Its stock internals except exhaust cam, on 0.9 bar still just as response and enough power. Its IT 50, what does all that stuff mean? BP:99.0 RH:25 AT:39 IT:50 RR:013 TN:3.768 CK:726? I have heaps of wheel spin all the way through first gear, does anyone now how to best set up the car and what tyres to use to get more grip. I have tein super street coilovers set 3cm lower and its shocks at 8 out of 16 also have whiteline handling kit with sway bars and bushes to reduce camber by 0.75 degrees in rear.

Reedy very nice, are the internals of your RB25DET standard?

Can anyone tell me how their GT-RS performed at lower boost such as 0.8 or 0.9bar, apart from lower power output, still responsive?

Boost i got 210rwkw on 0.8bar which is pretty much standard boost. on that it seems a little laggier but top end it still goes.

IT = Inlet Temperature

AT = Ambient Temperature

RH = Relative Humidity

RR = Ramp Rate

BP = Barometric Pressure

CK = Check sum (formula to validate these settings)

Re traction problems, Teins, what's the rear spring rate? Usually I find it WAY to high. Anything over 200 lbs per inch (3.5 kg/mm) is too much.:P

The engine light will also come on if your AFM maxes out. If you are running 1.3 bar with the standard AFM then it will max out for sure.

Just took it out for a run now, first cold night since i got it. on 1.3 bar boost at high rpm engine cut-out light comes on, was told that this is pinging although i cant hear anything. going to run it back on dyno to set timing back a few degrees.

I am sure thizzle made 250kw @ 1.3 bar, it is impossible to make it at 1 bar.

      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!

      RB20DE NEO smallbox clutch.

      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.

      Lock up the old for sale / wtb threads.

      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.
