I have a 1999 civic ex (SOHC vtec) 5 speed. Like everything the mods I have done dont give me ENOUGH POWER therefore it is either swap of turbo. I want to swap for a DOHC. The 100 dollar question. Which would be the best engine to swap if for keeping in mind dollar to power ratio THe car has AC and I want to keep it. Now where can I find an article about this particular swap?? peace
