So it all happened after the turbo install. Basically 10 in/hg means your idle has to be real pour in either a boost leak or even not firing on all cylenders. The oil pressure problem could be something as simple as a bad sending unit, a bad ground, but where do the new turbo draw it's oil from? If you did ground out the postive cable i would check some of the fuses under the hood before pulling out the ecu. The vacuum leak could be the throttle seals as these are 18 year old cars. Also check to make sure the vacuum line to the gauge is good and not leaking. As for the coolant temp. guage going crazy what do you mean by that?
