User Name 19 Report post Posted August 28, 2009 Hi Guys I have a O2 sensor laying round my place of my 4g63t engine im doing up and wundered what the advantages of drilling a hole and getting put into the exhuast would do for the e28 its got motronic 1.3 and the e32 M30b35 in it - so is it worth putting it in there for the stock car or just let it do its own thing, seems to run pretty good most of the time since i managed to get it going.
