2013 Subaru Forester XT Sleeper with COBB AccessPort


When our customer, Will, told us he was building a sleeper 2013 Subaru Forester XT Turbo, we were intrigued! Check out the modifications below that allowed for him to create 228 horsepower at all 4 wheels, and a very impressive 351 ft/lbs of torque! All of this through a stock exhaust, with minimal mods. The COBB AccessPort is a great tuning device, and we covered it in this other post previously.

I looked long and hard for a 2013 Forester XT Touring with low miles, finally I tracked one down 175 miles away. It was well worth the search amd the wait. Before I even had license plates I had to fix the body roll and release the power held back by restrictive parts and tuning. It's now making a peak of 351awtq and 228awhp running 16lbs of boost on a custom map from PIA in Tacoma, WA. I kept the exhaust stock for road trips, and so my wife wouldn't kill me. My 16 month old daughter loves the car and makes growling noises every time I start it up. Thanks to Redline360 and PIA for the amazing customer service and mods. It's truly an amazing sleeper, and handles perfectly for daily driving and the ocassional (okay, more than ocassional) hard corner. I would highly recommend both Redline 360 and PIA to anyone looking for their car to perform at its best!

What an awesome daily driver! What do you think? Let us and Will know in the comments below!


Ultimate Guide: Subaru BRZ Lowering Springs and Scion FR-S Lowering Springs Reviews


We have a lot of customers with the Subaru BRZ and Scion FR-S asking us what lowering springs we recommend. It's really difficult to say as the brands we carry are all high quality, so the decision really lies in the drop you want, and the spring stiffness. It also depends on what type of driving you will be doing. So what we did was put together a list of the Scion FR-S Lowering Springs and Subaru BRZ Lowering Springs that we carry to help you decide on what is best for you.

We'd love to hear your reviews and feedback in the comments. Let us know what your favorite springs are for your FR-S or BRZ.

Swift Race Spec-R Lowering Springs
Swift Lowering Springs Scion FR-S/Subaru BRZ [Race Spec-R] - Part # 4T909R

Lowers in the front: 1.1"
Lowers in the rear: 1.0"
Spring Rate: Linear

Review: For those who care more about handling and performance that the amount of lowering, Swift springs are our favorite. Swift has made a name for itself with coilover springs and has recently released it's own line of lowering springs and it's making waves. Absolutely excellent springs and they are designed to be used with stock shocks.

TruHart Lowering Springs
TruHart Lowering Springs Scion FRS/Subaru BRZ - Part # TH-S406

Lowers in the front: 1.75"
Lowers in the rear: 1.25"
Spring Rate: Progressive
Warranty: Lifetime

Review: TruHart is an entry level spring with handling and performance that surprised us. The ride is firmer but still comfortable, the lowering is aggressive, and a lifetime warranty protects against any manufacturer defects. Great springs for those who want something cheap yet functional and quality. Performance shocks recommended.

D2 Racing Lowering Springs
D2 Racing Lowering Springs Scion FRS/Subaru BRZ - Part # D-SP-SC-06

Lowers in the front: 1.75"
Lowers in the rear: 1.25"
Spring Rate: Progressive
Warranty: Lifetime

Review: D2 Racing lowering springs are one of the most popular for the FT86 platform. Great ride, aggressive lowering and one of the best priced springs available. Aftermarket shocks are recommended with springs that lower so aggressive.

B&G S2 Sport Lowering Springs
B&G S2 Lowering Springs Scion FR-S - Part # 92.1.101
B&G S2 Lowering Springs Subaru BRZ - Part # 86.1.030

Lowers in the front: 1.4"
Lowers in the rear: 1.4"
Spring Rate: Progressive
Warranty: Lifetime

Review: B&G Lowering Springs are nice for those who want to lower their BRZ or FR-S but maintain a good ride. B&G offers almost a 1 and a half inch drop front and rear which is more geared toward the aggressive drop.

