Hi darkhorse I have a parts manual for the 3.6 turbo which I can email to you, if you pm me your email address I will send it.
Coil packs issues tend to be terminal, in that once they go that's it.
I stripped my Turbo down a few years ago and it wasn't as bad a job as I'd expected, the main PIA is rusted studs and corroded nuts that crumble before your eyes. The engines are pretty much bomb proof, if you get the chance when it's a apart change the main water pump, they are a weak point and whilst everything's apart it's so much easier than in 6 months time. For a water pump go to Autodoc as they are a quarter of the price that Porsche charge and they are a genuine part. Also the main drive belt as well as they only cost £30.
One word of warning, the new coil packs are different to the old coil packs so you will need 5 new style and one old style, the new slightly larger Beru coil pack won't fit behind the turbo actuator on I think the drivers side and no amount of 'adjustment' will make them fit. So if your getting packs from Design 911 mention this to them as they got me an old style one which took about a week to get.
