Buying a Used Z33 350Z 6-Speed Gearbox from Japan: Prices (2026)

A used, complete Nissan Z33 (350Z, sold in Japan as the Fairlady Z) six-speed gearbox sold for a median ¥90,000 (about $563) on Yahoo! Auctions, across 7 sales in the 120 days to 1 October 2026, with prices from ¥71,000 to ¥211,000. Those figures come from the TSUISO parts price index row re-read on 3 October 2026, and the adaptor and shipping details below were checked on the makers’ and Japan Post’s own pages on 11 October 2026. Getting one overseas means draining it, crating it and staying under the EMS limit of 30 kg (20 kg to Australia), or moving it as freight.

Dollar figures use ¥160 to $1. Sold prices come from the JDM drift parts price index (Yahoo! Auctions closed sales, complete gearboxes only).

What did the 7 Z33 gearboxes actually sell for?

Seven sales is a tight sample, so here is every one of them, read from the listing titles:

The split is clear. The 4 bare gearboxes sold for ¥71,000 to ¥90,000. The 3 listings above ¥130,000 were assemblies (ASSY) that bundle the propeller shaft, and the top one adds an aftermarket ATS clutch. If you only need the gearbox, the bare units are the row to price against.

For the rest of the swap budget, the used engine price guide uses the same index, and the R154 buying guide covers the Toyota five-speed that the Z33 box is usually compared against.

Which codes are you buying, and what do the adaptor makers say?

The Z33 six-speed is listed by adaptor makers under its revision codes. We don’t confirm fitment ourselves. Here is what Collins Adapters states on its own product pages:

Collins’ JZ instructions describe the 350Z CD001 to CD009 family as having an external slave cylinder and the 370Z JK40 units as having an internal concentric slave, with different bolt counts for each. We did not find a Nissan page that maps each CD code to a model year (checked 11 October 2026), and the gearbox weight is not stated by the maker. One sold title above reads “CD5” for a late-model unit. That is the seller’s text, so read the code stamped on the case itself.

How do the price tiers stack up?

How does a Z33 gearbox get out of Japan?

The gearbox and diff shipping guide covers the rules in full. In short, a gearbox is not banned by name, but Japan Post caps EMS at 30 kg (20 kg to Australia, with a 1.05 m length limit to Australia and Germany), and motor oil is accepted in international mail only in a wooden crate or a box boarded top and bottom and banded. Even Collins drains the fluid and builds an internal wooden crate before it ships a new unit inside the US. A propeller shaft from an ASSY listing adds length, so measure it before you assume the postal route.

Where do overseas Z33 gearbox buys get stuck?

The stuck step is the seller who will not post it to you, and the shift you cannot feel from abroad. The cheapest unit in the sample, ¥71,000 on 18 April 2026, was listed 個人宅配送不可: no delivery to private homes, hand-over near the seller only. A proxy has no one to send to the door. Even when a seller ships, “fully working” and “good” are words. Second-to-third synchro grind, input shaft play and what the oil looks like coming out do not show in a photo.

What should you check before you bid?
