Which the NA 2.5 or the Turbo WRX, or Turbo STI. The STI is the EJ257 block which is beefy and strong as heck, but there is a semi-large issue with ringlands failing. The WRX block is the EJ255 which we have seen on the Baja turbo (I think not too much info on this motor yet). The NA EJ25 is tried and trued and been around since 2000 and is strong as heck and great and torquey but it does have high compression and is terrible for aftermarket turbo.
