Subienewbe Posted December 2, 2023 Share Posted December 2, 2023 I'm building my second EJ25 that I purchased from a guy who ran it out of oil. It damaged the crank and rods. New OEM rods are $400, so I ordered Scat forged rods and Nippon Racing pistons from Swap Shop Racing. The rods ended up being $80 less than OEM rods. I also ordered a stock Subaru crankshaft. When I weighed the old vs new pistons and rods, the new are 3.5 oz lighter than OEM. When I built the first EJ25 I used just the Nippon Racing pistons with stock rods. The pistons are 1 oz lighter than stock and I had no balance problems or vibrations. Has anyone installed forged rods and pistons that are lighter than stock without having the crankshaft rebalanced? I have received conflicting info, yes it needs to be balanced, no it doesn't because of the opposed design. Looking for someone that has actually done it.

Subienewbe Posted January 22 Author Share Posted January 22 So has no one installed a set of forged rods to replace the OEM rods? Link to comment Share on other sites More sharing options...
