I'm new to the forum, posting wise atleast. Most of what I have read on here has been invaluable, but I have a legit question that I haven't seen answered. I've got a 2002 Honda Accord LX ULEV vtec. I would love to put headers on it but I do not know how to go about doing that considering it has an O2 sensor in the manifold. Anyone have any suggestions on how to solve this issue?

Mods: AEM Short Ram Intake, 15" ICW Racing Kamikazees, Spyder headlights, 8000k HID(hi/lo beam), Turbo muffler(what the shop calls it. Don't ask.) Working on a turbo, eventually.

 

Any exhaust shop could weld another bung in for you.

Alternatively you could leave it out, but you would get a check engine light.

Why buy a header now if you are going to turbo it?

 

Because the turbo part is going to take a while. Ha. At the moment I am looking for quick fixes on gaining some extra horses out of it. How would I bypass the o2 sensor if I put a turbo in?

 

Well if you turbo it, you are going to need a new form of engine management, which will not check for ULEV stuff anyways.

 

You wouldn't happen to know where all of the ULEV sensors are, would you? I'd love to take them out entirely and throw in an aftermarket ecu that I could more easily control. In all honesty, my dream performance upgrade entails tri-charging the car. (Twin turbo + supercharger) Although I do understand a very substantial amount of modifications would have to be done in order to accomplish that. Would you happen to have any advice on raising the hp w/o a turbo? For the time being I'm going to have to keep it cheap. Ha.

 

I would think you could just get a non ULEV ECU for your year/model and put it in. I am not sure where the ULEV sensors are as I have never personally worked on one.

As far as power without a turbo, without going to crazy intake, header, exhaust, and a cam is about all there is. And with these you are going to see a huge increase in power.

Did you mean to say ARE NOT GOING to see a huge increase in power?

 

Yes Crispin I did, thank you for catching that. Been a long couple of days haha.
