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.

Will modifications void my warranty?

Modifications can affect warranty coverage on related components. RZ Stage 1 (tune only) is the lowest-risk starting point. Happy to discuss your specific situation and what makes sense for your car.

Can I start with RZ Stage 1 and upgrade later?

Absolutely. That's how we designed the packages. Start with a tune, add bolt-ons when you're ready. Your Cobb Accessport carries over. You just pay for the re-tune with new hardware.

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.
