This kit is designed for Acura RSX and Honda Civic Si with K20 engines (model years RSX 2002–2006 and Civic Si 2002–2005). The T3/T4 flange and universal piping also make it suitable for many 4–6 cylinder swaps, but some vehicles or engine swaps may require custom mounting, brackets, or plumbing.
The package includes: T3/T4 turbocharger, turbo manifold, intercooler, intercooler piping, downpipe flange, 35/38mm external wastegate, Type-S blow-off valve, boost controller, turbo oil feed and return braided lines, oil pump, 255 LPH fuel pump, adjustable fuel pressure regulator, turbo timer, and hardware listed in the product description.
The turbo can support boost roughly from 0.5–1.5 bar (about 7–21 psi). The specified optimal operating range is around 7.5–14.5 psi for street use, and the unit has been quoted to support 400+ HP in certain B-series swap applications. Actual safe power depends on engine internals, fueling, and tuning.
Key specs: compressor inlet 72 mm, compressor outlet 53 mm, compressor trim 48.1, compressor inducer 52.7 mm, compressor exducer 76 mm; turbine inducer 64.8 mm, turbine exducer 55.8 mm, turbine trim 74.2, turbine A/R 0.63, compressor A/R 0.5. Bearing type is wet float bearing. Exhaust inlet uses a T3/T4 4-bolt flange.
The intercooler core is a tube-and-fin design with a core size around 24" x 12" x 3.0" and full size roughly 30.5" x 12" x 3.0". It uses 2.5" inlet/outlets and is stated to support up to approximately 350 HP for efficient cooling in this small size.
Yes. The kit includes stainless steel braided turbo oil feed and return lines and an oil pump to ensure proper lubrication and oil circulation between the turbo and the engine oil pan.
The kit includes a 255 LPH electric fuel pump and an adjustable fuel pressure regulator. The regulator is listed as adjustable (specs in the listing state up to 140 PSI), but fuel pressure should be set and tuned to match your application and injector capability.
Included are a CNC billet Type-S/RS-style blow-off valve compatible with 2.5" piping, a 35/38 mm external wastegate, and a manual turbo boost controller capable of up to 30 psi adjustment. Final boost control should be tuned with a proper boost controller and wastegate setup.
Yes. Proper ECU tuning (or a stand-alone engine management solution) is required to adjust air/fuel ratios, ignition timing, and boost control. Tuning is essential for reliability, drivability, and to prevent engine damage.
This is a comprehensive but universal-style kit—some fabrication or vehicle-specific brackets, exhaust piping, gaskets, sensors (MAP, O2, boost solenoid), engine management, and wiring may be required. Professional installation is recommended if you are not experienced with turbo systems.
For reliability and drivability, recommended supporting mods include upgraded fuel injectors (as required for target power), intake and exhaust upgrades, stronger engine internals for high horsepower goals, an appropriate ECU tune, oil and cooling system upgrades, and an external catch can if needed.
Regular oil changes with high-quality synthetic oil, allowing proper warm-up and cool-down periods (idle briefly before shutdown) to protect the turbo, periodic inspection of oil lines and clamps, and checking boost and air/fuel ratios after installation are recommended.
Many turbo swap kits are not emissions certified and may not be legal for street use in some regions. Legality depends on local laws and emissions regulations—check local rules before installation. Catalytic converter and emissions equipment requirements vary by jurisdiction.
The product listing states a 2-year warranty. Check the seller’s warranty terms for details, such as exclusions, required maintenance, and return procedures, and contact the seller for installation support or technical questions.
