Cost Breakdown: How Much to Achieve 500 Hp with a 2jz Swap 240sx Using Aftermarket Internals

The Nissan 240SX is a beloved platform for car enthusiasts, especially when it comes to engine swaps. One of the most popular swaps is the Toyota 2JZ engine, known for its reliability and performance potential. In this article, we will break down the costs associated with achieving 500 horsepower with a 2JZ swap in a 240SX, focusing on the use of aftermarket internals.

Understanding the 2JZ Engine

The 2JZ engine, particularly the 2JZ-GTE variant, is renowned for its robust design and ability to handle high horsepower levels. This inline-six engine features a cast iron block and aluminum DOHC cylinder head, making it a solid choice for performance builds.

Initial Costs of the Swap

Before diving into the costs of aftermarket internals, it’s essential to consider the initial expenses involved in the engine swap itself. Here’s a breakdown of the primary costs:

  • 2JZ-GTE Engine: $3,000 – $5,000
  • Engine Mounts: $200 – $500
  • Transmission (R154 or similar): $1,000 – $2,000
  • Wiring Harness: $300 – $600
  • ECU (Standalone or modified): $500 – $1,500
  • Labor (if not DIY): $1,000 – $3,000

In total, the initial costs for the swap can range from approximately $6,300 to $12,600, depending on the quality of parts and labor.

Aftermarket Internals for 500 HP

To achieve 500 horsepower reliably, upgrading the internals of the 2JZ engine is crucial. Below is a list of essential aftermarket components and their associated costs:

  • Forged Pistons: $600 – $1,200
  • Forged Connecting Rods: $600 – $1,200
  • Upgraded Crankshaft: $800 – $1,500
  • Upgraded Cylinder Head (porting and valve job): $1,000 – $2,000
  • Performance Camshafts: $500 – $1,000
  • Head Gasket (high-performance): $150 – $300
  • ARP Head Studs: $200 – $400

These upgrades can add anywhere from $3,100 to $7,100 to the total cost of the build, ensuring that the engine can handle the desired power level.

Supporting Modifications

In addition to the engine internals, several supporting modifications are necessary to achieve and maintain 500 horsepower. These include:

  • Upgraded Turbocharger: $1,500 – $3,000
  • Intercooler: $300 – $800
  • Fuel System Upgrades (injectors, pump): $500 – $1,200
  • Exhaust System: $500 – $1,000
  • Upgraded Cooling System: $300 – $600

The cost for these supporting modifications can range from $3,100 to $6,700, depending on the quality and brand of parts chosen.

Total Cost Breakdown

Now that we have an understanding of the costs involved, let’s summarize the total expenses for achieving 500 horsepower with a 2JZ swap in a 240SX:

  • Initial Swap Costs: $6,300 – $12,600
  • Aftermarket Internals: $3,100 – $7,100
  • Supporting Modifications: $3,100 – $6,700

The total cost can range from approximately $12,500 to $26,400, depending on choices made throughout the build process.

Conclusion

Achieving 500 horsepower with a 2JZ swap in a Nissan 240SX is an exciting project that requires careful planning and budgeting. By understanding the costs associated with both the initial swap and the necessary aftermarket upgrades, enthusiasts can make informed decisions to create a powerful and reliable vehicle. Remember to factor in potential labor costs and the quality of parts when estimating your total budget.
