T70 Top Mount Turbo Kit

The CXRacing T70 Top Mount Turbo Kit is engineered to convert naturally aspirated 2JZ-GE and 2JZ-GE VVT-i engines into a single turbo (NA-T) configuration. The kit features a T70 turbocharger with a T4 turbine flange, 0.70 A/R compressor housing, and 0.81 A/R turbine housing. The top mount manifold is constructed from TIG-welded T304 stainless steel with equal-length runners for optimal exhaust flow and turbo response. A 50mm external wastegate, preset to 10 PSI, is included, along with a 3-inch V-band stainless steel downpipe equipped with three O2 sensor bungs. Included hardware for a complete installation comprises an oil switch adapter, oil feed and return lines, a weld-on oil pan return bung, a turbo intake pipe, and a high-flow air filter. This kit is designed to support approximately 500 horsepower when paired with appropriate supporting modifications and professional ECU tuning. Essential supporting modifications include fuel system upgrades and engine management, with professional tuning being required before operating the vehicle under boost. Vehicle fitment includes the Lexus GS300 S140 (1993–1997, 2JZ-GE), Lexus GS300 S160 (1998–2000, 2JZ-GE VVT-i), Lexus SC300 Z30 (1992–2000, 2JZ-GE & 2JZ-GE VVT-i), and Toyota Supra MKIII MA70 (1986–1992, 2JZ-GE & 2JZ-GE VVT-i Engine Swap). However, this kit was developed using a left-hand-drive (LHD) chassis. Right-hand-drive (RHD) applications may encounter steering shaft interference, potentially requiring modification, and returns will not be accepted for RHD fitment issues. Professional installation is strongly recommended.
