PRODUCT DETAILS ▾
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.

- Oil Line - Included
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.
Subaru Oil Feed Line Installation Instructions.
Type 1 - Type 1 instructions are 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 instructions. This was formerly known as an non-AVCS line.
Type 2 - Type 2 instructions are 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 instructions. This was formerly known as the AVCS Line.
Attention: All Forced Performance turbochargers are built to order to your exact specifications and should not be considered on the shelf ready to ship unless specifically noted on the work order. Build times vary by model of turbo and options of said turbocharger, therefore we cannot guarantee a delivery date or ETA.
WHY WE CARRY THIS ▾
We only list parts we’d run ourselves or recommend to a friend building a real car. If it feels vague, unverified, or inconsistent, it doesn’t make the cut.
- Fitment-first mindset — no “universal” roulette
- Brand reputation matters — we favor proven manufacturing
- Support that actually responds with real answers
WHAT TO EXPECT ▾
This is the clean path: correct fitment, clean install, and results that match the intent.
- Install-ready experience with correct mounting where provided
- Finish that holds up to real driving, not just photos
- Selections on this page drive the exact fitment shipped
TRUST, BUILT INTO THE PROCESS.
Anyone can list parts. We curate what belongs on a serious build. Our goal is simple: fewer surprises, cleaner installs, and confidence when you hit “Buy.”
Fitment checked
We prioritize vehicle-specific listings and clear selection logic so you’re not gambling on compatibility.
Brand discipline
Proven manufacturing and consistent quality matter more than hype. We bias toward what actually holds up.
Real support
If you have a question, you’ll get a human answer that helps you finish the build — not a copy-paste shrug.
