hey..

recently got my hands on a hks ssq rice off valve.

i want to install it myself but i've heard that its best to get it done by someone who can actually tune it to work efficiently (PFC) instead of causing backfire/stalling issues.

is this also true with the ssq as i've also read something or other about how its different to most bov's and dosnt leak and so on.

??

hey man the installation of the BOV is soo easy that it is not funny. Do u have the r33 Flange? If you do then its a 15min job. Yes it is true, the HKS blow of valve will not leak under any ammount of pressure. This is because it is the only pulley-type blow off valve which is emune to this.

that black pipe is your recirculation pipe, goes back into the air intake just before the turbo. You can just block that off. With the stalling you should not have a problem if the spring is set tight enough. If its too loose the piston will not close before the throttle and you will stall. If you can see the piston from the outside of the BOV, rip the throttle so the BOV goes off and watch the piston on it. The piston should be completely closed about a second before idle.

Do you have an exhaust? if so you will prolly get backfire not matter who fits it. From what i have heard/been told the skylines run a bit rich from the factory causing backfire and an exhaust will act as a bit of a microphone for that :) I had a BOV before exhaust and did not get b/fire, put an exhaust on and got it. Sorry bout the length.

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before

      OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:

      R34 manual conversion speed signal wire finding, need help

      By GTSBoy · Posted

      Yes. Autos typically work from the speed sensor on the pinion shaft of the diff. I also think that even if you have a proper speed sensor for the bog manual in the manual box, that the signal it outputs is not compatible with the auto dash anyway. You should consult that manual (the book, not the gearbox).

      And I just realised that that advice is slightly nonsensical for a GTR, because you need 2 of them. But it is otherwise true.

      Duncan's V37.......race car?

      By Duncan · Posted

      Having had a reasonable look at the car, I'll be able to remove the (one time) rams and retract the hinge (they are held in the down location by a tiny (m3?) sacrificial screw) which will get it physically back in shape. From there if you remove the rams you need a resistor to turn off the airbag light (as Mark said, there are plug in kits and I might go that way because its reversible). And...per all the threads on here, even if you have the resistors to turn off the airbag light, the bonnet light will stay on as it writes to the airbag computer history - that is either replace the airbag controller, reprogam the EPROM (if I can work out how), or remove the globe from the dash. Having seen how sensitive this system is, if I had my time over I'd pre-emptively remove the rams, even on a road car, because this is all a very unnecessary pain in the arse. Reminds me, time to go and have a look at the Fuga too....
