The new K03/K04 "Eliminator" series of turbos offers the VW/Audi driver new choices for replacement turbos that will do a lot more than just "replace" the failure prone stock turbos from KKK.

GT2X - Stock appearance, not stock power. Capable of (290hp)

The newly developed "GT2X" bolt-on turbo unit makes for an exceptional replacement for both the K03 and K04 turbo customer who likes their turbo in the stock location utilizing the stock exhaust manifold. This turbo is also for the customer that does not want to miss out on the low end "grunt" or torque of the stock turbo. However with the GT2X, expect to be pleasantly surprised by the flatness of the torque band and linear power delivery all the way to redline. Unlike the K03/K04 series, the GT2X has been designed to allow for a full power band on the 1.8T engine without choking up after 5000 rpm due to excessive backpressure at the turbine (a common problem even for customers that have upgraded from a K03 to K04).

What makes up the GT2X is a combination of a highly efficient small frame Garrett turbo cartridge (consisting of a highly optimized wheel combination that is fully assembled and high speed balanced from the Garrett factory. The result is nothing short of spectacular - an awesome breathing turbo and engine combination that likes to rev! In terms of performance, the GT2X (even though a non-ball bearing turbo) has the ability to start building boost right off idle speeds with more than 200 ft/lb of torque available from 2500 rpm all the way to redline, giving it the feeling of a powerful V8. This turbo, with its modern GT wheel aerodynamics, has the unique ability to make boost "now" and not make any qualms about holding the boost to redline.

Have no fear about this turbo going KKKaboom. The GT2X turbo shaft is at least 25% larger than any K03/K04 turbo and since this turbo can provide peak hp without going outside of its peak efficiency range, it will not be forced to run at the reliability limits. This turbo happily makes a reliable 275 crank hp on pump gas and close to 300 crank hp on high octane.

GTRS - Big power, small package, still stock appearing. (Capable of 350hp) recommended injector upgrade 550cc

For those 1.8T customers that have "GT28RS" envy but simply do not want to turn their engine bay upside down to run the "disco potato", the solution is here. The GTRS is a bolt-on solution using the ultra-efficient and much larger than stock, GT28RS ball bearing turbo popular for making 350 hp. Tasked with the mission to make the GT28RS bolt in the stock location utilizing all stock components (i.e. manifold, down-pipe, inlet pipe, etc.) Contrary to popular speculation, the stock manifold does perform quite well and when coupled with the right turbo combination, the power can exceed expectations. A lot of the deficiencies in the stock turbo system can be attributed to the low flowing design of the stock turbo and turbine housing itself! The OEM's integration of the original turbo into the 1.8T engine allowed too little flow potential in the stock turbine housing simply to promote exhaust velocity for low end flow. The result is too much backpressure and there lies the cause of the "choking" in the system, causing the lack of power in the high rev range.

"More power and even sooner than expected!"

And the rest is butter! The GTRS even in the bolt-on combination has no problem extracting close to 350 Crank hp @ 22 psi of boost on the otherwise stock engine.

The Eliminator series, just like any other turbo will respond well to "enhancement" modifications. Restrictive catalytic converters and small down-pipes can rob the turbo of its potential. Just like any other turbo, upgrading the exhaust flow and relieving backpressure before and after the exhaust system will result in a quicker spool up as well as a wider torque band and higher peak hp.

Don't forget the turbo inlet hose! The turbo also has to inhale well in order to generate big hp. One downfall of the eliminators is it is often shipped with a "reducing" inlet adapter. This allows the factory inlet hose to connect to it easily. By removing the "restrictive" inlet adapter, you can unleash a great deal of potential built into the turbo. Don't be surprised if 30 to 40 whp hp and 1000 rpms earlier spool up is achieved with an upgraded inlet pipe. This has been proven many times over on many dyno sessions
