Review MAXPEEDINGRODS Connecting Rods Arp Mitsubishi Space 1.8 133.3mm fits LANCER MIRAGE 2000

The **Maxpeedingrods PKAJN4 ARP 2000 Connecting Rods** are a high-performance, precision-engineered upgrade designed specifically for the Mitsubishi 4G93 engine found in iconic models like the Lancer, Mirage, and Space Star particularly those with a 1.8L displacement and a 133.3mm stroke. These rods are meticulously crafted from **ARP 2000-grade steel**, a material renowned for its exceptional strength-to-weight ratio, ensuring superior durability under extreme stress while maintaining reliability. Unlike stock rods, which are often optimized for stock power levels, the PKAJN4 rods feature a **forged construction with optimized wall thickness and heat treatment**, allowing them to withstand the increased loads generated by forced induction, high-RPM tuning, or aggressive engine modifications without compromising structural integrity. The design incorporates **precision-machined big-end bearings** and **optimized rod length and offset**, which help reduce reciprocating mass and improve engine balance, leading to smoother operation and enhanced efficiency critical benefits for engines pushing beyond their stock limits. These rods are **fully compatible** with the 4G93 s stock crankshaft and are engineered to handle the demands of turbocharged, nitrous-assisted, or high-compression setups, making them an ideal choice for enthusiasts looking to extract maximum power while maintaining longevity. Whether you're building a daily driver with a mild turbo kit or a high-revving, high-torque monster, the Maxpeedingrods PKAJN4 rods provide the robustness and precision needed to handle the most aggressive modifications without sacrificing performance or reliability. Built to ARP s exacting standards, these rods are a testament to engineering excellence, offering a seamless upgrade path for those seeking to push their 4G93 engine to its absolute limits.

### **Pros and Cons of Buying Maxpeedingrods PKAJN4 Connecting Rods (ARP 2000) for a Mitsubishi 4G93 (Lancer, Mirage, Space Star, 1.8L, 133.3mm OEM rod length)**

1. **Higher Strength and Durability** ARP 2000 rods are forged from high-strength 4340 steel, which is significantly stronger than the stock OEM rods. This makes them ideal for forced induction (turbo/supercharging), high RPM applications, or aggressive engine modifications.

2. **Increased Reliability Under Stress** The 4G93 engine is known for rod bolt failures under heavy loads, especially when modified. ARP rods reduce the risk of catastrophic failure by maintaining structural integrity under extreme stress.

3. **Better Compatibility with Aftermarket Parts** If you plan to add a turbo, supercharger, or high-performance camshaft, these rods will handle the increased torque and RPM better than stock rods.

4. **Long-Term Engine Protection** Since the 4G93 is prone to rod bolt stretch and fatigue, upgrading to ARP rods can extend the lifespan of your engine, especially if you push it beyond stock limits.

5. **Warranty and Support** ARP is a well-known brand with a reputation for quality, and Maxpeedingrods provides proper installation guidance and support.

6. **Maintains Stock Rod Length (133.3mm)** Unlike some aftermarket rods that require crankshaft modification, these rods keep the same length as OEM, so no additional work is needed on the crank or main bearings.

7. **Improved Performance Potential** If you're running a high-flow intake, aggressive cam, or forced induction, these rods will help prevent failure and allow you to extract more power safely.

---

1. **Cost** ARP rods are significantly more expensive than OEM or even some budget aftermarket options. The price point may be prohibitive for casual enthusiasts or those on a tight budget.

2. **Installation Complexity** While not extremely difficult, installing ARP rods requires proper torque specifications, gasket surface prep, and alignment. Improper installation can lead to issues, so it s best done by a professional.

3. **Not Necessary for Stock or Mild Mods** If you're only running a stock engine or minor mods (e.g., mild cam, stock turbo), the stock rods may suffice. ARP rods are best for aggressive builds.

4. **Weight** ARP rods are heavier than stock rods, which could slightly reduce high-RPM responsiveness, though the difference is minimal in most applications.

5. **Potential for Overkill** If you're not planning significant power gains (e.g., 200 HP with forced induction), the extra cost may not be justified.

6. **Requires Rod Bolt Upgrade** Since ARP rods are designed for high-stress applications, you should also upgrade to ARP rod bolts (or at least high-quality aftermarket bolts) to match their strength.

7. **Limited Availability of Stock Parts** If you ever need to return to stock rods (e.g., for warranty or resale), finding exact OEM replacements may be difficult, though this is rare.

### **Recommendation**

The **Maxpeedingrods PKAJN4 ARP 2000 connecting rods** are an excellent choice if you're modifying your **Mitsubishi 4G93** for **forced induction, high RPM, or aggressive power gains**. They provide **superior strength, reliability, and longevity** compared to stock rods, making them a smart investment for serious builders.

However, if you're running a **stock or mildly modified engine** (e.g., stock turbo, mild cam, no boost), the **stock rods may be sufficient**, and the cost of ARP rods may not be justified. In such cases, a **budget rod upgrade (e.g., JE, Scat, or even high-quality OEM replacements)** could be a more practical choice.

- You're running **forced induction (turbo/supercharger) with significant boost**.

- You're **aggressively modifying the engine** (big cams, high RPM, nitrous, etc.).

- You want **maximum reliability and longevity** under extreme stress.

- You're building a **high-performance or competition engine**.

- You're keeping the engine **stock or mildly modified**.

- You're on a **tight budget** and don t need extreme strength.

- You plan to **stick with stock or minimal power gains** (e.g., 150-180 HP naturally aspirated).

For most **4G93 builds pushing 200 HP with forced induction**, ARP rods are **highly recommended**. For everything else, consider whether the cost is worth the benefit. Always pair them with **proper rod bolts, gaskets, and installation** to ensure maximum effectiveness.
