i've ran 3 of the bOV's u listed. All i can say, dont go for HKS unless youre willing to sacrifice driveablility for sound because thats exactly what you're gonna be doing, makes ur car run like crap but sounds sweet. Forge-i dont like messing with springs/shims, headache. Greddy Type-S single spring modded still sounds nice and idles NICE! great bov. Crush-1G, i never tried it but i dont feel comfortable crushing a bov imo. i have the MR DV right now and im gonna go to the APS next if this doesnt work out.

 

If the JDM MR DV doesn't work out, let me know, because I'll buy it from you immediately.

 

i bought the Go Fast Bits Stealth FX bov and i am very happy with it. it has an adjustment spring to change how long the bov vents. also it is the best of both worlds you can vent as much air back into the intake track as you need to satisfy your maf sensor, or you can vent it all out to the atmoshpere. putting on the whistler trumpet attachment lets out a sick a ss whistle.
