This is a Nissan RB25DET engine for sale in fairly used condition: a complete 2.5 litre turbocharged inline six, taken from a donor car, inspected, compression-tested and ready to ship worldwide. It’s the engine for the Skyline R33 GTS-25t, the R34 GT-T (NEO), the Laurel and the turbo Stagea.
We confirm whether you need the standard engine or the NEO, check the series, and send photos of the actual engine before you pay.

Standard, Series 2 or NEO?
The standard RB25DET arrived in 1993, with Series 2 updates around 1995 that changed the engine computer and ignition. The NEO came in 1998 with a revised head, different cam timing control, a revised turbo and more torque. Electronics differ between all three. If you’re keeping your car’s existing computer, match the version. Tell us what you have and we’ll match the right Nissan RB25DET engine for sale.
Stock, Tuned or Tired?
Many RB25DETs have been boosted and driven hard. We check for aftermarket parts, signs of high boost, and the condition of the turbo’s compressor wheel, and tell you what we find. Healthy stock engines suit road cars; solid cores suit builds.
Fairly Used, Reconditioned or Rebuilt?
The price here is for a fairly used, tested engine. We can also quote a reconditioned unit with a new timing belt, gaskets and seals, or a full rebuild ready for a bigger turbo. Tell us your plans and we’ll recommend the Nissan RB25DET engine for sale that suits them.
How We Test It
- Compression test on all six cylinders.
- Leak-down check where possible.
- Block and head checked for cracks, leaks and overheating.
- Turbo checked for play, leaks and compressor wheel damage.
- Oil checked for coolant, fuel or metal.
- Photos and, on request, video sent to you.
Every Nissan RB25DET engine for sale on our site has passed these checks.
Signs It’s Time to Replace Yours
- Low or uneven compression across the six cylinders
- Bent valves after a timing belt failure
- A spun bearing
- Cracked ring lands from a bad tune
Old coil packs, a boost leak, a sticking cam timing solenoid or a tired turbo can often be fixed instead. We’ll tell you if that’s the better route.
Swapping an RB25DET?
The RB25DET is a favourite swap engine. Plan for engine bay space (it’s a long straight six), the matching gearbox or an adapter, the donor loom and computer or an aftermarket ECU, a bigger radiator and a fuel system that can keep up. A front clip saves time. Ask us for a Nissan RB25DET engine for sale with the loom, computer and gearbox from the same car.
What a Healthy Used RB25DET Looks Like
- All six cylinders close on compression
- Clean oil with no milky colour or metal
- A turbo with little shaft play and an undamaged compressor wheel
- Coil packs without cracks
- No heavy oil in the intercooler pipes
Where Our RB25DETs Come From
Most of our RB25DETs come from Japanese-market donor cars. Plenty of Japanese cars come off the road because of inspection costs rather than worn engines, so there’s a steady supply of decent cores. We still test every one. Each Nissan RB25DET engine for sale is matched to the car it came from, so you know whether you’re getting an R33 engine, an R34 NEO, or a Laurel or Stagea unit, which matters for the electronics.
Fitment Details We Need
Send us these and we’ll confirm the right Nissan RB25DET engine for sale:

- Manual or automatic
- Whether you need the loom, computer or gearbox
Fitting Tips
- Fit a new timing belt, tensioner and idler.
