PERRIN Performance Rotated Turbo Kits have been a staple in the Subaru performance world since the introduction of the STI in North America. You will find the PERRIN turbo kit on many of the best built race and show cars in the world. The demand for this type of quality turbo kit for the new generation of Subaru's has lead us to introduce the PERRIN Performance Rotated Turbo Kit for the 2008+ STI and 2008+ WRX.
This new generation of Rotated Turbo kit has all the quality and superb fitment of the older kit in a package that fits the newer cars. Available in 400hp - 550hp+ capable kits. You can choose from the popular GT3076.82AR or GT3582R.82AR Garret turbos or special order any compatible GT3071R, GT3076R or GT3582R. The kits come with PERRIN/Tial 44mm waste gates, black silicone couplers, red or black aluminum cold air intakes, fully polished 304 stainless steel up and down pipes and all the required installation hardware. We even pre-assemble the kit so all you need to do is hook up a couple oil/water lines, bolt it in and go.
To get this kit running you will need a high capacity fuel pump, larger injectors and a method of tuning the combination.
So you want the most out of this kit? Look into a high flow 3" exhaust, high flow fuel rails, equal length header, Front Mount intercooler, Blow Thru boost tube, E.B.C.S., and high capacity clutch. In extreme applications you should install forged pistons.
For a turn-key, reliable, true bolt on 400hp PERRIN Performance will be offering a complete package in Spring 2009 that will include everything needed including the tuning. This will be accomplished using the popular AccessPORT ECU reflash module and a specially calibrated PERRIN Performance map.
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 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.
Intake System - New Cold Air Intake Hose
Yes our 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.
UppipeUp-pipe
The 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.
Downpipe
The downpipe is TIG welded, CNC mandrel bent, 3" 304SS tube with .500" CNC cut flanges. The PERRIN downpipe features an auxiliary dump tube to recirculate exhaust gasses from the waste gate back into the exhaust system eliminating the risk of fire and melting components from high heat associated with wastegates that just dump under the hood. The PERRIN downpipe dump tube features a floating flange design which can move and adjust to the extreme exhaust temperatures. The tight slip fit allows for expanding and contracting of the wastegate dump tube while still proving a nice tight seal. This slip fit also allows for easy quick removal of the wastegate with out having to unfasten V-band clamps, or flange connections.
At its base the downpipe features a exhaust flange designed to bolt up to your OEM catback exhaust. In turn most aftermarket catback exhausts and the original stock exhaust system will bolt right up to our turbo kit. Of course any of the PERRIN Catback exhaust systems will bolt up too.
PERRIN/TiAl 44mm Wastegate
This Wastegate is a key part to controlling boost. We choose the Tial™ 44mm with V-band connections. V-band connections allow for a tighter more compact install of the turbo kit. Tial™ is a premier brand specializing in wastgate design. Their high quality NiCrFe based alloy valves and 347SS valve housings will offer longer product life compared to competing designs. A 17-7 PH Stainless Steel actuator spring gives consistent pressure at high temperature, resisting "relaxing" at temperature to 900F (483C). The 44mm model features a larger diameter valve compared to other kits, which makes for flawless boost control. A 14psi WG spring is included with the kit but many other spring choices exist!
Exhaust Housing Size Selection
Most PERRIN turbo kits come with two exhaust housing options. .63AR, and the .82AR. The AR in simple terms is the overall size of the housing. A larger number indicates a freer flowing housing. A larger housings flow more air, but at a lower velocity which in turn has less energy spool the turbo. Though more airflow does equal more upper end horsepower, a larger AR will increase boost lag. The smaller AR. will spool the turbo faster it will have lower horsepower on the upper end.
