    minimum bearing clearances for rebuilding 4-tec engine?

    I've been searching all over and I have the factory service manual. But all it says is the maximum service limit clearance for rebuilding the engine. I have a 06 RXP that I bought with a blown supercharger. I ended up having to tear it all apart and replace all the bearings and oil pumps and housings. I crankshaft and everything else are good and I had the crank micropolished. I ordered the bearing sets from SBT so I have a few sets to play around with. Should I just put the stock spec ones in and plastigauge test them and go from there?

    I would run .002 inch minimum. As a general rule you want to have approximately .001 inch of bearing clearance for every inch of journal diameter. So for a 1.966 inch journal, .002 would be a good bearing clearance. Manual states .0028 max
