I'm a first time buyer of a turbo car (buying a R32 GTS-T) and am looking for a few beginning upgrades for my car. As a BOV seems to be one of the most popular upgrades for a turbo car I just want to make sure I buy the right one and be happy with it.

I would like to hopefully hear from some people about there experiences with there BOV's from the various dramas/problems they may have had or the satisfaction they got from it. From what I have read the HKS SSQ BOV seems to be the best but it is also bloody pricy. But with so many other manufactures such as GREDDY, Turbosmart and other brands there are so much to choose from. Also I would like to know the pro's/con's of plumback systems.

All comments would be greatly appreciated,

Cheers.

I heard the GFB (Go Fast Bits) range of BOV's are good. I run a Blitz BOV old type and i like it. Requires a bit of fiddling to get right....

I found i had to completely remove the stock bov, block off the hole and the return pipe and it worked a treat from there, just a few play's with the adjuistment screw..... and PCHHHHTT!!!

agree'd with the above 2, but when it comes to change the bov, i have the GFB Hybrid, which is really great, just got the adapter plate to where the stock one bolts on, and its part atmospheric and part plumback to help with the air/fuel ratios etc, and helps it not stall, without this, and not tuned of course the car was stalling every 2 seconds...

cheers...ben.

Is that the main reason the dual venting ( plumb/atmo ) BOVs were made for? For people with AFMs so they dont mess up stuff with the afm but still get to hear the atmo venting noise?

Or is there another benifit?

I am also in the market for a new BOV as I have a shitty plastic bosch one and its not coping with my boost levels.

I dont have an AFM so thats not an issue but I want a plumb back one and just wondered if there was any advantage in getting a dual port one or not?

I dont want to have an old lady scaring "PSSCCHHH"

A question though. Is the factory BOV capable of handling high boost levels or once it reaches a certain boost level it begins leaking air. Is there any real reason to buy a BOV rather than for PSCHHH!! sound? Or can the factory one cope with it well enough?

Yeah I am new to the GTR thing, but I modified my SR20 180SX to befairly hard. I have spoken to a friend who has owned a few GTR's, he said the same thing. I just wish I didn't live in the back blocks of nowhere so I could ask more of these questions...

At first I was thinking that the GTR BOV's would be like the stock S13 bypass valves. Then I realised I don't think I ahve seen too many GTR's with aftermarket BOV's..

generally speaking, unless your factory BOV is faulty, theres no real reason to change it, other than to get the sound you want. You can pick up cheap 2nd hand BOVs, if i were you id throw on a nice loud atmo BOV, as being new to the turbo scene, you'll love it :D then once your over the noise and attention, stick a nice sealing plumbback on it. You will still get a bit of sound if you run an exposed pod filter anyways.

sounds like your car is just a baby at the moment so i wouldnt be concerned about the stock bov handling big boost, because you wont be running big boost. You will more than likely be running around 1bar with basic exh/intake mods and a bleeder, that will be fine.

Yeah my car is basically unmodded and unchanged at the moment. I may have a bit of fun just running low boost and an atmo BOV at this point in time until I get used to the power of a faster car. I was planning to focus more on the handling of the car instead of just raw power. Just going to have fun at first while I build up a couple of ideas for the future :(

Mate, if i was still in Perth, i'd pat you on the back.

You've got a great attitude and approach to performace. Starting and working slowly is the ebst way. Rather than go making a 400w machine and not know how to use it.

      S1 rb25/s14 starting problem

      By Duncan · Posted

      Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
