I've got a 2016 N55 M2 that's currently stage 2 but later this year I'm going to make a top mount turbo setup for it.
At the moment my plan is:
I made a twin turbo setup for a 350Z in the past so I'm comfortable fabricating the turbo manifold, intake pipework, and making AN lines etc myself but one thing I'm a bit unsure of for this platform is boost control. So yeah the main point of this post:
Someone on another forum with a big turbo N55 said that they had issues with an external wastegate and went back to using the stock electronic wastegate but I'm not really sure how that's possible with a non factory turbo. There was also an old thread on here where someone mentioned the only option for external boost control was the Motiv Reflex+ control unit but that seems pretty overkill just to control a boost solenoid rather than for port injection etc which seems to be its main purpose. Is that still the only option?
Can the stock ECU with Ecutek or BM3 really not control a 3 port MAC solenoid?
Also, are there any other potential issues you guys see with my plan or other supporting mods that I need to look into? Maybe the power goal is unrealistic without meth or a LPFP upgrade?
Thanks
Chris
At the moment my plan is:
- G30-770 with 1.01AR (might also order a 0.83 AR to test)
- Turbosmart 50mm wastegate
- Dorch DS25 HPFP
- CSF intercooler
- CSF radiator
- 1 step colder spark plugs
- S63 EU5 injectors
- Aluminium intake pipework with BOV
- Vargas crank hub upgrade
- Aiming for 600-650 bhp, stock engine internals
- 99 RON UK pump gas (no meth)
