s13silvia

dear lord that's horrible haha

Just spotted this- seems quite interesting, can't picture how it'd look on the z though.

nah cuz that's clear cut.. white, midnight purple, bayside blue and yellow all have even grounding.. the others are crap :lol:

I'm pretty sure the Bluebird SR20 SSS's didn't have them either. The recirc valve will lengthen the lifespan of a turbo marginally yes - that doesn't mean that not running one will suddenly limit your turbo to 2k miles. It may last 80-90k instead of 100k before needing servicing. But as for performance issues - poppycock :D

The 1.8t s13? the 2.0 6-cyle turbo Laurels, cefiro's? none of them had bov's into the 90's.

LOL nothing more than internet heresay, if .. and I say if, it is the case it makes a difference for a fraction of a second and is not noticeable. I'd be happy to dyno it to prove it if somebody was willing to spend the money. I'll agree there may be a risk to the turbo's, but it's slight. Again, I've had turbo cars with no bov's recirc or otherwise fitted since the factory run huge mileage. Me taking off a blow off valve isn't going to sh*t a turbo in less than 10k miles unless it was going to sh*t it by then anyway due to mileage. :) I'm quite sure Baz will agree with me here if he ran this setup on his GTiR, the difference in performance is negligible. I've been in plenty cars with this setup as well which were run very hard - nobody's reported any issues with it. As for it being chavvy - it's no worse than an atmos BOV, and is a damned sight less money wasted, with the advantage being it wont leak at higher boost levels which factory nissan recircs are reasonably prone to doing. But it won't be as smooth during gearchanges or easing off the throttle. No need to pounce on me guys, I was just testing it out :helpsmilie:

There's none, a recirc valve cannot increase performance over not running a bov. :yes:

Yeah just glad I gave it a shot as lots of people seem to mention it ... then never go ahead. I mean it is audible, and some people may like it, but it's nowhere near as loud as you'll hear on some other engines - point your peepers to holden VL's or evo's and you'll hear the sound I was hoping to achieve.. but didn't ;) live and learn eh :D

Would they like an incredibly filthy bashed up Z in burgundy with black wheels haha :D give me 6 months and a payrise and I'll bring along an awesome Z ;) Good luck finding one though :0D

Blank up everything and tsshh tsh tsh is heard :yes: but on a z32 due to the t25's and piping and distance of air filter you cant hear it very well in the cabin. The tscch scch sound is down to the air going back through the turbo blades as written above - damage is an unknown, though it may well cause an issue in 1k miles, or 80k miles nobody knows - at the end of the day I've had a 200k mile CA18det which had a closed system and the turbo still pulled strongly. The recirc bov is not only there to relieve pressure, it is there to make for a smoother ride and less noise. Atmos BOV's are a bit louder as the air escapes the system in a quicker fashion, but it makes a different noise depending on if it has any specialized valves/fins on them. I haven't fit one on the Z32 though I may do so because it will be a bit louder and I'll admit I for one like the noise they make. On some cars, like an S14 or an evo doing the bov-less thing results in a wicked noise which is easily heard even on stock boost :yes:

Well I'm sure im not the only person who's mind this has run through as it's quite a common modification on other turbo marques. For those considering running this setup on a 300zx it's essentially the same as on any other turbo car, use 4xblanking plugs - 2x35mm 2x27mm and get some nice new jub clips and sealant (loctite etc) whilst you're at it! Take off the standard recirc valves, plug in the blanking plugs and then stuff bolts in the redundant vaccum pipes. :thumbup1: (obv you will need a pod filter to hear anything) Now I'm going to tell you it's not worth it on a Z. Possibly due to the turbo size/ piping, or the distance of the airfilter from the cabin, you won't get much of a noise. Yes it's audible when surrounded by walls etc. and makes that nice 'tshh shh shh' sound, but it's not loud enough to be appreciated on stock boost. Driveability wise, it's no different to running an atmos BOV. Occasional lumpyness, and its not as smooth between gear changes as the recircs. So far I havent had my turbo's blow out the side of the wheel arch, or compressor wheels slicing through the car as advised by the nay-sayers :tongue_smilie: I just agree now that it's not a worthwhile mod. Once im running more boost I'll see if its much louder, if not I'll probably revert to the recircs or go for atmos BOV's. Thats my experience so far anyway :biggrin:

I've heard lots about you from .. well everybody! Seems as though you are the man in the know with ecu chipping. Hope this is within forum rules but could you please email me about your services? Im looking to have my ECU chipped so I can run 15psi on an otherwise stock-ish engine (intake exhaust the usual entry level crap). But I'd like to ideally post my ecu down and have it soldered in as I'm crap with a soldering iron! I've emailed the few companies in the uk that I can find and nobody gets back to me. My email is dlongmu@hotmail.com Many thanks! David

tbh I can't say I like professors at all. Never found that design appealing

Newera parts mate :) Theres a few other companies too.. i was gunna go for a set of XD9's was looking around 1400 new imported which isnt too bad

A bolt pretty much works everytime :)

280 hp for the win haha :tt2:

WHAT.. clearly i misunderstood the forms =[ These guys must be smart in some ways to wangle 100 tax-free spendy-quids out each week and still be homed bathed (assuming that applies) and heated!!

Well.. for 4 :p which is about right, 4 pounds or so per bung .. I've seen people charge a lot more :) Hehe but yes you probs right - good thinking on the chair bung front :D

Check out GEX performance! On google and ebay, they have the cheapest priced alloy bungs available in 28mm and 34mm! I've just bought 2 of each and it was 25 pounds posted :)

I was on the dole for 10 months after graduating.. it was sh*t. Don't get me wrong, I wanted to work desperately but due to my location maybe 2 new jobs came up a week. There were jobs requiring relevant degrees paying minimum wage etc. because they knew they'd probably get the best they could for little pay in desparate times :( The worst bit was I was working for more money before my degree than I've been able to make after. After 10 months I got a job shovelling grain and heavy machine maintenance for 100 hours a week on night shift for min. wage (no overtime). But after 2 months I just couldn't cope any more as it was seriously draining hard work. Now I've got a job in an IT centre doing close to network engineer-stuff (no jokes, not bumping myself up here, theres 4 of us serving the european and middle eastern divisions hill and knowlton who are a global PR company in everything from exchange/AD issues through to VPN problems, graphic design etc.) and theres some seriously intense and up-to-date IT research needed each week and I was already very well versed in IT from a young age. I'm on 13k PA which is sh*te. BUT I might point out that 13k is a lot more than jobseekers! Never mind the fact it doesn't do much for ones self esteem. I don't know how I survived on it for 10 months. My question is this: If they are earning 45 pounds a week, how much are you charging rent, and how do they pay bills and food ontop?? I can't feesibly see how it would work unless they are scamming it

at least it proves it works :) nice job man

Ah shit yeh gotcha - seen a few Z's running this setup on youtube suppose it removes the chance of any leaks in the stock recirc hoses too :cool2:

If you leave your Recircs in with no vaccum hose ontop then they wont function.. It's the vaccum created by these that helps them function correctly im pretty sure. to be honest you're aswell of just installing the BOV's and ridding the recircs entirely if running atmos BOV's. If not, get some uprated recircs to fit in the stock location.

oh and many thanks for those sizes Jimmy!!

check the intercoolers too dude - can often be the cause of a leak, but then cracks in an IC usually wouldnt allow you to boost up to 17psi, maybe you are maxing their capacity at that... lol why do you want more than 17psi anyway :p
