At this current moment I plan on going with Perrin's instructions for installing the uppipe. (I got the ATR). I'd rather not remove the turbo if I don't have to. At any rate, where do you jack up the engine per the instructions? (Like, where is it safe?) Any tips before I do this? Also... the O2 sensor wrench, is this a standard socket wrench just really big or do I really need to go buy a special wrench? Finally, does anyone have torque specs for the bolts? I hate not torqueing things properly. Thanks in advance!
