Well, regarding turbo issue it's been many threads on MLR, interesting tho is compressor wheel being so fragile that can "explode", similar flow design as old 78-series TD05 from Evo 9.
As for engine block and heads, it's more related to Lancer n/a with 4B10 engine, quite lot of those I had read on Mitsumaniaki, usually as result of overheating issues.
In one instance, one of major Mitsi dealer stepped in and explain that 4B1x engines are very sensitive on oil grade used, which may lead to malfunction of oil pump (too low oil pressure) and as result to insufficient lubrication of timing chain and potential bottom end fails.
Oh... forgot to mention... electronic throttle body often suffers from electic glitch in SST model putting car in a limp mode.
Most of Lancers n/a chassis I've seen being at Polish Mitsi members annual meet actually are in as bad condition as our beloved 8g Galants (wheel arches even worse), just hidden enough under all plastic trims all around.
To summarize, everyone has his individual and personal opinion and view. Personally I like Evo X look and maybe if I had funds there back in time I might jump and bought one, but now I'm afraid Evo 10th generation is a massive NO for me, would rather stick to old good E9.
Well, that's just the brief summary.
