Skyline R33 GTR in GT 2 or maybe 3, the one when they introduced 'Nozzzzzz'.
Top spec everything including titanically laggy dragraccer spec turbo 1000bhp - faster than exocet in a straight line, nothing but understeer on the bends.
The warthog was tremendous in halo, turn in early and use the handbrake with the left trigger( I think) and splatter covenant sideways while your gunner mauls everything else.
