That's my point. They are designing in failure items to protect the car from being modified. It's a lot easier to NOT have a warranty claim when the motor can't develop enough boost because of a charge pipe that's a designed failure point. Now they have designed a way to also cool and comfort the intake charge with an internal radiator in the intake and additional controls. |

Again, nothing to do with stopping people from tuning their cars. If anything the DME protection is just that - protecting their investment in tuning the car's operation so it can't just be reverse engineered. |

The M88 was a great motor for it’s time. However the 2JZ is still being used by tuners to make reliable and high horsepower, well after 10 years of being discontinued. |

Closer to 440i or M4?
Thanks for the video.
Does anyone know if this B58 break down is identical to a 440i B58 engine build, oil coolant, forged parts, and variable crankshaft, etc? |

There are some differences, there is a document which out lines them but off the top of my head the main ones are;
-different head with integrated exhaust manifold with only two ports -different HPFP -different timing chain set up |

I loved the video, but am disappointed by the number of comments that complain about BMW doing some things differently.
Timing chain at the back, for example, if they have got the design and build of that chain done correctly, then it will last as long as the rest of the engine, people seem to think that chains always used to fail so for all eternity they must be made easily accessible for when they fail. What if they don't fail, why would we care where they are? Exhaust manifold in the head, heats up the engine quicker, allows control of underbonnet temperatures, shortens the distance from exhaust valves to turbo so gives better response. And the downside is that people used to put in big external manifolds to give more power, what if that isn't needed when the path from valves to turbo is so short? Sorry for the rant, I implement new IT systems, and often encounter people that just hate change so fight against anything different, and want to do things in the old way because of issues that aren't there anymore. |
