well looks like the old girl still has life left in her after all.turns out that the root of the problem was the oil supply line to the turbo, the turbo was getting too much oilpressure which inturn was causing oil to be pushed past the seals.installed a restrictor inline with the feed line and it stopped smoking for a bit till i boosted, turns out that i had mad oil in the ic and the pipework.also i was maxing out the maf that was on there (it was supposed to be a z32 but it wasnt so i have no idea what it is) and the maf was covered in oil.got my hands on a real z32 maf and cleaned out the charge pipes and the intercooler and reassmbled the charge pipes, low and behold the car runs great and doesnt smoke at all.rechipped the ecu to control the 550's and the z32 maf and looks good so far, cold start is absolutely horrific but once it comes out of cold start its mint.now i need to figure out an uprated alternator because when my fans kick on at idle it trys to die because of the current draw.oh and i have traction problems now :p

Good to hear it. Yeah I need one of those alternators too lol. Mine dips down to 13.3 and sometimes even 12.8 when I stop but then goes right back up to 13.7 after the fans shut off. Ahh well the joy.
