Nissan has expanded its Nismo Heritage Parts program to now offer factory parts to owners of the R33 and R34 Skyline GT-R models.

The program was launched last year with a catalog of almost 80 parts for the R32 Skyline GT-R. It was well received and many owners of Nissan performance vehicles asked the Japanese carmaker to expand it.

The revised program will see new exterior, powertrain, electrical, and various mechanical components made for the R33 and R34 models. The range of R32 parts has also grown and now includes hard-to-find components such as new weather stripping and power window switches.

In total, the Nismo Heritage Parts program now includes roughly 160 available parts for the R32, R33 and R34 models. The program is a joint project between Nissan, Nissan Motor Sports, Autech Japan, and a selection of suppliers.

It is especially useful for owners of the R33 and R34 looking to maintain their vehicles with factory parts rather than being forced to purchase used components or turning to aftermarket parts. This will prove especially important for R34 owners as, in recent years, limited-edition examples of the sports car have soared in value, with models like the R34 GT-R Nismo Z-Tune routinely demanding more than $500,000 nowadays.
