here are some pics of my z06 mods... i bought the car like this. i kno it has corsa exhaust and some type of cam, k&n filter,msd plug wires, but i can't identify the headers or x pipe.

plus, there is a picture of the sensor that looks to me to be unplugged... it's located on the passanger side back near the firewall... any help would be greatly appreciated.

 

more pics

 

even more pics

 

Not really too sure on the brands of your mods. Looks like you've or LS6 heads (which a z06 should), ported or not who knows. That connector that's not plugged in looks like it's for a 02 sensor, which was probably removed when the headers went in.

 

Those headers are identical to my old TPIS set.

 

I think it is Tpis as well. The color of the H pipe is what I was looking when I called them up. Same look and thickness. Plus you have the cats at the front of the car. LG puts them in the rear.

 

Is the tpis brand a decent header,xpipe combo? thanks for your help guys... i think a dyno run will answer some questions.... i know there is a cam but i don't know what kinda or sizes..


isn't there something that i can clip onto that unplugged 02 sensor (click on the 4th pic in my first post) that can bypass it and stop throwing codes?

 

TPIS is a good company. And one way to get around the code BS is to run o2 simulators if you have an offroad midpipe. Or, just put some black electrical tape over the SES light. lol

 

can you elaberate on "running 02 simulators" .. is that something i buy or what.. thanks for helping a newbie out

 

You have cats. Just plug the 02 sensor back in or go buy new ones if you still are throwing codes. If you ever run off road pipe meaning no cats you have an 0b2 car which means instead of the normal sniff test they plug a computer up to yours to see if you’re throwing any emissions codes. If you are you fail. The sims cover up the codes and trick the computer into thinking everything is fine, in a sort of easy way to explain it.

 

From what Ive been told you can turn off the O2 sensors in the computer when you tune it. Mine where turned off due to eventually we will not run cats. If the car was tuned you probably dont have anything to worry about because usually for emissions they just plug your car in to see if it is blowing any codes.

 

ok so i have found out that have k&n filter w/ zip-tie ,tpis headers and Random Technologies x-pipe and cats and corsa exhaust as well as various msd things.... still have no idea what type of cam or tune. i'm adding a 125 shot with new ngk tr6's....

 

You don't know what kind of tune and you're going to spray?!

 

oh i should have mentiond that i'm getting that check along with a dyno run march 12th.... the bottle isn't going in till after that.... it's to cold here to install it and there is 12 inches of snow out side so i'm not driving till the 12th... sorry for the confusion...

 

I'd track down the previous owner and find out for sure. Just my .02

 

I def agree find out what he did if he even knows. But chances are if he did not tune the rear o2's out he probably did not tune the car period for the cam. Any shop or experianced tuner would have deleted the rear O2's I always do along with the AIR setup (but who knows thats up to the individual). You can delete the Rear O2 sensor but not the front ones. You need the fronts to help your computer determine the its A/F. Basically. And if the car was not tuned which i am thinking no if you got some codes there, then chances are you do not have a cam that is too radical maybe a earlier 221-230 duration type cam with less then a 590 lift and 112-114 LSA other wise you would have some issues. Check and see if he drilled into the TB. That will also tell you if its tuned for the cam. Was how many compensate for the idle issues of cams before they tuned them if ever By all means figureing out the cam is damn near impossible unless you pull it and mic it or cam doc it.

 

the rears are deleted... i found out that one of the 02 simms fell off.... which i heard happens sometimes. so i just have to replace that.
