Guys,
I'm after a bit of technical information regarding conrod bolts. I am sourcing some parts for an engine rebuild at the moment and there are two different size conrod bolts that I can use (there might even be more than two). The two sizes are 9.5mm and 8mm.
Can somebody explain what the difference is all about? Is one size necessarily stronger than the other? For reference, they are both ARP 2000 conrod bolts (200,000psi rating or whatever it is).
Anyway, just keen to get some technical info about them, apparently most people use the 8mm rod bolts, but the place that makes the particular conrods I'm looking at purchasing sells and recommends 9.5mm conrod bolts with their rods.

That's what I was thinking, but I would've thought different sized conrod bolts wouldn't change much between GSR/EVO/VR4. I could be wrong, these measurements are actually for a GSR conrod setup, and apparently both sizes work.
The difference I'm lead to believe is the thread diameter, however, how can a conrod take an 8mm bolt as well as a 9.5mm bolt?
