Hello all, first off i am new to this site and i would like to thank everyone in advance for any helpful insights that they can give me. Anyways here's my question... I want to build a custon turbo set-up on my 89' hatch whith a B16a1 swap, now i have almost all the stuff i need to complete this and i have done a lot of reasearch on the topic but it seems that i cannot find where to place the 2 o2 sensors for the best results. Anyone who has done this and has had good results please let me know. Sorry if i am beating a dead horse. Thanks for the help
