Part Number And Sourcing Guide For The 1995 Nissan 240sx

The 1995 Nissan 240SX, a beloved sports coupe cherished for its responsive handling, tunable engine (the KA24DE), and iconic drift-ready status, remains a popular choice among automotive enthusiasts. Restoring or maintaining a 240SX often requires locating specific parts. This guide provides valuable part numbers and sourcing information to help you keep your 1995 240SX running smoothly.

Engine Parts & Sourcing

The 1995 240SX came equipped with the KA24DE engine, a 2.4-liter inline-four cylinder. Here's a breakdown of common engine parts and where to find them:

Essential Engine Components

Head Gasket: This crucial part seals the cylinder head to the engine block. A blown head gasket can lead to overheating and engine damage. Part numbers can vary depending on the manufacturer, but a common reference is Fel-Pro HS9861PT. Sourcing: Check reputable online retailers like RockAuto, Summit Racing, and Amazon. Local auto parts stores like AutoZone, Advance Auto Parts, and O'Reilly Auto Parts also carry head gaskets.
Timing Chain Kit: The timing chain synchronizes the crankshaft and camshaft. Over time, it can stretch or break, causing severe engine damage. A complete timing chain kit typically includes the chain, sprockets, and tensioner. Consider a reputable brand like Cloyes or Aisin. Sourcing: Online retailers specializing in performance parts and Japanese car components are your best bet. Check forums dedicated to the 240SX; members often recommend reliable suppliers.
Water Pump: The water pump circulates coolant through the engine to prevent overheating. A failing water pump can lead to engine damage. Always replace the water pump when replacing the timing chain. A common part number to search is Aisin WPN-019. Sourcing: Similar to head gaskets, online retailers and local auto parts stores are good sources.
Thermostat: The thermostat regulates engine temperature. A faulty thermostat can cause overheating or poor fuel economy. A standard replacement thermostat is typically around 170-180 degrees Fahrenheit. Part numbers vary by manufacturer. Sourcing: Your local auto parts store can easily provide a compatible thermostat.
Spark Plugs: Essential for ignition. NGK BKR5E-11 is a commonly recommended spark plug for the KA24DE. Sourcing: Widely available at auto parts stores and online.
Distributor Cap & Rotor: These components distribute the spark to the correct cylinders. Over time, they can wear down, causing misfires. Sourcing: Local auto parts stores or online retailers like RockAuto.
Oxygen Sensor (O2 Sensor): Monitors the exhaust gases and helps the engine control unit (ECU) adjust the air/fuel mixture. Replacement may be necessary for optimal performance. Part numbers vary depending on upstream or downstream placement. Sourcing: Online retailers are often the most competitive in price, but local auto parts stores can offer immediate availability.

Sourcing Tips for Engine Parts

OEM vs. Aftermarket: Original Equipment Manufacturer (OEM) parts are made by the original manufacturer (Nissan) and are generally considered the highest quality, but they are also the most expensive. Aftermarket parts are made by other companies and can offer a more affordable alternative. Research brands carefully to ensure quality.
Used Parts: Consider used parts from reputable sources, such as junkyards specializing in Japanese vehicles. This can be a cost-effective option for certain components, but inspect the parts carefully before purchasing.
Online Forums & Communities: 240SX online forums and communities are invaluable resources for finding parts and getting advice from other owners.

Chassis & Suspension Parts & Sourcing

The 240SX's handling prowess is partly due to its well-designed chassis and suspension. Maintaining these components is critical for safety and performance.

Key Chassis & Suspension Components

Struts/Shocks: Worn struts or shocks can negatively impact handling and ride quality. KYB GR-2/Excel-G struts are a popular choice for a comfortable and responsive ride. Sourcing: Online retailers specializing in suspension components and performance parts are the best options.
Control Arms: These components connect the suspension to the chassis. Bushings in the control arms can wear out over time, leading to sloppy handling. Consider replacing the entire control arm or just the bushings. Sourcing: Online retailers and some auto parts stores. Aftermarket control arms with adjustable camber and caster are popular upgrades.
Tie Rod Ends: These connect the steering rack to the wheels. Worn tie rod ends can cause loose steering and uneven tire wear. Sourcing: Easily found at local auto parts stores and online retailers.
Ball Joints: Allow the wheels to pivot. Failing ball joints can be dangerous. Sourcing: Local auto parts stores and online retailers.
Sway Bar Bushings & End Links: These components help to reduce body roll during cornering. Replacing worn bushings and end links can improve handling. Sourcing: Local auto parts stores and online retailers. Polyurethane bushings offer increased stiffness and durability.
Wheel Bearings: Allow the wheels to rotate smoothly. Worn wheel bearings can cause noise and vibration. Sourcing: Local auto parts stores and online retailers.

Sourcing Tips for Chassis & Suspension Parts

Inspect Thoroughly: Before purchasing any suspension component, carefully inspect it for damage or wear.
Consider Upgrades: If you are looking to improve the handling of your 240SX, consider upgrading to aftermarket suspension components, such as adjustable coilovers, sway bars, and control arms.
Professional Installation: Suspension work can be complex and requires specialized tools. If you are not comfortable working on your own suspension, it is best to have it done by a qualified mechanic.

Brake System Parts & Sourcing

A properly functioning brake system is essential for safety. Maintaining your 240SX's brakes is crucial.

Essential Brake System Components

Brake Pads: These are the friction material that presses against the rotors to slow the vehicle. Part numbers vary depending on the type of pad (organic, semi-metallic, ceramic). Akebono is a popular brand for daily driving. Sourcing: Local auto parts stores and online retailers.
Brake Rotors: These are the metal discs that the brake pads clamp onto. Centric is often recommended. Sourcing: Local auto parts stores and online retailers. Consider slotted or drilled rotors for improved performance.
Brake Calipers: These house the brake pads and apply pressure to the rotors. If calipers are leaking or sticking, they need to be rebuilt or replaced. Sourcing: Local auto parts stores and online retailers. Rebuilt calipers are often a more affordable option.
Brake Master Cylinder: This supplies hydraulic pressure to the brake system. A failing master cylinder can cause a soft or spongy brake pedal. Sourcing: Local auto parts stores and online retailers.
Brake Lines: These carry brake fluid to the calipers. Over time, they can deteriorate and leak. Stainless steel brake lines offer improved performance and durability. Sourcing: Online retailers specializing in brake system components.

Sourcing Tips for Brake System Parts

Replace in Pairs: Always replace brake pads and rotors in pairs (both front or both rear) to ensure even braking performance.
Bleed the Brakes: After replacing any brake component, it is essential to bleed the brakes to remove air from the system.
Consider Upgrades: For improved braking performance, consider upgrading to larger brake rotors, calipers, and stainless steel brake lines.
