Hi. I have a couple of Subaru short blocks (case, crank, rods & pistons) & was wanting to know if they are the same short block other than displacement, meaning will heads & intakes bolt up the same on each engine? Is there a difference in a turbo engine as far as the short block? If so what is it? Is there any other #'s I should look for on the cases to determine more specifically what they are?

Thanks.
