How much does the 2.0T take?
It is a turbocharged boxer with real headroom, one of the great tuning bases. Stage 1 works with standard hardware.
How does this differ from the Impreza WRX STI entry?
Our history records the model under several designations. Each group covers different units, so it is worth checking both.
Does it affect the all-wheel-drive system?
No. The work is done on the engine ECU and does not alter the operation of the drivetrain.
