BOV installation

[Jimbo2000]

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.

??

this may be of no use to you what-so-ever, but then again, it might be.

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.

cool cheers man.

yeah actually putting it on isnt an issue, just wondering about the repurcussions (sp)

and thanks to swen too although it dosnt help

i figured the bit in there on how to "tune" it may have helped with the "backfire/stalling" issues you mentioned, but if not, and you cant get a spacific set of install instructions, look up your closest import workshop and see what they have to say....

thanx swen

ok, so i'm going to install it now, can take the stock one off no probs, but what do i do with the black piping that seems to lead back into the intake, just leave it as is or block it off?

James,

As far as i know it wont make too much difference whether u leave it open or not, but for the sake of keeping crap out i'd block it off.

If i'm wrong ppl please tell me.

cheers si

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.

thanks steve for the info.

how did you block the recirc pipe off, some sort of plug?, a wad of newspaper :crazy:

yeah always popped/backfired so that dosnt bother me as yes they do run rich and are supposed to

[R33Steve]

Mines blocked off using a solid cylindrical piece of metal which i shoved in the hose and then clamped.
