F30 power after BM3 Stage 2
Hey so I've currently got a '12 N20 328i with the following:
Bm3 stage 2 ER intercooler ER chargepipe Injen CAI VRSF downpipe AWE touring exhaust I'm curious if I'm missing any options for more power without worrying about the internals? From what I've read it appears that they're pretty weak and maxed at about ~300 hp... which means no stage 2 turbo is worth it? Its been a blast learning about this platform and I'd like to keep the ball rolling. Thanks |

You can upgrade the turbo for a bit more top end if you really want it and it will be perfectly safe on stock internals as long as it's tuned for correctly (i.e. keep boost below 22 psi). But yes, stage 2 (what you have) is considered FBO and pretty much as far as you can go without upgrading anything else to support.

These engines are more torque limited than hp limited. Get an MHI turbo and a custom tune that limits lowend and emphasizes topend. This will put less stress on the engine/drivetrain etc. The people that are breaking things are the ones pushing the stock turbo way too hard (very high lowend torque numbers).
