Audi S3 8V 2.0TSI – Stage3 CTS turbo BB-550 hybrid 98RON+wmi
If you need a bolt-on upgraded turbocharger as a replacement for your IS38, a very good solution is the BB-550 from CTS turbo. With a little bit of help from water-methanol injection, the existing parts that the car had on stage2 and our custom engine and gearbox calibrations, it manages to produce an extra 150+whp compared to stock! Very impressive.
