The Original Direct-Fit BCS for Turbo Subarus.

GrimmSpeed is proud to provide themost completeandeasy to use3-Port Electronic Boost Solenoid for available for all turbo Subarus. Unlike your OEM 2-port solenoid, the GrimmSpeed BCS will allow for extremely high resolution boost control, providing your tuner with the hardware he needs to safely tune your car with rock solid boost levels. Using our solenoid, you are able to spool your turbo quicker and maintain tight control of boost levels throughout your power curve. In addition, our solenoid features a balanced valve to withstand up to 120psi without a slowing response by even a single millisecond.

Quick Specs

  • Decrease Spool Time- flows 10% more than the competition
  • Plug and Playinto OEM Harness - no splicing wires like other BCS solutions
  • Works Safely withFactory Subaru ECU -customcoil to match ECU voltage
  • Nickel Plated Fittings-not the easily breakable plastic fittings!
  • 15min Installation- extremely simple with our written and video guides

Design

Revolutionizing the Subaru boost solenoid market, we have created model specific install brackets that allow you to install our Boost Control Solenoid with a factory fit and finish.To top it all off, our solenoid also uses a Subaru wiring harness connector so that you can simply unplug your OEM solenoid and plug ours in. No more cutting and crimping OEM wires together!

The solenoid itself is one of a kind. MAC manufactures pneumatic control products for the largest commercial operations in the world, where every minute of downtime can cost tens of thousands of dollars, so we worked closely with their engineers to design this unique valve, incorporating proprietary features, exclusive to GrimmSpeed, that make our solenoid the toughest on the market. Those features include special seals to protect it from moisture and high temp coils to keep response times at 6 milliseconds or less, even in extreme heat. We have worked with many of the top tuners in the country to ensure that our solenoid works safely with the factory Subaru ECU.

Materials

Our special solenoid features, combined with our factory-fit brackets, ensure that this complete boost control solution will withstand the harsh heat and vibration of your engine bay. The Subaru harness connectors that we use include weatherproof terminal seals, carefully crimped with DELPHI equipment by our expert assembly staff. Mounting brackets are laser cut and then black zinc plated to ensure corrosion resistance. Each bracket has threaded PEM nuts pressed in for a solid connection with no risk of stripping threads. Each low profile 1/8" NPT nickel plated fitting is installed in the proper orientation using a 120psi thread sealant for a clean, compact, robust installation.

Trust Your Tuner

You don't need to take our word for it, trust your tuner. When it comes to boost control systems, be sure to consult with your tuner to ensure that you're building a setup that they're confident tuning. The good news is that with well over 25,000 units in use on some of the fastest Subarus in the world, with the GrimmSpeed Boost Control Solenoid, you'll be in great company. As with any change to your boost control system, upgrading to a 3-port solenoid does require tuning.

Electronic Boost Control Solenoid 3-Port - Subaru 08-14 WRX, 05-09 LGT, 9-13 FXT (11)

"The GS 3-port BCS provides rapid boost response while maintaining the ability to make acute adjustments via turbo dynamics. While many other boost control solenoids react to adjustments too fast which can make them difficult to control with as much finesse as the stock bleed system. This solenoid can make micro-adjustments at the edge of target boost not only providing better spool, but overall more control." - AWD Tuning

"The GrimmSpeed™ BCS is a compact, well designed unit. Its design as a 3-port solenoid provides better boost control then the stock bleed-type style. Often, this enables a tuner to cut mapped wastegate duty cycles in half. This change in WGDC gives a tuner more granularity when tuning, and can yield much improved boost curves. In addition, the 3-port design often significantly improves spool." - Bullwinkle Tuning

Grimmspeed ebcs

Its typical for USPS to drop the ball, the package was being bounced between multiple facilities and was "undeliverable". Grimmspeed support sent me another next day UPS, after just a few emails. The product is always good but the support staff really killed it.

The right part

Recommended by my e-tuner and delivered very precise control of the boost to help him do his job.

