An oil that i reccomend that has been proven to me on a 800Whp stealth (awd-tt)
Amsoil , i need to ask him what weight it was, i think it was on the side of 0w-30.
pretained a high pressure on cold startups, and had some awesome add-packing to it.
he ended up bending some rods, and breaking #3, his crank was also bent. The Crazy part was, none of his journals were Showing any signs of scarring. Which if you think about the twisting forces that were applied during the breaking/bending of the rods, thats almost unbelievable.
oil that contain its viscosity is a great thing. Plus after some hard running the amsoil, while breakdown will gain viscosity on the top end, so a harsh-using of amsoil will go from a 30 weight to a 40, just so you have extra cushion from the wear and heat, enough to say HEY! CHANGE YOUR OIL, GET THIS DIRT OUTTA HERE!
-FILTRATION!!!-
If your serious about filtration and oiling issues, you should check out

read up on the oil filters (spin-on), i've run a canton and i love taking it apart to see the residue that it gets before it gets sent through my oil cooler and such. Non-bypass is the way to go.
(100 bucks for the filter, yet the elements are 15 bucks. so heck yea, its worth it if you love your car!)
Well, thats my .02 hope some of that helped out a little guys.
