yes its the synchros

common problem with skylines dont let it worry you too much

try changing the gearbox oil, and if you are really desperate to fix it put in redline oil which costs about 3 times as much as most other stuff but seems to work (stopped crunching for me)

mad, ill try the redline oil. What would be a rough estimate on how much its worth?

redline lightweight shockproof = $120 for 4 litres

p.s. probably nothing to do with synchros, everybody blames them. We have rebuilt a few gtr boxes and found the selector hubs wear causing the crunch not synchros. WHY DOES EVERYBODY BLAME SYNCHROS????

because most people dont know what selector hubs are, but we have all heard of synchros and what their purpose is, therefore if a gear doesnt engage smoothly, then, IS GOTTA BE DA SYNCHROS MATE!!!! :P

      Do Alan and Keith work on Skylines now? I remember buying stuff from them when I owned my Ralliart Lancer a few moons ago. Definitely genuine guys and be excellent if they dealt with the skyline platform as well.

      Hey all, I'm Gaston from Sydney's West.  I was a member on here when I was a younger lad and owned a mint R33 GTS-T. Ended up selling it and getting married having kids (yadda yadda) we all know how the story goes. Now I'm back with the intention to get my midlife crisis (dream) car ... a R35 GTR.  You'll see me about asking questions and searching the forums. Good to be back and can't wait to get back an Import again.

      I have to put something here in order to post the photos. From what I could gather there's more enthusiasm for modified cars now than there has been for years. There were probably more younger people there than older (me included lol) which was a good sign.  It did seem like the record least amount of representation of the 90's era hero cars on display though. Like maybe one or two examples of S-chassis Nissans, and maybe 3 or 4 R-chassis. By comparison there were a lot of Civics from that era but in all there were about 10 - 12 EG/EK Civic Type R.  Euro exotics are always there in large numbers, led by Liberty Walk...... say what you will about kids using markers to scribble on a Ferrari F40, it did seem like a stunt to infuriate Ferrari enthusiasts, or Ferrari itself. I wonder if there's something more to it. Either way LBWK have done some heinous things to a Lamborghini Miura this time. They should stop now.

      Engines and drivelines are not war stoppers for me mate, busted arse bodies and un-obtainium parts and panels are though Both cheap Brumbies I looked at had trashed tubs and a fair bit of rust

      Stock O2 sensors are narrowband. They're useless once you're away from stoich. IE, useless for what you're trying to do. 10:1 will read the same as 14:1 from the stock O2 sensors. That is, they'll read rich. The same level of rich.
