Perrin Garret GT3582R .82AR Turbo Kit Subaru WRX STI 02-07

Perrin Garret GT3582R .82AR Turbo Kit Subaru WRX STI 02-07PERRIN Rotated Turbo kits include everything for your properly tuned WRX/STI. PERRIN kits are designed to bolt to factory exhaust manifolds, and to factory catback exhaust.Overall Kit DesignThe 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.The PERRIN rotated kit is just that, rotated! Because we rotate the turbo to the side of the engine we can use a larger, smoother and straighter intake system. , and pretty much any size turbo we 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 HoseYes Perrin's newly revised turbo kit includes a completly new 3" cold air intake system. This new inlet hose is designed to supplied fresh cold air to your Garrett GT turbo. The new intake has fittings for all your crank case, valve cover breatherst and other emissions control hoses. You will see 2 very important changes to our intake system. * No MAF sensor housing The MAF Sensor housing has been moved to our revolutionary new Blow-thu 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 we 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.Up-pipeThe PERRIN Rotated Kit up-pipe is a TIG welded, CNC mandrel bent, 2" 304SS tube with .500" CNC cut flanges. The external waste gate is plumbed into the up-pipe with a smooth transition from the wastegate to the exhuast system allowing for smoother exhaust flow and greater control of boost levels. The up-pipe is designed to bolt to a factory exhaust manifold for those who choose to use the stock manifold. We do recommend that you consider the PERRIIN exhaust header. It is a great way to lower the spool RPM, and make more power throughout the RPM band.Down PipeDownpipeThe downpipe is TIG welded, CNC mandrel bent, 3" 304
