R33 Drive Belt Differences

[Mick]

hey the original nissan belts on my r33 are

ALT 4pk850

AC 4pk910

PS 3pk845

but while looking for a replacement set on ebay it has slightly different ones that are a lil longer by 5 to 10mm

ALT 4pk855

AC 4pk915

PS 3pk855

and it seems that most people that are selling Bosch sets are saying these part numbers as well so im wondering why different sellers are all saying these are for my car when my original ones are different, is it that bosch ones are a lil smaller than they say they are, or that the nissan ones are a lil bigger than they say they are or is it that its better to get slightly bigger ones for some reason, im confused and i know its only slight size differences but its very confusing still

Check the feedback on eBay. If they don't fit people would mention that!

Buy the belt set off Kudos Motorsport. I guarantee they fit

Those will work fine, I suggest getting 835 for the power steering or you will need to wind the tension bolt all the way out.
