Forced Induction
⚡ Double Your Power
Transform your MX-5 from fun to ferocious with turbocharging or supercharging. From bolt-on kits to custom builds, explore the path to serious power gains.
Expert Level Modification
Forced induction is complex and requires significant supporting modifications. Improper installation can damage your engine. Consider professional installation and tuning for best results.
Turbo vs Supercharger
Turbocharger
Advantages
- • Higher efficiency (uses exhaust energy)
- • Better fuel economy when not in boost
- • More power potential at high RPM
- • Cooler air charge (with intercooler)
- • More tuning flexibility
Disadvantages
- • Turbo lag below boost threshold
- • More complex installation
- • Heat management challenges
- • More supporting modifications needed
- • Potential oil supply issues
Best For:
Maximum power builds, track cars, those who don't mind complexity
Supercharger
Advantages
- • Instant throttle response (no lag)
- • Simpler installation and plumbing
- • More reliable (fewer moving parts)
- • Better low-end torque
- • Easier to tune and maintain
Disadvantages
- • Uses engine power to make power
- • Higher intake air temperatures
- • More expensive for equivalent power
- • Limited high RPM potential
- • Constant parasitic load
Best For:
Street cars, autocross, those who want reliability and simplicity

Required Supporting Modifications
Critical Components
These modifications are typically REQUIRED for safe forced induction operation. Skipping any can result in engine damage.
Engine Internals
Engine Management
Standalone ECU or piggyback system for proper tuning
Fuel System Upgrade
Larger injectors, fuel pump, possibly fuel rail
Intercooler (Turbo)
Cool charged air for power and reliability
Engine Rebuild
Lower compression pistons, forged internals for high boost
Supporting Systems
Clutch Upgrade
Handle increased torque output
Radiator/Cooling
Manage additional heat from forced induction
Oil Cooler
Maintain proper oil temperatures under boost
Torsen LSD
Handle power delivery and traction
Power & Cost Breakdown
Conservative Build ($5,000-8,000)
Target Power
Safe, reliable daily driver power
Key Components
- • Basic turbo kit or supercharger
- • ECU tune or piggyback
- • Clutch upgrade
- • Basic supporting mods
Reliability
Stock engine can handle this power level with proper tune
Performance Build ($8,000-15,000)
Target Power
Serious performance, weekend warrior
Key Components
- • Quality turbo kit with intercooler
- • Standalone ECU

May need engine refresh sooner, proper maintenance critical
Race Build ($15,000-30,000+)
Target Power
Track/race only, maximum performance
Key Components
- • Engine rebuild with forged internals
- • Large turbo with custom setup
- • Race fuel/E85 capability
- • Full safety equipment
Reliability
Frequent maintenance, not suitable for street use
Installation & Tuning
Professional Recommendations
- •Find experienced tuner - Miata-specific knowledge crucial
- •Dyno tuning essential - Street tuning not safe for FI
- •Budget for professional install - $1,500-3,000 labor
- •Plan for iterations - First tune rarely perfect
- •Data logging setup - Monitor AFR, knock, temps
Common Mistakes to Avoid
- ⚠Skipping fuel system - Will lean out and damage engine
- ⚠Cheap ECU tune - Generic maps don't work for FI
- ⚠Ignoring heat management - Leads to detonation
- ⚠Too much boost too soon - Start conservative
- ⚠Inadequate oil supply - Turbos need clean oil flow
