How does the Weistec W.3 Turbo Upgrade Work?
To perform this upgrade, your factory turbochargers must be sent in to us. Once received, they are disassembled and fully inspected. The
compressor cover and center cartridge are then machined to accept our 5-axis CNC-machined impeller wheel. Externally, no changes are made,
preserving a completely stock appearance. The new impeller wheel supports greater power levels than the factory unit with little to no sacrifice
in spool or response. The turbochargers are then reassembled with new seals and fully balanced for smooth operation and OEM service life. All
original oil and coolant lines bolt right up, making for a simple install.
If you prefer not to send in your turbos first, a core exchange option is available. With this option, upgraded turbochargers are shipped
to you up front for a refundable core charge. We refund the core charge once we receive your factory turbo units and they pass inspection.