Eibach Pro Kit Lowering Springs
Eibach Pro Kit Springs Scion FR-S - Part # 82105.140
Eibach Pro Kit Springs Subaru BRZ - Part # 82105.140

Lowers in the front: 1.0"
Lowers in the rear: 1.0"
Spring Rate: Progressive
Warranty: Million Mile

Review: Eibach Pro Kits are great for those who want to reduce some of the fender gap, but don't want to be too low. One inch drop front and rear is considered minor, but it's good for those who don't want to worry about rubbing aftermarket wheels and tires on their fenders. Of course it depends on what size aftermarket wheels and tires you run, but this is a generally a safe bet. Great ride.

Eibach Sportline Lowering Springs
Eibach Sportline Springs Scion FR-S - Part # 4.10582
Eibach Sportline Springs Subaru BRZ - Part # 4.10582

Lowers in the front: 1.4"
Lowers in the rear: 1.4"
Spring Rate: Progressive
Warranty: Million Mile

Review: If the Eibach Pro Kits didn't lower your car enough, the Sportlines might be for you. Eibach Sportline is made to lower about half an inch more than the Pro Kit, so you get a more aggressive stance and clear up even more of that wheel gap.

H&R Sport Lowering Springs
H&R Sport Lowering Springs Scion FRS - Part # 4408
H&R Sport Lowering Springs Subaru BRZ - Part # 54408

Lowers in the front: 1.0"
Lowers in the rear: 1.2"
Spring Rate: N/A
Warranty: N/A

Review: H&R Sport Springs give you about the same drop as the Eibach Pro Kit, but lower a bit more in the rear. H&R prides itself on offering a good ride, and many of our customers give their Sport springs great reviews.

H&R Super Sport Lowering Springs
H&R Super Sport Lowering Springs Scion FRS - Part # 54408-77
H&R Super Sport Lowering Springs Subaru BRZ - Part # 54408-77

Lowers in the front: 1.2"
Lowers in the rear: 1.4"
Spring Rate: N/A
Warranty: N/A

Review: H&R Super Sport Springs are for those who want to be a bit lower than what the sport provides, so these lower the car an extra .2" front and rear.

Hotchkis Lowering Springs
Hotchkis Lowering Springs Scion FR-S - Part # 19445
Hotchkis Lowering Springs Subaru BRZ - Part # 19445

Lowers in the front: 1.0"
Lowers in the rear: 1.0"
Spring Rate: N/A
Warranty: 3 Years / 36,000 Miles
Made in the USA.

Review: Hotchkis springs, made in the USA, are designed for comfort in the mind. Minimal lowering, but enough to close the gap.

Megan Racing Lowering Springs
Megan Racing Lowering Springs Scion FRS/Subaru BRZ - Part # MR-LS-SFR12

Lowers in the front: 1.75"
Lowers in the rear: 1.25"
Spring Rate: Progressive
Warranty: 3 Years

Review: The Megan Racing springs are for those who want a serious drop. These are designed to go low, but still offer a good ride. One thing common with springs that have big drops is they tend to sag even more over time. Megan Racing springs are unique in that they have a very high tensile strength steel that resists this premature sagging pretty well.

Manzo Lowering Springs
Manzo Lowering Springs Scion FRS/Subaru BRZ - Part # LSSFR-12

Lowers in the front: 1.75"
Lowers in the rear: 1.25"

Review: Our least expensive spring offered for this platform, yet comparable to more expensive springs. Good ride quality, good handling and braking improvements and good craftsmanship. Great entry level spring that offers aggressive lowering. Recommended to use performance shocks with these. It appears to be a common thread that the lowest priced springs all have the same amount of drop.

RS-R Super Down Lowering Springs
RS-R Lowering Springs Scion FR-S [Super Down] - Part # T065S

Lowers in the front: 1.1"
Lowers in the rear: 1.3"
Spring Rate: N/A
Warranty: 1 Year / 12,000 miles.
Made in Japan.

Review: RS-R Springs, made in Japan, are arguably the best riding springs we sell. RS-R really takes the daily driver into consideration to create a lowering springs that works with the OEM geometry, lowers just the right amount, and maintains a comfortable ride. These springs are actually designed to be used with the factory shocks.

