FAQ

Common questions

What's the difference between GR and GV?
GR is the hatch, GV is the sedan, both 2008–2014. The earlier GE (sedan) and GH (hatch) ran 2007–2010. Same platform, same parts. Different body, that's it.
EJ257 ringlands. Should I be worried?
On a tired or badly-tuned motor, yes. We don't push past sensible limits on a stock bottom end, and we compression-test before we sign off on big power. If you want real numbers, start with a forged build. It's cheaper than fixing a hole.
Is a TGV delete worth it?
Yes, on a tuned car. The plastic flaps are a known cracking failure and removing them frees up flow. Pair it with a header and a re-tune. We do them every week.
How much power on a stock motor?
On a healthy EJ257 with the right supporting mods, 260–290kW at the hubs is a sensible street ceiling. Past that, plan a build.
I've got a 2015+ STI. Is that GR?
No. 2015 onwards is the VA. The VA STI kept the EJ257; the VA WRX moved to the FA20DIT. Different page.
