read the nisan workshop manual?
yes. if the girdle is perfectly aligned, no probs if the crank is at factory size and not an auto, and every block is differant, a thou here a thou there... i can see this being an issue. unless you supply a full range of NISSAN main bearings.
you could supply instructions on how to use an oil stone if it goes in to tight. but what if it goes in at 5 or 6 thou?
im just saying that there needs to be a way that the girdle can be adjusted.
