So I think ive watched every RB video on youtube haha. There is a very specific sound that I would like to get from my rb25 but I cant seem to pinpoint exactly what brings out this sound from these engines. It might sound crazy but the sound of these engines was one of the primary reasons for my choosing it over a JZ engine for my swap, so I want to get the exact sound from it that I like. Its hard to get much tech info from any sources here in the states so I figured you guys would be the best to ask. As far as I can tell from videos it doesnt really matter if its an rb26, rb25, rb30, or rb25neo, they all sound pretty much the same given the same setup.

Here are a couple standard sounding RBs, im sure you all know what an RB sounds like but I guess ill put these here to kind of set a baseline. Just your average RB sound

I really like this one, but not quite the sound im talking about

This one is getting closer but still not there

And here is the sound im trying to achieve, its kind of a crunchy screaming wail and higher pitch than the previous videos.

Does anybody know what these cars might have in common in the engine/exhaust that give them this sound? They seem to be straight pipe but I dont think this is the main thing that gives the sound.

Thanks

See at first I thought it had something to do with a larger than normal exhaust (straight pipe of course), like running a 3.5" instead of 3". But ive watched some videos of cars with 3.5" and even 4" that dont seem to get this sound.

I have a twin scroll tubular manifold waiting to go on, and ill be running a borg warner s366.

Did you watch the videos? Its definitely not the wastegate(s), I had planned to do atmospheric dumps on my wastegates but I know that wont get me the particular sound im after. There is a distinct difference between the first set of videos and the second.

Im sure this post/thread comes off as ricey but I know what im doing and the exhaust sound is important to me. I really dont want to spend a ton of money and time fabricating/re-fabricating parts to get the sound im after. I was hoping someone who has been around a lot of RB cars would be able to identify and give some experience based input to what kind of setups produce this particular exhaust sound. There arent any other RB cars in my area, and really not a lot in the USA compared to other countries. Its hard to track down information that I would usually be able to collect by just going to the dragstrip and asking people about their setups.

It's not ricey, but it is pretty stupid.

You've chosen your turbo and manifold. You want to run straight through exhaust. But you want to make your car sound like those? Well, does that mean your willing to change turbos, manifolds, wastegate size for the sound?

If so, then spend your time emailing the people who own the cars in the vids and ask their setup, instead of playing guessing games on a forum.

If not, put your flaming car together with a 3.5 inch exhaust, fabrication which means you can either plumb back or vent to atmosphere the wastegates. Then go drive it!

Two other points.

You're placing all of your faith in sound shot off camera phones and goPros. Ever listened back to a recording off one of those and thought it sounded exactly like the real thing?

Also, RBs sound completely different. A 26 doesn't sound like a 25, which doesn't sound like a 30.

I wouldnt say its stupid, why cant I have the sound that I love so much? The sound of these engines really is one of the primary reasons im staying with it. I could easily swap it out for a 2JZ and spend a ton less money making big power. I want to run a straight through exhaust because I think that is something all these cars have in common, normally I would prefer a resonator at least. I like a loud exhaust but im not one to try and have an insanely loud exhaust. I am willing to change turbos (within my power goals) and fabricate another turbo manifold if I knew exactly what features contributed to the sound I am trying to acheive. I have also tried contacting the people with these cars but no success, asking here was a last ditch effort because I figured the guys on here have been around a lot of RBs and might be able to easily give some info on the subject.

I can see your point but the sound I am hearing is so distinct that I know its not just a microphone/speaker inaccurately re-producing it. I have heard this exhaust note from all three platforms you mentioned so I know its not tied to the displacement base.

Thanks for the link, I couldnt find in the thread but do you know what exhaust manifold he is running. And is that car straight pipe?

Like this?

Get one of these:

Yes thats it, do you mean one of those manifolds in particular or a tubular manifold in general?

I have this one right now but id be willing to fab up one with a different design if that has something to do with it.

Here man, this skyline sounds really similar to the sound your looking for. Imo, i reckon this sound sounds much better then the one your looking for, sounds exactly like the r34 gtr from 2 fast 2 furious. In the vid description he posts down exactly what hes done to the car to get that sound. So you could potentially go for this sound, maybe it could help you with the sound your looking for.

But yeah, i reckon go for this sound man, it sounds so epic, i wish i could get my r33 to sound like this.

It sounds good but id say thats more of the standard RB sound, really just playing with mufflers to get the exact note you want.

I think niZmO_Man is on to something, those manifolds looked kind of like 6boost so I started youtubing 6boost mani cars and they all seem to have the sound I want. Im thinking that the runner length and arrangement of the 6boost manifold might be whats getting this sound. Thanks for your response niZmO_Man :)

The manifolds I posted are R31 GTS-R style. R31House make new ones.

IMO, that's what you want. The long runners gives it that awesome sound up in the rev range.

The 6boost is similar. They make high mount and low mount I believe. There is a company in NZ that does a high mount, Sinco I think it is. The one you have is a Full Race manifold?

Ok I think that has it pretty much solved. Thanks a ton for the help niZmO_Man :)

The manifold I have right now is an AFI Turbo, its very similar to the full-race. It will probably be up for sale soon haha, ill probably buy a sinco unless its a pain to ship from NZ in which case ill just build one based on 6boost/sinco design.

    • This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.
    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