Great product

The fitment was great for my wrx and it definitely helps! Delivery was quick too. Tubing was a little weird to set up, but not that hard.

Fitment on 2010 WRX not so good

So I bought this based on info I had read and watching the install videos. Pretty straightforward install. HOWEVER they no longer carry a different bracket for the WRX and LGT. So I went to install this on my 2010 WRX like the LGT part of the video describes. The hose coming out of port 3 is right in line with the connector for the sensor that remains there. The part itself is great quality. Just wish they still had the other bracket that would mount this in the stock location... much cleaner and better install location without interfering with wiring.

easy to install/can see the difference

Product was easy to install, I used grimmspeeds YouTube channel which was very helpful. Took about 20 minutes to install. I can hear the turbo spool quicker and there's more boost. Defently recommend this product.

3 port boost control

works great, a little overpriced for what it is, according to my cobb tuner its the best one made. the only complaint i had was where they wanted me to mount it - i bought a nut and bolt and moynted it where the old 2 port was - all in all a good product however.

shadrach mykytiuk 30th Mar 2016

fine tuning

I had recently installed fmic n was in need of tuning. With the ease of installation, this Ebc had my car spooling quicker. My tuner had been fighting my stock boost control yet had me tuned in seconds with grimmspeed boost controller. Took away lag from extra piping. Thanks grimmspeed

Almost perfect

I purchased this product along with the Grimmspeed Intake for my 05 LGT. The product itself is quality built and has worked flawlessly after install. The only reason I did not give it 5 stars ( and this is being a little picky ) is that they use the same general design for the wrx and the LGT. So the fitment is very tight and feels like it just doesn't quite belong. I had to bend the bracket just slightly to keep it from rubbing up against other engine components. Aside from that a great upgrade.It is interesting to note that if you buy the two items as one of their performance packages it will cost you more than if you buy them separately. Not sure why they market this way but I would check each of their performance packages if you intend to buy them and check the prices. Response from GrimmSpeed: We're in the process of revamping all of our pricing and you must have 'snuck in' before that was complete. Power Packages are intended to be a better deal!

2nd one I have bought and installed.

...and like before, perfect. I am sold on this EBCS in so many ways. The install is super easy and the boost stays consistent. I would not use any other EBCS, period.Thanks again

Lance 19th Nov 2015

Great!

Great response, coming from using the oem boost control this one feels more responsive, boost comes on a lot quicker and my tuner was able to really dial in my car. It feels great now!

EBCS - Awesome!

Absolutely amazing product.

Recently purchased this 3 port ebcs to replace my stock one that malfunctioned on my 05 LGT. It absolutely blew my mind away how much it opened up the entire system and advanced throttle response. Highly recommend for anyone needing a replacement or just wants quicker response from their vehicle.

5/5

Jamie 19th Nov 2015

Easy installation, greatly reduces turbo lag

2004 wrx, stage 1 (Cobb v3) on 93 octane. Installed this EBCS and got a pro-tune. The car is finally pulling as hard as I want it to be. I may go stage 2, but for now I am very happy with the results.

Works great

Easy to fit and works like a charm on my 03 Forester 2.0 XT.Bolt-on and discrete.Wish the included vacuum hose was a bit longer, and could have used a few hose clips because they are easy to lose.

5/5

Andrew Jackman 19th Nov 2015

Highly recommend

Very satisfied. They sent me the LGT bracket even thou I selected 2011 WRX but it still worked, just not as clean looking as the WRX bracket. I'm fairly new to modding cars and was able to follow the instructions with no issues! Highly recommend!

Josh Wulff 19th Nov 2015

More boost no jotters A+

Put the bcs on took about 30 plug n play, mounting brackets alittle different on the 05 wagon, had to mount it upside down , but definelty worth the money. spools faster, more boost, no more gitters in first gear... good upgrade

Awesome power and customer service

Not only am I impressed with the awesome power and throttle response gains, I must say the customer service exceeded my expectations. Love the BCS without a doubt

Alexander Scott 19th Nov 2015

It is worth it

"my stock setup couldn't give me more than 12 psi no matter how aggressively i set the duty cycles. I replaced the bleed system with this one, and it is awesome. This item gives you so much more control over the turbo. Now i feel the need to dig out my Controls Engineering book to fine tune the Turbo Dynamics for even better response.seriously, if you are thinking about getting one, just do it. it's worth it, and it takes about 30 minutes to install in the driveway with a leatherman and a 10 mm wrench."

