from the site "A car with as much power and performance as this shouldn't be stuck with headlamps that use stone age technology. This retrofit was done to a 1990 Nissan 300 ZX with OEM projector based headlamps. This retrofit used Bosch projectors, Hella ballast, and Philips 4100k D2S bulbs. The Bosch projector was chosen for its small size which matched the stock projector's size almost exactly. The end result is a headlamp thats virtually indistinguishable from the stock headlamp." 900 bucks from those guys.
