Top |

|
|
|
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.

Brand: FP
Desc: 02-07 WRX/STi
Type: RED Turbo
Status: Out of Stock
Price: N/A

The FP RED™ for Subaru STI/WRX has a flow rating of 950cfm or about 65lb/min. It features a large TD06 turbine wheel and is generally run in the larger 8cm turbine housing for max power.
The 3" inlet of the FP RED™ for Subaru STI/WRX means that the TGVs will need to be removed from the vehicle to gain the required compressor housing clearance.
If you select the internal wastegate option, your turbo will be fitted with a 14psi wastegate actuator. If you need a lower pressure actuator you will need to call to select that feature for your turbo because very few applications should require this option.

Since 2002 The Subaru WRX and STI have enjoyed the power and performance of the Forced Performance FP GREEN™ for Subaru STI/WRX turbochargers. These "bolt-on" hybrid turbochargers redefined the boundaries of power and performance while avoiding the "rotated mount" type kits.
The new for 2008 HTA update for the FP GREEN HTA™ for Subaru STI/WRX delivers an increase in maximum flow rate from 49lb/min to over 56lb/min without an increase in turbo lag, while also decreasing compressor outlet temperatures with better compressor efficiency than previous models.
The FP GREEN HTA™ for Subaru STI/WRX turbo features a 8cm Subaru flanged internally wastegated turbine housing with 1 bar actuator and your choice of 3" compressor housing or the more compact 2.4" compressor housing for applications retaining the TGV setup.

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.

The process of compressing incoming air to create boost and power also has a nasty byproduct of heat. Heated air lacks the density to make higher horsepower, increases detonation and forces the ECU to pull timing. All of which reduce the power you are looking to create.
Easy solutions do exist for this problem and PERRIN™ offers several choices for your vehicle and personal taste. For mild modifications and a stealthy look turn to our Top Mount Intercooler upgrades, available for Impreza, Forester, and Legacy models. These bar and plate cores offer more surface area per square inch than cheap tube and fin choices from our less worthy competitors and the overall size is more than 200% of the OEM unit! But Top Mount Intercoolers do suffer from underhood heat buildup and while excellent for mild performance gains the Front Mounts are the ideal choice for all out, bar none HP gains!
