There is no known block failure on a 1.6 or 1.8 markp has throw the numbers of 400+ and maybe oringing the head other than that they are real tough some have taken the 1.8's into the 500+ range the only reason the 1.6 hasn't done this is becouse people are jealouse of its character and make the 1.8 out to be better than it realy is.

Brain he is stipulating built motor but stock block. Have you ever heard of a block failure outside of the GRM person who ran 20+ degrees of timming with no retard on a boosted motor.

Throwing a rod through the block does not count as block failure it is rod failure. stock rods past 300 whp is getting into some serius think about upgrading time.

This is exceptions, not the rule. There's luck, skill, and other factors- like condition- that determine how well your engine will hold at any power level beyond stock. People blow up stock engines, people blow up lightly modified engines and some people put over 200k miles on an engine with 150% more power. In the case of DSMs, engines that made 500+ hp to the wheels on a stock shortblock were usually running some detonation resistant fuel like C16/E85 or were injecting large amounts of methanol. Most of the time an engine fails it's not due simply to power, it's bad tuning- detonation. At high power levels a lot of things have to be going right for you.

Also, nearly everyone who has a modified DSM that you talk to will have "500hp" but it's probably bullshit. Most are lucky to break 300hp, even with biggy stage eleventeen Borg-Warner turbos, AEMs and 1000cc injectors.
