I think everyone is missing the point here. All turbo engines are very tunable, I'm sure both Dinan and BMW will offer performance software packages nearly immediately for the new 328, as will many aftermarket tuners. The point is that a tuned 328 F30 will be in the neighborhood performance-wise of a stock F30 335. Hell, a stock F30 328 is only 0.4 seconds slower to 60 mph according to BMW.

The Bluetooth retrofit isn't that bad. One of my friends bought the module from a salvage yard and saved big time. I went the route of a visor mounted BT device. Works great!

Are you saying new F10 M5 which is pushing 20+ stock is less reliable than tuned N54? |

Good point. Here's hoping BMW has made the N20 as capable of high boost as the M5 engine. I just have a feeling they may not have. No proof of that..just a feeling.

The N20 is intended for a totally different market. It will therefore be built with less expensive and less capable engine internals and cooling system that meet the design specs. The engine will still be high quality, just not as high quality (or as expensive) as that from the M5. The point here is that both should be reliable in terms of what they have been designed for. The key point is just that - the design specification. Its not just about the boost you run. Moving the N20 to much higher boost moves the power output of that engine outside of the design specifcation. Such an increase requires upgrading other effected parts in order to maintain factory reliability specs. |

You cant just simply go by amount of boost and determine which engine is more reliable just based on that BTW, with 20psi, my car barely gets to 210F BMW did great job with cooling in S63 |

You better get the manual tranny then... who wants to push that measly power through 8 gears? .. but 6-cylinder power in a 4-banger package w/ a tune should be fun in the right set up... just imagine the turbo whistle

And so...
Stock for stock this is not an STI EVO killer. Tuned, it may achieve similar numbers, but then the STI and EVO can also be tuned beyond their stock numbers. So, it's not going to "kill" those cars at all. I think this new engine is excellent. The true comparison is between the A4 and C class. The new 3 will spank them in stock form and potentially beat them in tuned form. Audi and MB have their work cut out for them yet again. And those cars still don't quite match the 3's driving dynamics. This new 3 appears to be excellent! I like it, a lot. Last edited by RPM90; 02-02-2012 at 04:14 PM.. |

Even my 135i has a tiny bit of lag, tiny but still there, and on certain driving conditions the lag is even greater. The Audi 2.0T has a bit more lag than my 135i, but still not bad at all. This new BMW 2.0T should have no more lag than Audi's, and it will probably be less. When you tune it there is no inherent reason for greater lag when using the same turbo. When you go to a larger turbo that's when greater lag can come into play. So I don't expect a tuned 2.0T to have any greater lag than it has in stock form. Stock x35i to tuned x328i will be a close match, but overall the x35i is not stressed in stock form like the N20 will be when it's tuned. There is no replacement for displacement still holds true even for turbo engines. |

Even if it's 20-30hp less it'll still be great considering it'll be noticeably lighter, especially up front. Less weight means better power to weight ratio, which will negate some of the lower hp of the tuned N20. I agree the sound of the NA 3.0 six is beautiful. But in turbo form my 135i engine doesn't sound as cool as the NA 3.0 screaming at 6K rpm. Turbo's mute the awesome sound of a high quality NA like the BMW 3.0. I'm sure the N20 won't sound as spectacular as the NA 3.0, so that's one negative. But the overall positives are great ones. |

Efficient n stock form.
Tune it to those levels and you use fuel like any engine making that kind of power, when the power is used. My 135i gets about 21-22mpg in normal everyday driving. But if I run it with all the glorious 300hp it has MPG DIVES, like any engine would. If you want power and performance MPG should not be on your top 3 list. |

Don't confuse error-prone dyno numbers that anyone can inflate or deflate at will with hp numbers calculated on an engine dyno, as BMW does. Their numbers are pretty accurate. Also, don't confuse the N55 with the N54. It would indeed seem that some N54 of the first two years of its production (in particular press cars...) made more than the 306hp at the crank that they were advertised for. Later models were pretty much as advertised, with the usual variance of 5% that you will see with any measuring that you do. Quote:

I had the N54 when it first came out, and no problems...worst case scenario they replace it and i get a nice loaner.
