what BOV are you running?
what BOV are you running? how do you like it? how do you have it set up(re-circ, atmospheric, etc)? just curious cause finally got a hold a an avenir motor.

Congrats on the Avenir .

I'm running a stock W10/W11 BOV, it gets the job done, but good luck finding a flange for it prewelded on the pipe. Though the stock W10/W11 BOV has similar flange to the DSM First Gen.

A little ago I bought a Greddy type BOV from SiliconIntakes.com, haven't installed yet but will soon. I need to tighten the spring for now, otherwise it might leak.

Greddy Type R on the S14 and a Tail 50mm on the other car.

Stock 1G DSM BOV on mine. Vented to atmosphere right now until I get it recirculated.
It was my 1st choice because it is the best performance per dollar, and I didn't need anything with a higher flow. It will hold 18 psi unmodified, and can hold unlimited boost modified.

Also have extensive experience with the 50mm Tial BOV. I love these, but would likely get the recirculation version for personal use.
Again, extensive experience with the typical Bosche diverter valve. If you don't need to flow a lot of air and are recirculating, it's hard to beat this thing.

Synapse Engineering Synchronic BOV. BAD mamma jamma.

Going to ditch my 44mm TiAL wastegate in favor of a Synapse unit, too. (Their wastegate has a boost controller built into the tophat.) Another reason to consider: They pulled a 50mm TiAL wastegate off of a test car, slapped on their Synapse unit, and at LESS boost, made +20whp at redline. Dyno sheets comparing multiple variables all showed consistant increases in power with less boost.

Sorry /offtopic.
