Okay, So I got my head back from the machinist today, as I was looking it over I noticed a allen head bolt in the center of the head just above the 2nd and 3rd cylinder intake ports. It looks like it's a plug comming right off the oil feed for the cams. I think it would make a really easy place to tap in for turbo feed or Oil pressure guage. BTW this is a 3gp JDM B20A.. does anyone do it like this?? It was my understanding that the common way to do it was to tee off of the oil pressure sensor.. but this looks like it's in the same line, just down stream a little..
