So who's the cat from Tennessee that has a white 128i in at BPC for the MILVS installation today?
We have a shared malady with our VAICO DISA valves...but I started another thread on that so as not to clutter up the MILVS thread: https://www.1addicts.com/forums/show...1#post23478021 |

I suppose we should vote on exactly what "FBO" means for the N51/2, now that guys are getting more and more adventurous here lol. Should a BBTB be part of it?
At a minimum I'd say.. Modified Intake (Typically either Eurobox w/ Silicone Inlet, or aFe Sealed, or deleted charcoal filter w/ silicone inlet) 3 Stage or N54 Intake Manifold MILVS Headers Secondary Cat Delete (Race Pipes) Cat-Back Exhaust

BBTB should be added. Either N54 or Riot 80mm.
Especially if headers are on the list. And Tune. It is really an integral part to tie all the FBOs together. |

It would just be the Intake, header and exhaust system being modified in some way. |

I feel a little bit like a BBTB mod makes more sense with the N54 manifold rather than 3 stage because dynos I have seen show a few added hp way up at the top of the rpm range like 6k+ where the 3 stage manifold seems to be outperformed by the N54 manifold.

I'm also with you Task in that MILVS, which are most closely related to cams, aren't typically considered a bolt-on. That said, I think they should be included just because they make as much a difference as most other 'bolt-on's' if not more - and typically anyone here that is serious about adding power opts to install them. Marty, why do you say BBTB should be included "especially if" headers are included? I'm under the impression that headers will provide a great deal more power than the BBTB. Am I wrong? I don't think one has been dyno tested here yet, but I feel like the BBTB is a 'just cause, why not?' sort of mod that is done when there is nothing else left to do. I think I remember Biginboca testing his via Draggy but can't remember what his results were (also can't remember if he tested it alone or if it was in conjunction with other mods). Quote:

Just that the 'ease of bolting on' of BBTB compared to headers. Not that they make more power. Headers install is a PITA.
FBO usually refers to what a 'typical enthusiast backyard mechanic' can do in his garage with his HF box of tools. No special skills or tools. All the 'easy' stuff. Different cars will have different lists. An example is on my Jeeps 4.0L I6, I would consider the higher ratio 1.7:1 roller rockers a bolt on that can be done by most anyone. Again after air filter, BBTB, intake manifold, headers, cat back exhaust. Replacing the rear diff with a lower ratio diff assembly from an auto would be FBO but replacing the gears to a different ratio or installing/adding LSD would not be considered FBO as it requires special tools, micrometers, skills. FBO is what the 'non-professional mechanic' can do at home in his garage with a floor jack, jack stands and basic 'kit/box' tool chests. The relatively 'easy' stuff. I can do MILVs, I can't change a overhead chain driven camshaft. |

Ported head, bigger valve, bigger cam, higher compression, balanced and blueprinted, forged crank/rods/pistons, lightweight parts are not FBO.
Superchargers ?, are kinda Stage 2 FBO. |

back in my honda modding days fbo is considered I/H/E tune. anything more like cams, valves, head porting, aftermarket intake manifold, bigger tb, bigger fuel injectors is considered a stage 2 etc. fd doesnt add hp so its related to drive train upgrades like clutch and flywheel. dr tires vs all seasons. etc.
milv may it be simple, i would not consider that a fbo. sort of like adding cam gears to a car that doesnt have it. it will need to be tuned to get anything out of it. |

I dunno, I'm on the fence about it. I'm tempted to say that the 328 with higher gears is absolutely preferred by an "enthusiast / spirited driver," but I've yet to personally experience the gears in this car in particular. The stock gear ratio is definitely lazy though and designed for the typical 328i owner vs. let's say the M3 owner (enthusiast).

Its real easy to install too, i used a 5/16 craftsman wrench, a 18mm socket and my teeth to install i drove a stock 335i yesterday, im not kidding, my n/a n52 feelt faster than the 335i in 1st and 2nd gear. 6th gear passing power is amazing. sometimes ill hear a fart banger in my rear view speeding up, all i do i step on the gas and all of a sudden fart banger cant pass me. i love it. |

Not sure how this thread sits here for more than 2 weeks without any posts...this topic actually deserves to be stickied, IMHO...
