if u compare wif another mira engine,L2 carb fuel consumption is higher,not that much la,i dun know the fuel consumption,but it wont be that bad...about the performance,quite ok,im not that impressed though...it onli has a lower comp. piston compare to other model,so can boost high...can titik L200 doesnt mean it is more powerful...even my L5 auto can titik L2 manual a'time if i wanna too,but dat doesnt mean mine is more powerful,u get the picture...i recommend u to go for L2 efi turbo engine...easier on sparepart,n later if u wanna do extreme modification L2 is the way 2 go...
