What Problems Does the 1990 Mazda RX-7 Have?
The 1990 Mazda RX-7, like many rotary-engine cars, has a reputation for specific, though not insurmountable, long-term reliability concerns. The most significant and frequently reported issue revolves around the 13B rotary engine's apex seals. These seals, critical for compression, are susceptible to wear over time, especially if the engine is not properly maintained or is subjected to abuse. Symptoms of worn apex seals include loss of compression, hard starting, rough idle, and ultimately, engine failure. Regular oil changes with the correct type of oil and avoiding prolonged high-RPM operation without adequate cooling are crucial preventative measures. Overheating is another common problem, often stemming from aging cooling system components like radiators, hoses, and water pumps. Maintaining a clean and functional cooling system is paramount. Rust is also a prevalent concern for cars of this era, particularly in regions with harsh winters. Areas prone to rust include the wheel arches, rocker panels, and strut towers. Early detection and remediation of rust are vital to prevent structural integrity issues. While there weren't widespread recalls directly tied to catastrophic failures for the 1990 model year that fundamentally plagued the entire production run, individual components can fail due to age. Common electrical gremlins can also appear, such as issues with the power window motors, sensors, or the aging wiring harness. For the 1990 model year specifically, there weren't major widespread design flaws that were corrected in later FC models beyond general improvements to cooling and engine management that occurred throughout the FC generation. However, owners often report needing to replace vacuum lines, fuel injectors, and ignition components due to age. Despite these potential issues, with diligent maintenance and prompt attention to early warning signs, many RX-7s can remain reliable drivers, cherished for their unique character.
How long will the 1990 Mazda RX-7 last?
Estimating average mileage for a 1990 Mazda RX-7 is challenging due to its enthusiast appeal and the varying maintenance habits of owners. Well-maintained examples can easily exceed 150,000 miles, with some enthusiasts pushing their rotary engines to well over 200,000 miles. However, many have been driven less and stored, leading to lower mileage examples. The long-term durability is highly dependent on adherence to the rotary engine's specific maintenance needs. Neglect of apex seals, cooling system, or proper lubrication can lead to premature failure well before 100,000 miles. Conversely, meticulous care, including regular oil changes with appropriate oil, diligent cooling system checks, and mindful driving, can reveal the underlying robustness of the chassis and drivetrain. The rotary engine is the primary weak point over time if not properly managed, while the rest of the car generally holds up well for its age.
What Technology & Safety Features are Included?
The 1990 Mazda RX-7, being a sports car from the late 80s/early 90s, offers a relatively basic but driver-focused technology and safety suite by modern standards. Standard entertainment typically consisted of an AM/FM radio, often with a cassette player. Higher trims or optional upgrades might have included a more advanced stereo system with more speakers, sometimes even a graphic equalizer. Air conditioning was a common feature, though its effectiveness can vary with age. Power windows and power locks were standard on most trims, adding a touch of convenience. Technology was not a primary focus for the RX-7; rather, the emphasis was on driving dynamics. Driver-assistance features were virtually non-existent. There were no advanced cruise control systems, lane departure warnings, or automatic emergency braking. The primary safety features included seat belts, padded dashboards, and side-impact beams in the doors. ABS (Anti-lock Braking System) was available as an option on some models, particularly the Turbo II, which significantly improved braking control. In terms of crash-test ratings, official tests from the era, such as those conducted by the NHTSA or IIHS, are not as readily available or as comprehensive as they are for modern vehicles. However, the FC RX-7 was generally considered to have a reasonably robust chassis for its time, offering decent occupant protection in frontal and side impacts for its period. The convertible model, as is typical for convertibles, would likely have offered less structural protection than the coupe. The focus was on a sturdy unibody construction and crumple zones designed to absorb impact energy.
