KO Racing turbo kit for the MR2 and Celica Alltrac/GTFour 3SGTE engines. These Precision Turbos are similar form factor to the Garrett GT Series turbos, but with enhanced aerodynamics, and ceramic ball bearings giving these turbos unparalleled performance. Innovative design and manufacturing by Precision Turbo on their 2nd generation CEA (Competition Engineered Aerodynamics) line of compressor wheels from a solid aluminum billet has achieved an unprecedented level of performance from like sized turbos. Typical compressor wheel construction is done with a cast wheel. The advantage of meticulously machining the compressor wheel on a 5 axis CNC machine from a solid aluminum billet is that it allows for quick production of a new idea or innovation without the expensive casting molds and yields a stronger an lighter wheel. Being lighter, and with improved aerodynamic efficiency, the CEA compressor wheels spool faster and make more power than similar sized comparable turbochargers. From a price performance point of view, these are comparable or less costly than recent offerings from their contemporary competition, but performance typically will exceed the competition.

Included with the kit:

• Precision Turbo 55mm PT5555 Billet (fast spool), 58mm PT5558 Billet, or 62mm PT6262 Billet (TO4S-P compressors with 4" ported inlet -- 2.5" outlet, T3 Turbine housings)
• Full 3" downpipe with V band clamp and integrated 1.75” wastegate dump tube (with it’s own flex section) and wideband O2 Port and Plug
• Downpipe support bracket
• External wastegate:
  • Precision Turbo 40mm v-band external wastegate OR
  • Tial Sport MVS 38mm v-band external wastegate OR
  • Tial Sport MVR 44mm v-band extransl wastegate OR
  • Precision Turbo 46mm external wastegate (Click Here for more info)
• CNC machined steel manifold adapter, with integrated external wastegate port/mount.
• -4AN oil feed line
• -12AN oil return line
• Oil line adapter fittings for the block and oil pan
• Restrictor oil inlet fitting on turbo -4AN
• O-ring seal drain flange with -12AN drain fitting
• -8AN Water lines for connecting turbo to OEM water line locations.
• Water line fittings on turbo -18AN to M14x1.5 thread.
• Assorted hoses for connecting the wastegate to a manifold pressure source
• Assorted hardware (nuts, bolts, washers, gaskets, zip ties, etc.)

The adapter and down pipe are coated with the same 2000F ceramic thermal barrier coating that is on our CT26/CT20b down pipes.

*Note: These turbos are ball bearing with ceramic ball bearings and water cooling as standard options.

*Note: This is not an emissions legal part.

*Note: If ordering the Gen 1, it is necessary to purchase a 2nd gen exhaust manifold for use with this kit.

*Note: Use of heat wrap on this or any ceramic coated part will void any warranty. Heat wrap causes an over-insulation on the outside of the pipe trapping too much heat in the metal itself making it brittle. Heat wrap also tends to trap moisture against the parts which can also lead to uneven heat distribution in the piece and lead to cracking. DO NOT USE HEAT WRAP WITH THIS PRODUCT.

See the installation instructions on the Technical Articles page.
