98 honda civic ex D15 with D16 headers HELP!
 

Hello guys,

So i got this 98 civic ex and its pretty beat up engine wise. It has 175k miles on it and i have no idea what the previous owners have done to it. I know they put a d16 headers on it but other than that i have no idea. Basically, i want to know what should i replace on the engine to make it last longer and eventually turbo charge it? I already bought all the gaskets for it and the valve cover bolts. But as far as fuel injectors etc etc please let me know what i can do to make this car run smooth and fast. Thanks!
