S58 vs S55 — What's the Difference?
The G80/G82 S58 engine is a significant upgrade over the F80/F82 S55. It features a closed-deck block, stronger internals, and a revised turbo setup that delivers more power and torque across the entire rev range. The result? More headroom for tuning and bigger gains at every stage.
