The clearences for the main bearings to the crank is in my workshop book for new bearings 0,024-0,042 mm and for the main bearing nr 3 in the middle 0,030-0,048mm

And the clearences for the crank to rod bearings 0,032-0,050mm

That is for a total stock engine. It´s a b16a2 and I go with stock crank, crower rods and endyn/RW 84,5mm pistons. This is my first assembly of a car engine and the dragracers that runs 1000hp volvos in sweden told me that i should increase clearences on a high output engine so they made me unshore.

Should I stay by the stock clearences or what do you guys think......
