Signs of Quality in DSM Parts

1. Authenticity & Brand Reputation

• Choose parts from reputable manufacturers or well-known DSM specialty shops.
• Genuine OEM parts ensure fitment and reliability, especially for essential components.
• High-quality aftermarket companies (STM, MAP, Volk Metal Craft, Rix Racing) offer performance and custom-fit parts tailored to DSM models.

2. Material Quality

• Look for parts made with robust materials: forged steel (internal engine), billet aluminum (brackets, fuel rails), high-density polyurethane (bushings), and powder-coated finishes for corrosion resistance.
• Stainless steel hardware is preferable for exhaust, turbo, and manifold applications to resist rust.

3. Fit and Finish

• A quality part will match OEM specifications for mounting points, thread sizes, and shape.
• Performance parts should come with precise documentation and, where applicable, install kits (gaskets, hardware).

4. Proven Performance

• Community feedback and customer testimonials often highlight truly reliable performance parts.
• Look for dyno-tested gains, racing track records, or recognized durability in high-stress environments.

5. Warranty & Support

• Reliable brands support their parts with warranties and excellent customer service, critical when investing in high-value items (engine internals, ECUs, turbos).

Customization Options for DSM Parts

DSM platforms, especially the Eclipse, Talon, and Laser, are celebrated for their customizability. Here’s how you can tailor your vehicle using modular or custom options:

1. Engine Performance

• Bolt-on upgrades: Intake manifolds, turbocharger kits, fuel system overhauls, intercoolers.
• Internal upgrades: Forged pistons, rods, ARP head studs, custom camshafts for specific power bands.
• Head gasket choices for high-boost builds.

2. Transmission & Clutch

• Stronger clutches (e.g., ACT 2600 for high horsepower).
• Shifter bushing kits and reinforced transmission mounts.

3. Suspension & Chassis

• Aftermarket coilover kits, sway bars, and custom subframes for handling.
• Weld-in chassis bracing or bolt-on tubular subframes.

4. Electronics, Tuning & Gauges

• Standalone engine management (ECMLink, AEM, Haltech) for custom tuning.
• Gauge pods, digital dashboards, and sensor upgrades.

5. Visual Modifications

• 3D-printed bezels, unique shifter assemblies, and interior trim pieces.
• Branded engine dress-up kits, custom powder-coating, and color-matched accents.

Durability Factors in DSM Parts

1. OE vs. Aftermarket

• OEM parts typically offer robust, factory-level durability and are recommended for essential systems (engine, brakes, transmission) unless aiming for horsepower beyond stock design.
• High-end aftermarket parts (e.g., billet engine mounts, steel cam gears) provide increased strength and can outlast OEM in high-stress environments.

2. Manufacturing Process

• Machined, forged, or billet components generally outlast cast parts.
• Aftermarket companies specializing in DSMs often improve on weak OEM points (e.g., shift bushings, subframe designs).

3. Environmental Resistance

• Powder-coating, anodization, and stainless steel finishes protect against corrosion, especially important for underbody, exhaust, and turbo components.

4. Serviceability

• Select parts designed for easy maintenance (modular turbo kits, quick-detach fuel lines) to promote better longevity and reduce wear during routine servicing.

Practical Tips & Best Practices for Choosing and Using DSM Parts

1. Identify Model and Year Correctly:
   1G (1990-1994) and 2G (1995-1999) DSMs have critical differences, especially in engine internals (6-bolt vs 7-bolt 4G63), wiring, and suspension mounting. Always verify fitment per your exact year/model.

2. Prioritize Quality for Key Components:

3. Engine internals, drivetrain, and suspension should always be sourced from reliable manufacturers.

4. For cosmetic or accessory items, more affordable options can often be used.

5. Consider Intended Use:

6. Daily drivers may prioritize comfort and reliability, while track builds should focus on strength, heat tolerance, and serviceability.

7. Watch for Counterfeit Parts:

8. Only purchase from established, trusted vendors. Cheap knockoffs of popular turbos, clutches, or electronics can cause catastrophic failures.

9. DIY vs. Professional Installation:

10. Certain upgrades (engine management, wiring harnesses, transmission swaps) are best installed by specialists familiar with DSM platforms.

11. Minor items (shifter bushings, gauge pods) are suitable for home installation with basic tools.

12. Futureproof Where Possible:

13. Upgrading fuel pumps or injectors? Consider buying oversized units to accommodate future mods.

14. Documentation and Support:

15. Opt for products with clear installation guides and customer support. Community forums and vendors specializing in DSMs are invaluable.

16. Stay on Top of Maintenance:

17. Even with performance parts, regular checks (timing belt, fluids, bushings) are essential to long-term reliability.

FAQ

1. What is a DSM, and which vehicles does it include?
   DSM stands for Diamond-Star Motors, a joint venture between Mitsubishi and Chrysler. DSM vehicles include the 1990–1999 Mitsubishi Eclipse, 1990–1994 Plymouth Laser, and 1990–1998 Eagle Talon.

2. How do I know if I have a 6-bolt or 7-bolt 4G63 engine?
   6-bolt engines were used in most 1990–early 1992 models, and 7-bolt engines after that. You can check the flywheel bolts or use your VIN to verify. This is key for selecting compatible performance and internal parts.

3. Should I buy OEM or aftermarket DSM parts?
   For reliability and perfect fit, OEM parts are best, especially for critical systems. Aftermarket parts are ideal for performance, tuning, and customization, as long as you choose reputable brands.

4. What are the most essential upgrades for a stock DSM?
   Popular initial upgrades include a higher-flowing fuel pump, upgraded clutch, performance intake, turbo-back exhaust, and improved intercooler for turbo models.

5. Are DSM parts easy to install at home?
   Many bolt-on upgrades (like bushings, intake kits, simple electronics) are DIY-friendly. Major mods (engine internals, transmission, ECUs) are best handled by DSM-savvy professionals.

6. Is there still good support for DSM models, given their age?
   Yes! A strong community and specialty shops offer both OEM and aftermarket support, custom fabrication, tuning, and stock or performance rebuilds.

7. Is it worth upgrading the shifter assembly or bushings?
   Upgraded shifter bushings and assemblies provide a much firmer, more precise shift feel. Kits are affordable and make a noticeable difference in drivability.

8. How do I ensure a performance part will fit my DSM?
   Always verify your trim (1G/2G, AWD/FWD, turbo/non-turbo, year, transmission type). Check product fitment charts or consult with DSM specialty vendors for compatibility.

9. What should I look for in suspension upgrades for DSMs?
   Focus on reputable coilovers, sway bars, and bushings. For track or drag use, consider chassis bracing and custom subframes from experienced fabricators.

10. Can I get support or custom parts if I have unique build goals?
    Absolutely! Many DSM vendors and garages offer custom fabrication, tuning, and sourcing. Don’t hesitate to reach out for special needs—custom support is a hallmark of the DSM community.
