times to ensure that all 3 sides of each rotor are coated thoroughly. Let it sit for a couple hours then install your ignition fuse and start it up.

This should free up your apex seals if they are stuck in the compressed position with carbon. It may be necessary to install new spark plugs afterward if they are fouled out.

If you are not using the recommended NGK spark plugs for your specific year of engine then you will need to use this thin wall socket to install or remove your plugs.

13/16 Spark Plug Socket

This socket may crack while you are using it, do to its thin nature, but it will still do the job.

Effective outside diamter that goes into the housing is 0.977" (24.83mm).

Fits in 2mm slot.

This file is not exactly 2mm, it is slightly less to clean the 2mm slot.

Two tools in one!

The only real specialty tools you need from Mazda to work on rotary engines are a pilot bearing puller, and a dowel pin puller, both of them are quite expensive.

We have designed this one tool to do both jobs and save money. This tool is of great craftsmanship and is a work of art as much as a tool, and it really gets the job done!

Used to fix the threads on the flywheel end of the shaft if they get banged up.

This will fit earlier engines as well.

This bolts to the top two transmission bolts holes closest together on the intake side of the rear cast iron.

One side is fits the non-turbo teeth on the flywheel, flip it over to use the other teeth for the turbo flywheel.

This will not fit automatic Rx8 engines, unless maybe you used a huge stack of washers to line up the teeth, or got creative with the spacer; however this is not supported nor guaranteed to work.

Do not fit Rx8 Formula Mazda Flywheels.

This brush is refillable, and is great for getting into small places like corner seal, apex seal, and oil ring grooves on the rotors.

Twist the end of the handle to expose more or less bristles.

Don't forget to order brush bristle refills.

Includes one bristle set.

Refill bristles for the mini hand brush.
