I’m doing a b20v build I had a ? I got a b20 block from a friend for free but had a spun bearing and one rods is bad and that spot on crank is bad but he told me it can be fix and machines cause I still need to do it when I do mt new rods and piston is that true

 

It can be fixed, but the cost to do so properly is likely higher than buying a used or remanufactured crankshaft.

 

So true in buying nippon piston and rods and they have a brand new standard size crank to match my kit for 210 brand new crank
