The car is OBD-0 with 2 O2 sensors. I've made everything else for the turbo kit and I'm designing the downpipe tonight. If I want it welded by the weekend I need to know where to put the O2 bungs at. Any suggestions please.

Application:
B16A1 PR3 ECU
Custom Manifold
2 1/2" downpipe

 

I would probably put the first one about 6" away from the turbo and the the second one right underneeth the oil filter..

Any other opinons, I'm a little worried because stock N/a both o2's are right next to each other, does this matter in an FI setup?

 

good question, im going turbo here this week and i also have the two o2 sensor problem on my b16a, i was told you could bypass one o2 sensor and go off of one alone. but i dont know, is it hard to just weld on another o2 sensor bung? would a local exhaust shop have these? hmm. questions to answer before this week.

 

There is an O2 bung on my turbo where the "O2 Housing" is. I think I might just use that spot and splice the two together for a temporary solution. It's only like 2 inches after the turbine housing so that worries me a little.

 

Yep, throw it onto the o2 housing.
