When basic bolt ons won?t do or you have simply stalled out with the performance of the factory turbo then our Rotated Turbo Systems are the place to go! With kits that range in power totals from 250 WHP to more than 600WHP we have any boost junkies needs covered. We offer a range of turbos to fit a mild 2.0L engine, all the way to a crazy 2.5L wanting to break the 600WHP barrier.

The PERRIN Rotated Turbo kits include everything to bolt your turbo of choice to your properly tuned WRX/STI. The kits are designed to bolt to factory exhaust manifolds, and to factory catback exhaust. This allows the use of existing aftermarket headers, and catback exhaust systems to be used. The parts included with the kit are the uppipe, downpipe, PERRIN/Tial 44mm External Wastegate, Silicone intake system w/BigMAF housing, Intercooler pipe connectors, Oil lines for either WRX or STI, coolant lines, and PERRIN PyroShield hose cover, and of course your choice of a Garrett GT2860RS, GT2871R, GT3071R, GT3076R, GT3582R, and GT4088R.

Simply add your front mount intercooler, fuel system, ECU tuning, clutch, cat-back and you are ready to claw apart the surface of your local racetrack! All systems have a fully recirculated wastegate vent to prevent fire, noise and stench. These kits are not for the faint of heart and it is best to speak to a PERRIN? specialist before ordering. Let us cater the exact combination to meet your needs. We can help you choose the extras that make this project successful with ECU plug-n-play tuning, fuel pumps, etc. NOTE: Some systems do require engine modifications for optimum longevity. Fits all STi models 2004-2007.

BLOW-THRU BOOST TUBE MUST BE PURCHASED WITH THIS KIT IF THE FACTORY MAF SYSTEM IS TO BE RETAINED. IF YOU ARE SWITCHING TO MAP YOU DO NOT NEED THE BLOW-THRU BOOST TUBE.

All turbo kits come with a default oil line for a 2004-2006 model years STI north American version.
