Amsoil AMO 10w-40 or Redline 10w-30 or 10w-40.
Spell checker not working?
Ya know, thin oils might have a bit of a problem protecting the bearings if you end up with detonation or shock loading from something like improper timing.
Having dealt with plenty of turbo road race cars, the only thing that protected the bearings under unfortunate situations was thicker oils.
In this case, the 10-40, and in particuar the Redline oil has a bit more viscosity.
I use M1 15-50 silver cap, or (I think it's better) M1 v-twin 20-50.
Plenty of 400HP Mazda Miatas can't be wrong. By the way a high boost turbo Miata will eat rod bearings using 10-30 syn.

Dureing the winter I would run Redline 5W40 and if consumption is not an issue stick with that! If you find consumption is an issue go to Redline 10W40 for the warm months!
Just not sure... What is a gt3000?
Is this a 3000GT VR4?
This will go against everyone on here but it's my own experience... With the GN, I've had best luck with dino 20-50 with bearing and ring wear. This is with multiple tear downs that I personally did all the measurements before and after, and 1,000 mile or sooner changes.
Take it for what it's worth. Not sure about your motor, mine is a high torque, high boost, relatively low rpm motor. I think the thicker oil could possibley help if you get a little greedy from time to time with the tuning like I tend to do.

The part that throws me off is, that he says hp at the rear wheels, which means for sure not one of the lower two models and I have never heard of someone disabling the AWD for just RWD on a VR4.

M1 v-twin 20-50
I saw this oil at Walmart the other day. I`ve often wondered about it,not to run it,but just curiosity. Bottle looked cool though! Black bottle with "racing" written on the label. But it made me wonder if motorcycle oil was any different than car oil. Me,I don`t intend to run a 20W50,but it just looked interesting.
On your GT,I too was wondering about the "rear wheels". Do those cars (VR4`s) put more usable power to the rear wheels or does it evenly distribute to all 4 wheels wherever it`s needed?

It's because most 30wts shear down quickly in a turbo engine. But it makes for a great qualifying/dragrace oil
A 40wt would keep the bearings, turbo, and (hla or solid) lifters happier.
I'd use 5W40 HDEO at a minimum, ACEA A3/B3/B4 stuff. Shell Rotella has been showing good wear numbers. RLI 5W40 (Audi RS4 veggie oil) has been even better. Amsoil or Redline 40wt? Joe Gibbs?
I think a 50wt would be too thick unless it was summer or you had large bearing clearances.
A UOA would be a good idea too http://www.dysonanalysis.com

While 500 sounds like a lot HP (it is!), there are enough good old USA NA engines with huge displacement pushing well over 500 hp. I think what pushes the oil here are the turbos and the tightness of lubricated clearances. (which I assume you aren't changing). What are others using with success?
That said - the only oils I would consider in the SAE 30 cSt @ 100°C range are straight SAE 30's or more specifically only an oil with no VII. If you want to step up in viscosity then some oils with small amounts of VII's may be acceptable. I also assume you won't be starting this engine in the dead of winter?
Amsoil ACD SAE 30
Amsoil AME 15W-40
Amsoil TRO 20W-50 Racing oil

Probably would use Redline if you want to spend a lot of money but think Pennzoil Plat would work fine for you and save you money.

The main difference is the 500hp is spread out over only 6 cylinders so there's a little more load on each cylinder. Still, I see your point, there are plenty of 700+hp V8s that live a normal healthy life.

You're in Ohio, I'd say it's a no brainer to get a RLI Biosyn oil, possibly the 5w40.

I'd agree. Give Bill Garmier over at Renewable Lubricants a call.
