The Mazda RX-8 is a sports car known for its lightweight design and unique rotary engine. However, many enthusiasts seek to boost its performance by swapping the rotary engine for a more powerful LS V8 engine. This article will assess the cost of building a 450 HP RX-8 LS swap, focusing on stroker kits and camshaft upgrades.
Understanding the LS Swap
The LS engine family, produced by General Motors, is popular among car enthusiasts for its reliability, power potential, and aftermarket support. Swapping an LS engine into an RX-8 can significantly improve performance and driving experience.
Key Components of the LS Swap
- LS Engine (5.3L or 6.0L options)
- Engine Mounts
- Transmission Adapter
- Custom Exhaust System
- Fuel System Upgrades
- Wiring Harness
- Cooling System Modifications
Stroker Kits: Enhancing Engine Displacement
Stroker kits are designed to increase the engine’s displacement, resulting in more torque and horsepower. These kits typically include a new crankshaft, pistons, and connecting rods.
Benefits of Stroker Kits
- Increased horsepower and torque
- Improved throttle response
- Better overall engine performance
Cost of Stroker Kits
The cost of a stroker kit can vary based on the components included and the brand. On average, you can expect to pay between $1,500 and $3,500 for a quality stroker kit.
Camshaft Upgrades: Optimizing Performance
Upgrading the camshaft is another way to enhance the performance of the LS engine. A performance camshaft can increase the engine’s power band and improve airflow.
Benefits of Camshaft Upgrades
- Higher RPM power delivery
- Enhanced engine sound
- Improved fuel efficiency (with proper tuning)
Cost of Camshaft Upgrades
Performance camshafts can range in price from $300 to $1,200, depending on the brand and specifications. Additionally, installation costs should be considered, which can add another $500 to $1,000.
Additional Costs to Consider
Beyond the stroker kits and camshaft upgrades, several other costs are associated with the LS swap project.
- Labor Costs: If you’re not doing the swap yourself, labor can add $2,000 to $5,000.
- Performance Tuning: After the swap, tuning is essential and can cost between $500 and $1,500.
- Miscellaneous Parts: Expect to budget an additional $500 to $1,000 for miscellaneous parts like gaskets, fluids, and hardware.
Total Cost Estimate
When calculating the total cost of building a 450 HP RX-8 LS swap with stroker kits and camshaft upgrades, you can expect the following breakdown:
- LS Engine: $2,500 – $5,000
- Stroker Kit: $1,500 – $3,500
- Camshaft Upgrade: $800 – $2,200
- Labor Costs: $2,000 – $5,000
- Performance Tuning: $500 – $1,500
- Miscellaneous Parts: $500 – $1,000
Overall, the total estimated cost for this project can range from approximately $8,300 to $19,200 depending on the choices made throughout the build process.
Conclusion
Building a 450 HP RX-8 LS swap with stroker kits and camshaft upgrades is an exciting project for automotive enthusiasts. By carefully assessing the costs and planning accordingly, you can create a powerful and reliable vehicle that stands out on the road.
