Had one installed prior on first fbo build, replaced with a same but new solenoid after hearing that i was getting zero controlled pressure and it is functioning like it normally should with this new tune. Good product but id be wary when cleaning engine bay compartment to not let any sensors (in general) to not get soak or contact with any liquids. I believe thats what cause my old solenoid to short out. I have a ewg setup with fbo and tune running 450+ with this replacement ebcs. Tuner recommended
EJ205 20G Turbo EWG
My second Subaru I’ve installed a Grimmspeed EBC. Must have in my opinion. Great boost control and faster spool up you can’t go wrong there
Quality boos controller. Very easy to install. However, I did not see a "10% faster spool time" that is claimed in the quick specs section. My turbo actually spools slightly slower than when I had my stock boost controller. 2002 Subaru WRX with FP 71HTA turbo.
easy install solid controller
Great product had it installed in under 20 minutes! Allowed my tuner to lock in 20 psi for my stage 3 bugeye. Does what it's intended to. Recommended
dollar for dollar amazing product!
im soo happy i bought the EBCS from GrimmSpeed! Top quality, wasn't hard to install and rock solid boost! now im a loyal customer/fan!
EBCS - Awesome!
Got the EBCS very quickly from GS, install was easy, car made 300 easy with steady and precise boost control!
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.
A Must By!
Really locked down my boost! Peaked where I wanted it to. Allowed tuner to fine line everything as far as turbo!
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 for ver5-6 STI as well!!
Very excited to say that this product was 100% compatible with my version 6 sti engine!! Fit perfectly onto the jdm bracket and plugged directly into the harness. Works flawless, very happy customer!!
Easy to install, easy to tune, fixed my boost issue
Only took a couple of minutes to install and help my boost issues. Grimmspeed never disappoints
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.
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!
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
Quick and easy
Quick and easy install, very precise boost control (with a professional tune), and excellent customer service. I would definitely recommend this and GrimmSpeed to anyone.
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
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."
this is the best mod i have ever done. drives like a whole new car. i recommend this for anyone. not anyone looking to [insert what people are looking to do]. i meany anyone. this should be the first mod you do.
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 (Matt@555 Motorsports) adjust for it. It is way better than my GM BCS. I would recommend it to anyone looking for a 3 port BCS!
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.
Plug and play
"I love my 3port. Matt from 555 was the one that recommended it. He also tuned my car and it came out great!
+1 grimmspeed for plug and play quality!"
Tuning super easy
very happy with this 3 port bcs. Made tuning very easy
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!! "
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 "
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!
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.
Spool is great!
My tuner recommended me gettin one and wow, he was right. quick spool, easy install. got me a big 16g, tbe, up/down pipe, cai, tmic, etc...stage 4 = fun. big 16g, tbe, up/down pipe, cai, tmic, etc... with grimmspeed 3-EBC = lets do this!!!!!
Boost is ridiculous!
I bought one second hand off of NASIOC. WOW is all I can say. I have a vf39 and it spools so fast now its ridiculous. Love plug and play and great construction.
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!
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.
