Features & Product Details

The Grimmspeed 3-Port Electronic Boost Solenoid has been a treasure to the turbocharged world of sport compact drivers. one of their best selling items here at RallySport Direct is their easy to use 3-port Electronic Boost Control Solenoid. This particular boost control solenoid will allow the use 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. 

Grimmspeed also made it a point to use ultra-low profile hose fittings to keep the unit as small and compact as possible. The hose fittings are made of nickel plated brass so you don't have to worry about breaking the factory plastic hose fittings.  

Full features include:

•    Direct plug and play into 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 factory location
•    Low-profile brass hose fittings (small in size so its compact)
•    Specifically designed by GrimmSpeed to work safely with the factory Subaru ECU (requires tuning) and to reliably handle the vibrations and temperatures on 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 easily can be returned back to stock
•    Allows you to raise the factory boost levels with adding more response and more control
•    Allows you to get to full boost sooner
•    Faster response and greater flow than any other valve out there. (By more than 10%)
•    Nickel plated brass fittings


* Allows you to raise the factory boost levels with adding more response and more control.
* Allows you to get full boost sooner.
* Faster response and greater flow than any other valve out there. (by more than 10%!)
* Nickel plated brass fittings. (unlike the competitors' failure prone plastic fittings)

I was torn between this and a Cobb boost controller for my 07 WRX. I got this because of my tuner's preference. The car needed tuning to use this, but I got injectors at the same time, and so it was and I'm happy. I would buy this again. As a note, Cobb and Grimmspeed are both vendors I have used before and that I would recommend.

My 2006 STI needed to be pro tuned so I decided to get an aftermarket EBCS. I really like Grimmspeed products so I decided to go with their EBCS. I was not disappointed. Quality is amazing as always and with the instruction video that they make for all their products, it was easy to install. The only thing I wish they would do different is provide silicone vacuum tubing. It does come with plan rubber vacuum tubing though. I changed out all my vacuum lines with Turbo Smart tubing while I was in there.

I decided to get my car pro tuned so I bought the Grimmspeed BCS to go along with it. It works great! Part is awesome quality as always with Grimmspeed, I just wish it came with silicone vac line instead of just rubber line. Other than that I love it. Easy install too!

When I bought my car it already had the grimmspeed ebc installed but it started having trouble so I replaced it with the same one so I wouldn't have to retune.....Seems fine so far.

QUESTIONS & ANSWERS

  • Q: Grimmspeed 3 port ebc  04BlobEyeSTi12 days ago

    I think my GS ebc solenoid crapped out on me.. if this was to happen and I replace it with the same GS 3 port would I need retune? I've heard it would have the same tune I had since it's the same brand/model boost controller
    • 0 of 0 people found the following answer helpful

      A:  If it is the same exact boost controller and you can set it to the same exact parameters you would not need to retune.

  • Q: Will this work on a JDM Subaru Forester?  hydn796 months ago

    I'm located in Japan. I have a 2006 JDM Forester. The motor isn't 2.5L like the US. It's smaller 2.0 (ej205). Will this work? I was told COBB access port won't work with JDM so curious is this also conflicts with JDM ECU?
    • 0 of 0 people found the following answer helpful

      A:  Unfortunately, we are only able to confirm fitment for USDM vehicles/ECUs. I would recommend checking with your tuner to see what options would work for your FXT.

  • Q: Safe to use before a tune  Forester XToby7 months ago

    I'm getting my car tuned in a week, I know it's recommended to get the boost solenoid tuned but my question is this. is it safe to install the solenoid and drive around for a week then get the car tuned or would it be better to install it in the car park of the tuning place then get it tuned right away(I really don't want to do that).
    • 0 of 0 people found the following answer helpful

      A:  You would want to install it in the parking lot at your tuner's shop. Driving un-tuned on an aftermarket BCS can cause serious engine damage. However, your tuner may be able to send you a base map for you to flash at home so you can safely drive to their shop.

  • Q: Fitment  steezytricks1011 year ago

    Ok I have an 06 sti. My buddy gave me his grimspeed ebcs off his 02 wrx. Will this work on my car? I have read the other questions which were similar questions just reversed and you guys said it would work but I would just like to double check and make sure before I try to instal. Thanks
    • 0 of 0 people found the following answer helpful

      A:  They are the same but the one for the STI will have a few extra grommets for the bracket. Other than that, it will work fine.

  • Q: Electronic boost control   Specter 1 year ago

    Is this the same as the Grimm speed 3 post electronic boost controller?
    • 0 of 0 people found the following answer helpful

      A:  This is a 3 port solenoid, if you are seeing multiple options, please make sure you are using the vehicle filter so the correct one for your car is selected.
