Got to admit the Germans have never been very good at extracting power from small n.a unlike their jap counterparts. Where our 1.8 make a low 100+ an integra type r will produce closer to 200, whats more the standard 1.8 agn will hardly take 200bhp reliably while the dc2 engine will be reliable for over 400bhp without doing anything to the engine, a few of my mates just run a precision turbo kit or supercharge it.
Personally if I was after cheap power I would just use a decompression plate and run a g60 supercharger
