Looking to upgrade my EVO 10 stock bov.

best option to replace ? not VTa

 

Keep the stocker... if not tial.

 

Dont really need to upgrade it unless its leaking boost. If it is you can likely crush it like the evo 9 and it will hold more boost.

If you really wana buy one a synapse engineering works well and supposedly tested to like 150 psi.

 

The go fast bits or GFB one is nice. Holds boost well, has different trumpet attachments, and is adjustable where you can go from recirculation to vta or anywhere in between.

 

TurboSmart-direct bolt-on

 

synapse DV works great for me. I'm running 34psi on it and no problems.

 

Tial QRJ with 1.5psi spring is the best bov I have used in the twenty plus years of modifying turbocharged vehicles.
