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 :)

      Certainly. It is probably broken under the wire style clamp. At least that one is easier to get at than the front one.   Sounds like it isn't a major leak, I'd start with backing off the the water feed and return banjos into the turbos half a turn then tightening properly. Hardlines can still crack over time, either in the tube (particularly when turbos are changed if the banjo is siezed in the the tube) or at the brazed joins between the lines and the banjo fittings. A coolant system pressure test will reveal all. BTW you'd be able to get a sump without exchange, it will just cost more as they will have to source another stock one for the next customer. If you want to address the sump a much better option is something like this https://www.hioctanedirect.com/hi-octane-racing-sump-extension-nissan-rb26 that you weld in locally (and add the oil return fittings at the same time)

      Pretty sure you are thinking of the throwout bearing there (which you should change when you change your clutch), when they are worn they will get quieter if you put your foot on the clutch. An input shaft bearing is turning/noisy at all times.

      I’ll have more of a look into Recaros over the weekend. It’s taken me 2 days to figure out which Bride seats suit my application haha.

      I am aware of their presence, but the product page looked like that conversion will eliminate the AWD capability. Fact remains it's kind of a hassle to send my oil sump halfway around the world and buying an extra one is expensive and unnecessary. Before I go hat route I'd explore more local options.    Would you recommend I just pull the engine and renew as many things as possible since I'm already having problems with some leaks? Would have to get an engine crane first though.

      Are there any indicators that the vehicle is in limp mode?  Any dash light, or something.  Or is it just lack of acceleration?
