I'm in the process of rebuilding a redtop SR20DET before it's swapped into my S14. I plan on making a build thread soon whenever I make more progress. The motor actually looks great internally I'm just rebuilding this for peace of mind. I popped the bearings to take a look at them and they still look like new. I could reuse them but since new bearings are <$100 I figure why not replace them, right?
When buying OEM bearings you have a choice of different grades. I see the markings on my crank and know which OEM's I need to buy but would rather get Clevite 77's since they're coated and arguably better? From searching around I see all aftermarket bearings are a one size fit all, no grade, just different in aspect of STD, oversize, etc..
If I were to buy Clevite 77 STD size bearings, will the crank need to be machined since they are not available in various grades? If I plastigauge the Clevite 77 bearings will they fall into OEM specifications? Since my crank is still good I would rather not have to machine it. IF aftermarket bearings require machining because of the lack of grades I will not run them and buy OEMs.
