Cheers Chris - that was great you doing that.

I'm just trying to track down a stock setup. A guy in melbourne on these forums has the stock BOVs but not the piping...I'm wondering how hard that will be to get ...

Here you go, just took them for u now.

I have a POD filter on my car. Dont think it has any influence on the Blow off valve. The stock setup is just putting it on the stock pipe. Making sure the Plumb back pipe is connected and that the smaller pipe from the BOV to the Manifold is also connected. And it should be fine.

Seems like my car has the standard BOV still connected with all the hoses (doesn't appear to be tampered with)...plumbing back into just after the POD

How can this be. Do some people add a HKS while keeping the standard BOV there.

So I can just take the HKS BOV off?

Is the HKS doing most of the work?

Gee these are nice motors.

It would make sense using both bov's though as a means of utilising the designed in 'leak' of the standard bov for the purposes of keeping the idle working correctly for the standard ECU.

The point I'm not sure about is whether the standard bov would have been screwed really tight to stop the valve from opening.

Yeah it is Chris. Will get the digi out tommorrow and have a better look - but traced all plumbing from the standard BOV and there seems to be nothing disconnected ....

Wonder if this means I can just get that pipe that has the HKS on it and replace it..

Both can be connected. I got one friend with an R32 with a HKS one and a stock one connected. This is how it works for him. When he drives the car normally the stock BOV works normally and there isnt enough pressure to open the HKS one. When he full on floors it then the pressure is higher and then the HKS BOV vents the pressure. If everything is connected i dont see y it wouldnt work. look foward to the pics :(

      Yeah since those first 2 replies I actually went and put some 98 in it and tbf it's already doing much better than the 95 (which is weird and makes my inner tinfoil hat wearer think the 95 was a crap batch), getting 8ish around town. Again, wonder if it takes a while to stabilize if the fuel is changed a couple of times. I swear cars used to just either run "well" or "s**t* in my 20s, none of this fuel optimisation business haha

      R33 headlight relay conversion?

      By GTSBoy · Posted

      Any number of different ways. Have the coils draw sufficient current to provide contact wetting. Use different contacts in the switch, either by material or design, better suited to the low current drawn by a relay coil. Etc.

      Hmm, how does the R34 manage to have headlight relays then without getting excessive carbon buildup on the headlight switch contacts?

      Not R7R. Meant to type R&R, obviously enough.

      R33 headlight relay conversion?

      By GTSBoy · Posted

      Bugger "making it look stock". I put one conventional internally fused Hella relay behind each globe. I just pulled the plugs off the back of the globes and built new loom segments with male and female plug parts to match up to the original loom and the globe, and used the original power wires to each globe coming from the switch through the original loom plug to trigger the relays. Ran a big fat (also separately fused) power wire across the front of the car to feed all the relays. It's as ugly as f**k, but it is wedged down between the headlight and battery on the RHS and the airbox and headlight on the LHS, and no-one ever looks in my engine bay, and on the odd occasion that they do I simply give no f**ks for what they think. Fully reversible - not that you'd ever want to. For f**k's sake. It's a Skyline. They made million of the bloody things. We've been crashing them into roadside furniture for 30 years now. There is a negative side effect to putting relays on the headlights. The coil current is too little to properly clean the contacts in the switches and they get blacked up and you have to open them up every couple of years and clean them manually. I have 25 years of experience on this point.
