Description

The BNR Supercars S4 Turbocharger is a performance upgrade engineered for the 1987-1988 Mazda RX7 S4 models. This turbo features a custom T04E 50 Trim compressor wheel with a 76mm exducer and a 3-inch compressor inlet. Due to its 3-inch compressor inlet, this turbocharger will not fit with stock-sized turbo inlet pipes, requiring an aftermarket intake pipe of 3.5 inches or larger. The BNR S4 is based on the OEM turbo but offers improved performance.
