About this category
This category groups the exchange turbochargers built for the 1.6 HDi 90 hp engine, the diesel unit found across a wide span of Peugeot and Citroen-platform vehicles rated around 90 hp. It is written for the independent garage placing a same-day order, the driver stranded with a loss of power or a limp-mode warning, the home mechanic tackling the swap personally, and the German-speaking buyer comparing exchange parts before ordering. Inside, you will find the SL Turbo and Garrett references associated with this exact motorisation, alongside their OEM equivalences and exchange-unit terms.
The range is built around the engine code first, then cross-checked against OEM and equivalent references so that a single turbocharger family covers every vehicle sharing the same 1.6 HDi 90 hp block. As the wholesaler behind this catalogue, our role is to keep the reference table current: tracking supersessions, matching actuator variants, and keeping the exchange-unit process straightforward for a workshop reordering the same part months apart.
Professional uses by trade
A turbocharger search rarely starts from a part number. It starts from a symptom, a vehicle in the bay, or a comparison between exchange references. The following usages describe how each type of buyer approaches this 1.6 HDi 90 hp range, from a scheduled workshop order to a first-time exchange-unit return.
- Le garagiste independant : Cross-checks the engine code and OEM reference against the exchange turbocharger before ordering, so the core deposit and the replacement unit arrive matched to the specific 1.6 HDi 90 hp variant on the ramp.
- Le garagiste independant : Keeps a wholesale account open across the SL Turbo and Garrett references to reorder the same exchange unit without repeating the compatibility check on a returning customer's vehicle.
- L'automobiliste depanne : Looks up the turbocharger for a car showing a sudden loss of power, dense exhaust smoke, or a limp-mode warning tied to the 1.6 HDi 90 hp engine.
- Le passionne qui fait lui-meme : Compares the CHRA, the variable geometry actuator and the OEM equivalence before ordering the exact SL Turbo or Garrett reference for a planned weekend swap.
- Le passionne qui fait lui-meme : Reads through the exchange-unit terms in advance, since the old turbocharger core has to be returned once the new part is installed by a professional.
- Der deutsche Kaeufer (DACH) : Compares generalueberholt exchange turbochargers against the OEM reference for the 1.6 HDi 90 hp engine before choosing between the listed SL Turbo and Garrett units.
Range comparison
The table below lines up every reference available for the 1.6 HDi 90 hp engine, from the SL Turbo exchange units to the Garrett-branded turbocharger, so a workshop or a home mechanic can compare the exact part before placing an order.
| Range | Use | Format |
|---|---|---|
| SL Turbo 5435 988 7000 | exchange turbocharger for 1.6 HDi 90 hp | |
| SL Turbo 49173-07508 | OEM-matched replacement turbo unit | |
| Turbo Garrett 753420-5006S | Garrett-branded exchange turbocharger | |
| SL Turbo 49373-02013 | reference for later 1.6 HDi 90 hp builds |
How to choose
Choosing among these references comes down to matching the engine code and connector layout first, then checking the exchange-unit terms and the OEM equivalence, so the part ordered today still fits the same reorder next season.
- Match the engine code and OEM reference printed on the original turbocharger before ordering, since two 1.6 HDi 90 hp vehicles can carry different connector layouts.
- Check the actuator and variable geometry mechanism fitted to the original part, as SL Turbo and Garrett references are not always interchangeable across build years.
- Confirm the exchange-unit terms in advance, since the old turbocharger has to be returned once the replacement is installed by a professional.
- Verify the connector count and wiring layout against the vehicle's wiring harness before ordering, to avoid a mismatch discovered only once the part is unpacked.
- Ask about any applicable warranty terms tied to the specific reference, since exchange turbochargers are covered differently depending on the SL Turbo or Garrett line.
- Keep the OEM reference and the equivalence table on hand when reordering the same part months later, so a returning customer's vehicle gets the identical fit.
Storage & logistics
Once an exchange turbocharger arrives, it should stay in its original packaging until the vehicle is on the ramp and ready for the swap, keeping the actuator arm and the variable geometry mechanism protected from impact. The core that comes off the vehicle needs the same care on the way back: sealed against grit and returned promptly so the exchange-unit process closes without delay. For a workshop running several 1.6 HDi 90 hp jobs in the same week, keeping SL Turbo and Garrett references separated by exact part number avoids mixing a returned core with the wrong outbound order.
Since 2026, we have kept this 1.6 HDi 90 hp reference table matched engine code by engine code, because a garage reordering the same turbocharger months later needs the exact same fit, not an approximate one.— autoKUR team
