Features & Product Details

RallySport Direct proudly carries a great selection of quality aftermarket performance products brought to you by GrimmSpeed. 

 

This is the Grimmspeed 3-Port Electronic Boost Solenoid. This is one of their best-selling items here at RallySport Direct due to the simplicity of use along with the performance and reliability it provides. This particular boost control solenoid will allow the user to raise the OEM boost levels in a quick and efficient manner. Trying to raise the boost on the weak OEM solenoid can become unpredictable because of its inability to maintain proper and safe boost levels. By using the Grimmspeed unit you are able to improve boost response while maintaining a solid and consistent boost level. And it's also super durable as Griommspeed has crafted this solenoid to withstand 120psi which is much more than your engine will be able to see. 

One of the greater aspects of this boost control solenoid is that Grimmspeed designed these to have model-specific brackets, as well as OEM connectors. This means that you can bolt the bracket right up to the factory solenoid provision and plug it right into the factory plug to be a direct fitment plug and play unit. this eliminates the need for wire splicing or using zip-ties that could potentially create a visual eyesore in the engine bay. 

 

 

 

DETAILS:

  • Direct plug and play into the OEM wiring
  • MAC completely custom made valve
  • Users can use AN fittings with the solenoid
  • Mounting bracket so it's a direct bolt-on into the factory location
  • Low-profile brass hose fittings (small in size so it is compact)
  • Specifically designed by GrimmSpeed to work safely with the factory Subaru ECU (requires tuning) and to reliably handle the vibrations and temperatures of your engine bay
  • The only direct bolt-in design for all Subaru models   
  • Direct bolt-in mounting bracket and hardware included
  • Includes plug and play harness, no wire splicing required, and easy to return to stock
  • Allows you to raise the factory boost levels by adding more response and more control
  • Allows you to reach full boost sooner
  • Faster response and greater flow than any other valve out there (by more than 10%)
  • Nickel-plated brass fittings

    Easiest install to date.  3 years ago
    5out of 5stars

    I installed this on my 07 LGT so if you have a wrx your mount may he slightly different but it's still just 1 nut to deal with. I followed the grimmspeed install video from their site which you can easily find on YouTube as well. Routing was quite simple, even for my ewg setup as they supply plenty of vacuum line for the job. I did however have an issue with fitting the line over the nipple on my wastegate but I had some spare silicone hose and clamps at home so I wouldn't even consider that a setback. DO NOT IGNORE THE HEEDS TO GET A TUNE AFTER INSTALL. I had my tuner fashion me one well before I my parts arrived in the mail.

    Great performance for value 4 years ago
    5out of 5stars

    I like this little thing. Wasn't too difficult to install, and I'm seeing fast but safe spool up on my ported VF52 turbo combined with the Grimmspeed topmount intercooler. Previously, when all I had was a cold air intake, downpipe, and stock topmount, my turbo would make its presence known by a steady whooshing noise. Now, I hear this awesome fluttering sound as I build boost. Almost sounds like a quieter version of an external wastegate. Datalogs show everything is working fine on the turbo. Great product, highly recommend!

    Grimmspeed has never let me down, another quality part the functions perfect. Don't buy unless you're ready for a protune as you will overboost.

    GS 3 port ebcs 06 legacy gt 5 years ago
    4out of 5stars

    Bought this in conjunction with Cobb accessport, feels like a quality part and comes with everything youll need. install, with some really tight spaces and stubborn vacuum lines, took me about 2 hours. Overboost on any map is an understatement, NEED a proper tune with this mod. all in all another great grimmspeed part, worth the money for solid boost levels.

    QUESTIONS & ANSWERS

    • Q: EBCS fitment  znelson563 years ago

      So I have an 05 OBXT but it has an ej257 from an sti, will I need this one or the one for 04+ sti? Still running factory outback ecu.
    • Q: Boost controller  Subieboy123 years ago

      Can I use this boost controller solenoid in conjunction with the grimmspeed manual boost controller?
      • 0 of 0 people found the following answer helpful

        A:  This would replace the manual boost controller. In theory you could run both but it is highly not recommended.

    • Q: Mounting placement  LGTMATT3 years ago

      I have an 07 LGT, I do not have my engine cover on anymore due to the little bit of eye candy I've been installing. I am not a fan of the mounting position for the Legacy, would I run into any problems if I bought the WRX version and mounted the bcs on top of my bracket?
      • 0 of 0 people found the following answer helpful

        A:  The Boost controller will work for both Legacy's from 2005 -09 and WRX 's from 2010-2014.

    • Q: Replacing my COBB 3 Port EBCS  turbocreep4 years ago

      I'm currently pro tuned with the cobb ebcs and running stage 3 w/ an ewg. Will i need a re tune or can i just reset the ecu after swapping in the GS Ebcs?
      • 0 of 0 people found the following answer helpful

        A:  It is heavily recommended but we cannot say for sure. I would consult your tuner to be safe but you should be fine.
