Yep, bottom end and tranny all good to around 500whp and 600wtq. Mostly forged internals, unlike the updated N55 (single turbo engine after 2010), which needs pistons and crankshaft for silly power, but can still hold 500wtq on stock. The brakes are also good enough for that kind of power, which is great, cos that's an expensive upgrade when its needed. Well built, these panzers.
