Couldn't find air filters on their site?

found these: http://www.nengun.com/nismo/s-tune-sports-air-filter

Which is the correct part number? And How long do they last?

The K&N ones supposedly last 50k km???

Give them a call, they may have some in stock.

The Amsoil ones are guaranteed to last "100,000 miles or 4 years" - I have to back that as I am still using mine no probs :)

Re: Nismo air filter (from the RHD Japan website)

"The NISMO S-Tune Air Filter is a direct drop in replacement for your OEM unit and has a urethane/foam composition which will allow for the increased performance."

That fart sound from the stock blow off valve is embarassing. Especially if you've got chicks in the car :)

From outside they look at the car and it looks like it's new but little do they know when you boost a bit, it poos in it's pants.

hmm... I don't get any kind of noise from my factory BOV, even at 1.3 bar there are no such noises from the BOV

Turbo noise - but now I notice SOMETIMES (maybe 50%) when I hit boost, I get a "rubbing" noise - imagine driving over the rumble strips on the Hume, now speed it up x2. Sounds just like that...

Can you clarify whether the noise happens when you HIT boost or when you STEP OFF the accelerator whilst boosting?

I don't suggest it, mine holds 22 psi just fine. I drove Aarons with an aftermarket bov and wasn't impressed. Sorry Aaron. :)

Thanks Scott :)

lol yeh wouldnt recomend going after market. Regret it, and im lucky to have found a stock one (thats right scott! a stock one)

blocking it makes that "stuuu tuu tuu tu" sound. This will either snap the shaft in your turbo or shatter ceramic fan on the back of it. whichever is weaker, try to force exhaust fumes back into your engine, and do the ripple strip sound which is uncomfortable.

i had an atmo and needed to put the strongest spring i could get. our vacuum rate is much higher in our cars because they are electronically times, as compare to older cars. I did it just for kicks. found me kicking myself having to spend an arm and a leg repairing(hi flowing) a turbo.

because of the above reason, u could imagine why the stock would be the best.

OK - so basically my car's BOV is partially or fully blocked. Which means its stuffed and I need a stock replacement. You can't "clean" them, can you?

If I need a replacement - is it easier to get it from Japan? or order from Nissan Australia?

Something like this would be crap?

well i wouldnt suggest pulling them apart.

an idea? what im doing temporarily is using a Turbo Smart plumb back replacement for our car. it comes with a "green"(mid) tension spring. but its not soft enough.

Theyre "blue"(low) tensioned spring is the go. BOV should stay open at idle( which it does now) and should easily blow open when releasing throttle becuase of the softest spring. rated up to 600hp i think as well.. mine is still the green spring, and just BARELY making a beep sound. im not gonna get the blue spring because i found a stock. but I guess it would work. simple bolt on aswell. i think your looking at $200.00 RRP?

like i said ATMO isnt reccomended because of the Vacuum rate. Super sequential Valve by HKS is good but i wouldnt get it for ours, i tried one n my engine kept dying off throttle as the spring isnt strong enough. Probably wont fit under the BOV bracket aswell where as the TurboSmart Kompact fits just as a stck one.

oh n sorry for the long post's, I like to explain things in full

No problem - I like to get as much info as I can!

So I need to find a "blue" tensioned spring, which I take it is a stock part from Nissan?

I don't need the whole BOV assembly? Just this spring? Or I need this "Turbo Smart PLumb back" thing...? where do I get that?

Sorry for my newbness!!

haha nah its ok. im still newbing it i guess..

you'll have to replace the whole blow off valve. i dont think the stock ones come apart.

before you do replace it though speak to scott because i remember him saying something about a grub screw in the stock one that made it surge.(dont ask me)

but.

http://www.turbosmartonline.com/index.php?id=46 explains it. scroll down abit till you see the black ones.. its model specific for Nissan, including "stagea - all models" which is bull shit.. lol you will need a blue spring. which is like $15.00

Firstly, take the bov off and inspect it, Im guessing the hose is split or worse, there is some internal damage. There is probably a spare stockie floating about if you need one.

Our bov is special, it bypasses air all the time from a 4mm hole, this should not be blocked. (as I found the hard way) It helps eliminate compressor surge. Better would be to stick a solenoid on the bypass hole to block it at full throttle but as I said, I can hold good boost with it venting anyway.

  • 2 weeks later...

Hey Jethro, how is it going with the bov problem?

Sorted yet?

Keep me updated mate

I should be getting the turbosmart thing from Aaron later this week...will let you know.

