TURBO TURBOCHARGER UPGRADE 400+HP FIT 2000-05 VOLKSWAGEN JETTA/GOLF 1.8T K04-001

Turbo Turbocharger for Volkswagen Jetta and Golf 1.8T

This turbo turbocharger for Volkswagen Jetta and Golf 1.8T delivers 400+HP of boosted airflow, giving the 1.8T engine the gain in power its factory turbo leaves on the table, and it cross-references the K04-001 upgrade specification.

Overview

This turbo turbocharger is a bolt-on replacement built for the 1.8T engine in the Volkswagen Jetta and Golf, engineered to push output past 400HP when paired with supporting fuel and tuning work. It swaps in for the factory turbo on 2000-05 models and brings the spool and top-end charge the K04-001 spec is known for. It suits owners who want meaningful power from the 1.8T without rebuilding the entire induction setup.

Built For Performance

• 400+HP target output when matched with fuel, intercooling, and tuning support
• K04-001 specification compressor and turbine sizing for stronger top-end flow
• Direct replacement footprint for the 2000-05 1.8T engine bay
• Construction rated for sustained boost pressure and heat cycling
• Compatible with standard turbo oil feed and coolant line routing on the 1.8T

Fits These Machines

• for Volkswagen Jetta 1.8T 2000-2005
• for Volkswagen Golf 1.8T 2000-2005

On-The-Job Use

• Street builds chasing a serious power bump on the 1.8T
• Track and autocross cars needing stronger mid-range and top-end charge
• Replacing a failed or worn factory turbo with an upgrade-spec unit
• Project cars running supporting fuel, intercooler, and ECU work

Specs At A Glance

Good To Know

Q: Will this turbo make 400HP on a stock 1.8T? A: The 400+HP figure assumes supporting fuel delivery, intercooling, and a proper tune, not a stock ECU. Plan your supporting parts before install.

Q: Does this bolt directly to the factory exhaust manifold? A: It is built as a direct replacement for the 2000-05 1.8T turbo footprint. Confirm your specific manifold and downpipe flange before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
