im not exactly sure if this is what ur talking about but that mechanical noise i assume ur describing is the turbo spooling up. There are very few of us NA boys out there so id say everytime u see/hear a skyline it is most of the time a turbo.

I not sure what you are talking about but...

here is a video clip of my R33 GTS-4 revving up at the light.

its Gun metal Grey with SDU (skylineDownUnder) sticker at the back... its abotu half way of the clip after R31 sleeper :(

I loved the sound of my sky.. pretty loud compared to Turbo cars cuz you know why... :D

i think there are some sort of pod filters available with a plastic cover over them that whistle as air is sucked through them if u want that kinda sound, though they look fairly restrictive to me, not sure what brand either.

heres a few ideas ive heard, to get a nice exhaust note drill a hole through ur exhaust pipe before the muffler, get a bit of guutar string and tack weld it thourgh the pipe, voila u have a wonderful note! another one was to stick a PC fan before the muffler and ull get a turbo whistle lol, never tried it doubt i will! i was gonna try putting a whistle (from those vortex things) in the pod filter before the AFM, lame ;)

I think what streamer was referring to is the difference between the noise of an NA exhaust and the noise of the turbo exhaust...

The NA has a mechanical "zing" sound to it, which I don't ever want to give up even if my exhaust is inefficient.

The turbo has a much lower quieter sound due to the greater flow/less restriction.

correction... its due to its length of the exhaust...:P

Longer pipe = Lower pitch (Bass)

short pipe = hight pitch

add- Longer pipe >(greater) restriction

      Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
