it the BMW press release it is written that it has two small turbos. But I am confused about the text as well. Technically, 2 twinscrol turbos are not possible with a 6 cylinder engine.

Your saying a single turbo cannot be mounted on a n54?
I know what they said. But I also know twin~power is the new term for the twin scroll turbo on the 2011 and newer x35i models. |

1M engine specs = z4 3.5is specs. Improvement in acceleration for both was also 0.4 from 0-100 compare to the x35i counter part. Apart from the extra cooling (just referring the engine), I couldn't see any improvements over the z4 is, just looking at its specs. The difference is the 0.4s improvement for the z4 was achieved using a DCT, while both the 135i, 1M both uses a manual transmission.
It doesn't answer the poser question, but on the surface, it seems that both engines are the same - ie twin turbo, but the results are somewhat different?

what I was referring to is putting 2 twin scroll turbos on a N54 (or any 6 cylinder engine).

However, I don't believe that this is the case since the hp/torque figures that have now been published are identical to the Z4 sDrive35is. Based on this, I suspect that the hardware and software are the same. I would, of course, be delighted if I were wrong! Neil |
