We call them Bull Bars or Roo Bars over here in Australia, they have saved my bacon a few times though the years. I hit a Big red Kangaroo at 120 Kms/hr and only bent one of my spot lights, and kept going. Nothing i could do for the roo.
Im running my 1HZ turbo intercooled at 11psi atm, but i will be going up to 16psi next time I get it tuned. If i can run my 1HZ at this you should have no drama's running the 1HDT at 16psi or more.
It is an Australian car,
we only got HJ's over here 2H Diesel,
most of us run the headlight protectors here most of the roads in the outback are dirt,
And roo bars are also called Bull Bars more common
