It carries forward the success of the prior release and adds new technology to maximize performance while holding factory fitment.\u003c\/p\u003e\u003ch3\u003eFactory-location big turbo\u003c\/h3\u003e\u003cp\u003eCTS used transient flow analysis and flow-bench testing to optimize the twin-scroll turbine housing in a GTX3582R-style configuration, while keeping stock fitment, stock location and the stock wastegate — this is not a hybrid turbocharger. Any stock-fitment exhaust downpipe, intake and charge pipe carries over. The result is a factory-location big turbo capable of a record-shattering 879whp+ with supporting mods — just transfer your factory wastegate, downpipe, intake and charge pipe during the install. Rigorously tested by Titan Motorsports on their race cars, which achieved 879whp+ with no nitrous on a stock engine block, and the optimized twin-scroll design builds boost very close to the stock turbo.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eComplete brand-new turbocharger; no core to send in or purchase\u003c\/li\u003e\n\u003cli\u003eGTX3582R-style Gen2 ceramic dual ball-bearing CHRA\u003c\/li\u003e\n\u003cli\u003eBillet 11-blade compressor wheel\u003c\/li\u003e\n\u003cli\u003eProprietary stainless steel turbine housing, flow-matched to the turbocharger\u003c\/li\u003e\n\u003cli\u003eVSR balanced to exceed OE tolerances\u003c\/li\u003e\n\u003cli\u003e4-inch turbo inlet included\u003c\/li\u003e\n\u003cli\u003eOil and water fittings included\u003c\/li\u003e\n\u003cli\u003eCompatible with factory installation hardware (not included)\u003c\/li\u003e\n\u003cli\u003eCompatible with factory wastegate actuator (use your original, not included)\u003c\/li\u003e\n\u003cli\u003eCompatible with all 6-port B58TU engines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e2021-present A91 Toyota Supra with 6-port exhaust manifold\u003c\/li\u003e\n\u003cli\u003e2019-present BMW G20 M340i\u003c\/li\u003e\n\u003cli\u003e2019-present BMW Z4 M40i\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInstallation and tuning must be performed by a qualified professional.\u003c\/p\u003e\u003cp\u003eShips from our Vancouver shop — KORE SPEED is proudly Canadian-owned, with no surprise cross-border duties for Canadian buyers.
