Trying to increase my hp on a cummins n14 celect plus 400 hp. CPL 2591 serial number 12041843. It’s not a red top. Just had the engine inframed. Overhaul kit uses same part number as the higher horsepower engines. From what I can tell the only difference between my engine and a 525 hp is the heads, injectors, and turbo. I was wondering if anyone can tell me what I would be able to crank this thing up to without hurting the engine. Aiming for at least 435 hp
