Used Nissan Skyline Gearbox

The R32 Skyline ran from 1989 to 1994 and the R33 from 1993 to 1998, and while there is some community knowledge suggesting overlap between these generations, whether a gearbox crosses that boundary cleanly depends heavily on your specific engine code — the RB20, RB25, or RB26 in each car are the deciding factor, not the generation badge alone. Supply your engine code (found on your V5 or via a VIN check) to the breaker, who can confirm compatibility against the donor vehicle before you commit.

For a mechanical part like a gearbox, the engine code matters far more than the model year — an RB20DET, RB25DET, and RB26DETT are fundamentally different units requiring different gearboxes even if the cars share a generation or year. The engine code is stamped on the block and will also appear on your V5 or a VIN check, and it is the single most useful detail you can give a breaker when requesting a quote.

The GT-R and GTS-T are genuine Skyline trim designations carrying different engines — the GT-R uses the RB26DETT twin-turbo and the GTS-T the RB25DET — so their gearboxes are not the same unit and the trim difference here is mechanically significant, not cosmetic. Confirm your engine code with the breaker so they can source the correct box for your specific car rather than relying on trim name alone, as mid-production running changes can also affect ancillary and mounting details.

Yes, gearbox type is a core fitment requirement — an automatic and a manual gearbox are entirely different units and are not interchangeable, regardless of engine code or generation. Always specify manual or automatic when contacting a breaker, and if you are unsure which you have, it will be immediately obvious from the presence or absence of a clutch pedal.

The R34 Skyline ran from 1998 to 2002, and within a single generation parts often share strong compatibility, but mid-production ancillary and mounting changes can occur without a formal facelift announcement. Give the breaker both the donor and recipient engine codes along with both registration years and let them verify the specific units match before purchase.

All road-going Skylines sold were petrol-engined, so fuel type is not a differentiating factor for this model in practice. What does differentiate the gearboxes is the engine code — RB20, RB25, or RB26 — combined with whether the car is manual or automatic, so focus on those details when comparing listings and speaking to breakers.
