In Saab B2x5 case using forged piston is a must only for tuned engines with 300+ HP, but they have one downside. Standard pistons are cast in a special way to create hypereutectic phase in the alloy - it enables almost none thermal expansion. Forged pistons material due to forging is in a different phase and have significant thermal expansion. That's why casted pistons are best for normal driving. For forged you should use slightly different clearance and avoid engine load until is warms up to the operating temperature.
