My first 510 was a 1971 4-door. I installed a turbocharged 2.8-liter motor, Turbo Toms high-output turbo system, and a 3-1/2" exhaust. I made a full roll cage with extra frame bracing. Carrera coil-over suspension with custom anti-roll bars was utilized on the front and the rear. Also a slotted rear subframe with enlarged exhaust hole, adjustable tension rods, 15-inch Panasport wheels and 280ZX brakes.
This '72 2-door 510 had a Chevy V6 with twin turbos, twin intercoolers, and programmable engine management system with sequential EFI and crank-triggered direct ignition system. The engine was fully built for high-boost operation. It had a rock-crusher gearbox, an R180 3.90:1 limited slip, huge four wheel vented brakes, adjustable coil-over suspension, adjustable anti-roll bars, sticky Yokohama tires, and much more. What a blast this car was to drive!
