If you're the proud owner of a 1999 Mitsubishi Eclipse GSX, you know this car isn't just any ordinary vehicle. It's a piece of automotive history, sporting a sporty turbocharged design, all-wheel-drive prowess, and the kind of street cred that only a true '90s sports coupe can muster. However, like any car that has seen almost three decades, your Eclipse might need some TLC to keep it running smoothly. Here are seven secrets to revive your beloved '99 Eclipse GSX and ensure it not only runs well but also turns heads in its classic charm.

Understand Your Engine

The heart of the Eclipse GSX lies in its 4G63 engine, a gem that has powered many legendary Mitsubishi models. Here's what you need to know:

The Engine: The 4G63T is a 2.0-liter turbocharged inline-4, known for its robustness and potential for modification.

• Maintenance: Regular oil changes are crucial. High-quality synthetic oil and high-performance filters help keep the turbocharger and pistons in top shape.
• Inspection: Regularly check the turbocharger for wear or damage. Look for oil leaks around the turbo area, which might indicate seal issues.
• Upgrade: If you're looking for better performance, consider upgrading the intercooler, fuel injectors, and possibly even turbo itself.

Inspect and Upgrade the Suspension

A well-maintained suspension is key for handling and ride comfort:

Check Points:

• Inspect shock absorbers and struts for leaks or wear.
• Look for signs of rust or corrosion on the springs and control arms.
• Assess the bushings for signs of wear or cracking.

Upgrades:

• Consider lowering springs or coilovers for a sportier stance and better handling.
• Performance sway bars can significantly reduce body roll, enhancing the car's cornering ability.

• Inspect pads, rotors, brake lines, and the master cylinder for wear.
• Ensure no leaks are present in the system.

Upgrades:

• Consider high-performance brake pads and slotted or drilled rotors.
• Stainless steel braided brake lines can enhance braking response.

Polish and Paint Protection

The Eclipse GSX's design demands to be seen in its best form:

Maintenance:

• Regular washing, waxing, and polishing are vital to protect the paint.
• Address any signs of rust or chips promptly to prevent further damage.

Upgrades:
