Features:

Wankel Rotary Engine:

The main highlight of the Mazda RX-2 and RX-3 was the rotary engine, which was compact, powerful and smooth.

The RX-2 was often equipped with 12A or 10A engines.

The RX-3 was offered with an upgraded 12A or 13B for more power.

Compact Design:

The RX-2 was a more spacious sedan/coupe focused on comfort and dynamism.

The RX-3 was sportier, with an aggressive design and lightweight construction.

Handling:

These cars were lightweight, with excellent maneuverability due to rear-wheel drive and a sporty suspension setup.

Cult Status:

These models became popular among car enthusiasts and participated in races around the world, including rally competitions.

Available tuning allowed for improved power and dynamics.

Typical problems:

Rotary engine wear:

Due to the design of the rotary engine, the rotor seals (apex seals) often wear out. This leads to reduced compression and loss of power.

The engine is demanding of oil quality and regular maintenance.

Overheating:

The cooling system may not be efficient enough, especially under intensive use.

Old radiators and thermostats require modernization.

Body corrosion:

A typical problem for many classic Japanese cars from the 70s.

The greatest risk of corrosion is in the wheel arches, sills and underbody.

Electronics:

Over time, problems arise with the wiring, especially in older or modified cars.

Alternators and starters are also prone to failure.

Suspension and brakes:

Worn bushings and shock absorbers require regular inspection.

Brake mechanisms are outdated and need to be improved for modern use.

• Regular oil changes and use of original consumables.
• Monitoring of coolant and engine temperature.
• Protection of the body from corrosion using anti-corrosion agents.
• Careful engine tuning and compression check every 30-50 thousand km.
