Hooking up 02's
 

This car was a n20 car and was tuned with ls1 edit. I am switching to HPT. I currantly have stock 02's. Do I simply replace these with widebands GM PN 12580698 back to stock PCM or to new VCM. Thanks for any info.

does anyone know?

Nope...What you need to do is actually buy a wideband O2 controller and sensor from AEM, Innovate, Dynotune, or another company as such... With these you're only going to have one unless you go with something like FAST which has a dual WB system... You can place them in the stock bungs BUT put them in front of the CATS because they will burn out after... If you replace the stock one with it make sure that it has a narrowband output that you wire into the stock harness for the signal and also ground the ground wire in the stock O2 harness...If you're confused ask questions and I'll try to answer them or someone else on here can... Goodluck.

I appriciate the info I've got it now I will just leave the stock ones and add the wideband. That's why I ask so many questions on here about turbo stuff because I have always ran n2o. and am learning about this on my own from ground up. I am asking just to gain knowledge from people who have don it before. THANKS AGAIN.

No problem... So you're going to run turbo?? I think that you're supposed to have it no further away than 18" or closer to the turbo... Goodluck and post some pics...
