i have heard the genuine nissan clearances are to tight from factory .7thou on the rods and .9 thou mains i think is factory clearances, i was build a toght motor when my tuner pointed out he think the clearances are to tight for big HP standard is ok but for big HP he recommended 1.2 for the rods and 1.5 for the mains , he said make sure its blue printed and machined correctly by reputable machine shop, he said this in turn will creat more of an oil surface film and decrease the chances of metal to metal if used with full synthetic oil.
please correct me if anybody has been told differant this is just 1 person view point not fact
has anybody heard this also ?
