perfect bore for a 6 bolt

[92_talonTSI]

As everyone knows im doing my homework on my 6 bolt build for my 2g. the motor is a complete running motor but im going to open it up to remove the balance shafts so im going to do forged rods and pistons while im in there. What would the perfect bore size be my brother and dad already took the head off and check the piston walls and all is great there. so what do you think

When the machine shop checks out the cylinders they will tell you what size overbore is needed. Don't go any bigger than you need as running a .60 overbore will yeild you NO more HP then a .20 overbore. I don't know why there is so much confusion over this.
