Hey guys, I have a obd1 B16a and its time to freshen it up so, I bought a set of B16b pistons and sent my motor to the machine shop. I am aware that the rods will need to be machined .5mm on each side near the wrist pin. But will I have to have the motor re-balanced with these pistons?

I am doing a budget rebuild here, and its not a racecar, so I wont be bouncing it off rev limiter all day... but I do want a reliable vehicle. Also, I have heard a few different answers about what the compression ratio will be with this combo.. The guy I bought them from says 11:1 and someone else said 11:6... can someone confirm this?
