but they sit open at idle (sucking in air AFTER the afm) so you can't vent them directly to atmosphere (learnt that the hard way)... they suck air in at idle causing stalling and rough as guts idle.

mine had an adapter kit put on them from the previous owner in japan. they vent to atmo and cant suck in any air :cheers:

so you just wanted sound?

anyway,

shaqrx3 - factory bovs are probably the best setup you will get.

but if you must upgrade and want sound, the single greddy type R is fine. it is huge and it will flow more than you will ever make..

Let me know when you want to sell your stock ones.

yes they sit open at idle, which makes tunning a hell of alot easyer.

ask any one that tunes gtrs with AFM's. if you have bigger than stock turbos or BB turbos its hard to get the idle right with an aftermarked BOV.

i had that problem when i got the new turbos on mine, they couldnt get the idle right, because the BB turbos are still spinning damm quick after a bit of wide open throttle.

i also see it as helping the turbos as well, the plumb back system flows air after the intercooler back into the intake. so its breathing in cooler air :)

just my 2c anyway.

anyone know where i can get stockies? ive got blitz one and theyre huge...but then again the BOVs are placed where most cops wouldn't look

They pop up every now and then when rice.. err.. people replace the stockers with aftermarket ones. Just keep an eye on the forsale section.

True, but given the prices on NS (as low as $150 for a "hybrid" copy FMIC) I doubt there is going to be many used ones much lower on here :D

      Well, this is probably where a wiring diagram and a multimeter come into play.

      gauge needle removal

      I can say to anyone thats doing this; having done a number of R clusters; just be careful if its an unknown cluster.  It takes a bit of force to pull up; but if it feels excessive then its probably stuck. I've had this and pulled the entire hair spring out; and I can tell you; its not easy getting the correct spring replacement with the correct inner diameter and winding. In my case someone had used some sort of adhesive to stick it to the spindle and it pulled the whole spindle out; which the force seperated the hairspring from the spindal and caused it to deform.  You may have to clean it (IPA); or in my case if i'd known i should have used some sort of solvent on it.  Also check out Cruizin Central on eBay. He does all sorts of dials; and you can email him with any custom designs you want. So if you want like certain logos etc...he'll send you a mock of what it will look like then you accept the order and he'll take care of the rest. Fantastic dials and he can do basically any design you want.

      R33 GTST Axles

      Have you confirmed its the actual axles? Also the wheel bearings that mount on the hubs to hold the axles wear out. I replaced mine as they got play in them. It sorted my play issue.

      R34 Speedo not working after manual swap

      By Jarsky · Posted

      Ive converted a few clusters for the R33 with 320km/h dials. On the back there are some pads which can be bridged or unbridged (using solder or wick braid) to calibrate it. There is one bridge which is for MPH <> KPH; and there are combinations of bridges to offset it. There is probably a diagram  For example; this is my conversion for a 180km/h dial to a 320km/h dial (I put custom GT-R dials on it with the GTS25t layout) If you have J2 soldered (assuming the S clusters have a similar config to the R clusters); you may need to remove that solder

      Back on topic 😉, these are some of the notable pages from the booklets that are supplied with each weekly parts update. I never knew the BNR32 test mule car had an S13 Silvia front end... *Edit: On closer inspection the test car still had the R32 body, but only the front end had Silvia panels etc.
