Welcome Alan.
You obviously won't get the same performance as your old Civic Sport but you may be surprised how lively the 1.4 Jazz can be if you are prepared to use the gearbox and let the engine rev.
Super, high octane, fuel can give a slight gain in performance across the board as does a K&N filter but only, again, at the higher revs.
Using the performance will not help your fuel consumption of course.
Vic.
