thats incorrect...there bunch of people running 420whp 500wtq on fbo without issues. There guys running 500whp on a e85 mix. Only cases where i heard of engine blowing was from bad tunes or guys treating their car like a rental car because its a lease. only issue they really have were sepertine belts coming off due to a bad pulley design on early q50 3.0tt models. The block is loosely based on the vr38 motor from the gtr, with the heads being different since its DI.