Tanabe GF210 Lowering Springs
Tanabe GF210 Lowering Springs Scion FRS/Subaru BRZ - Part # TGF166

Lowers in the front: 0.6"
Lowers in the rear: 0.9"
Spring Rate: N/A
Warranty: N/A

Review: Tanabe GF210 lowering springs give you the least amount of drop that we sell. This is good for those that want to lower their car a little, and want to keep as much of the factory ride as possible. These springs are also made for those who want a soft and supple ride. Really for those who want to reduce just a bit of wheel gap, not have a noticeably lower car, and retain as much ride quality as possible.

TEIN HTech Lowering Springs
TEIN HTech Springs Scion FR-S - Part # SKSA0-G1B00
TEIN HTech Springs Subaru BRZ - Part # SKSA0-G1B00

Lowers in the front: 1.0"
Lowers in the rear: 0.8"
Spring Rate: Progressive
Warranty: 1 Year

Review: TEIN HTech lowering springs, also known as High Tech, are TEIN's luxury springs, which are designed to give you a modest drop with maximum ride comfort. Good for those who are all about the ride, and just want to close some of the wheel gap.

TEIN STech Lowering Springs
TEIN STech Springs Scion FR-S/Subaru BRZ - Part # SKQ54-AUB00

Lowers in the front: 1.4"
Lowers in the rear: 1.2"
Spring Rate: Progressive
Warranty: 1 Year

Review: TEIN STech Lowering Springs are a relatively aggressive drop, but still offer much of the benefits of a more luxury spring as ride comfort is key. TEIN STech's are a popular choice as they have a drop that most customers are looking for without being too aggressive.


Scion FR-S with a Supra 2JZ Twin Turbo Swap


Now we're talkin'. This 2013 Scion FR-S is fitted with a 2JZ Twin Turbo engine found in the 1993-1998 Toyota Supra Turbo. They did a custom single turbo setup and what looks like a lot of modifications on this thing, so I wouldn't be surprised if it's making in excess of 1000 horsepower. We've also seen the FRS and BRZ platforms with V8 swaps, so it appears this lightweight RWD car is going to be the recipient of many donor motors to come, and we love it.

Previously, we've discussed the Subaru STi 2.5L swap into the FRS/BRZ, and if this car would come with a turbo motor from the factory. Doesn't look like it'll happen soon, so these types of swaps will likely become more popular over time.

GReddy Turbo Kit for the Scion FRS and Subaru BRZ 11510094


GReddy has released their highly anticipated T518Z Tuner Turbo Kit for the 2013+ Scion FR-S and Subaru BRZ! The turbo kits should be shipping now and in stock by the first week in June!

With extensive testing both in Japan and the USA, this turbo kit was designed to enhance the overall performance for daily drivers and weekend racers. An ideal turbo sizing maintains the vehicles balanced driver feel, by maintaining good low-end response with the factory engine components. But the most noticeable improvements can be noticed on the factory power-band's dip in mid-range torque and at high RPM top-end power.

GReddy has been producing some of the most popular turbo kits for many late model imports such as Honda, Toyota, Mitsubishi and Mazda. GReddy is known for their high quality turbo kits that offer excellent fitment, and good streetability and reliability with out of the box performance. Many standard turbo kits require that you provide your own engine management, but the GReddy kit comes with it, and gives you a very good base map that will allow you to enjoy the car right away. We still recommend a professional tune to make sure you get the most from your new turbo kit.


GReddy dyno test showed a +93.5 whp and +68.7 ft/lbs increase at 7 psi on a stock 2013 Scion FR-S with factory injectors and fuel pump, just adding a *GReddy-tuned EcuTek ecu, and a *GReddy Evo3 70mm exhaust (*not Included). But even more importantly, the mid-range torque from 3150-4750 RPM's are significantly improved over the stock torque curve.

The Tuner Turbo Kit includes: a top-mounted GReddy T518Z 10cm2 actuator turbo on an equal length 4-1 SUS header-type exhaust manifold with dual flex joints, SUS downpipe and cat-delete, free- flow Airinx AY-SB intake, short-routing intercooler piping, Type-40E front-mounted intercooler with cast end-tanks and all the necessary brackets, heat-shields, hoses, clamps, and gaskets.

