The Mitsubishi Starion: A Comprehensive Guide

Introduction

The Mitsubishi Starion, a rear-wheel-drive, turbocharged sports coupe, holds a special place in automotive history. Produced from 1982 to 1989 (1989 model year being very limited and sometimes titled as 1990), it emerged during a period of rapid technological advancement and fierce competition in the performance car market. The Starion was Mitsubishi's attempt to compete with the likes of the Toyota Supra, Nissan 300ZX, and Mazda RX-7, offering a blend of performance, style, and innovation. It was initially marketed as the Dodge/Chrysler Conquest in North America, adding to its mystique and collectability. The Starion is considered a front-engine, rear-wheel-drive, grand tourer with sporting ambitions.

Generations

First Generation (1982-1985)

The initial models (A183A chassis code) are easily identifiable by their narrower body and more angular styling, often referred to as "flatty" or "narrow body" Starions. These models were available with a 2.0-liter turbocharged inline-four engine. Power varied depending on the market.

  • Key Changes: Introduced the core Starion platform. Early models featured MCA-Jet fuel injection. Available in Japan as the Celica XX fighter.
  • Engine: 2.0L G63B turbocharged inline-four (varies depending on market and year)

Second Generation (1986-1989)

The second generation (A187A chassis code) featured a wider body, more aggressive styling, and significant mechanical upgrades. This is the most desirable generation for many enthusiasts.

  • Key Changes:
    • Wider fenders and body for improved handling and more aggressive stance.
    • Upgraded suspension components, particularly in the "SHP" (Sport Handling Package) versions.
    • Larger brakes.
    • Improved interior design.
    • Introduction of the 2.6-liter turbocharged engine.
    • Available in Japan as the Starion GSR-VR.
  • Engine: 2.6L G54B turbocharged inline-four. The 2.0L engine was phased out in most markets.
  • Transmissions: 5-speed manual and 4-speed automatic.

Reliability & Common Issues

While the Starion offers a rewarding driving experience, potential buyers should be aware of several common issues:

Rust

Rust is the Starion's biggest enemy. Check thoroughly for rust, especially in these areas:

  • Lower rocker panels
  • Rear wheel arches
  • Floor pans
  • Hatch area
  • Strut towers
  • Around the windshield and rear window seals

Even seemingly minor surface rust can indicate more significant corrosion underneath. Pre-purchase inspections are highly recommended.

Engine Issues (2.6L G54B)

The 2.6-liter G54B engine, while robust, has some inherent weaknesses:

  • Balance Shafts: The balance shafts are driven by a timing chain and can cause issues if the chain tensioner fails or the chain stretches. Many owners opt to remove the balance shafts (the "balance shaft delete") to improve engine reliability, but this increases engine vibration.
  • Cylinder Head: Prone to cracking, especially from overheating. Check for coolant leaks or signs of head gasket failure.
  • Turbocharger: The original turbochargers can fail due to age and wear. Rebuilds or replacements are often necessary. Check for excessive shaft play and oil leaks.
  • Oil Starvation: Ensure the oil pump is functioning correctly. Pay attention to oil pressure readings.
  • Fuel Injection: The original fuel injection system (particularly the earlier iterations) can be finicky. Consider upgrading to a more modern system for improved reliability and performance.

Electrical Issues

As with many cars of this era, the Starion can suffer from electrical problems:

  • Wiring Harness: The wiring harness can become brittle and cracked over time, leading to shorts and malfunctions.
  • Sensors: Sensors (such as the mass airflow sensor and oxygen sensor) can fail, causing poor engine performance.
  • Grounding: Poor grounding can cause various electrical problems. Ensure all grounding points are clean and secure.

Suspension and Brakes

  • Bushings: The suspension bushings can deteriorate over time, leading to sloppy handling.
  • Brakes: The brakes can be prone to fading, especially under hard use. Upgrading to aftermarket brake pads and rotors is a common modification. Check the condition of the brake lines.

Interior

  • Cracked Dash: A common problem. Aftermarket dash covers can help improve the appearance.
  • Seat Wear: The original seats can wear out, especially in high-wear areas.
  • Missing or Broken Trim: Sourcing replacement interior trim pieces can be challenging.

Driving Experience

The Mitsubishi Starion, when properly maintained, offers a unique and engaging driving experience. It's a raw and visceral sports coupe that rewards skilled drivers.

Pros:

  • Turbocharged Power: The turbocharged engine provides strong acceleration and a distinctive turbocharger whine.
  • Rear-Wheel Drive: Offers excellent handling and the potential for drifting (when done responsibly and on a track).
  • Distinctive Styling: The Starion's wedge-shaped design and aggressive lines make it a head-turner.
  • Potential for Tuning: The engine is relatively easy to modify for increased power.
  • Collectability: Increasing in value, especially well-preserved examples.

Cons:

  • Age: Requires regular maintenance and repairs due to its age.
  • Reliability Issues: As mentioned above, certain issues are common.
  • Parts Availability: Some parts can be difficult and expensive to find.
  • Turbo Lag: Noticeable turbo lag is present, which can take some getting used to.
  • Ride Quality: Can be harsh, especially on rough roads.

Buying Advice

If you're considering purchasing a Mitsubishi Starion, here's some advice:

Years to Look For:

  • 1987-1989 (Widebody): These models offer the most refined styling, improved handling, and generally benefit from minor improvements over the earlier models. The SHP (Sport Handling Package) versions are highly desirable.
  • 1986 (Early Widebody): These are still good options, but may not have all the refinements of the later models.

Years to Avoid (or be Extra Cautious With):

  • 1982-1985 (Narrow Body): While charming in their own right, these models are less desirable due to their narrower body and less powerful engines. Parts availability can also be more challenging. Be prepared for extra maintenance.
  • Extremely Modified Examples: Unless the modifications were done professionally and with high-quality components, avoid heavily modified Starions. Poorly executed modifications can introduce a host of new problems.

Key Considerations:

  • Rust: Prioritize finding a Starion with minimal rust. A clean body is the best starting point.
  • Maintenance History: Look for a well-documented maintenance history. This indicates that the car has been cared for.
  • Pre-Purchase Inspection: Have a qualified mechanic inspect the car before you buy it. This can help you identify potential problems.
  • Budget: Factor in the cost of repairs and maintenance when setting your budget. Owning a classic car requires a financial commitment.
  • Community: Join online Starion forums and communities. These can be invaluable resources for information, parts, and support.

The Mitsubishi Starion is a rewarding but demanding classic car. With careful research, patience, and a willingness to invest in its upkeep, you can enjoy a unique and engaging driving experience that few other cars can offer.
