TTRS doesn’t need a better crankshaft. The non turbo 07k came with a cast or forged crankshaft. The cast ones are the ones that need swapping out. 07k forged only has a 6 bolt flywheel and TTRS has 8 bolt.

I need to check etka, I’m sure the part numbers are the same. I haven’t heard of any crank failures. I have heard of many piston failures, that’s very common in gen1.
Oh, and power will not snap a crank. Torque or vibration will.sigpic

Possible the root cause might be wrong flywheel/clutch setup or something like that... Not the power of the engine will kill it, the parts around you have to modify for this power to handle it.
Only wanted to mention it.
