Sorry man but it makes perfect sense - a VQ running anything above standard power is more likely to go bang than an LS running standard power, and its pretty fair to say theres a lot more to go wrong with an FI setup than with NA as well, regardless of how well it was built.
You were unlucky, but relatively speaking there arent a lot of engine failures on here, which would suggest the VQ is a pretty solid lump, EJ20's, RB26 and CA18's are all much, much worse and can you guess what they all have in common?
So you reckon a built Forged engine wont outlast a stock engine when driven hard ??
