Forced Performance Blue 73HTZ 84mm Ball Bearing Turbocharger - 2004+ Subaru STI | 2002-2014 WRX
The XR Blue™ turbocharger for the Subaru WRX/STI features the 73mm HTZ™ compressor section with your choice of 58MM stock appearing cover or 84MM Flow Advancement Port™ compressor cover coupled to the 8cm2 turbine section. This combo produces the best balance of spool and power available on this platform.
The XR Blue™ flows 57LB a minute and is capable of producing upwards of 475WHP. In addition to the things you know and love about the journal bearing FP Blue™, this unit utilizes our XONA Ball Bearing CHRA for increased durability in situations where you might see low oil flow such as road racing or autocross applications. All Subaru XR turbos are shipped with an oil return flange and a set of -4 water fittings to create custom water feed/return lines.
In the past we have sold two different types of oil lines. They were known as Type 1 or Type 2, and it was too easy to get confused as to the type needed due to various model differences across the years. To solve this problem, we developed a new oil feed line that includes the parts for both Type 1 and Type 2 cars. The installation instructions below will show which parts to use based on which type of car you have, which is why we are still using the Type 1 and 2 designators.
- Type 1 - Type 1 instructions are to be used if the oil feed location off the back of the head only feeds the turbo. If you have that type of oil line you will use the Type 1 instructions. This was formerly known as the non-AVCS line.
- Type 2 - Type 2 instructions are to be used if the oil feed location off the head splits and feeds the turbo and the AVCS solenoid. If you have that type of oil line you will use Type 2 instructions. This was formerly known as the AVCS Line
