Ok so I've done a lot of reading on which crankshaft from an lq4 will bolt to a T56 6spd. I know I need a 2001 or newer. But this crankshaft is not stock I don't think. The 2 numbers I see on the crank are 066 and 12552215. Can anyone help me identify this? I have a Tranzilla 6spd in the car. I'm trying to bolt up to. Thanks in advance!

 

it took a whole 3 seconds to find your answer. There's plenty of threads on this here in tech as well.

 

All of the ’99 – ’00 cranks had the 12552215 casting with the wide flange. This is the only application for a crank that has a 92mm stroke and a wide flange.
