And yes, it is modified but even then, Underdog Racing (which specialized in a few toyota platforms) suggest I stick with the factory recommended oil. I personally don't know what's better or worse.
But if GC is better because it runs close to a 40 weight oil, doesnt that mean any oil with a 5W40 rating would be better regardless? I'm not sure what additives do but all things considered, I think price will drive me to GC since it's only $7/qt.

http://www.renewablelube.com/ These fellows are a strange lot. Maybe I missed it, but I can't find data of ANY sort on their web page. The best they can do for a FAQ is point to several BITOG threads! There is no hint of API certs, or even a lone XOM-like vague claim regarding their lubricant's characteristics. For all we know, they are selling Castor oil and liquefied cow farts? Hmmmm ... that might work pretty well!
All that boost makes me want to use slightly thicker oil, with better HTHS values. For what VERY little it's worth, I'd suggest Redline in 10-40 or so. It's GRP5, temp resistant, 4.7 cP high temp high shear, and lots of zinc, moly and phosphorus anti-wear goodies.
M1 15w-50EP wouldn't hurt anything either. It has similar HTHS numbers, so isn't much 'thicker' at the bearing level than a solid 40w. Maybe an M1 Frankenmix? 50:50 0w40 and 15w50ep, just for fun?
Whichever oil you choose, periodic UOAs sound like a good idea of you're leaning on the motor often. And be sure to post the results here for us UOA junkies!
