What are the typical points of failure in the 2.3 MZR?

I broke 170 in my Del Sol but melted a bearing, and couldn't save the block. Even with an adequately sized radiator and a higher flow oil pump, the stock internals weren't able to transfer heat away fast enough. I wonder if I had a longer tranny (and thus wasn't running 9,000rpm for an extended period under mild boost) if it would've been ok, since friction and thus heat go up with the square of the rpm.

Steering was also scary as hell, I wouldn't try it again without some serious work there.
