I have a FBO n18 JCW, i love the power i make around 260 on 20 psi w/ Manic Stage 2. But i kind of want to break that 300 HP mark. i guess the question i'm asking is where does the engine really start to fail with the amount of power i want to put down, my friend did mention that past 300 i would need forged internals or my engine will fail, also what are some good websites to look forged internals for an R56 thanks all, cheers!
