Full-Race's 1.5 scroll header/up pipe kit for Stage2+ Subarus is engineered and dyno tested to produce the fastest spool, quickest response and most hp/tq gains for a stock location header. The 1.5 scroll system consists of the twinscroll lower manifold and stock location 1.5 scroll up-pipe. Designed to optimize performance for a stock location singlescroll turbo, the 1.5 scroll up pipe uses a twin-runner configuration with the final 2->1 merge collector in close proximity to the turbine. The 1.5 scroll combines twinscroll performance characterstics with the convenience, easy installation and OE appearance of the singlescroll stock location turbos. Any stock or upgraded-stock style turbocharger and aftermarket downpipe will fit, allowing Stage2 subarus to retain all current mods. For best results, Full-Race recommends using the ATP GT series turbochargers. Compatible for all RHD and LHD subaru chassis.

Notes on the Perrin Rotated Mount Turbo Kits:
- 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.
- Engine managment, fuel system upgrades, and supporting modifcations are required with this kit.
- Professional installation is strongly recommended; this is not a task for beginners. We strongly suggest a shop familiar with Subaru performance.
- Tuning will be required with these kits.
- We strongly recommend considering engine internal upgrades for those looking to exceed 400whp on 2.5L cars (300whp on 2.0 WRXs).
- This kit is designed for the Perrin front-mount intercooler ($1195) and blow-through MAF tube ($195).
- 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.
- We recommend internal engine modifications for the GT3582R and above on the STi to maximize potential.

The Agency Power GT35R turbo kit is designed to make over 500 wheel horsepower on race gas and over 400 wheel horsepower on pump gas as tested on the STI. The WRX will produce less horsepower on the stock motor. All numbers vary depending on car modifications, tuning, and environment. This turbo is custom designed to spool up at around 4000rpm's to give the best horsepower response throughout the powerband. The turbo is capable of running 30psi and greater of boost, however we recommend many modifications to ensure the safety of the motor.
We recommend having the following parts: Front Mount Intercooler, ECU, Fuel Pump, Injectors, Fuel Rails, Catback Exhaust. Other recommended parts would be to upgrade your clutch, flywheel, shifter, radiator, and other related parts.
