CTS Turbo EA113 2.0T BOSS500 Turbo Kit (MK5 GTI/Jetta, MK6 Golf R, 8P Audi A3/S3)

CTS Turbo's BOSS500 brings the BOSS platform to FSI (timing-belt) owners — a modular Bolt-On Speed Solution good for upwards of 600hp with long-term reliability.

In-house CHRA and housing

The FSI kit uses CTS's own CHRA in a proprietary exhaust housing, cast and machined in-house to clear any exhaust downpipe with a scroll area targeting roughly 0.63 A/R. The result is excellent boost response with no restriction. Custom oil and water lines complete the kit for simple install, tuning and operation, with proprietary molded silicone hoses linking the turbo to your outlet pipe and intake.
