Detailed Explanations

1990: As the inaugural year, the 1990 Plymouth Laser is a piece of DSM (Diamond Star Motors - the joint venture between Chrysler and Mitsubishi) history. While it offers a raw, unfiltered driving experience, it's crucial to be aware of potential early production issues that might have been ironed out in later years. These can range from minor trim quirks to more significant mechanical gremlins. Thorough inspection is key if you're considering a 1990 Laser.

1991: Building upon the foundation of the 1990 model, the 1991 Plymouth Laser saw minor improvements and refinements. Parts availability is generally good for this year, making maintenance and repairs relatively straightforward. However, it's still susceptible to the common DSM-related issues that plagued these cars, such as turbocharger problems, ECU capacitor failure, and crankwalk (especially in the manual transmission models).

1992: The 1992 Plymouth Laser is often considered one of the better years in the Laser's production run. It received suspension upgrades that improved handling and ride quality. Some trims also featured improved interior materials, enhancing the overall driving experience. However, like other DSM cars, it's still prone to rust in regions with harsh winters and salted roads.

1993: By 1993, the Plymouth Laser had undergone some subtle styling refinements, giving it a slightly more modern appearance. As these cars age, their prices may be more attractive, making them a potentially good value for budget-conscious buyers. The primary concern with 1993 models is age-related wear and tear. Components like rubber hoses, seals, and bushings will likely need replacement or have already been replaced.

1994: The 1994 Plymouth Laser marked the end of the Laser's production. It's the rarest model year, and finding one in excellent condition can be a challenge. However, a well-maintained 1994 Laser could be the best of the bunch, benefiting from all the improvements and refinements made throughout the model's lifespan. Expect to pay a premium for a pristine example.

Common DSM Issues

The term "DSM" refers to the Diamond Star Motors vehicles, which include the Plymouth Laser, Eagle Talon, and Mitsubishi Eclipse. These cars share many common components and are often grouped together when discussing potential problems. Here's a breakdown of some of the most prevalent issues:

  • Turbocharger Problems: The turbocharged models were prone to turbocharger failure, especially if not properly maintained or if driven hard without adequate cool-down periods. Look for signs of oil leaks, excessive smoke, or unusual noises from the turbocharger.

  • ECU Capacitor Failure: The electrolytic capacitors in the ECU (Engine Control Unit) can fail over time, leading to various engine management problems. Symptoms include erratic idling, stalling, and difficulty starting. This issue is often repairable by replacing the capacitors.

  • Crankwalk: Crankwalk is a catastrophic engine failure that occurs when the crankshaft develops excessive end play, eventually leading to damage to the bearings and connecting rods. This is more common in manual transmission models and can be exacerbated by aggressive clutch use. Listen for a distinct knocking sound from the engine, especially when the clutch is engaged or disengaged.

  • Rust: Like many cars from the early 1990s, the Plymouth Laser is susceptible to rust, particularly in areas with harsh winters and salted roads. Common rust spots include the rear quarter panels, rocker panels, and floor pans. Thoroughly inspect these areas for any signs of rust before purchasing a Laser.

  • Boost Creep: This occurs when the turbocharger boost pressure exceeds the intended level, often due to modifications or a malfunctioning wastegate. Boost creep can lead to engine damage if not addressed.

Evaluating a Used Plymouth Laser

Before purchasing a used Plymouth Laser, it's essential to perform a thorough inspection and ask the right questions. Here's a checklist to guide you:

  • Exterior: Check for rust, dents, and paint damage. Pay close attention to the common rust spots mentioned earlier. Ensure that all lights and signals are working properly.

  • Interior: Inspect the seats, carpets, and dashboard for wear and tear. Test all the electrical components, including the windows, locks, and radio. Check for any signs of water leaks, which can indicate a damaged sunroof or weather stripping.

  • Engine: Listen for any unusual noises, such as knocking or ticking. Check for oil leaks, coolant leaks, and exhaust leaks. Inspect the condition of the hoses, belts, and wires. If possible, perform a compression test to assess the health of the engine.

  • Transmission: Test the operation of the transmission by shifting through all the gears. Listen for any grinding or slipping. If it's an automatic transmission, check the fluid level and condition. If it's a manual transmission, check the clutch for slippage and the condition of the shift linkage.

  • Suspension: Check the condition of the shocks, struts, and springs. Look for any signs of leaks or damage. Test the handling of the car by driving it over bumps and around corners.

  • Brakes: Check the condition of the brake pads, rotors, and calipers. Look for any signs of leaks or damage. Test the operation of the brakes by performing a hard stop.

  • Documentation: Review the car's maintenance records to see how well it has been cared for. Check for any signs of neglect or abuse.

Modifications and Performance Upgrades

The Plymouth Laser, especially the turbocharged models, is a popular platform for performance modifications. However, it's important to approach modifications with caution and to ensure that they are done correctly. Here are some common modifications:

  • Boost Controller: A boost controller allows you to increase the turbocharger boost pressure, resulting in more power. However, it's crucial to monitor the air/fuel ratio and to avoid exceeding the engine's safe limits.

  • Exhaust System: An aftermarket exhaust system can improve exhaust flow, resulting in more power and a sportier sound. However, it's important to choose a system that is compatible with your engine and to ensure that it meets local noise regulations.

  • Intercooler: An upgraded intercooler can improve the cooling efficiency of the intake air, resulting in more power and reduced engine knock.

  • Fuel Injectors: Larger fuel injectors may be necessary to provide enough fuel to support increased power levels.

  • ECU Tuning: A custom ECU tune can optimize the engine's performance for specific modifications. However, it's important to choose a reputable tuner who has experience with DSM cars.

Before making any modifications, it's essential to research the potential benefits and risks. It's also important to have the modifications performed by a qualified mechanic.