I think I will also start hunting for a used one on IM or from Jesse Streeter. Hey what did you mean when u said the BOV smells like egg? Are you kidding?

You wouldn't think of repairing the factory one? Sometimes all they need is a bit of a clean out. Kero bath and actuate it a couple of times and then you should be right?

The only other thing I can recommend is looking for boost leaks (such as cracked or damaged tubing on the pressure side of the engine.

Regardless, keep us in the loop on how you go.

hey everyone i had a look at it. its definitely not the BOV. its kind of like a quick brdrdurur sound like scraping something rippled with your hand. the BOV is fine. all the pipes are tightened. Driving it kind of feels like when you release the accelerator and the car kind of jerks forward its rubbing something for a split second then calms down. i think it might have something to actually do with handling rather than engine.

definitely not surge. i even tightened all the pipes.. def not leaking, doesn't seem possible to leak only when coming off boost right?

any ideas to help Mr IronPaw out?

Yep gotta thank Aaron for having a look at the issue...he reseated the BOV and tighted all the hoses but the farting noise remains...grrrrrrrrr

Might need to visit you Scotty..,when you guys are done with Craig's car that is :blush:

Hmm I get the noise when I let the accelerator off when I'm at (full?) boost between 3-4.5k. Doesn't happen ALL the time but usually does (70%). Never happens above 5k...

Throttle butterfly ok? sounds like its surging but it wont with the stock bov, mine doesnt unless I block the bleed hole. Perhaps its blocked with gunk?

    • Nah. Was just wondering if you were having a small stroke or if there was some slur/gaf/inside joke that I wasn't aware of.
    • That was a fark up, it's Salamanca Place I was thinking of. And now I'm curious as to what potential slur/gaf I have caused with Salamander Road, ha ha!
    • Actually everyone on the roads was really well behaved. The only person that did any minor tailgating was a local hoon in a Turbo Focus. Unfortunately we weren't going the same way so there was no grand initial D touge battle. Lots of people pulled over and let me through. The amount of "Hey man nice car, omg skyline, nice 34 man woo" was suprising. Like really suprising. Like almost annoying. My partner was obviously surprised, she'd never seen anyone in the real world point out the car/like the car/want to chat about the car before, so to have like 3 people per day mention it was notable, I could finally say SEE? SOMEONE THINKS THEY'RE COOL. Everyone was also pretty suprised about the weather. Every day was dry and about ~13-14C. Mount Wellington had a sign that said they close the gates at 9pm and I was heading up there at about ~7:30. It was VERY apparent that conditions were getting significantly worse by the minute on the way up and down. The road on the mountain was terrible though, it's no driving road. I have various suspension related questions now. Luckily it was only about 20 minutes from where we were staying to the top of the mountain as said Google maps. We only had the 2 nights in Hobart. We went to the Farm Gate Market though which was really good - And went down to the Hastings Thermal springs/caves down there during the day. I'd definitely be up for going back again, so luckily there's a few more sights yet to see. Didn't get to do the west coast/queenstown/cradle mountain so this was supposed to be a 'scouting' trip anyway of sorts if I were to one day do/take part in/organize a more car-focused trip. As for the boat, it wasn't bad. Well it was bad, but not in the way you're thinking. We did the night trip which leaves at 6:45 (though you have to be there ~2 hours earlier) and arrives the next morning at about 6am. There is nothing to do on the ship. If you plan accordingly and bring a book/tablet/show to watch/charger you can just chill out, take some Travacalm and just sleep through it. The food there is an extremely basic buffet that costs $32 a plate, or $14 for a $3 pizza. The way back we had a travel kettle and a few different types of cup noodles and made our own tea/coffee in the room. This was a far superior way to do it. At the very least book one of the rooms with beds. I guess as we were in the off season we didn't have room mates. You get an option for rooms with 4 beds (2x bunks) or a room with just the two bottom beds. There's also some option for a deluxe queen bed but it's much pricer. We've been on sleeper trains in Asia before so we figured this is similar (and it was)
    • You just gotta be really, really, really clear and decisive with what you want your end product to be. 99% of people who want this conversion aren't "I want to run a 295 front tyre!" so they don't really need the widebody. They just want the OEM body to look a little less dumpy, so bonnet, bar, skirts job done with some camber, stretch, slam. It's when you want that, but then decide to pivot later you get big problems. See also if you're willing to get an all in one fibreglass bar, and you're willing to accept fibreglass problems like cracking the entire item on a driveway, instead of just a piece attached to the bottom, etc etc etc. Decide this all before buyin'.
