The N13 version also came in 4WD as an option..


But as our buddy is in South Africa, the more common Langley in ZA refers to the N12 version with the E13 or E15 motor.

In AUSTRALIA, the N13 version Langley was known as the 4 door N13 Pulsar SSS. It had a Viscous LSD, and was nothing special, it missed the turbo and got a 1800cc Holden Camira engine... Damn the local content laws of the 1980s!!

In my internet travels I found the Nissan of My dreams..

Nissan R390GT1

And did you know that in 1981 Nissan and Alfa Romeo tried to co-produce the alfasud and failed!! It was based on the N13 Pulsar (Cherry) Chassis.
