I'd rather see a non-cross-drilled crank where the oil is picked up from a central oiling bore that runs the length of the crank, or something like that.
bboy,

bumping an old thread for pics of the drilling modification....

I'm curious to see what oil pressure you are seeing with the 12mm.
stock crank or extra cross-drilled variety?

still waiting on a few bits to come in before the motor goes in the car...
I'm really wondering whether to use 1 or 2 shims...I'll probably just run 2 and see what the pressure is.
Better safe than sorry.
