The FP Green HTZ features the Green HTZ compressor section with the 60mm Flow Advancement Port compressor cover coupled to the 8cm2 turbine section. This combination produces the fastest spool and transient response possible in any EJ based turbocharger. The Green HTZ will flow 61lbs a minute and is capable of producing upwards of 425 horsepower (for comparison, a VF34 produces ~31LB/Min).

Please read below to determine which oil line fits your application.

We offer two different types of oil lines that will fit most WRX/STI year models (see photos above). However due to part number changes year to year and make to make we can not solidly identify which line you need. So below is a description of the lines and instructions on how to determine which one you'll need for your application. These are not made to work on anything other than Impreza WRX/STIs and we do not know if they will work on other models such as Legacy and Outbacks.

• Type 1 - This line is to be used if at the oil feed location off the back of the head only feeds the turbo. See the diagram on the right in the photos above, if you have that type of oil line you will use the Type 1 line. This was formally known as an non-AVCS line.
• Type 2 - This line is to be used if at the oil feed location off the head splits and feeds the turbo and the AVCS solenoid. See the diagram on the left in the photos above, if you have that type of oil line you will use Type 2 line. This was formally known as the AVCS Line.
