I think the problem lies in the fact that everyone wants more performance. It's a little like using nitrous, people want to keep jetting it up until they reach the point where the engine can no longer withstand the additional H.P. To me it makes sense to keep your goals realistic but not scrimp on what's in your engine. I'm not advocating the fact that everyone needs a forged crank, girdle, roller cam etc. but it doesn't makes sense to downgrade the crankshaft from what comes standard in the turbo application. GM opted to put a rolled fillet crank in the motor for good reason. People far smarter than you and I decided it was necessary. A good used crank isn't that expensive. Don't short change yourself.
