If the cost is around 1,000 I'll just by the Green Diesel Engineering unit. His $2500 kit includes adaptor for manifold mounted to turbo, Custom exhaust pipe, And performance tune matched to new turbo (his other tunes cost 500 alone). He dyno tested it to 218hp and 400lb/ft max (torque limited to 270 lb/ft in torque convertor lockup)
From GDE site description.
The Stage II Turbo kit for the Jeep Liberty CRD centers on a new turbo charger assembly. The turbo is a generation III version of the production turbo on the KJ. This turbo has higher rpm limits, pushes more air and has a smaller frame size with lower rotating inertia. The core benefits with this turbo include
faster boost spool up providing quicker response and increased passing capability,
improved fuel economy, and increased top end performance. This turbo is not controlled with vacuum, but employs an REA actuator with PWM control. This actuator is a much more accurate method of controlling boost pressure, much faster response time at sea level and in altitude. The turbo kit will require welding on the exhaust system due to different exhaust downpipe and a couple wiring changes to power the turbo. A mounting boss for a thermocouple will be included on the exhaust downpipe. The kit will contain all hardware necessary to perform the upgrade with detailed instructions to allow self installation if you are so inclined. Otherwise a professional mechanic can complete the upgrade for your vehicle.
- What comes in the box:
- Brand new turbocharger assembly, modified by Green Diesel for fitment on the KJ engine
- Wiring connection to adapt previous connection to vacuum modulator to REA on new turbo
- New oil feed and drain lines
- New support bracket
- New turbo downpipe. You will remove the stock downpipe in front of the flexible coupling and attach the new downpipe.
- The kit will have provisions already included for installing an EGT probe pre- and/or post-turbine. Both locations will be plugged upon delivery, simply unscrew the one
you wish to instrument and install your thermocouple.
- New ECU tune (this is mandatory and is included in the price of the kit). No other tune (our Eco-tune, OEM, etc) will be compatible with this turbocharger. - See more at:
