hello!

i've decided na to have my litace's 2c-t engine opened in order to removed the rust and sludge bulidup that the flush could not flush at all....and i decided also to have it ported and polished....

my question is, is it true that i'll gain somehow improvement on my engine? pwede paki list naman dis/advantages ng port and polish?

and my second query kung palitan ko ng oversize ung piston rings ko, anu pala dis/advantage ko..kung may increase sa power how much?fuel consumption will increase, pero up to where?

kasi para isang gawaan nalang...
