Not even 2 days into the single turbo life and I think my o2 sensors are fried, or I just have them in the wrong place. When I start up both AFR1 and AFR2 start out around 13 or 14 and then about 10 seconds AFR1 slowly goes up to 20. I'm getting codes:
2A2B Fuel mixture control
29E0 Fuel mixture control
2CAA Lambdaprobe before catalyst, temperature
2CA6 Lambdaprobe heating in front of catalytic converter, function

I knew the factory o2 sensors weren't going to last long with the new setup but I didn't think it would be this fast. I want the ADV o2 sensors but I don't have the $400 to order them right now. So is it alright to drive it right now but just not get on just like cruising low rpms? Or will this hurt the engine just by cruising?

sorry to see all the problems you been having with the install. I think you best bet is to get the ADV sensors and reflash.

Ouch. You can try a set of stock sensors off Amazon Prime for now. I forget which one but one of the stock sensors is available for less than $100. It's the one with the longer lead. And since the sensors are the same, you can buy two of these and use them for a cheap solution.

Yea I was kinda expecting it with doing something like this but it is what it is. Talked to Chris and I'm going to order some adv sensors today or tomorrow

Thanks for the info but I dont feel like wasting money if the factory o2's are just going to be fried after a day.

I don't see any pics. Has this build started yet?
Yup I finished it last weekend. Sorry for no pics I've been pretty busy at work this week and there's still some things I need to touch up on some things to get it where I'm satisfied with it. Took this pic when I was still working on it so sorry its a bit messy.

No worries man. Looks like a very clean build though from the description. Thanks for the pic too.

Just finished up installing my catch cans minus the one line to the turbo which I'll do tomorrow. I need to order some angle fittings so the lines can look a little better. I want all the lines in my engine bay to be braided stainless steel eventually. All the fittings and lines right now are just what I could find around in the stores near me. Also I saw a oil leak on the oil drain for the turbo so tomorrow I need to take the turbo back off and adjust the oil drain fitting. Waiting on Chris to reply so I can order some o2 sensors. I'm dying to drive it and hear what it sounds like on full boost. Right now I'm just on wastegate pressure which is 11.6 psi. But I've only gone up to 4 psi on a small pull before my o2 fried and I don't want to push it with a bad o2 in right now.

Should be getting my adv sensors sometime this weekend. Hopefully I'll be able to put some logs up to see if its running good. I know that the iat are way to high but I'm going to get the vrsf 7.5 race IC sometime soon. Also last week I took the turbo off to adjust the oil drain cause it was leaking so I tightened it up pretty good and the screws going into the turbo for the oil drain. I haven't been driving it at all this week but I started it up yesterday and was still leaking. There's not enough room to to see if its coming from oil drain plate or the oil drain spout.

@markyb0 I would make sure that the drain has good flow going back into the block. if flow is too restricted it will find a way out somewhere else. But you make just have a bad gasket it sounds like.

I have the oil drain on the bottom pointing towards the block so flow should be good but yea that's what I was thinking of buying a new gasket. I'm just paranoid about the oil getting on turbo blanket or the exhaust wrap and catching fire.

Looked at the drain again today and it seems like the leak is coming from the drain flange threads and the drain spout that came with the docrace kit not the gasket. When I took it off last weekend I tightened it to the point where it felt like if I went anymore it was going to snap. So I don't know what else to do. Has anyone put some type of loctite or gasket maker on the threads of the oil drain? Or should I just invest in a vibrant threaded oil drain kit?

Please Update when U get the advs installed .

I Fried 2 oem o2s already with st.
Will do
