For automotive enthusiasts, the thrill of transforming a naturally aspirated (NA) car into a turbocharged powerhouse is an exhilarating journey. With the right project car, you can achieve significant horsepower gains without breaking the bank. This article explores some of the best cheap project cars ideal for NA to turbo conversions, allowing you to achieve over 100 horsepower gains on a budget.
Understanding NA to Turbo Conversions
A naturally aspirated engine relies on atmospheric pressure to draw in air, while a turbocharged engine uses a turbine-driven forced induction system to compress air, resulting in greater power output. Converting from NA to turbo can significantly enhance performance, but it requires careful consideration of various factors, including engine compatibility, budget, and desired performance goals.
Factors to Consider for Turbo Conversions
- Engine Compatibility: Ensure the engine can handle the additional stress and power.
- Budget: Set a realistic budget for parts, labor, and unforeseen expenses.
- Supportive Mods: Consider necessary upgrades like intercoolers, exhaust systems, and fuel injectors.
- Skill Level: Assess your mechanical skills or the cost of hiring a professional.
