Can you modify a BRZ?
Yes—there are many ways to modify a BRZ, from intake and exhaust upgrades to suspension, wheels, and cosmetic changes, with deeper performance options like forced induction. However, the scope and feasibility depend on your goals, budget, and local rules.
For context, the BRZ’s current generation (from 2022) uses a 2.4-liter FA24 engine producing about 228 horsepower, paired with a manual transmission, while earlier 2013–2020 BRZ models used a 2.0-liter FA20 engine. Parts compatibility varies by year, so always confirm fitment for your specific model before purchasing components.
What You Can Change
Owners tailor BRZs to daily driving, weekend track days, or show-ready appearances. This list highlights the most common modification categories, what they involve, and what to expect in terms of cost and impact.
- Performance power upgrades (NA and forced induction): Cold-air intake, high-flow exhaust, headers, and ECU tuning can add horsepower and improve throttle response. Results vary with configuration and require a proper tune.
- Forced induction options: Turbochargers or superchargers can unlock significant power gains but demand careful planning for cooling, fueling, and reliable installation.
- Suspension and braking upgrades: Coilovers or upgraded springs, sway bars, bushings, high-performance brake pads, rotors, fluids, and optional big-brake kits improve handling and stopping power.
- Wheels and tires: Lightweight wheels paired with sticky high-performance tires improve grip and acceleration; ensure correct offset and clearance to avoid rubbing.
- Aesthetic and interior modifications: Exterior wraps/paint, aero kits, lighting, and interior upgrades like sport seats or gauges can enhance appearance and comfort; many choices are driven by taste and use-case.
In practice, BRZ owners often blend several categories, balancing power with reliability and daily usability.
Practical considerations: warranty, legality and insurance
Before starting, weigh how modifications affect warranty coverage, emissions compliance, insurance, and resale value. Subaru’s factory warranty can be affected if a modification is linked to a problem, though some issues may still be covered if unrelated to aftermarket parts; coverage varies by region and dealer policy.
Many jurisdictions require emissions and noise compliance. In places like California, CARB-approved parts or EO numbers may be necessary for street legality; parts without approved status can be illegal for road use. Always verify local regulations and work with installers who understand emissions compliance.
Insurance considerations matter too; disclosures of modifications can raise premiums or affect coverage. If you rely on the BRZ for daily driving, check with your insurer about how specific upgrades impact your policy and claims process.
How to Approach Modifications Safely
A measured, safety-first approach helps preserve reliability while expanding capability. Start with clear goals and stage upgrades to manage risk and cost.
- Define goals and budget: decide whether you prioritize daily drivability, track capability, or show quality, and plan upgrades accordingly.
- Choose reputable parts and installers: look for BRZ/FA24 experience, read reviews, and request quotes that include professional tuning and dyno testing.
- Stage the build: begin with reliability-focused mods (e.g., intake and tune) and add handling or braking improvements as your needs evolve.
- Document and ensure compliance: retain records of parts, warranties, and any emissions approvals; confirm road-use legality in your area.
A thoughtful, staged approach helps protect reliability while achieving the desired gains.
Summary
The BRZ is widely modifiable, with options spanning intake, exhaust, ECU tuning, forced induction, suspension, braking, wheels, tires, and cosmetic updates. Prospective modifiers should balance performance with warranty, emissions compliance, and insurance considerations, and work with reputable specialists to ensure safety and reliability. Whether you’re after a more lively daily driver or a track-ready machine, planning and professional support are key to a successful, responsible build.
How do I get more horsepower out of my BRZ?
Aftermarket headers for your BRZ feature wider, smoother piping that drastically improves exhaust flow right as it leaves the engine. This is a more involved installation than a cat-back system, but the power gains are significant, especially when paired with a good intake and a proper ECU tune.
What year to avoid Subaru BRZ?
2013
Subaru BRZ years to avoid and common problems
When the BRZ was first released in 2013, drivers noticed that the valve springs were prone to failure, causing engine stalling. The NHTSA issued a recall, but not before multiple car owners had been stranded on the highway and paid thousands of dollars for engine repairs.
Can you make a BRZ fast?
Making a BRZ fast involves a few different steps, but the ultimate goal should be to balance power with handling and control. Upgrading the exhaust system and air intake can help improve horsepower, while a tune can optimize the engine's performance.
