KO Racing turbo kit for the MR2 and Celica Alltrac/GTFour 3SGTE engines. The Street Brawler G Series Turbo kit was developed as an expansion of the already widely successful versions that have been making and breaking records since 2003. The latest technology from Garrett is available to you in the form of these new turbos with power ratings up to 600+ (at the flywheel). The kit includes a manifold adapter, which is CNC machined from a solid steel billet and bolts to the stock manifold to retain OEM reliability. The other components include a full 3" mandrel bend down pipe with integrated 1.75" diameter wastegate dump tube, with it's own flex section, a 38-40mm external wastegate, all lines, gaskets, and mounting hardware needed to install the kit. These turbos are dual ball bearing, feature the latest billet wheel technology, and are water cooled standard.

What's included:

• Full 3" downpipe with V band clamp and integrated 1.75” wastegate dump tube (with it’s own flex section)
• Wideband O2 Port and Plug top and bottom on the downpipe
• Downpipe support bracket
• CNC machined steel manifold adapter, with integrated external wastegate port/mount.

*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: If ordering the Gen 4/5, it is necessary to purchase a 3rd 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 (under Street Brawler).
