@coolcool as now or never said that u can go for 12 valve 1300 cc sohc engine know as 2E ,its a carbi engine and has a normal pick and good consumptionn,
oter wise u can gor for 4EFE thats is 1300 cc 16 valve dohc efi engine .it has an excellent pick and gives u around 16 averge with charde on petrol .
other then that there are a lot of engines in market like 4efte, 4age. 1nzfe, 2nzfe and more but they are very expensive and have high maintanince cost plus due to more horse power there consumptions are a bit high
rest the choice is urs.