Solid boost response

Best replacement for OEM bleed system. Perfect fitment, stock location fast, solid boost response.

Definitely a fan

"got the 3 port solenoid installed this weekend and a retune from keith, running stage 2 with a grimmspeed ewg, and uppipe. Definatley a grimmspeed fan.Boost hits so fast and along with keiths tweaking to my drive by wire, I'm now going to run over an old lady in a grocery store parking lot on accident from hitting boost in first.+1 for GS ebcs."

Boost comes on fast and rock solid

"Installed my Grimmspeed BCS last week with my Labonte Meth kit.She's all tuned and I LOVE it. Boost comes on so fast and it holds rock solid. With my stock VF48 I'm peaking 23PSI and tapering to 19!!"

Got mine on last week and had my tuner ([emailprotected] Motorsports) adjust for it. It is way better than my GM BCS. I would recommend it to anyone looking for a 3 port BCS!

bdon22 19th Nov 2015

Easy install

Installed mine today... it was literally 3.75 times easier to install than I had imagined. Flashed a new map and the car feels smoother overall. I notice a lot less fluctuations in my boost gauge. Boost seems to come on quicker and is more stable overall. A+ product.

Grimmspeed Service Delivers

"First off: I install a new to me turbo on my car. Monster td04 with a much larger compressor wheel. Boost was all over the place and a pain to tune do to the complexity of the turbo and that I suck at tuning. Place call to grimmspeed and talk to rich. I explained my problem and asked if they had their bcs in stock. Of course backoredered. I beg and plead and he calls me back an hour later. They went to where the company that put the sticker on the solenoid is and pulled one out specific for me. Tells me they will overnight it to me and threw in a free t-shirt just because. Fast forward to last night. Install of solenoid was a cake walk. Hardest part was connecting the new hose to the outlet of the turbo. Silicone spray will help. About 20 minutes and it's ready. Load up my new map from matt at 555 motorsports and start the car. Took it for some runs and boost holds no problem. Hitting just shy of 22 pounds and holds to almost 19 at redline. No knock or anything. In short. Great part great business and great tuner!! "

steverx05 19th Nov 2015

Boost builds much quicker

"Got my BCS from the group buy and installed it last night. The install went very smooth (besides the rain starting like half way through the install) and the solenoid bolted right into the stock solenoid location perfectly. (I've got an 05 so I can't vouch for the other MY brackets, but I'm sure they work just as well.)I loaded up my new map and took her for a spin. I have to say I'm very impressed. Right away I could feel a difference in first and second gear, my car doesn't feel as laggy and boost builds a lot quicker. In the higher gears it's just as nice, boost comes on quick and stays rock solid. I'm still on the stock TD04 too...I can't even imagine how great this would be on a bigger turbo "

RexTexWagon 19th Nov 2015

Very clean install and amazing

Had a protune done by Kieth at www.awdtuning.com this saturday, and got one of those new Grimmspeed BCS put on. I must say its amazing! First its very small and compact, and while I didnt put it on, Kieth had it on there in a snap. Its a VERY clean install(Ill take pics when I get my camera back), and I love how it mounts to a bolt hole and is very quiet. Thanks to that little gem I hit 18lbs on my stock td04 in every gear. And 18lbs in 1st is just silly. And I spool so quick I dont know what turbo lag is!

5/5

martin gasiorowski 19th Nov 2015

Had my doubts...but delivered

i had my doubts when my tuner recommended this part but now this is my favorite mod. its like a whole new car. throttle response is amazing! i can actually hit my tageted boost in 1st and 2nd gear, which i couldnt before. i recomend this to anyone, regardless of their level of modification.
