Hi there,
I'd say the upgrade potential depends on the exact engine that's now in the car. If from 15 onwards will be a Volvo VEA engine. These have a number in format B4204Txx. The B4204T11 would possibly go to 300 with a map - bigger turbo, lower compression and bigger crank shaft. If its one of the lesser powered versions like B4204T37 these would go to 210 maybe. A bigger turbo maybe a problem on these with 11.3:1 compression - it's possible the T11 type has a lower 10.3:1 (IIRC) to allow more boost without detonation. Also these engines have a smaller crank.
