Low mileage proves little on a 2022-onwards engine; documentation proves everything. A used T3Y4 should come with the donor's Reg, the coded specification for that derivative, and confirmation of the hybrid hardware included. Reviewed records put the engine in the CX-60 254 AWD (2022) at 254 PS / 550 Nm.

Used T3Y4 Engines (3.3 e-Skyactiv D) — Buying Near-New Without Buying Trouble
A used T3Y4 engine is a different proposition from most used diesels: these are recent units — often low-mileage — built around mild-hybrid electronics. That makes provenance and electronic evidence the deciding factors, not the mileage number. Here's how CX-60 owners should buy one.

What should a used T3Y4 donor show?
A complete 3.3-litre e-Skyactiv D with the electronic hardware accounted for — starter-generator, battery system, sensors — and records that tie the unit to a real donor vehicle, not a pallet.
Which Mazda takes a used T3Y4?
The verified application is the CX-60 254 AWD (2022); other versions and models need separate verification. Match the code and configuration to your car before anything else.
Vehicle context: CX-60 hub; code context: T3Y4 guide.
| Model | Generation / body | Engine | Output | Evidence status |
|---|---|---|---|---|
| Mazda CX-60 | 254 AWD (2022 cited) | Diesel | 254 PS / 550 Nm | Reviewed application record — not established for CX-80 |
| Other derivatives | — | — | — | Still to confirm — check the code against your Reg and Mazda EPC |
What should you check on a used T3Y4?
Theme records flag DPF/regeneration and AdBlue/NOx attention — plus, on any used unit, the electronics.
Family context: engine directory.
Donor identity: Reg, mileage and records.
Holiday hardware: what's included, what transfers.
Test evidence: running/scan results for both mechanical and hybrid systems.
Storage: how it's been kept since removal.
Used, reconditioned or supply-and-fit — what suits a T3Y4?
A genuine low-mileage used unit can be excellent value — with provenance; reconditioned buys documented internals and integration; supply-and-fit suits hybrid-capable workshops.

How do you vet a used T3Y4 before buying?

Used T3Y4 questions
Is low mileage enough on a 2022 engine?
No — on a young engine, documented provenance matters more. A low-mileage unit with no records is still an unknown.
What hybrid parts should come with it?
Ask exactly what's included: starter-generator, battery system, sensors and modules. The written schedule should say what transfers from your car.
Can I fit a T3Y4 to a CX-80?
No fitment is established for the CX-80 — the verified application is the CX-60 254 AWD. Don't buy on a maybe.
What tests should a used T3Y4 pass?
Mechanical running/compression evidence and electronic scans — both, not either. Get the results in writing.
