Widebody Conversion Options For The 1990 Nissan 240sx
The Nissan 240SX, particularly the S13 chassis produced from 1989 to 1994, is a beloved platform for drifting, time attack, and general street modification. One popular modification is a widebody conversion, allowing for wider wheels and tires, enhanced aesthetics, and improved handling. This article will delve into the various widebody options available for the 1990 Nissan 240SX, outlining their pros, cons, and installation considerations. We'll cover everything from bolt-on fender flares to full replacement quarter panels, giving you the information you need to make an informed decision for your project.
Understanding Widebody Types
Before diving into specific kits, let's categorize the common types of widebody modifications for the 240SX:
- Bolt-On Fender Flares: These are the simplest and most affordable option. They attach to the existing fenders and quarter panels, typically using rivets or screws. They offer increased width but often require cutting the original sheet metal underneath for proper tire clearance.
- Over Fenders: Similar to fender flares but generally larger and more aggressive in appearance. They also require cutting the original fenders.
- Full Replacement Quarter Panels/Fenders: These involve removing the entire original quarter panel or fender and welding in a wider, aftermarket replacement. This is the most involved option but offers the cleanest and most integrated look.
- Custom Metal Fabrication: This entails completely reshaping the existing fenders and quarter panels or creating entirely new ones from scratch. This is a highly skilled process typically left to professionals.
Bolt-On Fender Flares: A Budget-Friendly Option
Bolt-on fender flares are a great entry point into the widebody world. They are relatively inexpensive and can be installed with basic tools. However, they come with their own set of considerations:
Pros:
- Affordability: The least expensive widebody option.
- Ease of Installation: Can be installed with basic tools (drill, rivet gun, grinder, etc.).
- Reversibility: While requiring cutting of the original sheet metal underneath, the flares themselves can be removed. (Though the cut metal cannot be un-cut!)
Cons:
- Aesthetics: Can look "stuck-on" if not properly blended and integrated.
- Cutting Required: Cutting the original fenders and quarter panels is necessary for tire clearance, a point of no return.
- Durability: May be prone to cracking or damage if not properly mounted or if subjected to impacts.
- Fitment Issues: Fitment can vary widely between different manufacturers. Ensure you purchase from a reputable source.
Installation Considerations:
- Preparation: Clean and degrease the areas where the flares will be mounted.
- Test Fitting: Carefully test fit the flares before drilling any holes. Mark the locations for the mounting hardware.
- Cutting: Using a cut-off wheel or reciprocating saw, carefully cut away the excess material from the original fenders and quarter panels. Leave a small lip for structural integrity. Deburr (remove sharp edges) the cut metal.
- Mounting: Secure the flares using rivets, screws, or a combination of both. Consider using adhesive sealant between the flare and the body to prevent water intrusion.
- Finishing: Use body filler to blend the flares into the existing bodywork for a smoother appearance. This is crucial for a professional-looking finish.
Over Fenders: Going Bigger
Over fenders are essentially larger, more aggressive versions of fender flares. They offer significantly more tire clearance but come with similar challenges:
Pros:
- Increased Tire Clearance: Allows for very wide wheels and tires.
- Aggressive Aesthetics: Provides a more pronounced and aggressive look.
Cons:
- More Cutting Required: Requires even more extensive cutting of the original fenders and quarter panels.
- Fitment Challenges: Fitment issues can be exacerbated due to the larger size and more complex shapes.
- Integration Difficulty: Blending large over fenders seamlessly into the bodywork can be challenging.
Installation Considerations:
The installation process is similar to that of bolt-on fender flares, but with a greater emphasis on proper fitment and blending. You'll need to be very precise with your cutting and welding (if reinforcing) to ensure a clean and strong installation. Pay extra attention to panel gaps and alignment.
Full Replacement Quarter Panels/Fenders: The Professional Approach
Replacing the entire quarter panel or fender is the most demanding but also the most rewarding widebody option. This method involves cutting away the original sheet metal and welding in a new, wider panel. This allows for a much cleaner and more integrated look.
Pros:
- Cleanest Look: Provides the most seamless and integrated widebody appearance.
- Structural Integrity: If installed correctly, can maintain or even improve the structural integrity of the vehicle.
- Maximum Tire Clearance: Offers the greatest amount of tire clearance.
Cons:
- Highest Cost: The most expensive widebody option due to the cost of the panels and the labor involved.
- Requires Welding Skills: Requires significant welding skills and specialized equipment.
- Irreversible: A very invasive and irreversible modification.
- Potential for Rust: Improper welding or lack of rust protection can lead to corrosion issues.
Installation Considerations:
- Preparation: Remove the interior trim and any components that may be damaged by heat or sparks.
- Cutting: Carefully cut away the original quarter panel or fender, leaving a small flange for welding. Take measurements and document thoroughly.
- Test Fitting: Test fit the new panel multiple times to ensure proper alignment and fitment. Adjust as needed.
- Welding: Use a MIG (Metal Inert Gas) or TIG (Tungsten Inert Gas) welder to weld the new panel into place. Use *seam welding* techniques for the strongest bond. Tack weld frequently to avoid warping.
- Grinding: Grind down the welds to create a smooth surface.
- Bodywork: Use body filler to smooth out any imperfections and blend the panel into the existing bodywork.
- Rust Protection: Apply rust-preventative primer and sealant to all welded areas, both inside and out.
- Painting: Paint the new panel to match the rest of the vehicle.
Material Considerations: Fiberglass vs. Polyurethane vs. Metal
Widebody kits are typically made from fiberglass, polyurethane, or metal. Each material has its own advantages and disadvantages:
- Fiberglass: Lightweight, relatively inexpensive, but prone to cracking and shattering. Requires more prep work for a smooth finish.
- Polyurethane: More flexible and durable than fiberglass, but heavier and more expensive. Offers better impact resistance.
- Metal: The most durable and authentic option, but also the most expensive and requires significant fabrication skills. Often reserved for full replacement panels or custom work.
Choosing the Right Kit for Your 240SX
The best widebody option for your 1990 Nissan 240SX depends on your budget, skill level, and desired aesthetic. Consider the following factors:
- Budget: Bolt-on flares are the most budget-friendly, while full replacement panels are the most expensive.
- Skill Level: Bolt-on flares can be installed by most DIYers, while full replacement panels require advanced welding and bodywork skills.
- Desired Look: Choose a kit that complements the overall style of your car.
- Fitment Quality: Research the manufacturer and read reviews to ensure good fitment.
- Intended Use: A car primarily driven on the street may not need as aggressive a widebody as a dedicated drift car.
Final Thoughts
A widebody conversion can dramatically transform the look and performance of your 1990 Nissan 240SX. However, it's a significant undertaking that requires careful planning and execution. Be realistic about your skills and budget, and don't be afraid to seek professional help if needed. With the right approach, you can create a truly unique and eye-catching 240SX.
