Really depends on what u need .
If u are the sayang car type of ppl , drive at speed limit and do not floor the car. Just slow n steady. 2.4 will be good enoughm
Im using 2.4 anh20. Correct , just pump n drive, no issue watsoever , peace of mind , roadtax also not headache. Gb cvt is best , 110kmjh @ 2100rpm . Pickup also good . Engine very reliable . Nothing much to complain. Family happy,im happy ,wallet also happy. Btw do add ultra racing fullset , not expensive 2.1k can get , change ur vf from sampan to equiminity ... : D
