Just curious here, assuming similar bore and stroke (turbo vs. na), I
would have thought the turbo's lower compression ratio would have made
interference less likely...
So why is the low C.R. turbo interference, while the higher C.R. na is
not...?

What am I missing here...?
cam lift? chamber shape? valve angles?

what difference causes this?
