Isuzu Turbos For Sale

It depends on the engine and condition. The 2.5 TD (4JA1) is the most affordable at roughly R4,750 – R4,995, and it is well supported with used pull-offs. The flagship 3.0 D-Teq / DDi (4JJ1) spans a wide band from around R7,497 for a tested used unit up to about R14,995 for new aftermarket. The older 3.0 TD (4JH1-TC / 4JX1) and the newest 1.9 Ddi (RZ4E) are best sourced on a quote — the older engine has thinner used stock and the 1.9 is too new to have a settled used price. Submit one quote request and compare verified suppliers for your exact model.

The most common cause on the variable-nozzle (VNT) units — the 3.0 D-Teq / DDi (4JJ1) and the newer 1.9 Ddi VGT — is the VNT vanes and actuator sticking with carbon and soot. That shows up as power loss, going into limp mode, a whistling or whining noise, or black smoke. Across all the diesels, oil starvation from a blocked feed pipe or a stretched service interval is another common killer. Sometimes it is just the actuator or a clean and recon rather than a whole turbo, and worn injectors or a blocked DPF can mimic the same symptoms, so it is worth having it properly diagnosed before buying a full unit.

The 4JJ1 3.0 D-Teq / DDi uses an IHI RHV5/RHF5 variable-nozzle turbo (part 8980115293) — it is the flagship SA bakkie turbo and the highest-demand Isuzu unit, sitting at a higher ticket. The 4JA1 2.5 TD uses a simpler IHI RHF4/RHF5 (part 8972402101), which is the cheaper, high-volume second choice and well supported with used pull-offs. Give your model, year and engine when you request a quote so suppliers match the correct turbo, and confirm the exact part number by VIN.

All three are common in SA. A used pull-off is the cheapest and fine if it has been tested and comes with some warranty. A reconditioned or exchange unit (you surrender your old core) is usually quote-only and carries a longer warranty. New aftermarket or OEM-grade units cost the most but are brand new. On the D-Teq and 1.9 Ddi VNT units especially, check whether the electronic actuator is included and calibrated. Watch out for cheap "CHRA core" listings — a bare centre cartridge is not a complete turbo.

Confirm it by VIN or engine number — Isuzu uses more than one part number and housing across the range. The 3.0 D-Teq (4JJ1) is IHI RHV5/RHF5 (8980115293), the 2.5 TD (4JA1) is IHI RHF4/RHF5 (8972402101), the older 3.0 TD splits into 4JH1-TC and 4JX1 (RHF5 VIEK), and the newest 1.9 Ddi (RZ4E) is an IHI VGT. Tell us your model, year and engine (and ideally your VIN) when you request a quote and verified suppliers will confirm the exact unit before you commit.

It varies by supplier. Tested used units typically carry a 30–90 day warranty; reconditioned and new aftermarket units usually 6–12 months. Because a failed turbo can be caused by oil-supply or DPF issues, a good supplier will also advise on fitting the correct oil feed/return and priming the unit. Always get the warranty terms in writing and confirm whether fitment at a qualified workshop is required.
