Cheers for that ginge, you learn something new every day.
This wont be much help to you, but it could be to someone else in the future. For a 1.8 Zetec engine I've been told ZX9R carbs work well with the engine, this is without a rolling road session.
This proves ginge's point as the 1.8 zetec is supposed to put out 145bhp and the ZX9R carbs are from an engine which puts out 144bhp....
