looking at buying a 2.5 crank for my 2,1 stroker project but am slightly confused about the specs
as far as i was aware the 2.5 crank was nitrided then superceded by these heat treated ones like this but are not cross drilled
http://www.ebay.co.uk/itm/1211917678...d=531074677972
now i have just seen this type of crank
http://www.ebay.co.uk/itm/Subaru-Imp...item565ae564e9
so can anybody clear it up for me,which crank is the best and what years were they cross drilled?
cheers

The crank shown in your first link to the US seller is a nitrided and cross drilled crank - you can see the cross drilling on the main bearing journals.
The second link to WMS on ebay shows the later induction hardened ( not nitrided ) crank which is not cross drilled - bit of an error in the listing there.
Either way, they are both good cranks with the nitrided one's being phased out by subaru and being replaced by the induction hardened item.
