What turbo parts fit my Subaru WRX STI 2015-2021 (VA chassis)?

No. Standard VA turbo hardware is carried-over EJ257 equipment, while the S209 alone gets a larger HKS-manufactured STI turbocharger, with the turbine 6% larger and the compressor 8% larger. Do not assume S209 and standard-car turbo parts interchange.
