Build a reliable twin turbo LS-powered Toyota Supra MKIII with the CXRacing Twin Turbo Manifold Set. Designed specifically for the 1986–1992 Toyota Supra MKIII with an LS1 or LS-based engine swap, these heavy-duty turbo manifolds feature tight-radius runners, upward-facing 3-inch V-band outlets, and integrated 46mm V-band wastegate flanges to provide excellent turbo placement while clearing factory LS engine accessories.

Developed by CXRacing in the USA, these manifolds are engineered for high-performance twin turbo applications but can also be modified for custom single turbo builds. Their compact design allows clearance around common LS accessories, including the alternator and water pump, making them an excellent starting point for custom street, drag, and competition projects.

Twin Turbo Ready Design: Engineered for LS1 and LS-based twin turbo applications with upward-facing turbo outlets for efficient turbocharger placement.

Compatible with Custom Single Turbo Builds: Manifolds can be modified for custom single turbo configurations when desired.

Heavy-Duty Stainless Steel Construction: Built with 12-gauge (2.5mm) thick-wall merge cups and reinforced construction for excellent durability under high exhaust temperatures.

3-Inch V-Band Turbo Outlet: Each manifold features a welded 3-inch V-band outlet for secure turbocharger attachment and simplified installation.

46mm V-Band Wastegate Flanges: Integrated 46mm V-band wastegate flanges provide compatibility with common external wastegates for accurate boost control.

Factory Accessory Clearance: Tight-radius runners and upward outlet design provide clearance for factory LS accessories, including the alternator and water pump.
