Hey guys, I have a strange issue with my RB25DET. It seems to have a weird fluttering/wooshing sound when coming on boost, a lot louder than normal. It seems to build and hold boost ok, maybe a little laggier than usual. I'm thinking maybe a boost leak, but here's the spanner in the works: the weird wooshing sound disappears during medium-hard left turns?? How weird is that? Does anyone know what could cause this issue and why it disappears during left turns only??? Any help appreciated. Thanks.

Hi everyone, my car is making a weird noise after I turn it on from cold or shut it off warm. This leads me to believe it's and exhaust component of somebody expanding and contracting but please let me know what you think. Thanks Vid: https://youtu.be/4YONIj38dto

Hi guys, I don't drive my R33 GTR often but this morning started noticing that my car's RPM gauge (stock factory) is acting funny in the sense that it would sometimes get stuck at 5,000 RPM and then not rev over that and then come back down again and then sometimes it spins up and down a few times and resets to 0 again. I don't think it's a mechanical or engine issue and my car drives normally but perhaps it something to do with the gauge or the wiring itself? Has anyone experienced this and how did you fix it? Thought I'd check here first before taking it to a motor mechanic. Cheers, Alex

Greetings at you all. Recentlyish I put a GTR BOV on my R33 GTS-t sedan just for fun and perhaps a little more Bov noise. All was good for a day or so, then it started doing the weird fart noise at about zero psi. I thought it may have been because I did the small hose inside a larger hose trick, so I got a 38mm - 28mm reducing style hose and put that on but it still does it. So I made up a plate from some aluminium sheet and drilled some smallish holes in it to use as a gasket, thinking that the reduced flow to the plunger might help. It gave me the flutters, so I made the holes bigger and back came the fart noise again. If I block off the bleed hole on the outside of the BOV will this fix it? That is the next thing I was going to try. I have tried a different GTR BOV and it still farts at the same zero psi and put my GTS-t Bov back on and the farts stopped. Yes the GTR spring is softer than the GTS-t and I guess the GTS-t bov leaks back into the piping but the GTR leaks out. The car may even be more responsive with the GTS-t bov on? Knowing that many people have used GTR bovs on GTS-t's and that this fart issue has come up before (as I have searched heavily but found no fixes). I am at a loss and am wondering if there is a reason it happens and a way to stop it. If all else fails, I'll just use my GTS-t Bov again. No big issue. In case it matters, I have K&N panel filter, silicon intake pipe, Stock Turbo, 10psi actuator, R34 smic, gutted cat and 3" catback blitz exhaust. Any wisdom is much appreciated. TL;DR ??? Why does a GTR BOV on a GTS-t Fart? How can the flatulence be stopped? Rob.
