RENNtech"s Stage I Turbo Upgrade for Mercedes AMG GT-S (C190)

The Mercedes GT-S is the second Mercedes-Benz vehicle fully developed by AMG, the company’s Affalterbach-based performance division and long fabled engine builder. The resulting vehicle is nothing short of spectacular and its 4.0L V8 BiTurbo engine is an incredible platform to build performance upon.

RENNtech lightweight forged billet turbo wheels feature a dramatically larger than stock impeller (inlet side) and an increase in the turbine trim (exhaust side). This combination of high quality, lightweight components compensates for turbo lag despite being a functionally larger turbo. The cartridge supporting shaft is also larger and stronger, therefore designed to handle the larger wheels and additional power. This entire cartridge is then fine balanced as a complete assembly to compensate for these increases. The impeller and turbine housings are then precision CNC machined and flow tested in-house to fit the larger internal cartridge. The end result includes gains up to 180 hp and 161 lb-ft of torque.

More power isn’t the only performance benefit as RENNtech’s turbos spool quicker, and offer a more responsive throttle and immediate power delivery thanks to a reduction in exhaust back pressure, rolling resistance, higher RPM’s and a lighter rotating mass. In addition, their turbo upgrade kit functions with the OEM oil and coolant lines. This isn’t just an OEM turbo charger with machined internals; but a dramatically larger, more powerful turbocharger that blows away anything else on the market!

The RENNtech performance turbo upgrade is truly the ultimate upgrade for your AMG GT-S. Check out the key features of this product and some images below. You can also browse through all RENNtech products here.

Weistec Goes Maniac on the Mercedes GT-S with Turbo Upgrade

Weistec Engineering is the go to source for Mercedes performance upgrades.  When a new Mercedes platform somes out, they go to town!  Already having some great upgrades for the 911 fighting GT-S Coupe, Weistec thought they would make the already 500+ horsepower monster even faster with a billet turbo upgrade.  The Weistec M178 W.3 Turbo Upgrade unlocks the true potential of the 4.0L Biturbo engine.  Power gains are substantial, especially in the top end.  As Weistec puts it, “The factory turbocharges are disassembled and fully inspected.  The compressor cover and center cartridge are then machined to accept our 5-axis CNC machined 65mm impeller wheel.  Externally, no changes are made to maintain a completely stock appearance.  The new impeller wheel supports greater power levels than the factory unit with little to no sacrifice in spool and response.  The turbochargers are then reassembled with new seals and fully balanced for smooth operation and OEM service life.  All the original oil and coolant lines bolt right up making for a simple install.”

As tested on their own shop car with supporting mods, the GT-S made 650 wheel horsepower!  Supporting mods include the Weistec ECU flash, downpipes, air filters, and of course, some good gas!  Shop all Weistec Mercedes Power Parts Here.
