Review STABBER 4x Forged Connecting Rods Mitsubishi Space 1.8 133.3mm fits LANCER MIRAGE

The **STABER K2FQ59 4x Forged Connecting Rods** represent a premium upgrade for the high-performance enthusiast seeking to maximize the reliability, durability, and power potential of their **Mitsubishi 4G93** engine found in iconic models like the **Lancer, Mirage, and Space Star** with the 1.8L displacement. Engineered from **high-grade 4340 chromoly steel**, these rods are not only forged for exceptional strength and fatigue resistance but also precision-machined to exacting tolerances, ensuring flawless fitment and optimal performance. With a **133.3mm bolt pattern**, they are meticulously designed to accommodate the specific crankshaft throw of the 4G93, eliminating any risk of interference or binding while delivering superior rigidity compared to stock cast rods. The **fully counterweighted design** enhances rotational balance, reducing vibration and stress on the crankshaft and main bearings, which is particularly beneficial for high-revving applications, forced induction setups, or aggressive turbocharging scenarios. Each rod undergoes **strict quality control**, including **non-destructive testing (NDT)** and **dynamic balancing**, guaranteeing uniformity and reliability under extreme loads. Whether you're pushing the limits with a **turbocharged 4G93**, preparing for a **big-bore kit**, or simply seeking a future-proofing upgrade for longevity, these STABER rods provide the structural integrity and precision engineering required to handle the most demanding modifications. Built to withstand the rigors of forced induction and high RPM, they are an ideal choice for those who demand nothing less than the best in aftermarket performance components.

### **Pros and Cons of Buying Stabber K2FQ59 4x Forged Connecting Rods for Mitsubishi 4G93 (1.8L, 133.3mm)**

#### **Pros:**

1. **Strength and Durability** Forged connecting rods are significantly stronger than cast rods, reducing the risk of catastrophic failure under high stress. This is particularly beneficial for engines running high RPMs, forced induction, or aggressive tuning.

2. **Weight Reduction** Forged rods are often lighter than their cast counterparts, improving engine balance and reducing reciprocating mass. This can lead to better high-RPM performance and smoother operation.

3. **Longevity and Reliability** High-quality forged rods are designed to withstand extreme loads, making them ideal for heavily modified engines or those running nitrous oxide, superchargers, or turbochargers.

4. **Precision Machining** Stabber rods are known for tight tolerances and consistent quality, which helps maintain optimal engine balance and reduce wear on other components.

5. **Compatibility with High-Performance Mods** Since the 4G93 is a naturally aspirated engine, upgrading to forged rods can help it handle more aggressive camshafts, larger valves, or increased compression ratios without risking rod failure.

6. **Warranty and Support** Stabber is a reputable brand with good customer support, which can be reassuring when dealing with high-stress engine components.

#### **Cons:**

1. **Cost** Forged rods are significantly more expensive than cast rods. A full set of four (K2FQ59) will likely cost several hundred dollars, making them a substantial investment.

2. **Installation Complexity** Replacing connecting rods requires significant disassembly of the engine, including removing the crankshaft, pistons, and other components. This is best left to experienced mechanics unless you have extensive engine-building experience.

3. **Potential Overkill for Stock or Mildly Tuned Engines** If your 4G93 is running stock or with only mild modifications (e.g., mild camshaft, stock compression), the added strength of forged rods may not be necessary. Cast rods are often sufficient for these applications.

4. **Maintenance and Labor Costs** The installation process involves time-consuming work, and if you re not doing it yourself, labor costs at a shop will add to the expense.

5. **Risk of Improper Installation** If not installed correctly (e.g., incorrect rod spacing, improper bearing clearance, or misalignment), forged rods can lead to premature wear or failure. This risk is higher with aftermarket parts unless installed by a professional.

6. **Limited Aftermarket Support** While Stabber is a good brand, some aftermarket parts (e.g., pistons, crankshafts) may not be optimized specifically for these rods, requiring additional research to ensure compatibility.

### **Conclusion:**

The Stabber K2FQ59 forged connecting rods are an excellent choice for **highly modified 4G93 engines**, particularly those running forced induction, nitrous, or aggressive camshafts. They offer superior strength, durability, and reliability compared to cast rods, making them ideal for performance builds where engine longevity and stress resistance are critical.

However, for **stock or mildly tuned 4G93 engines**, the cost and complexity of installation may not justify the upgrade. In these cases, high-quality cast rods (e.g., from reputable brands like Scat, JE, or OEM) would likely suffice without the added expense.

If you re planning significant modifications (e.g., turbocharging, nitrous, or high-RPM tuning), the investment in forged rods is well worth it. For anything less aggressive, a cost-benefit analysis is recommended.

---

### **Recommendation:**

- **If your 4G93 is stock or mildly tuned (e.g., mild cam, stock compression, no forced induction):** Stick with high-quality cast rods (e.g., Scat 4340 or JE rods) to avoid unnecessary expense.

- **If you re planning forced induction, nitrous, or aggressive tuning (e.g., turbo, supercharger, high-lift cams, or increased compression):** Upgrade to the **Stabber K2FQ59 forged rods** as part of a comprehensive engine build. Pair them with a matched set of forged pistons, a reinforced crankshaft, and proper lubrication (e.g., synthetic oil with high ZDDP content) for optimal performance.

- **Always have the installation performed by an experienced engine builder** to ensure proper rod spacing, bearing clearance, and engine balance. This minimizes the risk of failure and maximizes longevity.

For the 4G93, consider whether the rods are truly necessary for your specific goals sometimes, other upgrades (e.g., a stronger crankshaft or better oil control) may be more critical depending on your build.
