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. ?

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
