heated 02 sensor, or no? I've searched all around for the answer to this question, and haven't found a direct answer.
I'm planning on buying a set of longtube headers for an automatic 1993 lt1 camaro, and was wondering if I will HAVE to buy the heated 02 sensors or not. I know I will need the extensions, but the sensors? It seems like i've seen guys use stock sensors, and others have also bought heated.
Any help would be much appreciated. Thanks
It has an airfoil, thermostat, no cat, and will in the next year have nitrous, stall, cam, ported heads, and everything to go with the cam swap.

YES YOU MUST do it...its a no brainer..it will not run properly AND you will not tune it....Case and point

I gave reasons why you should convert to heated O2s. Can you give reasons why it isn't necessary? At least give the OP something to think about and make him make an educated choice.

Well, I have a 93 with long tubes on it for quite some time. I was curious to see if it was running in closed loop since I never did the heated o2s. I hooked up a scanner and monitored loop status and o2 activity for a month of daily driving. It only drops into open loop on extended idling, more than 3 minutes. This was good enough for me and I have left it like that for about a year now with no ill effects.

im not sure if your being funny or not, but that is a false statement. on a side note i enjoy your sig everytime i read it, lol
His car will run on stock 1 wire O2s, of course not as good as if he had heated.
No matter how you look at it...just like you nay sayers Cars and Like mine Was .. it will not run at it potential,It will foul plugs quicker and miss fire,it will bounce in and out of CL at crusing speeds and idle,it will use more gas,it may have idle issues(mine sure did), it will be hard to tune if at all... thicker metal steel headers or wrapping them will retain more heat and may help the situation but will still be running on old technology and not at Potential to complement an Ed Wright tune . do the conversion its just to simple and worth it not to ...

So i'm guessing its just one of those deals of how the specific car will react to it. I can understand where everyone is coming from now.. I'm not extremely picky about the car, so I'm not going to worry about the heated sensors until I run it without them and see how it will react..
Thanks for all the help!

O2 sensors must be at a very high temperature in order to provide accurate readings. Prior to 1994 the one-wire non-heated sensors relied on the engine exhaust to heat them up. 94+ sensors use a heated element to speed up the heating process.
x2 on this and that is one of the many reasons most went to heated O2's around the same time is that it offers a better more reliable reading of the AFR for the new faster PCM.
