Description
The Weistec BMW S55 W.3 Turbo Upgrade unlocks the true potential of the 3.0L Twin Turbo engine. Power gains are substantial, especially in the top end.
The factory turbochargers are disassembled and fully inspected. The compressor cover and center cartridge are then machined to accept Weistec’s 5-axis CNC machined 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.
For maximum results, a Weistec W.3 Turbo Specific ECU Upgrade is recommended.