AVO Stage 1 Turbo Kit for the Subaru BRZ and Scion FRS


AVO's front-mounted Stage 1 turbocharger kit for the Subaru BRZ and Scion FR-S is finally ready and Redline360 expects to have it's initial order at our warehouse and ready to ship to customers by mid July!

The kit is designed to work with both RHD and LHD models in all countries, with extensive testing done on both the Japanese Subaru BRZ and the US Market Scion FR-S with the 6 speed manual transmission.

The turbocharger kit is designed from top to bottom specifically to the FR-S and BRZ and consists of all the parts necessary to bolt the kit up to the car. Thew kit utilizes an AVO 18/49 turbocharger that mounts up under the front of the engine via an AVO stainless steel unequal exhaust manifold, and then it bolts up to the stock exhaust with the AVO polished stainless steel turbo outlet (also referred to as a downpipe). Cooling the pressurized air is an AVO aluminum bar and plate front mount intercooler which uses black piping throughout, mechanical oil scavenging pump, oil reservoir tank, and all necessary water and oil hoses and fittings. Tuning is Ecutek tuning tools.

The turbo kit was designed to bolt up to the stock air intake box and stock exhaust system. AVO spent a lot of time ensuring it will work with the standard fueling system for a complete bolt on and go setup. The beauty of the system is that it looks very stock from above! The FMIC has been specifically designed to fit with the standard bumper without trimming as well, and on FR-S models would be be difficult to see unless you are looking for it.

From AVO's testing, the kit can be expected to produce anywhere from 220 to 250 whp on pump gas, dependent entirely upon the quality of the pump gas. This is due entirely to the fact that the stock motor is 12.5:1 compression, incredibly high for a n/a motor. This makes gas quality even more important than ever!

Kit Component Specifications

Turbo Specifications: The AVO 18/49 Turbocharger comes with a 5-7 psi actuator for precise boost control at lower psi levels, ensuring engine longevity. The turbocharger is rated for 380 hp of flow, so there is certainly headroom available with it from the base stage 1 kit.

Mechanical Oil Pump Specifications: The AVO kit is unique because it utilizes a mechanical oil pump that located at the back of the engine and runs off the back of the RH camshaft. There is also a oil reservoir tank right off the turbocharger itself. This is the most reliable way to pull oil through the turbo to the engine, as it keeps the flow rate tied to the rpm speed of the motor, ensuring that it's properly scavenged at low RPM's and idling, and has enough at high RPM's.

Front Mount Intercooler Specifications: AVO Bar & Plate Aluminum Intercooler with cast endtanks. Length = 19" Height = 8" Width = 3", The intercooler kit utilizes black wire- reinforced silicone piping and two black powdercoated steel piping. The intake piping has ports to mount up a variety of blow-off valves, even OEM ones for a full stealth look.

Part Number: S6Z12GS7A003T

MSRP: $4400.00 for the ceramic coated (which is the only option Redline360 has available for pre-order).


“Project Wreckless” – Gabriel’s 2004 Subaru WRX


Gabriel's 2004 Subaru WRX caught our eye as having a unique body kit and airbrush paint design that we haven't seen before. Gabriel studied to be an automotive mechanic at Automeca in Puero Rico, and his brother is helping him with the body work.


From Gabriel:

Project Wreckless is how i called this car i wanted to have a different look but keeping it looking like a WRX (not that I got anything against the STI's) so my brother help me out to install and paint the kit and some custom airbrush-paint designs to get that look that I wanted. The car still have minor details since we paint everything in a Barn house in W.V but the car looks just how I imagine it. I'm looking forward to get me a pair of coil-overs now so I can get that aggressive stance. Once I finish with that ill be getting some forged internals and a bigger dual-ball bearing turbo I have in mind to push 400 HP in this EJ20 on the future that's my goal on this project on this DD car step by step one thing at a time.

Pretty cool video of a stock Subaru BRZ trying to do some Gymkhana style racing. Looks like this guy ran out of milk and wanted to impress his girlfriend with morning breakfast. What better way to get milk in the morning that to Gymkhana around a farm?
