Con rod question...

[Avendit]

On a stock 140, running a turbo it is pretty much expected that 'the con rods will give at somewhere before or around 250bhp'. Could someone clarify this for me please? Is it the rods them selves, their bearings or the thing that holds them to the piston that goes?

I'm going to put a MWR oil pan on my C2 setup, and was considering doing some of the bearings since the oil pan will be off any way. I spoke to the mechanic and he says the con bearings are easy to do once you have the pan off, and with the $/

The rods AND bearigns are both weak as hell. The bearings like to spin and the rods wad up into an S shape. I would upgrade both
