Starting point is look for damage, worn bushes etc and get a full wheel alignment.

Ok that indicates that oil fumes are getting though the catch can so you need to baffle the catch can and/or put an air/oil seperator (could be another baffled catch can) into the line from the catch can to the turbo intake. If there is masses of oil coming out at WOT refer to the oil control thread for more answers.

Or read my post above?

That's the wrong ecu. It doesn't matter if its manual or auto but the OV300 is a Hitachi ecu for a series 1 Stagea that has the R33 engine. You need a Jecs ecu for a series 2 Stagea which had the Neo engine such as .23710 aa501 (or an R34 GTT ecu).

She'll be right mate. Could go for years with a good tune. Is the GT3076 a worthwhile upgrade? How much power are you making now and what is your goal for the 3076? Oh I see you are making 287rwkw. Are you sure its worth changing the turbo?

Two mirrors: http://www.trademe.co.nz/motors/car-parts-accessories/nissan/exterior/auction-792269100.htm

Pull the plugs. Squirt a little oil into each cylinder. Retest. If the compression comes up it its more likely to be rings. If not then valves. But having said that with the uniformity that you have its more likely rings.

265 is middle of the range for 10in rims - should be fine.

120 psi across all 6 - it could go for a few more years depending on how you treat it. Instead of venting your catch can plumb it to your turbo intake with an oil/air seperator in the line.

Have you tried Nissan? I could probably find a second hand mirror. Is yours S1 or S2 (although they are probably the same)?

O2 sensor is only of interest at idle or constant speed so not likely to be part of your problem. What about new plugs and a clean air filter element?

GTST or any R32 or R33 seats will fit.

9 and 7 too hard. I recommend (and use) Bisteins. I have Tein springs but stockers may be ok or Eibach. If you must have coil overs there are a few C34 owners happy with their BCs (don't know anyone with the coil overs you mention).

I used to have a set of Recaros out of a Honda Euro - with the right base and a set of sliders you can fit most seats. Here's the kind of base I used (fits R32 R33 and Stagea):

Since I'm no expert on cams I would buy one from Kelfords rather than Tomei because Kellfords make a lot of custom cams and if you tell them what your set up is and what you want from it I would suggest they would supply the right gear.

Do some research. Its not a popularity contest. Get a quality full synthetic for the track.

Get the same size all round wheels and tyres.

Don't know much about the "how" but I have been watching a fair bit of rallycross which involves 4 lap sprint races so it is very important to get off the line quickly and try to be first into the corner and ALL the cars use anti lag.

Masochist!

Post up your wheel alignment.

I want a hoist

No idea - mine doesn't have it. Here is a pic from the Cusco web site: http://www.cusco.co.jp/en/catalog/pdf_catalogue_suspension_parts.html

Yep GTR castor rods fit the Stagea and so do the GTR camber arms.

You need a power bar - lucky you haven't stuffed your ratchet. Then you can slip a length of pipe over the handle of the power bar for more leverage. Can't see my car for reference atm but is there a nut on the other side you could try? Also give the bolt a couple of good blows with a hammer to try to break the bond. Not so many that you deform the head.

Well you can buy Japanese brand named stuff for up to $1000 or you can just get a sandwich plate with built in thermostat for about $100 some rubber hose (yes it works fine) and a small oil cooler radiator (spend the money on a good one). I'm in NZ so can't point you to the shops. (Like this - not sure if this exact one will fit your car but I have a Mocal one for my RB) http://www.ebay.com.au/itm/UNI-MOCAL-OTSP1X-OIL-COOLER-SANDWICH-TAKE-OFF-PLATE-WITH-THERMOSTAT-SEAL-SR-/121385762319?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item1c4327be0f
