Hello guys. Sorry im a newb. This is my 1st STI engine rebuild and I still have a lot to learn. Anyway I bought a 2011 STI with spun rod bearing. I bought a set of forged connecting rods to replace the stock rods which 1 of the rod was bad due to the bearing spun in it. however the forged rods that i bought would not fit the stock piston. On the stock rod it has a taper at the end of the rod to be able to slide in the piston pin hole. However on the forged rods there are no taper so I cant fit it into the stock pistons. Are the forged rods have to fit with aftermarket forged pistons?
