ask big truck driver... he was rocking the cr/vtec to 9k rpms... managed to crack all 4 sleeves.
Damn that's insane both cracking all sleeves and revving that motor up that high. I wouldn't mind buying a used B16 or B18c shortblock but, good luck finding a good one for a decent price. Secondly i already got burned on my current motor by someone on this board, so im a little leary about buying again. I bought the complete swap got it in my car only to find out that the motor knocked upon the first time starting it up.
