compression surge is not healthy unless u live in vic and drive a VL ? and go to bell st maccers

stock plumb back bov ftw!

LOLLz

but yeh,,stok bov's are shyt,,get a stocky r33 gtr one

You may wind up stalling it everytime you pull up at a roundabout or lights... but go for it.. i thought it was awesome fun when i first tried it... and refitting it costs nothing...

dunno if it will root ur turbo though after prolonged use...

??

I've found a stock BOV with the internal bleed hole made 50% smaller gives a great comprimise between sound and surge. Blocking it completely, surges too much in higher gears on the highway and makes tons of noise. Also try getting a pod, makes much more sound.

Yes it will after a while and you will get increased lag.

Correct, but if you have a bov set to loose then it can also cause stalling. If you have a bov and tighten the spring in it then it will only open on high pressure, so you can get flutter with only a small amount of boost. savvy?

bro, jus get an fmic. after i put one on my car it made a flutter on high boost..nothin special but makes for some funny times

If you don't have a fmic, or at less a highflow side mount and you have a t04e then you're crazy.

I was told that it will cause turbo damage over a period of time.

thanks boys thats awsome but i love that massive flutter sound i might look into it a bit more and get back to ya .

also without the bov . dose it matter that its externaly gated ?

if you no what i mean ?

cheers

Then don't use one, but it will cause damage over time. As for the BOV being externally gated....are you talking about the BOV or wastegate?? If you have a BOV venting to atmosphere then yes it is illegal. You can have an external gated turbo, which has a wastegate on exhaust manifold, to be legal that has to be plumbed back into your exhaust system further down.

I was told that it will cause turbo damage over a period of time.

yes.

I don't think you can win either way, best going with what drives you least crazy listening to over and over again.

I hear ya rob. I've been ''dosing'' for about 18months, and my mechanic has aswell for YONKS, with absolutely NO damage. So the whole argument about its 'fulleybadforurturbo'is BS.

I switch between bov and dosing. It just gets boring :P .

sorry about that i ment that the turbo is externialy gated and why is it that if you run a bov into atomo , its illegal ?

Anything that vents gases into the atmosphere is illegal.

Wategates are only legal if they plumb back into your exhaust (if it doesnt plumb back its called a screamer pipe and that makes it illegal)

Same goes for bov, If it is plumbed back into your pipe work its legal (if it doesnt plumb back into your pipe work and just releasles into the atmosphere it illegal)

Does that make sense ? ? ?

    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks  
    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
