Quality Turbocharger & Cartridge Manufacturer

Identifying a turbocharger correctly usually involves checking several physical and informational details, because many models look very similar. Here’s a step-by-step guide you can follow:       1. Look for the ID plate or tag   Most turbos have a metal ID plate or a stamped marking on the compressor housing or the bearing housing (center section). This will usually show:   Turbo model number (e.g., GT1749V, HX35, TF035)   Part number (often from Garrett, BorgWarner, Holset, IHI, Mitsubishi, etc.) ​ OEM number (from the vehicle manufacturer)​ ​ Clean the plate if it’s dirty — numbers are often faint.       2. Check casting number   If the ID plate is missing, look for casting or embossing marks on:   Compressor housing   Turbine housing   Center housing (CHRA)   Casting numbers are not always the actual part number, but they can help cross-reference.     3. Measure the turbo   Take compressor wheel inducer/exducer diameters and turbine wheel diameters with calipers.   These measurements can narrow down possible models when cross-referencing.       4. Note the turbo type & features   Wastegate type: Internal wastegate, external wastegate, or VNT (variable nozzle turbine).   Mounting flange: T25, T3, T4, V-band, etc. ​ Compressor inlet/outlet size and turbine inlet/outlet size.     5. Cross-reference with catalogs   Use manufacturer catalogs or online turbo databases to match numbers and measurements.   For example:   Garrett: Use the Garrett Aftermarket lookup. ​ BorgWarner: Check their online catalog by serial or part number. ​ Holset: Serial number lookup on Cummins Holset site. ​   Pro tip   If you have only the vehicle info (make, model, year, engine code), you can work backwards from OEM parts catalogs to find the matching turbo model.
