can i use my stock O2 sensor on the HF manifold bolted on to a turbo? i heard its not good, i will be making a bung on my downpipe anyhow should i make 2?

 

its fine in the manifold, everyone has there own opinion though but i ran mine like that and it was fine.

 

I would just plug it up on the manifold with a bolt you can get from NAPA. And then put the o2 sensor after the turbo. Look at any turbo car, they are always after the turbo.

 

you'll be fine with the stock. i haven't had a problem for years. if you get a wideband o2, then you should put it after the turbo.

 

you will be fine having it there. I used to have mine there and it was fine. Just don't hook your wideband there because it will throw the readings all off and give you random lean spikes in your data. Trust me i've tried it already :P.

 

ya for sure my WBO2 is going to be after the turbo.

 

use it, plug it, or put an EGT probe there. Either way I'd make use of it somehow since it's already there.
