hi guys.

im driving a satria neo 1.6..
got it like a year and a half ago..

so the problems im facing now is...
my conrods are srewed ( they said it might infect the lifter as well )
:(

so the thing is.. how much is the usuall price for replacing it to a new ones?

and is it possible to change the conrod to "performance conrod" ( i dont know wheter it actually exist?

and if it does.. how much do i have to keep in mind??

sorry asking these noob quests...
