PERRIN Rotated Turbocharger kits include everything for your properly tuned WRX/STI. PERRIN kits are designed to bolt to factory exhaust manifolds and catback exhaust.
Simply add a PERRIN front mount intercooler, PERRIN injectors and fuel rails, ECU tuning, Exedy Clutch, PERRIN cat-back Exhaust and you are ready to claw apart the surface of your local racetrack! All systems have a fully recirculated wastegate dump tube to prevent fire, noise, and stench.
All turbo kits come with a default oil line for a 2004-2006 model years STI north American version. Other models will require proper oil lines.
Overall Kit Design The PERRIN Rotated Turbo kits were originally designed for the customer that needed something bigger and more efficient than a stock location turbo replacement. A stock location turbo has 2 problems areas that cause inefficiencies, and loss in possible overall horsepower: the intake path and placement of turbo. Both limit the size of turbo and sacrifice intake path restrictions, again limiting potential horsepower.
PERRIN Rotated is Better! The PERRIN rotated kit is just that, rotated! Because they rotate the turbo to the side of the engine they can use a larger, smoother and straighter intake system. , and pretty much any size turbo you want! The PERRIN turbo kit places the turbo in the optimum position to attach to almost every aftermarket front mount intercooler.
New Cold Air Intake Hose Yes, Perrin's newly revised turbo kit includes a completely new 3" cold air intake system. This new inlet hose is designed to supplied fresh cold air to your Garrett GT turbocharger. The new intake has fittings for all your crank case, valve cover breathers, and other emissions control hoses. You will see 2 very important changes to Perrin's intake system.
-No MAF sensor housing = The MAF Sensor housing has been moved to Perrin's revolutionary new Blow-thru boost tube. The Blow-Thru boost tube places the MAF sensor inline between the intercooler and the throttle body. Now your ECU will receive a temperature correct reading. -No BOV recirculation fitting = For the first time you can now safely use a Vent to atmosphere blow of valve on your Subaru! Because they moved the MAF sensor to the Blow-thru boost tube just before the throttle body now vent extra boost pressure without the risk of running lean due to a loss of metered air. Any air vented from the blow off valve is now before the MAF sensor allowing the ECU to always receive a accurate reading or air entering the engine.
PERRIN intake systems always include a high flow foam filter element, perfect for large turbo applications. Also included are silicone adapters, and vacuum hoses for the installation. The new 3" pipe aluminum piping look good and out performs previous intake designs.
