AAAARRRRRGGHHHHHHHHHHHHHH

Just got my new Greddy BOV FV.

This came out of it.

Really rough inside, cut your finger easy.

Valve is very very hard to push in by hand, even when sucking on it.

Retainer ring on the bottom isn't gold.

Silicone tube doesn't have Greddy logo on it and is smaller OD.

You know what I'm getting at.

Seller more than happy to refund and pay for return postage.

Phew.

Ok Scotty, I'll wait for the tune mate.

is it a genuine Greddy? how much did you pay for that? at least, it should not cut your finger.

you need go for Greddy soft spring, plumb back adapter also. but you can't get rid of pigeon sound unless you tune the car.

I'm pretty sure it's a fake.

No way I'm fitting it with metal shards coming off.

Greddy website has a warning on the RS models.

This FV has all the same things wrong/ different as in the pictures.

Paid $97 including Nissan adapter plate.

Others are selling it for $360

Don't say it

Scott. What's your take on bov vs no bov for response and making boost?

I've tried a few, standard, blitz etc. and have found they all leak and in return partial to half throttle suffers.

The stock BOV with a grubscrew was ok, bit of hesitation as you come off boost to a cruise.

Once I changed to the Turbosmart Kompact plumback I never had an issue.

Personally I only use a BOV blanking for diagnosing faults, I would never block it off for any high boost runs, there is a good chance you will twist the turbine shaft or damage the compressor wheel.

We have run no BOV on all our non Borg Warner EFR equipped race cars with no adverse effects. Having said that I won't do it on my stag as the compressor stall sound is so loud it's embarrassing.

Blocking the OEM bleed hole makes surge worse but improves spool, so you have to make your choice.

Sounds like the Kompact is a good unit.

Oh, update on my 33gtr BOV. It improved surge due to a softer spring but it bleed air due to intake oscillations....which is what I expect causes the surge. I moved the BOV sense line to the fuel reg output further up the plenum which helped a little bit.

Running a modded Rb25 BOV atm. Seems the same as the M35

Thanks. I'm a bit worried about the turbo at high boost. But not willing to sacrifice my cruising response for it.

Are you using the normal one designed for Nissan not the dual port Scotty? I thought everyone was having issues due to it not being adjustable? Or did you get a softer spring or is it a non issue because yours is tuned?

Yes Phil, you can buy different springs for them, but I bolted mine straight on and it worked well out of the box. I guess the tune is compensated nicely, although I suspect it has a lot to do with the design of the 3 inch intake too and how the return is plumbed back in.

I couldn't decide which colour to go for so I've decided to keep both and twin turbo the VQ25DET

That should get rid of the shudder

Australias first twin turbo M35

They aren't turbos. ?

    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
    • @GTSBoy yeah sorry i know thery are known for colors bud those DBA are too in colors 🙂 Green will be good enough for me
