FAQ
Common questions
- What are the best first mods for a VB WRX?
- A Cobb Accessport with a custom dyno tune: +15 kW and +50 Nm for $2,699, and the torque is what you feel day to day. After that, the intake, intercooler and j-pipe go on together with a retune. The intercooler is what stops the FA24 heat-soaking in traffic. Our Stage 2 car made 190.6 kW at the wheels, up from 142.2 stock. Don't fit the j-pipe without a tune. The tune is what stops the high-flow cat throwing a check engine light.
- What's the difference between the VB and VA WRX?
- The VB (2022+) uses the FA24, a 2.4L direct-injection turbo boxer. The VA (2015-2021) uses the FA20DIT, a 2.0L turbo. Different engines, different tuning approaches, different parts. This page is for VB owners.
- Can the VB WRX be tuned with EcuTek?
- No. EcuTek doesn't support the FA24DIT, so the VB WRX is Cobb only — every VB we tune runs a Cobb Accessport with a custom tune written on our in-house dyno. We use EcuTek on other Subarus; on this engine, Cobb is the platform.
- Will modifications void my warranty?
- Modifications can affect warranty on the parts they touch. RZ Stage 1 (tune only) is the lowest-risk starting point. If your car is still covered, talk to us before you book.
- Can I start with RZ Stage 1 and upgrade later?
- Yes. Start with a tune and add bolt-ons when you're ready. Your Cobb Accessport carries over, so you pay for the new hardware and the re-tune.
- How long will my car be with you?
- RZ Stage 1: Same day. RZ Stage 2: 2-3 days for hardware install plus dyno tuning. We'll confirm timing when you get in touch.
- Is the FA24 turbo reliable with more power?
- Yes. With proper tuning. The FA24DIT is a strong platform from factory. Conservative tune targets and quality supporting mods are key. We don't chase headline numbers at the expense of reliability.
