your one-stop shop for
Napier turbochargers

TSI provides parts, repairs, upgrades, testing and exchange services for Napier turbochargers.  For any turbocharger that comes to our shop for repairs or upgrades, we do a complete disassembly, cleaning, and inspection. We keep a record including pictures of each turbocharger we repair so we have a complete life history of your turbocharger. For all upgrades and new turbochargers, we do a run test on our closed loop test stand and provide a report for your records.

TSI supports the NA250/255/295/297/355 series turbochargers found on CAT Diesel and Ingersoll Rand engines.
