The factory diverter valve uses a hard plastic plunger to seal against the turbo diverter outlet that is made out of aluminum. Hard plastic does not seal well against aluminum, so boost pressure is lost, causing slower boost buildup and loss of efficiency.

Use the Go Fast Bits diverter valve kit to replace the poor seal between the turbo and diverter. This allows for crisper throttle response, faster boost buildup, and the leaking of boost is eliminated.

The solenoid coil itself from the factory-fitted valve is great (the ECU opens it faster than any pneumatic valve so why replace it?), but the weak point however is the valve mechanism itself. So GFB's DV+ solves this problem by replacing just the valve parts with an anodised billet aluminium housing fitted with a brass piston machined to exacting tolerances.

The end result is sharper throttle response, lightning-fast valve actuation, and it will hold as much boost as you can throw at it.

  • Comes with photo step by step instructions.
  • Retains the factory solenoid coil for seamless integration.
  • Replaces plastic valve parts with metal for reliability and strength.
  • Direct-fit replacement.
  • No check engine lights, no issues with driving, does not change gas mileage, etc.
  • Exclusive "pilot-actuated" valve mechanism for rapid response at high boost.

    Please note: as of early 2024, GFB has replaced the red silicone flap on the brass plunger with a blue O ring design. Our photos on this webpage still show the red silicone flap.

    Below is a how to video on installing one of these on your 1.4L turbo.

    Note: The OEM intake system does not provide enough clearance for both the Go Fast Bits Diverter Valve AND the Forge or MPx Blow Off Plate to be stacked together. If you intend to use both of these products, you must first purchase an aftermarket intake to create enough space to do so.

    Any issues while using this along with the Forge BOP?

      No, the GFB will work fine with the Forge plate, and we even have a kit with both together, as well as the longer bolts to connect them together to the stock turbo.

    What are the HP and Torque gains if any?

    • customer service rep

      Many Dart owners that have tested the GFB report better response from the turbo, as less boost is lost due to the factory diverter poor sealing. We have not dyno tested, but wouldnt be suprised if we saw a few horsepower across the board of improvement.
  • Joe
    Will this product fit on the turbo with the Forge BOV plate, since it has "extended bolts"?
    1 Answer
    • customer service rep

      Yes, that is exactly what we are offering. The Forge by itself comes with new bolts but they are too short to use with the GFB, so we have special new bolts that allow you to use the Forge and the GFB together.
  • Cody
    If I already have the forge diverter plate does the go fast diverter connect to the forge ?
    1 Answer
    • customer service rep

      If you already have the Forge plate, then it will go in between the GFB and the turbo.
  • Luis M.
    Will using both DV+ and Forge plate cause any problems?
    1 Answer
    • customer service rep

      No, this combo will work great. The GFB will seal a lot better than the factory seal so you'll hold boost pressure, and build boost faster, and the Forge plate will sound like a blow off valve. Its a win win!
  • Mike
    If I have the forge BOV already will the screws with this GFB kit fit or do I have to buy extended screws as well?
    1 Answer
    • Customer Service Rep

      There are four sizes of bolts used in the Dart/Fiat 1.4 Turbo as far as the diverter goes.
      1) Stock (shortest)
      2) GFB (longer)
      3) MPx/Forge spacers (even longer)
      4) Our extended bolts for use with MPX/Forge Spacers and GFB (longest)

      The screws that come with the GFB kit are not long enough to use with the MPx/Forge spacers and you need to buy the extended bolts.
  • No forge plate
    If I were to purchase this and I don't have the forge plate, will I have to use the stock bolts?
    1 Answer

      If you want to use the GFB with no MPx/Forge spacer noisemaker, then you should just buy the GFB GoFastBits kit by itself, and without the longer bolts. We offer the GFB kit by itself, and with longer bolts.
