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.
