Few automotive components carry the same level of prestige among rotary enthusiasts as a genuine Mazda 20B eccentric shaft.

The 20B engine itself has achieved near-mythical status in the automotive community. Produced in limited numbers and primarily found in the Eunos Cosmo, the 20B remains one of the most advanced and desirable rotary engines ever manufactured by Mazda.

This 20B Eccentric Shaft – Decorative / Rare 3-Rotor Item showcases the engineering that helped establish the 20B as one of the most respected rotary platforms ever created.

Custom Project Potential

Many rotary enthusiasts transform genuine eccentric shafts into custom creations such as:

• Table bases
• Trophy displays
• Desk ornaments
• Automotive artwork
• Motorsports memorabilia
• Feature pieces for engine rooms

Because every genuine 20B component has its own history, these projects often become highly personal tributes to rotary culture.

Preserving Rotary History
