Yeh you're right the GTST's and GTR's don't sound exactly the same. My first Skyline was a GTST of the same year and I must admit it did have quite a note before I got busted for it haha! Lets just say it took a lot of work to bring it under 90db again lol!

Yeh I might even post up a vid of it hey? I got the old sound....just need to take some "footage" of the drone.

There's no reputable tuners in my area ;-)

good idea..

get someone to drive it past whilst you record it & place the camera 2M away from the car whilst your car is stationary and rev it a bit.

yeah well the supra i mentioned before, i got tested between 130 - 140db..and i had never gotten busted for the 3 years ive owned it.

looking forward to seeing your video

OK, I've posted up a video just for this thread! Listen to that rumble haha! Well, the rumble it had before the twin to single conversion.

Now I just need to get some footage of the drone although you could just listen to one of those ricer boys with their milo tins ;-) Sounds just like it lol.

It did have a nice ring to it hey? Now you know why I posted....because with my turbo conversion that all disappeared.

I guess it's a matter of opinion too:

...some people care only about getting from point A to point B. Then you got those who only care about the look and sound of their car....you know, the all-show-no-go type. Then you go the opposite of that where people build brutal machines that set lap records and don't really mind what they look or sound like......and then finally, I guess you have my catagory - a slightly built up GTR for track and road use....nice looks and wanting nice sound too, so the whole thing really.

But yeh I'll try to capture some "drone" ;-)

well if it were me i wouldnt care too much about the sound

depends on how your car really sounds like......

it probably doesnt sound bad at all but your just not used to it?

yeah highly modified cars can sound very different

this 7 sec supra for e.g... ive noticed anything over the 1000hp range they start to sound like a Tractor rather than a car...

listen to this supras idle..

If it was just a different note then that would be OK....but in my case it not only has a different note but it has quite some drone to it. Oh yeh, that's true - the more HP the less they sound like what they did with just factory type power. Yep, that supra idles nothing like the normal ones hehe....but then that ain't quite a supra anymore! It's more like 10 supras in 1 lol!

I went for a little spin around the block before and got a dose of drone on camera....just waiting for the video to become active. Will post the link when it's good to go. You'll have to watch it straight after you watch my other one - quite a difference!

:down:

gee

that sounds awsome!

if there is no loss of power i dont think theres anything wrong, it may be what you were saying in the first place, the design of the turbine & size.

ive heard T88 & T78 supras and GT-Rs and they do sound different to stock.

id love that sound....that doesnt sound like no shitty non turbo 4cyl dude....

im guessing it sounds a bit better in real life?

the "droning" sound...are you describing it as the low pitch gurgle?

if so, thats just the nature of the turbocharger.

if you really care about sound, something you might wana look at in the long run would be aftermarket cams...

they play a big role in a cars exhaust note.

LOL I knew you'd say that. Well, the first part of the video is just the exhaust in idle in the garage and like I said earlier, it still sounds half decent under around 1500rpm or so. I used my own shitty camera for this so it didn't pick up the droning part of the movie as well as I hoped. It's hard to explain really and it would be so much easier if you one could just go for a spin ;-)

By the way, when there's no load on the engine and you free-spin it up to like 3000 or so like I did in the video it won't drone....it's only when I'm driving and when the engine is at work that it drones its head off :) (Did you watch the driving bit in the movie?)

the "droning" sound...are you describing it as the low pitch gurgle?

if so, thats just the nature of the turbocharger.

Nope it's that "gurgle" sound that I love - it's unique to the RB series engines and from it you can tell there's a Skyline nearby :(

In my first video where I'm driving to the pits you can hear the sound there and it would continue like this all the way through the rev range...it was music!

In the clip you'll notice that it no longer does the "gurgling" during normal cruising like it used to with the twins.

But yeh, to anyone else reading this - don't get me wrong - it's not a bad thing.....I'm just hoping that someone who's noticed exactly the same thing may have done something with their exhaust to minimize the drone and bring out some of that old sound when driving etc. Please check out my two comparsion videos put up just for this thread/question:

Sound after twins were replaced with GT35r (please watch this one all the way through)

yeah i listen to it all the way

the video sound is very muffled

but i personally dont think theres anything wrong

i take it that your just getting used to it, aftermarket turbos do make a change to the note

yeh would be nice if you could set up a video outside.....whilst driving...

set it on a Kerb outside and drive past it on the opposite side of the road.

awsome! :thumbsup:

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
