Thats a bit of a worry if a 5S crank with its original big-end journal size cracks like that.
The 5S cranks machined down to 3S size would be a decent amount weaker.
could be a bad crank, rare. how does the bearings & pin look
crower will make a custom crank for some $$$$ but if there are stock 5sfe cranks making+ hp for years in drag cars, not money well spent
The bearing looks normal. I never looked at the wrist pin. Gave my rod and piston still together to the machine shop. I'll ask him to look at it and take photos.
Yeah I've been doing some thinking and going back and forth between the custom crank and stock. Starting to lean back to the stock one. I questioned the MR-2 board and only got one response that someone had crack their crank also.
