Dave I once saw a Westy at Speed on Tweed that had been driven over from Adelaide. It was powered by a fuel injected Nissan Skyline six. The owner said its performance was superb, both in power and torque, and its five speed box allowed relaxed (if you can ever be relaxed in a clubman type car) highway cruising. I didn't ask about the handling -- that's always a given with these cars.
Just another something to mull over ....
At the risk of being branded a heretic I'm wondering when a turbo XR6 motor will find its way into a Cobra too.
