yes you need one. without it you are likely to get compressor surge which can be very damaging to the seals etc of the turbo.

atleast pickup a cheap bov from a junkyard or something. aslong as it functions properly.
1g dsm's are popular.... i've got one

when you let off the throttle, the turbo is still spooling, that pressure has to escape somewhere, so yes you do need a BOV.

Yes, you need one unless you want to blow your turbo. If you don't want the noise, recirculate it back into the intake system before the turbo. There are a few aftermarket BOV's (like the Greddy Type S) that have special ports to allow for this.

It is "possible" to run a turbo without a BOV however I dont reccomended it for anything over 5psi as it will cause surge and eventually lead to an early rebuild/repair of the turbo.

No idea, I've never worked with a turbo diesel. The whole "no sparkplug" thing really bothers me.

have you never took off from a light with a semi truck in the lane next to you and tried to time your shifts with his so it sounds like your car has a bov? :chuckles: alot of semi trucks/turbo diesels have BOVs,..and they are loud too
