M2 N55 Pure Stage 2 Advice Needed
Hey all, N55 M2 looking for turbo upgrade advice:
Just ordered a Pure Stage 2 Turbo with the upgraded DV and inlet pipe, Spool Stage 3 LPFP, 3.5 bar TMAP sensor, ordered some extra NGK97506 plugs and some new Delphi 12138616153 coils. I'm already FBO with a Dorch Stage 2 HPFP and a BM3 Flex Fuel kit. Is there anything I need? Am I missing something or do I just need to install and tune now? Is a crank hub solution necessary? Goal is to be able to run ethanol blends and make north of 500whp. Thanks in advance! |

Other than that you should be fine, I personally don't think a crank hub fix is required because people were running 550 whp+ on the N55 for years before the crank hub issue was a huge talking point and there hasn't been a huge issue as a result. The n55 has alot less inertial mass driven off of the crank hub so you should be ok at this power level.

For sure! I was free revving it against the limiter on E80 the other day and got super knock + injector shutdown on cylinder 2, so hopefully she goes more instead of blows lol. I figured if this thing is gonna die I want it to be in a blaze of boost, not some punk E80 maxed out stock turbo BS lol

That's a good philosophy. So if you wanted you could get the upgraded hubs, but it's not really needed.

Think I'll need a LPFP controller? I've heard that higher power LPFP's can fry the EKP. If so, any suggestions? |

Looks good to me, but I recommend talking to your tuner about your power goals, and they'll let you know if they can do it with your current mod or if you need anything else.

I did send in an email to your sites support to modify my order to a stage 2 LPFP instead of the stage 3 LPFP. I just don't think I'll need the stage 3 tbh lol. Hopefully they're able to change it since the order hasn't been shipped yet. |

You're gonna need to talk to your hpfp manufacturer and tuner to check.
