### **Pros and Cons of Buying Maxpeedingrods VRY87E Steel 4340 EN24 Connecting Rods with ARP Bolts for Nissan FJ20 Skyline (DR30) / Silvia S12**
#### **Pros:**1. **High-Strength Material (4340 Steel)** The VRY87E rods are forged from **4340 steel**, a chromium-molybdenum alloy known for its excellent strength-to-weight ratio, fatigue resistance, and durability under high stress. This makes them far superior to cast-iron or lower-grade steel rods in stock engines.
2. **EN24 Grade (High-Quality Forging)** EN24 is a premium forging grade, ensuring consistent material properties and minimal defects. This reduces the risk of catastrophic failure, even under extreme power levels.
3. **ARP Bolts Included** The kit comes with **ARP 10000 psi bolts**, which are significantly stronger than stock bolts. ARP bolts are heat-treated and designed for high-performance applications, reducing the risk of bolt stretch or failure under heavy loads.
4. **Balanced Weight & Strength** The rods are **lightweight yet robust**, improving engine balance while maintaining structural integrity. This helps reduce reciprocating mass, which can improve engine efficiency and longevity.
5. **Compatibility with Stock Crankshaft** The VRY87E rods are designed to fit the **stock FJ20 crankshaft** without requiring modifications, making installation straightforward for most builds.
6. **Aftermarket Support & Reputation** Maxpeedingrods is a well-regarded brand in the tuning community, with a history of producing reliable components for high-performance applications. Their rods are often recommended for **turbocharged, supercharged, or naturally aspirated high-RPM builds**.
7. **Potential for Increased Power & Reliability** Upgrading to these rods can allow for **higher compression ratios, more aggressive camshafts, or forced induction** without compromising engine strength. This is particularly useful for **DR30 (GT-R) or S12 (Silvia) builds** pushing beyond stock limits.
8. **Warranty & Customer Service** Maxpeedingrods offers a **warranty** on their rods, and their customer service is generally responsive, which is important for aftermarket parts.

#### **Cons:**1. **Cost** These rods are **not cheap**, typically ranging in the **$800 $1,200 range** depending on market fluctuations. This is a significant investment compared to stock or lower-tier aftermarket rods.
2. **Installation Complexity** While the rods fit stock cranks, installation still requires **careful assembly**, including proper **bearing clearance checks, rod bearing selection, and torque specifications**. Improper installation can lead to premature wear or failure.
3. **Not a "Drop-In" Replacement** Unlike some aftermarket rods, these are **not a simple bolt-on upgrade**. You may need to **replace bearings, adjust oil squirt holes, or modify the oil passages** to ensure proper lubrication and cooling.
4. **Potential for Overkill on Stock Engines** If your engine is **stock or lightly modified (e.g., mild camshaft, no forced induction)**, these rods may be **more than necessary**. For such builds, a **budget-friendly aftermarket rod kit** (e.g., JE, Scat, or even some stock replacements) might suffice.
5. **Requires Supporting Modifications** To fully utilize these rods, you may need to **upgrade other components** such as:- **Crankshaft** (if running extreme power)
- **Pistons** (forged or high-compression)
- **Oil pump & filter** (to ensure proper lubrication)
- **Exhaust manifolds & headers** (for better scavenging)
- **Fuel & ignition upgrades** (if increasing power)
6. **Risk of Improper Use** If the engine is **not properly supported** (e.g., weak internals, poor oil flow, or excessive heat), even high-quality rods can fail. This requires **knowledge of engine tuning and maintenance**.
7. **Limited Stock Availability** Like many high-end aftermarket parts, these rods may **not always be in stock**, requiring patience or ordering from a specialty supplier.

### **Ending Conclusion:**The **Maxpeedingrods VRY87E 4340 EN24 rods with ARP bolts** are one of the **best aftermarket rod options** for the **Nissan FJ20 Skyline (DR30) and Silvia S12**, especially for **high-performance builds** (turbocharged, supercharged, or high-RPM naturally aspirated). They offer **superior strength, reliability, and compatibility** with stock cranks, making them ideal for **serious tuners** pushing beyond stock limits.
However, they are **not a necessity** for **stock or mildly modified engines**. The cost and installation demands make them **overkill** for basic builds. If you're planning a **serious power increase (500 hp or aggressive forced induction)**, these rods are a **strong recommendation**. For **lower-power builds**, a **more budget-friendly rod kit** may be sufficient.
### **Recommendation:** - **Buy if:**- You are running **forced induction (turbo/supercharger)** or **high-RPM NA builds** (e.g., 8,000 RPM).
- You want **maximum reliability** for **high-power applications** (e.g., 600 hp).
- You are **rebuilding your engine** and want **premium internals** for longevity.
- You are **not on a tight budget** and want the **best aftermarket rods** available.
- **Avoid if:**- Your engine is **stock or lightly modified** (e.g., mild cam, no forced induction).
- You are **not prepared for the installation complexity** or supporting modifications.
- You want a **budget-friendly upgrade** (consider JE, Scat, or stock replacements instead).
- You are **not committed to proper engine maintenance** (these rods require good oil flow and cooling).
**Final Verdict:** For **high-performance FJ20 builds**, these rods are **one of the best choices** if the budget and build goals justify them. For **stock or mild builds**, they are **unnecessary**. Always ensure the rest of your engine is **properly supported** to maximize their benefits.
