Need help buliding 03 ex
I'm stuck in Iraq, racking up the $ and I have a 2001 civic dx at home! MY father bought me an 03 ex engine, since I blew mine up a few months back! Now before I put the engine in my car I want to build it! I have a set of DC Sports 4 into 1 headers on the way, and a long list of other parts I want, I need help finding some of these parts! Also, I'm new to the import tuning world, so I may need asstance in modifying my plan! So heres what I wanted to do........ AEM cai, or V2 can't decide! apexi vtec controller, AEM pulley kit, AEM Cam gears, exaust(brand or style????) Dh-rachin.com 10:8:1 oversized pistons and rods, dh-racing.com throttle body, throttle body spacer, dh-racing.com valve springs, titanium retainers, and oversized valves! I also need to know what kinda machine work will need to be done, keep in mind I will be running a NX system 50-75 shot! any help you can provide will be helpful! I plan on spending $5,000 or less if that helps! also how much horse power should i expect to gain? Titanium Metallic. You got a problem with that?

K20 would honestly be the way to go, but if you are going to go with the EX motor you have, Id say Port/Polish/Stroke, dont worry about the NOS (since the engine wouldnt be able to hold much) and then go with the Unorthodox Pulleys, DC Ceramic Coated headers, Apex'i VTEC/AFC controllers & N1 exhuast. As far as pistons/rods go, Id say to do a lil more research into those, dont be afraid to spend a lil more money for these and lag on the VTEC/AFC controllers. These go bad and $$$ out the door.
yes, but where would i be able to find a set of pistons and rods, besides dh-racing.com, and i already have dc sport ceramic coated headers on the way!!!! whats an afc controller??? and is an apexi vtec controller worth it?

AFC is a Air/Fuel Controller and Apex'i makes a nice one. As far as pistons and rods, Im not sure if JE has made anything yet, but they usually make a really good product. If you are going to turbo your vic, get a complete kit as they have everything you need minus the AFC/VTEC Controllers. If you are going to go for a lot of power, then yes a VTEC controller would be worth it.
