Oil Supply Line now included!
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. 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 below, 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 below, if you have that type of oil line you will use Type 2 line. This was formally known as the AVCS Line.
Porting is available again for this turbocharger. Please take a look at our Porting Services page for examples:
For all of our journal bearing turbos we recommend a high quality oil see below for our oiling information sheet.
