Click the image above to enlarge. |
The Perrin 02-09 WRX & 04-09 STi rotated mount turbocharger kit is one of the most comprehensive and best-designed on the market. The Perrin rotated mount turbo kit utilizes redesigned exhaust and intake plumbing to install a large Garrett Turbocharger on your WRX or STi, without being limited by the stock under-the-manifold turbo inlet and internal wastegate. Perrin's rotated turbo placement allows for straight, unobstructed intake plumbing and fitment of even the biggest turbochargers, like the Garrett GT40R!

| Perrin Rotated Mount Turbo Kit Components: |
 |
Rotated Mount Uppipe & Downpipe: |
Constructed from mandrel bent 304 stainless steel with .500" CNC-cut flanges, the Perrin rotated mount uppipe and downpipe are both tig-welded to the highest quality standards. The Perrin rotated mount uppipe features 2" diameter piping, and is flanged for an v-band Tial 44mm external wastegate for precise boost control. The Perrin roated mount uppipe will bolt to a stock exhaust manifold, or aftermarket header designed for a factory 2-bolt uppipe; we suggest the Perrin equal-length exhaust header for optimal performance.

Perrin's rotated-mount WRX & STi downpipe features full 3" piping, all the way into the turbo, and is designed to recirculate the Tial 44mm wastegate back into the exhaust path, instead of using an external dump. Recirculating the wastegate gases eliminates the risk of fire and melting from engine bay heat, it also significantly reduces noise. The slip-fit flange design allows for perfect fitment, and expansion under the extreme post-turbo heat to resist cracking. At the downpipe's base, is a 3" flat flange, that will bolt up to a stock exhaust or stock-location aftermarket catback exhaust.

Rotated Mount Cold Air Intake: |
| Recently added to the Perrin WRX & STi rotated-mount turbo kit is the 3" cold air intake system. Designed to draw cold air from the fenderwell directly into the Garrett turbocharger, without any restriction from a MAF sensor, Perrin's new cold air intake will ensure optimal airflow and increased power. In addition, the Perrin cold air intake system has all the necessary fittings for the crankcase vents, valve cover breathers, and emissions control hoses for direct installation. The Perrin WRX & STi rotated mount cold air intake eliminates the MAF sensor housing for optimal flow and minimal turbulence. Because of the removal of the MAF housing from the intake tract, the Perrin turbo kit requires that you switch to a blow-through MAF type system (where the MAF sensor is placed in the intercooler piping), or convert to a full speed density system, eliminating the MAF sensor entirely. Perrin makes a blow-through intercooler pipe (sold separately) to make this conversion a simple process that will make your Subaru perform better and run more smoothly with a big turbo. |
| The Perrin WRX & STi rotated mount intake is constructed from 3" aluminium pipe for optimal flow and minimal weight. It is available in powdercoated red, powdercoated black, or polished finishes, so it looks as good as it performs. The Perrin rotated mount cold air intake system includes the proper sized turbocharger coupler, high-flow reusable foam filter element, and silicone vacuum hoses for proper fitment and installation. |
 |
Tial 44mm V-Band External Wastegate w/ 14psi Spring: |
| For precise boost control, the Perrin WRX & STi Garrett turbo kits use a Tial 44mm wastegate. The Tial 44mm Wastegate uses v-band connections to eliminate leaks and allow for installation in tight spaces (like the WRX & STi engine bay). The 44mm design releases exhaust gases faster, yielding spot-on boost control, and the valves are constructed from temperature resistant materials for excellent heat-handling characteristings. Loaded w/ a 14psi spring, this wastegate can be pulled up to around 28psi with a conventional boost controller or solenoid. If you need to go higher than that, an off-the-shelf Tial spring is available for almost any pressure requirement. |
 |
Garrett GT Series Dual-Ball Bearing Turbochargers: |
| Perhaps the most rugged turbochargers on the market, Garrett's dual-ball bearing turbochargers are designed for rapid spool due to their ball-bearing cartridges, longevity due to their oil & water cooled center cartridges and exhaust housing composition, and performance due to their large size. The Garrett GT turbos have become a staple of automotive performance, and are the basis for Perrin's WRX & STi rotated mount kit. |
| Most of the Garrett turbos Perrin offers are available in .63 & .82 AR exhaust housings; .63 will yield faster spool with less top-end, while a .82 housing will spool less rapidly but make more top-end power. With many different size options available, Perrin is sure to have a Garrett turbo to suit your needs. |
| Hardware: |
| In addition, the Perrin rotated mount kit includes all the necessary hardware, bolts, lines, and gaskets for proper installation. 02-05 EJ20 2.0L WRX owners will need to purchase an oil feed line, but all other models will find all the necessary turbocharger hardware for kit assembly in the package. |

NOTES:
1. The Perrin turbo kit either requires a Perrin front-mount intercooler with blow-through MAF tube, or some form of engine management that eliminates the MAF sensor. This kit makes no provisions for the stock MAF sensor.
2. Engine managment, fuel system upgrades, and supporting modifcations are required with this kit.
3. Professional installation is strongly recommended; this is not a task for beginners. We strongly suggest a shop familiar with Subaru performance.
4. Tuning will be required with these kits.
5. We strongly recommend considering engine internal upgrades for those looking to exceed 400whp on 2.5L cars (300whp on 2.0 WRXs).
6. As with all turbo kits, there is some "tweaking" / "elbow grease" required for installation - i.e. trimming, unbolting, minor grinding, etc. in varying degrees as each car is a little bit different. For this reason, we suggest professional installation by a Subaru performance shop (you can contact us for reccomendations).
7. 2005 STi models and all 5-speed models require some grinding of the transmission housing for clearance and a soft bend in the dip-stick sleeve for clearance.
8. This kit is designed for the Perrin front-mount intercooler and blow-through MAF tube.
9. Anything over a .63 GT3071R on a 2.0L will have lots of lag; the EJ20 will require internal modifications for proper use of any of the bigger turbos.
10. We recommend internal engine modifications for the GT3582R and above on the STi to maximize potential.

FITMENT:
1. Fits all 2004-2007 STi models; some STis (mostly 2005) require minor grinding of the transmission casting for clearance - 2007 STIs require an additional oil line.
2. 2002-2007 WRX and 2007 STi models: Require an additional oil line for fitment (sold separately below), some grinding of the transmission housing is required, and a bend in the dip-stick tube is required.
3. The 2008-2009 WRX & STi use a different kit than older models, please choose accordingly.
