Installing Pac Racing Rods in a 2jz-gte: Step-by-step for 700+ Hp Stability

by

Installing PAC Racing Rods in a 2JZ-GTE engine is essential for achieving stability and reliability when aiming for over 700 horsepower. This guide will walk you through the process step-by-step, ensuring that your engine can handle the power you desire.

Tools and Materials Needed

  • Socket set
  • Torque wrench
  • Engine hoist
  • PAC Racing Rods
  • New rod bolts
  • Assembly lube
  • Cleaning supplies

Before starting the installation, gather all necessary tools and materials to ensure a smooth process. Having everything on hand will save you time and effort.

Preparation Steps

Begin by preparing your workspace and the engine. Follow these steps to ensure everything is ready for the installation:

  • Remove the engine from the vehicle using the engine hoist.
  • Drain all fluids from the engine.
  • Remove the oil pan, timing cover, and cylinder head.
  • Clean all surfaces thoroughly to prevent contamination.

Removing the Stock Rods

With the engine disassembled, it’s time to remove the stock rods. Follow these steps:

  • Loosen the rod bolts in a criss-cross pattern to avoid bending the rods.
  • Carefully remove the rods from the pistons.
  • Inspect the old rods for any signs of wear or damage.

Installing PAC Racing Rods

Now that the stock rods are removed, you can proceed with the installation of the PAC Racing Rods. Follow these steps closely:

  • Apply assembly lube to the new PAC Racing Rods and the pistons.
  • Align the new rods with the pistons and carefully slide them into place.
  • Insert the new rod bolts through the rods and into the pistons.

Torque Specifications

Proper torque is crucial for the stability of your engine. Follow these torque specifications:

  • Torque the rod bolts to the manufacturer’s specifications, typically around 40-50 ft-lbs.
  • Use a torque wrench to ensure accuracy.
  • Recheck torque after a few heat cycles to ensure stability.

Reassembling the Engine

Once the PAC Racing Rods are installed, it’s time to reassemble the engine. Follow these steps:

  • Reinstall the cylinder head, ensuring a proper seal with new gaskets.
  • Attach the timing cover and oil pan securely.
  • Reconnect all hoses and electrical connections.

Final Checks and Testing

Before starting your engine, perform these final checks:

  • Double-check all connections and bolts for tightness.
  • Ensure all fluids are filled to the appropriate levels.
  • Perform a pre-start inspection of the engine.

Starting the Engine

Once everything is checked, you can start the engine. Here’s how:

  • Turn the ignition key to the “on” position and wait for the fuel pump to prime.
  • Start the engine and let it idle for a few minutes.
  • Monitor for any leaks or unusual noises.

Conclusion

Installing PAC Racing Rods in your 2JZ-GTE is a significant step towards achieving the stability needed for high horsepower applications. Following this guide will help ensure a successful installation, allowing you to enjoy the performance of your engine with confidence.
