No offense to those who posted about a steel crank, yes thats you Surej, but we all know that stock Turbo cranks will last in a 10 second build. Yes some are stressed beyond the point of no return, but most lower mile turbo cranks will do fine for most regular applications. I dont buy the fact that if you rebuild your motor, you must go with a steel crank. I do agree a steel crank is the way to go if you dont mind spending the extra money for one though. In my opinion, a STD/STD turbo crank is going to hold up just fine for most people out there. You have to remember, not everyone is out to run 9's. This motor should have lasted for what Austin was planning to use it for. On the other hand, I dont know if any motor will hold up to Austin's high abusive ways but the funny thing is, he's beating the ever living piss out of a completely stock 109 shortblock that he got from me with 86K miles on it. He's put many many more miles on that motor since he bought it and all those miles were miles from hell. I dont know how many headgaskets he's blown, I really honestly dont. It seemed like that motor was getting pulled every other weekend for a while there. If a stock crank, stock caps, completely stock shortblock can take that tremendous amount of abuse, I'd say a stock Turbo crank is fine to a point. When we changed bearings on that shortblock, the original bearings still looked fantastic.
Just trying to point this out because there are a lot of uneducated/unexperienced readers out there that get scared of everything they read. Not all stock turbo cranks are worthless. Hell, I'm pretty sure there has been a 109 with Hypers and an NA crank in the 9's. Cant remember the guys name but he's on the board. I think most of everything comes down to a good tune and a good build with good clearences, good balance, and good geometery. Then of coarse a good tune to top it off.
