Ultima GTR with a turbo Barra inline-six

Leigh Walker is building an Ultima GTR at this company Pro Street Development in Melbourne, Victoria, Australia capable of reaching the 7’s in the quarter-mile and driving on the street. Leigh started by removing the back-half of the chassis and fabricating a custom tubular chassis with 4-link suspension. The power plant will consist of a turbocharged Ford Barra inline-six capable of 1500 horsepower. The engine will transfer power through a custom gear drive to a Powerglide two-speed transmission and through a Pro Street Development custom 9-inch rear end to a set of 15×14 wheels with 390/45/15 tires.

  1. Oh, wow, that transfer case is next level. Reminds me of gear drives tractor pullers build for their multi-engined monsters. Only “issue” I see with it is that the whole drivetrain will be a lot of weight for the otherwise featherweight Ultima.

  2. Great gear drive setup to the world’s shortest transmission. Also I love the centerlines I used to have some on my 280zx
