Mazda R100 Parts Catalog – Factory OEM Parts Breakdown for Coupe & Sedan

You want to restore a Mazda R100. You order a water pump. It doesn’t fit. The supplier shrugs. You eat the shipping. I’ve seen it a hundred times. Without the right part number, you’re gambling. This is the Mazda R100 Parts Catalog – 609 pages of factory-issued part numbers direct from Toyo Kogyo Co., Ltd., the people who built the rotary. Not a reprint, not a third-party compilation. A genuine scan of the original Parts Catalog for the R100 coupe and sedan. If you can’t find a part in here, either it was never made or you’re looking at the wrong model.

This catalog covers every export variation: France, West Canada, England, Okinawa, USA emission-controlled models, Arctic spec for Finland and Norway. Right-hand drive, left-hand drive. T-type dashboard, plain type, S-type. The model numbers alone fill two pages. You get the exploded views and the part numbers. That’s it – no service procedures, no torque specs. For those you need the service manual. But for ordering the correct piece of metal or plastic, this is the only source you can trust.

609 Pages of Factory-Issued Part Numbers

Don’t let the thickness fool you – every page carries weight. The catalog starts with a “How to Use This Parts Catalog” guide that explains the model numbering system. For example, model 2061 is a Mazda R100 Sedan with a plain-type dashboard, left-hand drive, destined for France. 2125 is a coupe with the T-type dashboard, general export model. If you skip this step, you’ll order parts meant for the wrong dash or the wrong emissions setup. I’ve done it. It hurts. The catalog lists part numbers for the rotary engine (M10A-4, M10A-E), the body panels, the interior trim, the suspension, the brakes. All organized by section. You can’t guess your way through a rotary rebuild – the apex seals alone have different part numbers depending on engine series.

How to Use This Parts Catalog: Model Identification First

Before you flip to any section, find your exact model number. The catalog dedicates pages 1-4 to listing every variant. Page 1 shows the sedan models: 2061, 2062, 2063, 2064. Page 2 starts the coupe line: 2112 Arctic spec, 2113 for West Canada, 2123 RHD general export, 2124 for Okinawa, 2125 general export LHD, 2328 for USA emission-controlled. If your car is a 1970 R100 coupe sold in California, it’s probably 2328 or 2339. Match that number to the parts list that follows. The catalog uses a simple numbering system – each part image references a number that corresponds to a table with the part number, description, and quantity. There’s no guessing. You just need to read the legend at the top of each section. Every section header tells you which model it applies to. Pay attention to the asterisks and notes – they flag parts that differ between LHD and RHD or between dashboard types.

Model Variations: Coupe vs Sedan, LHD vs RHD, Emissions

The R100 was sold in so many configurations that one catalog has to cover them all. The coupe got the T-type dashboard in most export markets; the sedan got the plain-type or the S-type. Arctic spec cars (2112 for Finland & Norway) got additional cold‑start hardware. USA emission-controlled models (2328, 2329) had different carburetor and exhaust components. Right-hand drive models (2063 for England, 2123 general export) have steering and pedal boxes flipped. The catalog keeps them straight. You’ll see notes like “Niet Inported” (Not Imported) for some variants – that means the part wasn’t used on that particular model. Don’t order a plain‑type dashboard part for a T‑type car; the catalog tells you the difference up front. If you’re restoring a car that was originally sold in Europe, the catalog lists the French, English, and Scandinavian specific parts. For a true OEM restoration, this is the bible.

Authenticity: Why Aftermarket Catalogs Fall Short

Aftermarket parts catalogs often combine multiple years and models into one generic listing. They miss the small differences – the length of a brake line, the shape of a firewall grommet, the number of mounting holes on a body panel. This is the factory document. Toyo Kogyo printed it for their dealers. The part numbers are the same ones stamped on the original boxes. I’ve seen a universal catalog list a water pump for “Mazda R100 1970-71” that was actually a 1972 RX‑2 pump. Wrong. This catalog lists the pump by model number and engine type. If you need to cross-reference a part to the service manual, the part numbers match exactly.

FAQ – Common Questions About the R100 Parts Catalog

Does this catalog include the engine parts (rotor housings, apex seals, etc.)?

Yes. The catalog covers the complete M10A rotary engine – housings, side plates, internal seals, even the carburetor and intake manifold.

Are there torque specifications or service procedures in this catalog?

No. A parts catalog only lists part numbers and assembly diagrams. There are no torque specs, bolt tightening sequences, or diagnostic steps. For those, you need the factory service manual – we have that separately. Don’t try to rebuild an engine using only a parts catalog; you will strip threads and destroy seals. I’ve seen it.

Can I use this for a 1970 Mazda R100 coupe with right-hand drive?

Yes. The catalog includes RHD models (e.g., 2123 for general export, 2063 for England). Look up your model number on page 4, then find the corresponding parts sections. The steering column, pedal assembly, and dashboard parts will be specific to RHD.

Is this a reprint or a copy of the original?

It is a high-resolution digital scan of an original Toyo Kogyo Parts Catalog. No reprints, no photocopies. You get the exact pages the dealer used.

After 28 years of twisting wrenches, I’ve learned one thing: the right part number is half the battle. The other half is having the patience to look it up. This catalog gives you the numbers. Stop guessing. Order the right piece the first time. Access the Factory Manual now.
