TPC25-660 Turbo charger - 02-07 WRX, 04-21 STI

TPC has updated our super20g ( K spec) with newer wheels. We have replaced the 20G compressor wheel with a more efficient  G series 660 inspired wheel. This new compressor wheel is larger than the 20G and flows more air. 

There is the choice of a 9 blade turbine wheels in a 49mm turbine wheel or a 54mm for those looking for more top end. We also offer the 49mm in a 5+5 option for more top end over the 9 blade 49mm wheel.

 This is a 100% bolt on for the 2008 - 2014 WRX STI sedan and hatchbacks.

The 49mm is designed for the quicker spool and more down low torque in mind. If you want something that will pull past red line then the 54mm is a better match for you. 

We recommend the 49mm for the 2L and 54mm for the 2.5L engines for optimal spool times. These combinations will get you in low 12s 1/4 mile times with supporting mods and fuel.

We only use high performance thrust bearing systems in our turbos to ensure your turbo is well protected under high boost.

You can choose what turbine housing you want. We offer 8CM OR 10CM turbine housings.

Our option 5+5 49mm turbine wheel is only available as a journal bearing turbo.

 A quality install kit with 5 ply gaskets is also included in the price.

Also available in an 8cm twin scroll housing for $250usd extra. Please contact us for this option

Turbos all 100% built and High Speed balanced in house on our VSR balancing machine.

TPC recommends to run the Perrin 2.4 inch turbo inlet pipe for maximum airflow into the turbo.
