BMW E36 / E46 T3/T4 Turbo Kit — M50 / M52 / S50 / S52 (323i 325i 328i)
Complete T3/T4 turbo kit for E36/E46 BMWs — 71 kits sold with a 4.9 rating, from an 11-year turbo specialist. The proven budget-boost path for M50/M52 engines that the community has been running for years.
T3/T4 turbocharger kit with supporting components for M50B25, M52B25, S50, and S52 engines. This is a serious power-adder, not a bolt-on — a proper tune plus supporting fuel and cooling mods are mandatory. Confirm your exact engine code before ordering.
Fitment: BMW 323i/325i/328i E36/E46 with M50/M52/S50/S52 engines. Confirm your year, model, trim and VIN before ordering.
Safety: A turbo kit changes how your engine breathes — a proper tune is required, along with supporting fuel and cooling modifications. Never run boost without them. Professional installation is strongly recommended, and monitor for check-engine codes after install.
Factory-direct from China: Made in China and sourced straight from the vetted factory — no middleman markup. Ships from our factory partner with tracking provided. Delivery times vary by destination.
Aftermarket part — not a genuine OEM product, and not sponsored or endorsed by the vehicle manufacturer. Fitment is verified on every order before it ships.
