ya sure...
btw do u have auto or manual tranny... mine is auto so u can imagine performance
well G493 produces something arnd 110 HP...
well turbo version of 4G93 1.8 is also there... but i have no idea how much alteration will be required for that...
4G63 SOHC(2.0) is another option but its pretty much expensive...
and wat is ur range for the swap ?? n how much the 1.8 swap costed ur friend ... did he do a suspension upgrade aswell
why dont u try some performance filters etc... dont forget that mits is not as light body as corolla or baleno...
