Hey,

I just installed a temporary boost gauge on my r32 gtst which is absolutely stock, the only mod being a redline panel filter. Basically these are my results;

Full throttle in 3nd spikes to 11psi holds 10 psi till about 5300rpm and drops back to 8psi, pretty much got the same result through 2-3-4 gears

Is this normal? only reason i ask is because everyone i speak to reakons all the skylines (r32,r33) only run 7psi but its holding 10psi for a pretty long time, not just spiking upto 10.

Your feedback would be appreciated

P.S done on a 15 degree night.

When Mine was stock it ran 9psi of boost.

After the 3" turbo back exhaust it now runs 10.9psi and doesn't drop off.

If I run over 12.5psi of boost it will drop back to 12.5psi over 5500rpm.

I have since redrilled the holes in the wastegate bracket and pulled the wastegate towards the front of the engine bay effectively reducing its travel. After a little bit of fiddling and some nasty boost/afm cuts I've got it holding 16psi until just over 7000rpm where I grab the next gear.

I've also used a gated bleeder to bring boost up a little quicker in the mid range. With just the bleeder as I said it will drop back to 12.5psi.

By doing the wastegate mod it dropped my 0-100times from around 5.6secs to 5.2secs. I can get it doing 5.2secs to 100km/h consistently. Providing the road surface is nice.

      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.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.

      I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.

      If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
