Ours was 2 wheel drive Glos Guy, so you might struggle to match it.
For those of a technical bent, the B48 engine has two tricks to maximise gas flow through the engine. First, it doesn’t use a throttle body but has a third camshaft to give variable lift to the inlet valves instead. Secondly it uses a twin scroll turbo allowing even pulses by pairing the cylinders in separate paths through the exhaust manifold.
I don’t know if any other engine does these things. I know Volvo’s don’t.
