Garrett GT Turbos
Garrett
claims the GT series turbos are much better then the old school
T series. They claim the GT turbos will spool about 1,000
rpm lower then the previous generation. Here are the Specs
of each turbo and compressor map. I also included the
1UZFE to 3UZFE Airflow.
Here are
the Air Flow Chart for the UZFE:
