Not exactly sure what people are after and I don't want to spam the Nissan/NISMO staff and make them think I'm only hunting for prices but not buying. But for the sake of ideas, RRP is based of average of Australian Nissan dealers:
R34 GT-T M/T NISMO Cluster - $590 (RRP $800)
RB25 Engine Fans - $130 (RRP $160)
RB25DET Speedo Sensors - $90 (RRP $160)
R32 Speedo cables - $95 (RRP $190)
This GB will be good for mechanical, interior & body parts. Things like seals, gaskets, grommets or hoses won't save much, but should be able to get.
