Achieving 400 horsepower (hp) on a budget in the UK
Mod Central
1. Buy a Used High-Potential Car
- BMW 335i/340i (E90/E92 F30): These models come with turbocharged inline-six engines that can be easily tuned to 400hp with simple bolt-on modifications like a downpipe, intercooler, and ECU tune. Used examples can be found for around £6,000-£15,000.
- Audi S4 (B8): The supercharged 3.0L V6 engine in the B8 S4 can reach 400hp with an ECU tune and some bolt-on parts. Prices start around £10,000-£15,000 for used models.
2. Turbocharge or Supercharge an Existing Car
- Mazda MX-5 (NC): Known for its handling rather than power, the NC MX-5 can be turbocharged or supercharged to reach 400hp. Kits are available and, combined with a used MX-5 (around £5,000), the total cost might be around £10,000-£15,000.
- Honda Civic Type R (EP3/FN2): These models can be turbocharged to reach 400hp. Used models can be found for £5,000-£10,000, and with a turbo kit, you’re looking at a total of around £15,000.
3. V8-Powered Cars
- Jaguar XJR (X308/X350): The supercharged V8 in these Jaguars can achieve 400hp with minimal modifications, and they can be found for as little as £5,000.
- Mercedes-Benz E55 AMG (W211): This comes with a supercharged V8 that makes close to 500hp stock. Used models can be found for around £10,000-£15,000, making it a powerful option with minimal extra investment.
4. Japanese Turbocharged Cars
- Subaru Impreza WRX STI (Blobeye/Hawkeye): With a few mods, the turbocharged EJ engine can easily reach 400hp. Used models can start around £6,000-£10,000.
- Mitsubishi Lancer Evolution (Evo VIII/IX/X): Similar to the Subaru, the 4G63 or 4B11T engines can be tuned to 400hp. Prices are higher, starting around £15,000, but the tuning potential is strong.
5. DIY Project
- BMW E36/E46 with an Engine Swap: Buy an older BMW E36 or E46 for a few thousand pounds and swap in a more powerful engine, like the 2JZ from a Toyota Supra or an LS V8. This approach requires more mechanical skill but can be done on a budget.
Estimated Costs
- Initial Purchase: £5,000-£15,000 for the car.
- Modifications/Tuning: £2,000-£7,000 depending on the car and parts.
Key Considerations
- Insurance: Higher horsepower cars and modifications can significantly increase insurance costs.
- Reliability: Ensure the car’s engine and drivetrain can handle the increased power without sacrificing reliability.
- Maintenance: Older cars or those with heavy modifications may require more frequent maintenance.
