Wats up every 1 just bought a r33 gtst s1 ive been looking through the files and seen a lot of stuff on popping sounds at high revs ive changed the plugs about 2 times and each attempt was a failure ive checked the coil packs they seem to be fine they have no cracks in them or anything the first time i pulled the plugs out they were a bit white on the ends with those plugs the car only popped at high revs then a funny thing happened the popping went away but accelleration was retarded throttle felt sticky every thing felt real sticky wasnt blowing off properly but you you could pretty much redline it every gear 9 outta 10 times then a week later that stopped throttle felt better but popping came back changed the plugs again and cleaned all the pipes and throttle body put plugs back in acceleration was bit better but still got popping at hi revs and a little pop in the low revs around 2000 changed the plugs again i think one of them wasnt spaced right put new ones in any ways i think ngk bcpr7es gapped them at 8mm now the acceleration is alot better engine idles beautiful but i have a major problem i cant oppen the gas right up as soon as i give it full gas it starts popping bad if you give half you can redline it but cant do this fast tottaly a pain in the ass so now the popping noise dosnt sound so much in the plugs more under me in the exhaust bit more of a back fire do you think this could have to do with fuel like maybe its running to lean or something if any one has had any simillar problems could they help me it would be much appreciated

My mate had this same problem, it turned out to be the coil packs. Get a shit heap of insulating tape and tape up the stems, and grab some araldite and fill in any cracks. You can give that a try, otherwise you are up for a few new coil packs.

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      By nouveau_poor · Posted

      Hi everyone, I've been wrestling with this for a while now and have been trying to find out the cause. For context, the turbos used are Garrett 2860 -5s, the BOV is a BNR32 HKS SSQV IV kit, the car is currently tuned to ~470 whp on 17.5 psi. The car drives normally, pulls well when it doesn't happen, and I can replicate it fairly easily. It does not sound like turbo shuffle or flutter. The engine has only a thousand or so miles and has had this behavior since it was completed. After my engine was built for my R32 GTR, I noticed that the car now sometimes makes an air discharge sound on what appears to be positive boost pressure that sounds really similar to a BOV. I had thought that it was a BOV issue but even when replacing it with a brand new unit, the sound persisted. It seems like it's coming from the passenger side but I may be mistaken. The closest scenario I could find was this post here https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/ started by @yakshii and it sounds very similar. As in, at partial throttle once I reach positive boost I begin to hear the same psh psh psh psh psh sound like air is leaking somewhere when I keep the throttle in the same position. It most commonly happens in 4th gear at around 3-3.5k RPM and 5th gear around 2.5-3k RPM, which seems to coincide with normal positive boost thresholds. It might be similar to what @Austrian GTR mentioned about his own HKS SSQV. Notable difference would be that when he applies more throttle when it happens, it stops. In my scenario if I apply more throttle during this repeated psh psh psh sound, the cadence of the sound gets faster and louder rather than stopping. If I lift off slightly and apply throttle again, it will normally stop and pull without issue. I've checked all rubber couplers to ensure that they are tight, but have not gotten the opportunity to properly do a pressurized boost leak test. If anyone has had similar experiences or thoughts on what might be the cause, I'd be very keen to hear them. I also have a video of it happening from inside the cabin, if that would make it easier to understand: https://youtu.be/2zqZXcx8jbA

      That's incorrect. We have 4 seasons, consisting of pre winter, winter, post winter and a small glimpse of hope!
