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:

  1. 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.
  2. Engine managment, fuel system upgrades, and supporting modifcations are required with this kit.
  3. Professional installation is strongly recommended; this is not a task for beginners. We strongly suggest a shop familiar with Subaru performance.
  4. Tuning will be required with these kits.
  5. We strongly recommend considering engine internal upgrades for those looking to exceed 400whp on 2.5L cars (300whp on 2.0 WRXs).
  6. This kit is designed for the Perrin front-mount intercooler ($1195) and blow-through MAF tube ($195).
  7. 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.
  8. 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.

Everyone has seen or heard about Evo3 16g turbos and TD05H 18g turbos for the Subaru 2.0 and 2.5 engines, our newest turbo is the FP 68HTA™Turbocharger for the Subaru STi/WRX unit which out flows both the E316g and 18g wheels and allows for higher PR operation without increased compressor outlet temperatures like the existing 16g and 18g wheels. Mass flow is increased to a whopping 47lb/min which is several lb/min greater than either the E316g or the 18g wheels are capable of. Rapid spool and large torque numbers are guaranteed by the TD05H turbine section.

These units are constructed from Genuine MHI 16g turbochargers which are reconfigured to 68HTA specs by Forced Performance.

Unlike other systems that require cutting of structural components at the front of the vehicle, APS has designed the D/R Series FMIC with a truly bolt-on replacement unit that not only maintains the structural integrity of the vehicle, but also forms the perfect mount to accommodate the largest FMIC available for a WRX and STI.

Another bonus for the Subaru performance enthusiast is that the APS D/R Series FMIC maintains the standard fog lights!

In the case of intercooling, where bigger is better, APS shoehorned the largest intercooler core possible into the WRX for maximum cooling capacity and engine performance. With intercooler core dimensions of 9.5" x 28" x 4.5" (24.1cm x 71.1cm x 11.4cm) for a surface area of over 266 square inches and a total intercooler core volume of 1,197 cubic inches (19,600 cm3) (the largest by far of aftermarket WRX and STI intercoolers) that's over 4.5 times the size of the standard top mount intercooler.

Stage 1 (266/266) Cams:
GSC Power-Division S1 camshafts for the USDM 04-07 STi. These will not drop any low end power, but actually cause faster spool of the turbo, creating more power and torque across the entire rpm range. Good for stock turbo or up to 500WHP(GT35R) upgrades. These cams require upgraded valve springs to keep everything safe at high rpm.

Stage 2 (272/272) Cams:
GSC Power-Division S2 camshafts for the USDM 04-07 STi. These cams are built to suite the high horsepower Subys. With a power range of 500WHP and up, you need some certain mods to utilize the true potential of the S2s. Built motor, with a built/ported head, and a good engine management system. Dual valve springs are recommended, but a upgraded single spring kit will do the job under 8000 rpm. **Due to the lob size, some head castings may need to be filled down slightly for clearance.

APS's WRX & STi cold air intake system is a great way to improve air flow, sound, and performance in your WRX or STi. Unlike short rams, which source hot air from under the hood, the APS cold air intake system breathes cool air from the inner guard for the optimum engine performance and durability. More importantly, the air through the APS WRX & STi high flow air intake system is consistent in temperature. This means that the engine management unit's temperature compensation system operates correctly - unlike devices that source air from the highly turbulent areas under bonnet. The APS WRX & STi cold air intake is available in two versions: 65mm piping diameter for stock ECU applications, and 70mm for high horsepower applications that need more MAF resolution.

The OpenPort bundle includes an LC-1, an OpenPort OBD2 cable, and the EcuFlash plugin for LogWorks. This bundle allows you to log data from any ISO 9141 (Chrysler, European, and Asian) vehicles, and reflash most popular late model Subaru and Mitsubishi cars, including WRX and Evo.

The value of this bundle is that your wideband air/fuel data is completely integrated with your factory ECU data.

This allows you to view fully-synchronous logs, and import all EcuFlash-defined 3D table data and formats directly from EcuFlash generated ROM files into LogWorks charting for easy computation and comparison. At $299, this is the most cost-effective Subaru and Evo tuning tool on the market.

The basis for our Stage 4 kit is the Garrett GT35R turbo kit by Agency Power. To obtain this power, you will need corresponding modifications as we have listed in the below options. The most important part of this kit is fueling and ECU tuning which Vivid Racing has accomplished with dyno testing using our Mustang AWD dynamometer. Our test car made 396 awhp on 91 pump octane. With a drivetrain loss of 25% for the Mustang dyno, this is 500HP to the crank. Expect higher numbers on 93octane and race gas. In combination with a turboback exhaust, intercooler kit, fuel system, and other bits and pieces, this Stage 4 kit will rocket you past the competition.
