But that's kind of a strange way of looking at it, in my opinion. If you are looking at a 'replica' (actually, a lookalike...) of a GT-R, then you are not seeing the cars, are you?
The GT-R models were all about their mechanical specs: 24-valve twin cam engine, triple twin choke carbs, stainless six branch exhaust manifold with twin pipe 'shotgun' back box, electronic ignition, alloy radiator, 'quick' steering ratio, 100 litre fuel tank, 4.44:1 LSD R192 diff and 5-speed OD 'box. All that with the GT-R specific body with the different rear quarters, bucket seats, clear untinted glass, different garnish/trims etc etc. They were quite special for the time.
Taking a few bits off a lesser model and cutting the rear arches doesn't make it any kind of 89th minute substitute for The Real Thing, in my opinion. And it would be nice if a few more owners of L-gata engined (and G-gata shorties too come to that) took ownership of their particular variant's legacy and kept their surf lines intact.
