as many of us know, d's are pretty much torqueless motors. so i plan on boring this d16z6 i have laying around but my mechanic is saying that my cylinder walls arent that thick and i run the risk of blowing a hole through the block, and so i suggested sleeves and he said that you would have to bore it a little more to compensate for the sleeve and run the risk of burning up a waterjacket. im wondering if anybody has bored a z6 .5mm over or what not and if they had any problems. and if anybody knows how much i can bore it until i run the risk of blowing a hole through my block.
