Hey guys.

Thinking of getting BOV just so i can hear the stupid atmo noise.

Few questions.

WHat are the main differences between the Blitz DD, Greddy Type R and the Greddy Type RS?

As far as i can tell they're all atmo, DD can hold upto 1.2bar, type r = 100-400hp and type rs = 280-450hp

WHAT THE HELL HP is my skyling and are these figures from the flywheel or the wheels?

And what do these soundlike?

Can't find any sound clips... :(

Which one do you guys recommend?

And why are these so darn expensive?

Thankls

what skyline do you have? stock or modified?

search those bov in youtube and theres a few there you can watch

you might have stalling issues when you swap your stock to atmo bov

it's lightly modded.

Why would it stall if i have an atmo bov?

The stalling problem occurs on standard ECU's with the blow off valve venting to atmosphere instead of plumbing back in, ECU gets confused by and RPM drops stalling the car. I personally didn't have any problems like these but a lot of ppl do so just try your luck. Do a search on stalling for atmo bov and learn a bit more about it if you get to worried.

might just wait till i get the PFC and then tune it so it doesn't stall...

A PFC wont necessarily fix the problem, as its more to do with the AFM than the ECU. If you have to wind the spring pressure up, then it defeats the point of having an atmo BOV, why not just block it off and stick a pod on it and enjoy the backspin noise, as that what most people are after, although you will still have the stalling issues

winding the spring pressure still allows the bov to do it's job. When bought the spring tension is very low and will stall. Increasing the spring tension still gives you the sound that he wants without compressor surge which is what you want to avoid

i reckon the greddy rs is the best.. most expensive though! just make sure its tight enough so it doesnt leak at idle should be 'ok' but PFC will sort it out for sure.... but steal wheeled turbo and no bov = inviceable pidgin chopper... haha just get the rs me boy

My friend had a Blitz DD on his car, then bought a Greddy type S to put on. Took me for a drive in it, and it sounded identical. After about a month of use it started to make a little whistle half way through the blow off that sounded allright. So my point is they pretty much sound the same :)

      We have 2x Swifts and my plans for a Swift, unfortunately, do not extend to an intake and an exhaust. I've been having dirty thoughts about a 2.5L Suzi V6, AWD gearbag out of a suitable donor, rear floorpan graft to take the rear cradle from same, and either trumpets of evil or a small supercharger. If I'm going to make noise in a Swift, I want it to be anti-social, evil handling and rough. Probably need to be fully stripped inside, matt black paint, plastic windows, 7" wide wheels, big brakes, silly suspension, etc etc etc. I have no idea if any of the proposed driveline components could take the pain. But it would be a hoot finding out.

      Really, anyone modifying a car isn't being financially smart. We're doing it for the things we love. And honestly, a high revving, light, NA car is actually pretty darn fun. I used to have a Swift Sport, and I miss that thing as a daily, and yes, doing something like some intake and exhaust stuff would have made minimal gains, but would have bought an even bigger smile
