Technoman, save your money and do it right, when you start gerry rigging stuff is when you start breaking stuff.
BinaryVertigo: No, we got the rods from Crower, withing specs to allow for a certain size of main bearing, which was dependent on the crank. In other words theres no machining required, and the fact that nissan makes like 15 different sizes of main bearings for the Ka24DE helps out alot too. As far as the pistons go, same thing, however, we will be honing the cylinders to allows the rings to have a good surface to sit on. As far as your crank, I dont know the situation on it, mine was out of a rebuilt engine with 50k original miles on it so it was extremely in spec. Always be sure to get it magnafluxed to make sure you dont have any cracks in it or anything. It would probably be wise to have a machine shop do it for you, in case there is more machine work to be done.
