How did he get away with such a swop 
I'm still planning on getting an SR20DE (no T) under my hood.

It must have been the engine cover. That's the best part about
European cars. They all have those full plastic covers that hide
the engine. 
Anyway, if your driving pattern is consistent, and you don't go
rounding too much, large engines are very frugal at low rpms.
I remember my holiday in Australia. I drove 2000+km in a 4L Ford
Falcon. Averaged about 9km per litre (that's about 600+ km per
tankful), and I was actually going at an average of 150kmh. The
thing about those Aussie cars, even at 150kmh, the engine was at
2200rpm (at 110kmh it was around 1600rpm).
