All under one roof
Beyond the packages
Same building, same techs. Servicing, custom upgrades, and dyno work outside the off-the-shelf packages.
Servicing & maintenance
VA WRX runs the FA20DIT, VA STI runs the EJ257. Two engines, two service approaches. We do both, without the dealer markup.
- Logbook servicing
- Direct injection cleaning (FA20DIT)
- AVCS & cooling (EJ257)
- Pre-track inspections
Performance upgrades
Two engines, two upgrade paths. The FA20DIT WRX likes intake and intercooling first. The EJ257 STI rewards a TGV delete and a header. We fit what makes sense for your car.
- Intake, intercooler & DP
- TGV delete (STI)
- Turbo upgrades
- Coilovers & brakes
Custom dyno tuning
Custom dyno tuning w/ EcuTek on our in-house Dynapack. Each map is built from scratch for your car. No flash files, no shortcuts.

- E85 & flex fuel
- Boost & launch control

FAQ
Common questions
- Is the VA WRX the same as the VA STI?
- Same chassis, different engines. VA WRX runs the FA20DIT, 2.0L direct-injection turbo. VA STI runs the EJ257, port-injected, 2.5L, and the last EJ STI Subaru ever built. We tune both, but they're different jobs.
- How much power can a VA WRX safely make?
- FA20DIT responds well to a tune and basic bolt-ons. 220–250kW at the hubs is a sensible street target. Past that the factory turbo runs out and you're into a turbo upgrade and fuelling work.
- Is the VA STI worth modding given its age?
- Yes. It's the last EJ STI ever made and aftermarket support is still strong. We treat them as keepers: conservative targets, quality parts, no shortcuts on the supporting mods.
- Will modifications void my factory warranty?
- Most VAs are out of factory warranty by now, but mods can still affect dealer goodwill. A tune is the lowest-risk starting point. Happy to walk through your specific car.
- I've got a 2022+ WRX. Is that VA?
- No. 2022 onwards is the VB (FA24DIT). Different engine, different page.
