Engine

I was at Frankfurt IAA and happen to saw the new engine of B3 Biturbo (410-420HP, 600NM by their spec).

It seems to be an n55, except a few changes...
Intercooler is larger than the factory one, pipes are different and yes, they use those old-school single-scroll turbos from n54 instead of using n55 twin-scroll turbo.

I dont know wheather thos n54 factory singles are modified or not.
