Dimension of the sigma engine

[piple]

I'll have +2 which need a new engine. I think of a swap to a sigma engine.

Due to regulations, I am not allowd to use a 1.8 or 2.0 Zetec or a Duratec. Additionally I am not allowed to modify the chassis.

So my question about the overall size of the engine. Has it the same lenght as the 1.8 or 2.0?
