Component And Trim Specification Guide For The 1991 Nissan 240sx Interior
The 1991 Nissan 240SX, a popular sports coupe renowned for its balance, handling, and modification potential, featured a surprisingly diverse array of interior components and trim options. This guide delves into the specifics of these elements, providing a detailed look at the materials, construction, and variations found within this iconic vehicle.
Seating & Upholstery
The seats in the 1991 240SX were offered in several styles, largely dependent on the trim level (base, SE, or LE). Understanding these differences is crucial for restoration and modification purposes.
Base Model
The base model 240SX typically featured cloth upholstery. The fabric was a durable, though somewhat basic, woven material. Color options were limited, often consisting of shades of gray or black. The seat design itself was relatively flat, offering minimal bolstering for lateral support. The frames were steel and generally well-built for the era, but susceptible to rust in humid climates.
SE Model
Stepping up to the SE model brought improvements in both material and design. The upholstery was still cloth, but the weave was generally tighter, and the texture more premium. Importantly, the SE seats featured improved bolstering on both the seat bottom and backrest. This provided a significantly enhanced driving experience, especially during spirited driving. Color options were expanded slightly. Often, SE models received a two-tone color scheme. The frame construction remained similar to the base model, but the padding and internal supports were upgraded.
LE Model
The LE (Luxury Edition) represented the pinnacle of 240SX interior appointments. The most significant upgrade was the introduction of leather upholstery. The leather used was generally a "split" or "corrected grain" leather, rather than a top-grain hide. This means it was a lower grade of leather that was sanded and treated to create a uniform appearance. While not as supple as higher-quality leathers, it proved durable and relatively easy to maintain. The LE also included upgraded door panel inserts, often with leather or suede accents. The seat design mirrored the SE's bolstered shape.
Beyond the material, the seat construction itself is noteworthy. All 240SX seats featured a spring-based suspension system underneath the padding. This provided a degree of comfort and prevented the seats from becoming overly stiff. The seat tracks were adjustable, allowing for fore-aft movement. The driver's seat often included height adjustability, although this feature was not universally present across all models and years.
Understanding the seat frame construction is vital for anyone considering aftermarket seat installations. The mounting points and dimensions are unique to the 240SX, requiring either custom brackets or modification of existing aftermarket seats.
Dashboard & Trim Panels
The 240SX dashboard was constructed primarily of molded plastic. The design was functional and driver-focused, with clear instrumentation and easily accessible controls.
Dashboard Materials
The main dashboard shell was molded from ABS (Acrylonitrile Butadiene Styrene) plastic. This material offered a good balance of impact resistance and heat resistance. However, over time, exposure to UV radiation could cause the plastic to become brittle and prone to cracking. The dashboard surface was typically finished with a textured coating to reduce glare. Color options were limited to shades of gray, black, and occasionally a dark blue.
Instrument Cluster
The instrument cluster housed the speedometer, tachometer, fuel gauge, and temperature gauge. The gauges were analog, illuminated by incandescent bulbs. Higher trim levels might have included additional gauges, such as a boost gauge (for turbocharged models, if aftermarket fitted). The instrument cluster lens was made of clear acrylic plastic. The gauge faces themselves were printed with clear, easy-to-read markings.
Center Console
The center console housed the radio, climate controls, and gear shift lever. It was also molded from ABS plastic, often with a similar textured finish as the dashboard. The specific design of the center console varied slightly depending on the trim level and whether the car was equipped with a manual or automatic transmission. The climate controls were either manual sliders or, on some higher-end models, electronic controls with a digital display.
Door Panels
The door panels were constructed from a combination of plastic and upholstered inserts. The plastic portion of the door panel typically matched the color of the dashboard. The upholstered inserts were often cloth or, in the LE models, leather or suede. The door panels also housed the window switches, door lock switch, and door handle. The quality of the plastic used in the door panels was generally lower than that of the dashboard, making them more prone to cracking and warping.
Pay close attention to the condition of the door panels when evaluating a 240SX. Cracked or damaged door panels are a common problem and can be difficult to repair or replace.
Interior Trim & Accents
Small details often separate different trims and mark the passage of time. The interior trim and accents provide a finishing touch to the cabin.
Steering Wheel
The steering wheel varied depending on the trim level. Base models typically featured a simple plastic steering wheel. SE models often included a leather-wrapped steering wheel, providing a more premium feel. Some LE models had a thicker, more ergonomically designed steering wheel. The steering wheel hub was connected to the steering column via a series of splines. Aftermarket steering wheel adapters are readily available for the 240SX, allowing for the installation of a wide variety of aftermarket steering wheels.
Shift Knob
The shift knob, like the steering wheel, varied depending on the trim level and transmission type. Manual transmission cars typically had a simple plastic shift knob. Some SE models included a leather-wrapped shift knob. Automatic transmission cars had a different style of shift knob with a button or lever to engage the gear selector. Aftermarket shift knobs are a popular modification for the 240SX, with a vast array of styles and materials available.
Carpeting
The carpeting in the 240SX was a relatively low-pile, durable material. Color options were limited to shades of gray or black. The carpeting was typically molded to fit the contours of the floor pan. Over time, the carpeting could become stained or faded, particularly in areas exposed to sunlight. Replacement carpeting kits are available, allowing for a refresh of the interior.
Sound System
The factory sound system in the 1991 240SX was relatively basic. Base models typically had a simple AM/FM radio. Higher trim levels might have included a cassette player or, in some cases, a CD player. The speakers were typically located in the doors and rear deck. The sound quality was generally adequate for the time, but modern aftermarket sound systems offer a significant improvement. Replacing the factory sound system is a common modification for 240SX enthusiasts.
Common Problems & Restoration Tips
Age and use have taken their toll on many 1991 240SX interiors. Here are some common issues and tips for restoration:
- Cracked Dashboard: A very common problem. Dashboard covers are available, or a replacement dashboard can be sourced (though finding one in good condition can be challenging).
- Torn Upholstery: Seat covers are a simple solution. Alternatively, professional reupholstering can restore the seats to their original condition. Leather seats will require specific cleaning and conditioning products.
- Faded Carpeting: Replacement carpet kits are readily available and relatively easy to install.
- Broken Trim Pieces: Sourcing replacement trim pieces can be difficult, but online forums and junkyards are good resources.
- Sticky Door Handles: A common issue caused by dried-out grease. Disassembly and cleaning/regreasing can often resolve this problem.
When restoring a 240SX interior, it is important to use high-quality materials and techniques. Attention to detail will ensure that the interior looks and feels like new.
In conclusion, the 1991 Nissan 240SX interior, while not lavish, was thoughtfully designed and constructed. Understanding the nuances of the different trim levels and materials used is essential for anyone seeking to restore or modify this iconic vehicle.
