Race bearings like ACL use standered size bearings. If going oem than its best to measure all clearances and get the correct grade's and sizes as there is alot of choices. I would spend the little extra money and go aftermarket, but Nissan makes some very good stock bearings that shouldent needed upgraded unless going all out on your build.

I am going oem just need to know in what order they are put inplace on the crank and did not go up grade the reason is not going over 400 and stock botton end can handle that much power also got the pistons and rods ceramic coated to help with the heat load on the rods and pistons so i dont have to worry on bending brakeing a rod hopefuly. ok what i relly want to know is what order does these bearings go in.
