This is the last of the six cylinder engines produce by Ford Australia, Though it can trace ancestry back to the original 144 cu inch engine of 1960, I believe the only thing common to both is the bore centres.
In turbo form as on this car, it was rated just short of 400hp. This car runs at 12psi boost and possibly around 420 - 450hp at present.
The fuel system uses the original tanks with a low pressure pump feeding a fuel chamber in which the high pressure pump is located.
The transmission is the ZF 4 speed auto that came with the earlier Barra engine cars. There is no build thread. The creator of this car did a Barra non turbo conversion of another series1 XJ6 prior to building this car. That car successfully competed in an outback charity rally, finishing the course despite early skepticism.
The engine and transmission keep the original ECU. It is mounted where the battery used to be. The new tacho is fed by this ECU - the original will not work without a single coil. The speedo works off GPS.
Not sure of the wheel type, yes, they do look similar to minilites. Tyres are 225/60 16 on 7" width.,
