Big Bore Engine Integrity?

Well long story hacked apart. Severe damage to cylinder 3 (B16A). Needed to be bored. Sent off the block guy calls to tell me he had to bore it .1" thats right one tenth! Im worried about the integrity of the motor. Mainly at high rpms.

82mm B16 bore is fine. the sleeves still have plenty of meat on them with a 82 mm bore. Omniman has several motors at 82mm bore on factory sleeves.

1mm oversize is ok, but you just have to have the right clearances for the pistons you are using.
