Usually this is due to oil starvation. The oil pump frequently has problems as it goes over the 75k mile mark.

It's hit-and-miss. I never had an issue but I've seen others that did crack.

Many of the turbo conversions have just used the turbo hardware on the NA engine setup. You can only run 7-9 psi but it makes more than enough power.

The sohc is totally diff just same casting block,
i have both dohc and sohc
but if i get a motor that doesnt need the rpms itll live longer
feel free to correct me
The SOHC is totally another engine and really isn't anywhere near the DOHC in power potential. Basically all Mitsubishi engines are interference design; you get more power that way. As long as your timing belt is replaced every 100k miles or so it isn't an issue.
There's a handfull of people at 3si.org who have turboed their NA cars with good results. Want a V8, RWD car? Done -- just google the word "vr440".
