I was wondering if I can get guidance on where I should take the next step to building up my lancer. I herd mix information about not to engine swap such as with an 4g63 engine and I herd I should keep the one I have and to just tune it, get aftermarket headers, intake and etc?

 

If you want to go faster, save your pesos and buy an Evo. Do not bother with modifying a lancer. You will end up spending enough to have purchased an Evo, and the car will not be anywhere near as high performing and will be worth less than a stock lancer.
