do what this guy did. He runs in the 12's with a N/A straight 6 and its totally streetable. If you are going to make a smallblock las light as a L6, you'll need a whole hell of a lot more cash for parts than you would to make the 6 as fast as the 8. JWT does offer a 280zx program.
small block swap kit is gonna be $1000, plus the small block and build itself, another $1000, then a custom driveshaft, another $300, and then if yhou want to make it light as well, your gonna need aluminum heads and waterpump, at least another $1000.
get a 280zx turbo drivetrain and computer, $500, n/a transmission, about $100. then a T3/TO4E hybrid for about $300, some 370cc injectors, about $150, and a starion intercooler, about $50. figure about $300 for exhaust and intercooler piping, and your done! all for uder $1500, and it BOLTS IN. the set-up would be good for about 350RWHP, and still get decent mileage to boot.
