I'm gearing up for my turbo replacement and have a few questions...
1) I'm looking to pre-emptively purchase a Timesert kit to fix a few bolts I know will probably not tighten down after pulling the intake this time around. Does anyone know offhand what size (eg: M7 X 1.00) that the intake and fuel rail bolts are? I've done a couple helicoils and had a helluva time feeling like I was lined up straight at the angle I had to work with that hand turner on the cutting blade. It seems like it's so easy to get that hole started crooked. I found these taps on the Timesert site - looks cool as they allow you to use a ratchet - any suggestions? http://www.timesert.com/html/usefultools.html
2) What parts do I need to do an AOS re-seal? Is it just the two o-rings?
3) What parts do I need to redo the o-ring on the dipstick? I can't find those on pelican.
I'm replacing my stock turbo with a Vitesse Stage 2. I bought the turbo from docwyte though - so I may be missing some stuff that was originally shipped with the turbo.
In John's documentation - I read this.
What is the paper gasket? Is this unique to John's install or is there a part I need to pick up or can you just make this thing?
What else is good to do 'while you're in there'?

"At the base of the turbo (Oil drain hole), keep the "OLD" rubber O-ring on the
engine mount and use the supplied paper gasket between mount & Turbo."

The AOS is just two o-rings.
The dipstick is just one o-ring.
The paper gasket helps to seal the oil drain for the center cartridge of the turbo. KKK center cartridges are a circular hole, while John uses a center cartridge with a square hole. It's there for added sealing.
You will have to do one of two things with the turbo coolant pipe. Either modify it by cutting/extending/bending, or use the adapter supplied by John. I chose to use the adapter and therefore had to delete the front manifold bracket. All it really does is hold up the balance shaft heat shield, so I fabricated a bracket to clear the waterpipe. Also NAPA sells a low profile temperature sensor that you can install in place of the old sensor if you have issues with it clearing the manifold.

Its been so long since i did this but if i remember right you need a T3/T4 oil drain gasket. This basically goes inbetween the original o-ring and the oil outlet flange on the turbo.
