BorgWarner 2006+ Mini Cooper JCW Twin Scroll Upgrade Turbo

BorgWarner's K03-2074 turbocharger (part# 5303-988-0146) is engineered to be a reliable and high-performance bolton upgrade turbo for the 2006+ Mini JCW (up to 255hp).

Mini John Cooper Works upgrade from BorgWarner AirWerks features

• High temperature alloy turbine housing
• Extended tip compressor wheel
• Twin scroll turbine housing
• Water cooled bearing housing

Using a high-flow twin scroll turbine housing combined with BorgWaner's extended tip compressor wheel design - this turbocharger delivers early spool and outstanding boost response with torque and power gains across the powerband. Full-Race recommends the addition of an aftermarket exhaust system to compliment this turbo, although that is not required for the installation.

Additional Information:

• Max warm oil pressure: 5 bar (73.5psi)
• Max cold oil pressure: 8 bar (118psi)
• When starting a fresh engine build or in extremely cold climates - oil pressure must reach 0.5bar (7.2psi) within 4 seconds maximum.
• Do not load the engine with full boost and WOT until full operating oil pressure is present
• Do not load the engine with full boost and WOT if any boost leaks are present (this can result in turbocharger overspeed)
